Background The purpose of this study was to determine the prevalence and pattern of ocular injuries among industrial welders and rate the use of protective eyewear at work among industrial welders in Port Harcourt. Information from this study will provide a database for effective policy formation on prevention of occupational eye injuries in Port Harcourt Rivers State. Methods A cross-sectional survey of ocular injuries and use of protective eyewear among industrial welders in the Port Harcourt local government area of Rivers State, Nigeria, was carried out over a three-month period. Five hundred welders were selected by simple random sampling. Information was obtained using an interviewer-administered questionnaire. All welders were examined in their workshops. Results Flying metal chips were the chief source of ocular injury, as reported by 199 (68.15%) of those who gave a history of work-related eye injury, while arc rays accounted for the remaining 93 (31.85%). There was a high level of awareness of the risk of sustaining an eye injury from welding (n = 490, 98%), but only 46 (15.3%) of the welders were using protective eyewear at the time of injury. Conclusion To minimize ocular injury and promote eye health amongst industrial welders, safety intervention programs, such as awareness campaigns, setting up of targeted programs by the relevant government agencies, and encouragement of locally produced eye protectors is recommended. The involvement of occupational medical practitioners is also strongly recommended. PMID:21966197

To evaluate The Community Health Worker "promotor de salud" (CHW) model is evaluated as a tool for reducing eye injuries in Latino farm workers. In 2001, 786 workers on 34 farms were divided into three intervention blocks: (A) CHWs provided protective eyewear and training to farm workers; (B) CHWs provided eyewear but no training to farm workers; (C) eyewear was distributed to farm workers with no CHW present and no training. Pre- and post-intervention questionnaires demonstrated greater self-reported use of eyewear in all blocks after the intervention (P < 0.0001), with Block A showing the greatest change compared to B (P < 0.0001) and C (P = 0.03); this was supported by field observations. Block A showed the greatest improvement in knowledge on questions related to training content. CHWs were an effective tool to train farm workers in eye health and safety, improving the use of personal protective equipment and knowledge.

We investigated sleep quality and melatonin in 12 adults who wore blue-light shield or control eyewear 2 hours before sleep while using a self-luminous portable device, and assessed visual quality for the two eyewear types. Overnight melatonin secretion was significantly higher after using the blue-light shield (P < 0.05) than with the control eyewear. Sleep efficacy and sleep latency were significantly superior for wearers of the blue-light shield (P < 0.05 for both), and this group reported greater sleepiness during portable device use compared to those using the control eyewear. Participants rated the blue-light shield as providing acceptable visual quality.

Ultraviolet and short wavelength visible light exposure: why ultraviolet protection alone is not adequate.

Reichow, Alan W; Citek, Karl; Edlich, Richard F

2006-01-01

The danger of exposure to ultraviolet (UV) radiation in both the natural environment and artificial occupational settings has long been recognized by national and international standards committees and worker safety agencies. There is an increasing body of literature that suggests that protection from UV exposure is not enough. Unprotected exposure to the short wavelengths of the visible spectrum, termed the "blue light hazard", is gaining acceptance as a true risk to long-term visual health. Global standards and experts in the field are now warning that those individuals who spend considerable time outdoors should seek sun filter eyewear with high impact resistant lenses that provide 100% UV filtration, high levels of blue light filtration, and full visual field lens/frame coverage as provided by high wrap eyewear. The Skin Cancer Foundation has endorsed certain sunglasses as "product[s]...effective [as] UV filter[s] for the eyes and surrounding skin". However, such endorsement does not necessarily mean that the eyewear meets all the protective needs for outdoor use. There are several brands that offer products with such protective characteristics. Performance sun eyewear by Nike Vision, available in both corrective and plano (nonprescription) forms, is one such brand incorporating these protective features.

Photobiology eye safety for horticultural LED lighting: Transmittance performance of eyewear protection using high-irradiant monochromatic LEDs.

PubMed

Wu, Bo-Sen; Lefsrud, Mark G

2018-02-01

Light emitting diodes have slowly gained market share as horticultural lighting systems in greenhouses due to their rapid improvement in color performances and light outputs. These advancements have increased the availability of the full spectrum of visible wavelengths and the corresponding irradiance outputs available to plants. However, light emitting diodes owners have limited information on the proper options for personal eyewear protection as the irradiance levels have increased. The objective of this study was to measure the light transmittance performance of 12 eyewear protection including welding goggles, safety goggles, polarized glasses, and sunglasses across the human visible spectrum (380-740 nm) up to an irradiance level of 1500 W·m -2 from high-irradiant light emitting diodes assemblies. Based on the spectral measurements, certain transmitted spectra exhibited spectrum shifts or an alteration in the bimodal distribution which were different than the light emitting diodes spectra, due to the uneven transmittance efficiencies of the glasses. As for the measured transmittance percentages in two experiments, each type of eyewear protection showed distinct transmittance performances, and the performance of the tested eyewear protection was not impacted by irradiance but was dependent on the wavelength. The mean light transmittance was 1.77% for the welding glasses, 13.12% for the polarized glasses, 15.27% for the safety goggles, and 27.65% for the sunglasses. According to these measured results and the spectral weighting exposure limits from the International Electrotechnical Commission 62471 and EU directive 2006/25, consumers and workers using horticultural lighting can select welding goggles or polarized glasses, to limit the possible ocular impact of the high irradiance of monochromatic light in electrical lighting environment. Sunglasses and safety goggles would not be advised as protection, especially if infrared radiation was used.

Effect of Chromoendoscopy Filters on Visualization of KTP Laser-Associated Tissue Changes: A Cadaveric Animal Model.

PubMed

Johnson, Christopher M; Pate, Mariah B; Postma, Gregory N

2018-04-01

Standard KTP laser (potassium titanyl phosphate) wavelength-specific protective eyewear often impairs visualization of tissue changes during laser treatment. This sometimes necessitates eyewear removal to evaluate tissue effects, which wastes time and poses safety concerns. The objective was to determine if "virtual" or "electronic" chromoendoscopy filters, as found on some endoscopy platforms, could alleviate the restricted visualization inherent to protective eyewear. A KTP laser was applied to porcine laryngeal tissue and recorded via video laryngoscopy with 1 optical (Olympus Narrow Band Imaging) and 8 digital (Pentax Medical I-scan) chromoendoscopy filters. Videos were viewed by 11 otolaryngologists wearing protective eyewear. Using a discrete visual analog scale, they rated each filter on its ability to improve visualization,. No filter impaired visualization; 5 of 9 improved visualization. Based on statistical significance, the number of positive responses, and the lack of negative responses, narrow band imaging and the I-scan tone enhancement filter for leukoplakia performed best. These filters could shorten procedure time and improve safety; therefore, further clinical evaluation is warranted.

Modeling and characterization of dye-doped guest-host liquid crystal eyewear

NASA Astrophysics Data System (ADS)

Coutino, Pedro Coutino

This thesis explores the use of dye-doped guest-host liquid crystals in variable transmission eyewear devices that protect against rapid and abrupt changes in lighting conditions. Some of their unique characteristics such as millisecond time response, low power consumption, fail-safe operation, and wide color palette make them the only available technology that meets the basic requirements for fast, adaptative eyewear applications. Despite these unique features, there are limitations in the technology which have hindered its use for more advanced eyewear applications. It is the aim of this dissertation to explore these limitations and provide experimental and numerical characterization tools necessary to surpass them. First, several techniques are described to evaluate materials and devices performance in terms of their photopic transmission, haze, birefringence, and distortion. The results are used to demonstrate that by choosing and combining the right materials, it is possible to improve the optical quality of the eyewear. Then, a simulation instrument which combines and integrates all the necessary elements to model the electro-optical response of dye-doped guest-host liquid crystal eyewear was constructed. This program is capable of reproducing with high accuracy experimental results, to predict the performance of devices, and to mimic the spectral curve of a target color. Numerical experiments were performed to study some of the most common limitations of the e-Tint mode or single cell technology including photopic transmission window, and polarization dependence and demonstrate that optimizing parameters such as birefringence, d/p, and concentration of dyes helps to overcome these limitations and enhance system performance. A guest-host double cell system is proposed as a new alternative mode for most advanced eyewear applications. Particular attention was placed on a switchable crossed polarizers configuration which offered superior optical characteristics such as extremely low polarization dependence and increased transmission window. Simulations showed that the same effect can be obtained for other non-zero d/p values, by proper choice of chirality and configuration. Furthermore, a unique four-color eyewear was designed by combining the absorption properties of individual cells. Finally, several state-of-the-art military and commercial dye-doped guest-host eyewear applications which make use of all the results obtained during this dissertation are presented.

We examined the effect of equipment proximity on the safe performance of 3 assembly workers in a manufacturing setting. After a baseline period in which protective eyewear was kept 6.1 m from employee workstations, task clarification was used to inform participants to wear their eyewear while they worked. Next, the eyewear was moved to 1.5 m from employee workstations. After a return to the 6.1-m condition, the eyewear was again positioned 1.5 m from workstations. Results indicate that task clarification alone was ineffective, but safe performance increased when eyewear was stored in close proximity to employees. A social validity measure suggested that safe performance among the employees increased to levels comparable to that of an exemplary employee. © Society for the Experimental Analysis of Behavior.

Reduction of protection from laser eyewear with ultrashort exposure

2001-07-01

We have measured the optical density of various laser eye protection samples as a function of increasing irradiance. We show that the protective quality of some eyewear degrades as irradiance increases. In previous studies this problem has been demonstrated in samples irradiated by nanosecond pulses, but the current study shows that the modern laser eye protection seems to be robust except for the irradiance possible with ultrashort laser pulse exposure. We discuss the most likely saturation mechanisms in this pulse duration regime and discuss relevance to laser safety.

The purpose of this study was to determine the effectiveness of preventing eye injury with the use of safety eyewear in agriculture workers. A sample group of 575 agricultural workers (Group A) engaged in harvesting paddy were provided with goggles with side covers. Following harvesting, a questionnaire-based survey was carried out to determine the frequency of their eye injuries. Workers with goggles were asked about the duration for which they used the goggles and also list barriers or difficulties with the same. The frequency of eye injuries in this group was compared with another group of agriculture workers (Group B) who did not use any safety eyewear. The frequency of eye injuries in Group A was 4 (0.7%) and Group B was 61 (11.3%) which was highly significant (P = 0.0001). The relative risk calculated was 0.06 (95% confidence interval: 0.02-0.2). Agricultural workers in Group A had 94% less risk of ocular trauma compared to those in Group B. Injuries in both groups were caused by parts of the paddy plant. A significant number (76.2%) of workers used the goggles all or most of the time during work. Impaired vision when wearing goggles was the most frequent barrier reported by the workers. Other barriers were discomfort, shyness, forgetfulness, apathy, slowing of work pace, awkward appearance, and breakages. Safety eyewear conferred significant protection against work-related eye injuries in agriculture. Although safety eyewear was widely adopted by the workers, barriers reported by them will need to be addressed to make such programs more effective.

Eye irritation is a constant hazard for migrant and seasonal farmworkers, but there are few studies of the problem or how to address it. Researchers evaluated the effect of a community-based participatory eye health intervention on farmworker eye symptoms in the Hudson Valley, NY. A randomized pre-post intervention with 2, 4-week follow-up periods was implemented with a sample of 97 farmworkers. Five eye symptoms were measured, along with utilization of protective eyewear and eye drops. Leading baseline eye symptoms were redness (49%), blurred vision (43%), itching (43%), and eye pain (29%). Significant reductions in eye pain (P = 0.009), and non-significant reductions in redness were observed for the intervention group while controls experienced increases in both. The intervention was effective in significantly reducing eye pain, and to a lesser extent, redness. Future eyewear promotion programs should offer a range of eye wear, tailor offerings to local climate and tasks, evaluate eyewear durability, and include eye drops. © 2014 Wiley Periodicals, Inc.

AIM To investigate the incidence and general characteristics of sports-related eye injuries in patients visiting the Emergency Department. METHODS A cross-sectional, multi-center, observational study. Patients with an injured eye who visited the Emergency Department at one of nine hospitals in Korea were enrolled. All data were prospectively collected between March and September 2010 using a questionnaire. Eye injuries that occurred during risky sports were examined by gender and age. Additionally, the rate of open globe injuries that occurred with and without protective eyewear was examined for each activity. Continuous variables were compared using Student's t-test and categorical variables were compared using Chi-square test. RESULTS A total of 446 patients had sports-related eye injuries. Teenagers (10-19 years old) and young adults (20-29 years old) had the most eye injuries. Eye injuries accounted for 0.2% of Emergency Department patients. Baseball was the most common cause of sports-related eye injuries, followed by soccer and hiking. Protective gear was worn by 9.4% of all patients. Patients that were 30-39 years of age had the highest rate of protective gear use, followed by patients that were 40-49 years of age. The proportion of sports-related eye injuries that were open-globe injuries was highest for soccer and hiking. CONCLUSION Although injuries were most common in patients below the age of 10 years, these patients had the lowest rate of protective eyewear use. Injuries in adults over 40 years of age most commonly occurred during hiking, but the rate of protective eyewear use was low. Young athletes should be educated on and provided with protective eyewear and policies protective gear use should be established. For older adults, eye protection should be encouraged, especially during hiking. PMID:27803871

Compared to other health-care workers, dental health-care workers come in close contact with patients and use a variety of sharp and high-speed rotating instruments. It is important to understand the characteristics of the occupational accidents that occur. We reviewed incident reports from April 1, 2005, to March 31, 2010, at Matsumoto Dental University Hospital. In addition, questionnaires dealing with identification of occupational safety issues, especially splash exposures, were conducted for dentists, dental hygienists, and nurses. Thirty-two occupational injuries were reported during the study period, including 23 sharp instrument injuries (71.9%), 6 splash exposures (18.8%), and 3 others. Of the six splash exposures, only two cases involved potential contamination with blood or other potentially infectious patient material. Of the 66 workers who experienced sharps injuries, 20 workers (30.3%, 20/66) reported them to the hospital work safety team. The questionnaire revealed high incident of splash exposures and conjunctiva exposures: 87.9% (51/58) and 60.3% (35/58) in dentists and 88.6% (39/44) and 61.4% (27/44) in dental hygienists. The compliance rate for routine use of protective eyewear was 60.3% (35/58) for dentists and 34.1% (15/44) for hygienists. Of the presented informational items included in the questionnaire, those that strongly persuaded respondents to use protective eyewear were 'splatters from the patient's mouth contain blood' (90%, 99/110) and 'dental operations at our clinic are performed based only on a questionnaire without serious examinations for HBV, HCV, and HIV' (71.8%, 79/110). The reason of low compliance of protective eyewear among dentists might relate to fine dental procedures. Appropriate information is important for the motive of wearing personal protective equipment, and an early educational program may have a potential to increase compliance with the use of that equipment.

Army aircrew are required to operate under stressful conditions within a degraded visual environment. To gain an understanding of current eyewear mission needs, we surveyed aircrew regarding operational issues associated with the current U.S. Army-issue aircrew eyewear. An anonymous online survey was completed by 976 U.S. Army aircrew personnel recruited through an invitational e-mail. Of the respondents, 34% reported wearing corrective lenses. Nearly 50% of them reported dissatisfaction with the HGU-4/P Aviator spectacles. The leading problems reported were discomfort (15%), "hot spots" around the ears (13%), and break of the earcup seal (11%). Nearly 41% of the respondents wore multifocal lenses and, of those, 16% reported that the HGU-4/P's restricted field of view (FOV) adversely affected duty performance. Of those who wore Modified HGU-4/P Apache spectacles, 79% had an unacceptable FOV with the helmet display unit. A similar number of aircrew modified the Apache eyewear to increase the FOV. In addition, wind and dust created eye discomfort or affected the vision of 46% of all respondents when performing flight duties. Over 82% expressed the need for an improved aircrew spectacles and 73% desired aviation-compatible protective eyewear. The current Army HGU-4/P Aviator and the Modified HGU-4/P Apache spectacles have significant operational deficiencies and compatibility issues. Such deficiencies have led to poor wear compliance and unauthorized modification of the Army-issue Aviator eyewear, posing readiness and safety issues. The results of this survey formally identify the need for military combat eye protection that is compatible with flight systems.

Ultrasonic scaler is a preferential treatment modality among the clinicians. However, the aerosol/splatter generated is a concern for patients and practitioners. Therefore, the purpose of this study was to evaluate contamination of contact lenses of the dentist after scaling and root planing using ultrasonic scalers with and without protective eyewear. Thirty patients were randomly selected for scaling and root planing and divided into 2 groups of 15 each. Group A - dentist wearing contact lenses and protective eyewear. Group B - dentist wearing only contact lenses. After scaling and root planing using ultrasonic scalers, the lenses were subjected to culture and 16S rRNA (16S ribosomal RNA) gene sequencing. In Group A - 15 out of thirty samples were contaminated, in Group B - all the thirty samples were contaminated. Most of the samples showed Gram-positive bacteria and 5 samples were contaminated with fungi. 16S rRNA gene sequencing of forty contaminated samples showed that 31 were contaminated with Streptococcus mutans and 9 with Staphylococcus aureus. Keeping in mind the limitation of the study for the absence of negative control, we would like to conclude that dental practitioners should better avoid contact lenses in a dental setup because of the risk of contamination of the contact lenses from the various dental procedures which can produce aerosol/splatter and if worn, it is recommended to wear protective eyewear.

Femtosecond lasers, with pulses naturally possessing broad-bandwidth and high average power with variable repetition rate, can exhibit spectral side-bands and subtly changing center wavelengths, which may unknowingly affect eyewear safety protection. Pulse spectral characterization and power diagnostics are presented for a 80 MHz, Ti+3:Sapphire, ≈ 800 nm, ≈40 femtosecond oscillator system. Power and spectral transmission for 22 test samples are measured to determine whether they fall within manufacturer specifications. PMID:29353984

Of the presented informational items included in the questionnaire, those that strongly persuaded respondents to use protective eyewear were ‘splatters from the patient’s mouth contain blood’ (90%, 99/110) and ‘dental operations at our clinic are performed based only on a questionnaire without serious examinations for HBV, HCV, and HIV’ (71.8%, 79/110). The reason of low compliance of protective eyewear among dentists might relate to fine dental procedures. Appropriate information is important for the motive of wearing personal protective equipment, and an early educational program may have a potential to increase compliance with the use of that equipment.

Do modern spectacles endanger surgeons? The Waikato Eye Protection Study.

Despite documented cases of infectious disease transmission to medical staff via conjunctival contamination and widespread recommendation of protective eyewear use during surgical procedures, a large number of surgeons rely on their prescription spectacles as sole eye protection. Modern fashion spectacles, being of increasingly slim design, may no longer be adequate in this role. A survey was conducted among the surgeons at Waikato Hospital from December 7, 2004 to February 1, 2005, to assess current operating theater eyewear practices and attitudes. Those who wore prescription spectacles were asked to assume a standardized "operating position" from which anatomic measurements were obtained. These data were mathematically analyzed to determine the degree of palebral fissure protection conferred by their spectacles. Of 71 surgical practitioners surveyed, 45.1% required prescription lenses for operating, the mean spectacle age being 2.45 years; 84.5% had experienced prior periorbital blood splashes; 2.8% had previously contracted an illness attributed to such an event; 78.8% participants routinely used eye protection, but of the 27 requiring spectacles, 68.0% used these as their sole eye protection. Chief complaints about safety glasses and facial shields were of fogging, poor comfort, inability to wear spectacles underneath, and unavailability. Our model predicted that 100%, 92.6%, 77.8%, and 0% of our population were protected by their spectacles laterally, medially, inferiorly, and superiorly, respectively. Prescription spectacles of contemporary styling do not provide adequate protection against conjunctival blood splash injuries. Our model predicts the design adequacy of currently available purpose-designed protective eyewear, which should be used routinely.

Laser technology has significantly impacted our everyday life. Lasers are now used to correct your vision, clear your arteries, and are used in the manufacturing of such diverse products as automobiles, cigarettes, and computers. Lasers are no longer a research tool looking for an application. They are now an integral part of manufacturing. In the case of Class IV lasers, this explosion in laser applications has exposed thousands of individuals to potential safety hazards including eye damage. Specific protective eyewear designed to attenuate the energy of the laser beam below the maximum permissible exposure is required for Class 3B and Class IV lasers according to laser safety standards.

Although eye injuries are common among citrus harvesters, the proportion of workers using protective eyewear has been negligible. We focused on adoption of worker-tested safety glasses with and without the presence and activities of trained peer-worker role models on harvesting crews. Observation of 13 citrus harvesting crews established baseline use of safety eyewear. Nine crews subsequently were assigned a peer worker to model use of safety glasses, conduct eye safety education, and treat minor eye injuries. Safety eyewear use by crews was monitored up to 15 weeks into the intervention. Intervention crews with peer workers had significantly higher rates of eyewear use than control crews. Intervention exposure time and level of worker use were strongly correlated. Among intervention crews, workers with 1 to 2 years of experience (odds ratio [OR] = 2.89; 95% confidence interval [CI] = 1.11, 7.55) and who received help from their peer worker (OR = 3.73; 95% CI = 1.21, 11.57) were significantly more likely to use glasses than were other intervention crew members. Adaptation of the community health worker model for this setting improved injury prevention practices and may have relevance for similar agricultural settings.

Every year > 600,000 sports and recreation related eye injuries occur, out of which roughly 13,500 of these result in permanent loss of sight. Up to 90% of these sports related eye injuries are preventable by using adequate eye protection equipment. Protective eyewear is made of polycarbonate, a highly impact-resistant plastic which is now easily available as prescription and non-prescription eyewear and all players should be encouraged to use them. The medical officers by educating their patients regarding the risks of eye injuries in various sports and the confirmed benefits of using protective equipment have the potential to prevent injury to over thousands of eyes every year. The medical fraternity can also play a very important role in educating the coaches, parents, and children and thus put an end to unnecessary blindness and vision loss from sports related ocular injuries, therefore ensuring a lifetime of healthy vision.

We report a case of globe rupture associated with the use of post cataract-surgery protective eyewear. The patient had routine cataract surgery 3 months before presentation and had adapted his post cataract-surgery glasses to use on the tennis court. He experienced a large posterior globe rupture after falling directly onto his face during a match. Spectacle torsion is the suspected biomechanical process that led to the rupture. We conclude that although the glasses given to many patients after cataract surgery are protective for most low-impact injuries, patients should be aware they are not designed for activities with a risk for significant impact. Patients should also be counseled to use protective eyewear specifically designed and approved for the sport or activity in which they participate.

Moore, Linda A.; Ferreira, Jannie T.

2003-03-01

Sports vision encompasses the visual assessment and provision of sports-specific visual performance enhancement and ocular protection for athletes of all ages, genders and levels of participation. In recent years, sports vision has been identified as one of the key performance indicators in sport. It is built on four main cornerstones: corrective eyewear, protective eyewear, visual skills enhancement and performance enhancement. Although clinically well established in the US, it is still a relatively new area of optometric specialisation elsewhere in the world and is gaining increasing popularity with eyecare practitioners and researchers. This research is often multi-disciplinary and involves input from a variety of subject disciplines, mainly those of optometry, medicine, physiology, psychology, physics, chemistry, computer science and engineering. Collaborative research projects are currently underway between staff of the Schools of Physics and Computing (DIT) and the Academy of Sports Vision (RAU).

Corneal injury from a metallic foreign body: an occupational hazard.

PubMed

Gumus, Koray; Karakucuk, Sarper; Mirza, Ertugrul

2007-09-01

To describe a patient with a corneal injury from a metallic foreign body caused by negligence, and to highlight the importance of measures that must be taken to prevent corneal injuries. A 21-year-old man experienced a foreign body sensation, pain, and redness in his left eye after he cut some iron material without using any eye protection. Slitlamp examination showed a thin, curled piece of iron material stuck into the cornea horizontally. The nasal part had penetrated the nasal tarsal conjunctiva below the upper lid. After removal of the foreign body, the cornea healed without scarring after a short follow-up. A corneal foreign body is a common cause of ocular morbidity and loss of working hours. Most workers do not use protective eyewear during work. By consistently wearing proper safety eyewear, which is the easiest and most effective preventive measure, loss of sight can easily be prevented after an eye injury.

Does Occupation Explain Gender and Other Differences in Work-Related Eye Injury Hospitalization Rates?

2007-01-01

Objective We sought to determine whether demographic differences in eye injury rates persist after adjusting for occupational exposure. Methods On-duty eye injury hospitalizations were linked to occupation among active-duty US Army personnel. Results Eye injury rates were higher for white solidiers, men, and for younger soldiers, even after adjusting for occupational group and specific job titles using multivariate models. Conclusions This finding contrasts with studies of other injuries, suggesting that occupation does not fully account for variations in eye injury risk. Because protective eyewear can prevent most serious eye injuries, we hypothesize that differences in protective eyewear use between men and women may contribute to differences in eye injury rates, although follow-up studies are needed to confirm this. Prevention efforts should consider targeting high-risk demographic groups in addition to high-risk occupations. PMID:15951724

The role of eye protection in work-related eye injuries.

PubMed

Fong, L P; Taouk, Y

1995-05-01

A recent survey of general hospitals by the Victorian Injury Surveillance System found that ocular trauma represented 15% of work-related injuries. As circumstances surrounding occupational eye injuries have been poorly documented previously, their associations to occupation, industry and work-safety practices, including safety eyewear use, need to be identified to develop appropriate preventive strategies for high-risk groups. From a prospective cross-sectional survey of all eye injuries treated at the Royal Victorian Eye and Ear Hospital, work-related cases were analysed for demographic, occupational and safety eye-wear information. Hospital-based data were supplemented by information from WorkCover Authorities and Labour Force statistics to derive incidence and cost estimates. There were 9390 eye injuries during the 18-month survey period; 42% (n=3923) of total and 29% (n=52) of penetrating ocular injuries occurred at work. The most frequently injured were metal, automotive and building trades workers grinding and drilling (41% of outpatients) and hammering (53% of penetrating eye injuries). Automotive workers had the highest frequency for penetrating injuries, and most were exposed to hammering and were also the least likely to wear safety eye-wear. Eye injuries are frequent (10% of work-related injuries) and highly preventable by the correct use of safety eye-wear, a cost-effective intervention that may result in cost savings of $59 million for work-type activities in the occupational and domestic settings in Australia each year.

Industrial accident-related ocular emergencies in a tertiary hospital in Singapore.

Ngo, C S; Leo, S W

2008-04-01

We present a review of industrial accident-related ocular trauma, from the perspective of the emergency setting of a tertiary hospital in Singapore. A retrospective analysis of patients seen by Tan Tock Seng Hospital's emergency ophthalmology service over a six-month period was performed. Data on clinical presentation, cause of injury, use of protective eyewear and subsequent losses of days-of-work were collected via a standardised telephone interview and review of case-sheets. A total of 300 persons presented with a diagnosis of industrial accident-related ocular trauma, out of the 1,460 patients seen during the study period. 95.7 percent were non-residents and the average age was 31 years. 99.3 percent were males. 66.0 percent were provided with protective eyewear, while 44.7 percent of those were non-compliant. The most common types of injuries were superficial foreign body (71.3 percent), chemical injury (10 percent) and blunt trauma (4 percent), while severe injury requiring admission and emergency surgery occurred in 15 cases. Average loss of days of work was 3.4 days. Industrial accident-related ocular trauma comprises a relatively large proportion of the patients requiring ophthalmic review at the emergency service level in Singapore. These patients are mainly young, non-resident men and the injuries were generally minor. These are largely preventable with the use of well-fitting protective eyewear and strict compliance. This would greatly reduce the unnecessary loss of workdays. Therefore, there is a need to review the design, and reinforce the strict implementation of occupational eye safety programmes, especially among non-resident workers.

Occupational open globe injuries.

2001-03-01

Occupational ocular trauma is an important cause of acquired monocular blindness in a rapidly industrialising country like India. Knowledge of the epidemiology of occupational eye injuries is essential to formulate viable industrial safety measures. We retrospectively reviewed all patients with occupational open globe injuries between 1994 and 1998. We documented the circumstances of the injuries, their clinical findings and the use of appropriate protective eyewear at the time of the injury. The visual acuity 6 months after the injury was the final outcome measure. In this study period we examined 43 patients with open globe injuries sustained at the work place. Thirty-four (79.1%) patients were young males. The iron and steel industry accounted for 19 (44.2%) cases while 8 (18.6%) patients each were from the agricultural, mining and other small scale industrial sectors. At the time of the injury, 33 (76.7%) were not wearing the recommended protective eyewear and 6 (13.9%) were under the influence of alcohol. The injuries were mild in 6 (13.9%), moderate in 18 (41.9%) and severe in 19 (44.2%) patients. At the end of 6 months, 2 (4.7%) patients had a visual acuity of 6/12 or better, 4 (9.3%) had a visual acuity of 6/18 to 6/60 and 29 (67.4.%) had a vision of <6/60. Eight (18.6%) patients were not available for follow up. Occupational open globe injuries are usually severe and are associated with a poor visual outcome. Mandatory use of protective eyewear and alcohol-free environment at the work place is likely to reduce the incidence of severe occupational open globe injuries.

Bryce, E; Forrester, L; Scharf, S; Eshghpour, M

2008-03-01

Data on healthcare workers'(HCWs) self-reported knowledge regarding selection of facial protection equipment, usage preferences and compliance are limited. We used a questionnaire on the use of facial protection equipment at a 700-bed adult tertiary care hospital employing approximately 7000 HCWs. Clinical areas targeted were those with frequent users of N95 respirators: intensive care unit, emergency room, respiratory services, and internal medicine. Respiratory therapists were also invited. In all, 137 questionnaires (68.5%) were returned. Most (72.8%) reported that training on the use of facial protection equipment was 'sufficient' to 'excellent'. The PFR95 and 3M 1860 Cone were used most frequently (56%) followed by the 3M 1870 Pocket (42%). While 95% reported having been fit-tested, only 60% were tested annually. PRF95 use exceeded the number of HCWs fit-tested for the item. Overall comfort and compliance scores were 13.6/20 and 21.5/25, respectively, for respirators and 7.7/10 and 18.5/25 for protective eyewear. No relationship between comfort and years of use of either respirators or protective eyewear was found. The results highlight potential failures in effectiveness in the use of personal protective equipment that could compromise HCW safety, and support observations that compliance in the workplace is usually less than in the research setting.

To determine the factors that are associated with the use of protective eyewear (PEW) among cocoa farmers in Ghana, a multistage random sample of 556 cocoa farmers were recruited from four districts in the country. A questionnaire was used to elicit information on the use of PEW and barriers to its use among these farmers. Only 34 (6.1%) participants reported using PEW. Being female, old age and perception of good distance vision was associated with lower odds of PEW use. However, higher educational attainment, application of fertiliser and pesticides were associated with higher odds of PEW use. Participants cited non-availability, unaffordability and ignorance/lack of training as the main barriers to the use of PEW. The low use of PEW could be addressed through ocular health education and occupational health and safety policy initiatives. Published by the BMJ Publishing Group Limited.

The effect of prescription eyewear on ocular exposure to ultraviolet radiation.

PubMed Central

Rosenthal, F S; Bakalian, A E; Taylor, H R

1986-01-01

Several studies have suggested that ultraviolet radiation in sunlight may cause cataracts and other eye disease. We evaluated the effect of prescription eyewear in attenuating ocular exposure to ultraviolet radiation (UVR) in the sunlight portions of the ultraviolet spectrum (295-350 nm). Using natural sunlight as the source, the attenuation was measured with two ultraviolet detectors, one sensitive to only UVB (295-315 nm) and one sensitive to both UVA and UVB (295-350 nm). A random sample of spectacles, spectacle lenses, and contact lenses was examined. The average transmission, as measured with either detector, was highest for soft contact lenses, followed by glass spectacle lenses, untinted hard contact lenses, and plastic spectacle lenses. Measurements performed with mannikins wearing spectacles showed that an average of 6.6 per cent of incident radiation reached the eye even when the lenses were covered with black opaque tape. The amount of exposure was increased substantially when the spectacles were moved 0.6 cm away from the forehead. The results show that the protection against ultraviolet exposure provided by prescription eyewear is highly variable and depends largely on its composition, size, and wearing position. PMID:3752323

Sherr, A E

1980-02-01

A review is presented of recent significant developments in industrial protective eyewear. Many of these developments apply to everyday practice. The new plastic protective, prescription, and plano lenses are discussed, and their merits presented. Needs for protection in the ultraviolet and near-infrared portions of the electromagnetic spectrum are described. It is shown that such spectral protection is now available in plastic lenses, but care must be taken to insure that the plastic has the required ultraviolet and near-infrared absorption. Eye protection standards have been improved. Specific changes in the standards are discussed.

Effectiveness of audiovisual distraction eyewear and computerized delivery of anesthesia during pulp therapy of primary molars in phobic child patients.

Fakhruddin, Kausar Sadia; El Batawi, Hisham; Gorduysus, Mehmet Omer

2015-01-01

The aim of this study is to assess the effectiveness of audiovisual distraction technique with video eyewear and computerized delivery system-intrasulcular (CDS-IS) during the application of local anesthetic in phobic pediatric patients undergoing pulp therapy of primary molars. This randomized, crossover clinical study includes 60 children, aged between 4 and 7-year-old (31 boys and 29 girls). Children were randomly distributed equally into two groups as A and B. This study involved two treatment sessions of pulp therapy, 1-week apart. During treatment session I, group A had an audiovisual distraction with video eyewear, whereas group B had audiovisual distraction using projector display only without video eyewear. During treatment session II, group A had undergone pulp therapy without video eyewear distraction, whereas group B had the pulp treatment using video eyewear distraction. Each session involved the pulp therapy of equivalent teeth in the opposite sides of the mouth. At each visit scores on the Modified Child Dental Anxiety Scale (MCDAS) (f) were used to evaluate the level of anxiety before treatment. After the procedure, children were instructed to rate their pain during treatment on the Wong Bakers' faces pain scale. Changes in pulse oximeter and heart rate were recorded in every 10 min. From preoperative treatment session I (with video eyewear) to preoperative treatment session II (without video eyewear) for the MCDAS (f), a significant (P > 0.03) change in the mean anxiety score was observed for group A. Self-reported mean pain score decreases dramatically after treatment sessions' with video eyewear for both groups. The use of audiovisual distraction with video eyewear and the use of CDS-IS system for anesthetic delivery was demonstrated to be effective in improving children's cooperation, than routine psychological interventions and is, therefore, highly recommended as an effective behavior management technique for long invasive procedures of pulp therapy in young children.

Laser safety eyewear.

PubMed

1993-04-01

In spite of repeated warnings about laser safety practices, as well as the availability of laser safety eyewear (LSE), eye injuries continue to occur during use of surgical lasers, as discussed in the Clinical Perspective, "Laser Energy and Its Dangers to Eyes," preceding this Evaluation. We evaluated 48 models of LSE, including goggles, spectacles, and wraps, from 11 manufacturers. The evaluated models are designed with absorptive lenses that provide protection from CO2 (carbon dioxide), Nd:YAG (neodymium:yttrium-aluminum-garnet), and 532 (frequency-doubled Nd:YAG) surgical laser wavelengths; several models provide multiwavelength protection. (Refer to ECRI's Product Comparison System report on LSE for specifications of other models.) Although most of the evaluated models can adequately protect users from laser energy--provided that the eyewear is used--many models of LSE, especially goggles, are designed with little regard for the needs of actual use (e.g., adequate labeling, no alteration of color perception, sufficient field of vision [FOV], comfort). Because these factors can discourage people from using LSE, we encourage manufacturers to develop new and improved models that will be worn. We based our ratings primarily on the laser protection provided by the optical density (OD) of the lenses; we acknowledge the contribution of Montana Laser Optics Inc., of Bozeman, Montana, in performing our OD testing. We also considered actual-use factors, such as those mentioned above, to be significant. Among the models rated Acceptable is one whose labeled OD is lower than the level we determined to be adequate for use during most laser surgery; however, this model offers protection under specific conditions of use (e.g., for use by spectators some distance from the surgical site, for use during endoscopic procedures) that should be determined by the laser safety officer (LSO). LSE that would put the wearer at risk are rated Unacceptable (e.g., some models are not properly or clearly labeled, have measured ODs that are not adequate for protection, or significantly restrict the wearer's FOV); also, LSE with side shields that do not offer adequate protection from diffuse laser energy are rated Unacceptable. Those models that offer adequate protection for surgical applications, but whose measured OD is less than their labeled OD, are rated Acceptable--Not Recommended; if the discrepancy is great, they are rated Unacceptable. Those models whose labels were removed during cleaning are rated Conditionally Acceptable.(ABSTRACT TRUNCATED AT 400 WORDS)

A tribute to Dr. Robert C. Allen, an inspirational teacher, humanitarian, and friend (Nov. 18, 1950-Mar. 24, 2005).

Dr. Robert C. Allen was a gifted educator, as well as experienced ophthalmologist, who was a close personal friend of Dr. Edlich at the University of Virginia Health System. While serving on the faculty at the University of Virginia Health System, Dr. Allen proved to be a compassionate physician, who developed close personal relationships with the residents, faculty, and his patients. Dr. Allen was invited by Dr Edlich to be a member of the Editorial Board of the Journal of Long-Term Effects of Medical Implants. When Dr. Allen told Dr. Edlich that he had ocular melanoma in 2000, this news was a wake-up call to Dr. Edlich on the need to prevent skin cancer, as well as ocular melanoma. Empowered by this news, Dr. Edlich was honored to co-author four articles on skin cancer prevention, as well as the latest article focusing on prevention of ocular melanoma. The Ocular Melanoma Foundation (Richmond, VA (USA)) was founded in 2003 by Dr. Robert C. Allen to increase awareness, enhance education, and provide advocacy among both patients and health care professionals regarding this rare, but potentially lethal cancer. It has a website that provides patient information, up-to-date information and enables communication/ discourse between and among patients and practitioners (admin@ocularmelanoma.org). Dr. Allen died on March 24, 2005, at his home surrounded by family and loved ones. When surgeons are faced with challenging healthcare diseases, Dr. Edlich's mentor, Dr. Owen Wangensteen, advised Dr. Edlich that he should seek the advice and guidance of skilled basic scientists, who are familiar with the problem. Dr. Wangensteen is recognized as the greatest surgical teacher during the 20th century. Consequently, Dr. Edlich enlisted the advice and guidance from the two co-authors of the next article regarding the scientific basis for the selection of sunglasses to prevent the development of cataracts, pterygia, skin cancer, as well as ocular melanoma. Dr. Reichow is a Professor of Optometry at Pacific University College of Optometry (Forest Grove, OR (USA)). Dr. Citek is Associate Professor of Optometry at Pacific University College of Optometry (Forest Grove (USA)). In their comprehensive evaluation of sunglasses, they found some disturbing results. Despite being endorsed by The Skin Cancer Foundation, the Walgreens eyewear samples offer only partial protection to the potential hazards of sunlight exposure. Those individuals who spend considerable time outdoors should seek sun filter eyewear with impact resistant polycarbonate lenses that provide 100% ultraviolet filtration, high levels of blue light filtration, and full visual field lens/frame coverage as provided by high wrap eyewear. There are several brands that offer products with such protective characteristics. Performance sun eyewear by Nike Vision (Nike Inc., Portland OR [USA]), available in both corrective and plano (nonprescription) forms, is one such brand incorporating these protective features, as well as patented optical and tint designs. Numerous Nike styles offer interchangeable lens options to meet the changing environmental conditions encountered outdoors. These technologies are incorporated into performance-driven frame designs inspired by feedback from some of the world's best athletes. Nonprescription Nike eyewear are available on-line at http://www.nike.com/nikevision, as well as at various well-known retail outlets. Nonprescription and prescription Nike eyewear are also available at the offices of many eye care professionals. Even though our latest report did not include soft contact lens, it is important to emphasize that Dr. Reichow and Dr. Citek have played a leadership role in coordinating the development of the Nike MAXSIGHT, an innovative fully tinted soft contact lens. This contact lens provides distortion-free optics, whether or not you wear prescription contacts. They filter out more than 90% of harmful blue light and 95% of UVA and UVB. For the contact lens, you should go to the website for more information http://www.nike.com/nikevision/content.html. The website has a list of practitioners who can service the patients with the respective sunglasses. With their exciting technologic advances in sunglass products, as well as tinted soft contact lens, the authors would encourage Nike Vision to develop an expanded international marketing program that allows all individuals in the world to easily purchase its products.

To evaluate the suitablity of commercially available moisture retention eyewear for treating evaporative dry eye. Eleven patients with evaporative dry eyes were prescibed moisture retention eyewear for 3 months in addition to regular lubricant eye drops. Frequency and severity of dry eye symptoms, corneal fluorescein staining and tear break up time (TBUT) were evaluated at baseline and 3-month post-treatment. Main outcome measure was global symptom score (based on severity and frequency of dry eye symptoms on a visual analog scale) and secondary outcomes were changes in sectoral corneal fluorescein staining and tear break up time (TBUT) from pre-treatment level. There was a significant improvement in dry eye symptoms after using moisture retention eyewear for 3 months (p < 0.05). Corneal fluorescein staining in all five zones of the cornea in both eyes improved significantly (p < 0.05). There was no significant improvement in TBUT. Patients used ocular lubricants less frequently (p < 0.05) compared to the commencement of the study. Patients found moisture retention eyewear to be useful in relieving dry eye symptoms in windy, air-conditioned environments or when doing vision-related daily tasks. This study shows that moisture retention eyewear might be a valuable adjunct in management of evaporative dry eye and this new design of commercially available eyewear could have a good acceptability rate.

Laser eye protection bleaching with femtosecond exposure

2003-06-01

The measured optical density of various laser eye protection samples is presented as a function of irradiance using femtosecond laser pulses. We show that the protective quality of some eyewear degrades as irradiance increases. In previous studies this problem has been demonstrated for samples irradiated by nanosecond pulses, but the current study shows that some modern laser eye protection seems to be robust except for the irradiance level possible with ultrashort laser pulse exposure. We discuss the most likely saturation mechanisms in this pulse duration regime and its relevance to laser safety.

This study aims to represent the epidemiologies, findings, treatments, use of resources, outcomes and protective-eyewear-use recommendations in sports-related eye injuries by sport type. The study population is comprised of all new eye injury patients in 1 year in Helsinki University Eye Hospital. Data were collected from patient questionnaires and hospital records. The follow-up period was 3 months. 149/1151 (12.9%) of eye injuries were sports-related. Thirty two percent were related to floorball (type of hockey played on a mat with a stick and a ball); football, tennis and ice hockey were the next most common eye-injury-causing sports. Relatively, the most dangerous sports were rink bandy, (bandy played on ice hockey rink with a stick and a ball) (0.50 injuries in 12 months/1000 participants, CI 0.10-1.46), floorball (0.47, CI 0.34-0.62) and tennis (0.47, CI 0.26-0.77). Contusion was the primary diagnosis in 77% of cases; 41% of contusion patients had severe, mainly retinal findings. The number of outpatient visits was 459; inpatient days 25 and major surgeries 31. One hundred and eight patients were estimated to need life-long follow-up. Seventeen patients had a permanent functional impairment, 4 in ice hockey, 3 in floorball, 2 each in tennis and badminton. Compared to a previous study, ice hockey eye injuries are increasing and relatively severe, and a third of these injuries occurred despite visor use. Floorball eye injury incidence has significantly declined, mainly due to recently enforced mandatory protective eyewear for younger age groups. Based on these findings, we recommend, in floorball, that protective eyewear should be mandatory in all age groups. Universally in ice hockey, the proper use of a visor should be emphasised. © 2015 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Radiation protection in interventional radiology: survey results of attitudes and use.

2013-10-01

To assess attitudes of interventional radiologists toward personal radiation protection and the use of radiation protection devices. Invitations to an anonymous online survey that comprised eight questions focused on operator attitudes toward radiation protection devices were sent via e-mail to the active membership of the Society of Interventional Radiology (SIR): a total of 3,158 e-mail invitations. A single reminder e-mail was sent. There were 504 survey responders (16% response rate). Reported radiation safety device use included lead apron (99%), thyroid shield (94%), leaded eyeglasses (54%), ceiling-suspended leaded shield (44%), rolling leaded shields (12%), ceiling-suspended/rolling lead-equivalent apron (4%), radiation-attenuating sterile surgical gloves (1%), and sterile lead-equivalent patient-mounted drape (4%). Reasons commonly cited for not using certain devices were comfort (eyewear), ease of use (mounted shields), and lack of availability (rolling/hanging shields and patient-mounted shields). Interventionalists have an array of tools from which to choose for personal radiation protection; however, for a variety of reasons related to lack of availability or choice, these tools are not universally employed. Further study may be of value to clarify why comfort was cited most often as the primary barrier to the use of protective eyewear and difficulty of use was cited as the primary barrier to use of mounted shields (despite reporting that concern for radiation-induced injury to the eye is paramount). It may also be of interest to further study why certain devices with demonstrable protection effects are not readily available, such as rolling/hanging and patient-mounted shields. © SIR, 2013.

Factors influencing worker use of personal protective eyewear.

Lombardi, David A; Verma, Santosh K; Brennan, Melanye J; Perry, Melissa J

2009-07-01

To identify and describe the array of factors that influence a workers' decision to wear personal protective eyewear (PPE) and the barriers that exist in preventing their use. A series of focus groups enrolled workers and supervisors primarily from manufacturing, construction, or service/retail industries that had potential exposure to eye injury hazards in their job tasks. Focus group sessions were facilitated to collect qualitative and quantitative data in two categories, "sought information" and "emergent themes", related to the factors influencing use of PPE. We conducted a series of 7 groups with 51 participants, 36 (71%) males and 15 (29%) females ranging in age from 19 to 64 years old, from a variety of occupations including construction (24%), production (22%), installation, repair and maintenance (14%), and healthcare (10%). Most were highly experienced in their occupation (>10 years); males (86%) and females (53%), and had received some safety training in the past (82%). The majority of workers in this study were required to wear PPE on their worksite (78%), however only 55% had a dedicated safety officer. A conceptual model that summarizes the "sought information" and "emergent themes" is presented that depicts the decision making process for the factors influencing use of PPE and consists of three primary branches; perceptions of hazards and risks, "barriers" to PPE usage, and enforcement and reinforcement. Lack of comfort/fit, and fogging and scratching of the eyewear were suggested as the most important barriers to PPE usage. Younger age and lack of safety training were other important factors affecting use of PPE. Several potentially modifiable factors identified would lead to an increase in workers' PPE use and encourage supervisors to provide ongoing positive feedback on the continuous use of PPE by workers at risk for an eye injury.

Crane, Elliot S; Kolomeyer, Anton M; Kim, Eliott; Chu, David S

2016-07-01

The authors aimed to analyze the causes and outcomes of golf-related ocular injuries in this retrospective meta-analysis, literature review, and original case series. Forty-one articles identified by PubMed search resulted in 11 included studies yielding 102 subjects. Included articles described all ocular golf injuries that presented to an institution during a determined period. Eight factors were analyzed: age, sex, location and mechanism of injury, protective eyewear use, resulting open-globe injury, resulting enucleation, and visual acuity changes. No subjects wore adequate protective eyewear. Significantly more subjects were injured by golf balls (72%) than golf clubs (27%) or foreign body (1%) (P < 0.0001). The ratio of golf ball to club injuries was significantly higher in adults (92%) than in children (23%) (P < 0.0001). Forty-seven of 93 (51%) injuries resulted in an open globe, whereas 27/82 (33%) injuries resulted in enucleation. The mean ± SD logMAR visual acuity improved by -0.641 ± 0.745 after treatment (>6 lines of improvement; P = 0.0001). Reported ocular golf injuries occur less frequently than other ocular sports injuries, but may result in devastating outcomes. Supervision of children using golf equipment should be encouraged.

Compliance With Protective Lens Wear in Anophthalmic Patients.

PubMed

Neimkin, Michael G; Custer, Philip L

To evaluate the frequency of protective lens wear by anophthalmic patients and identify factors that influence compliance. An IRB approved descriptive retrospective chart review of patients undergoing surgery with the senior author (PLC) with an anophthalmic orbit and one remaining sighted eye. Results were tabulated and analyzed using age, indication for procedure, duration of visual symptoms, safety glasses wear, number of postoperative visits, and evidence of new trauma to the remaining eye. All patients underwent counseling on the importance of protective lens wear preoperatively and each subsequent visit. Etiologies for loss of the eye in the 132 study patients included trauma (33.3%), blind painful eye (33.3%), congenital disorders (14.4%), adult-onset malignancy (14.4%), and retinoblastoma (4.5%). At the final visit, protective lenses were worn in the following patterns: full-time (55.3%), frequently (11.4%), occasional (6%), and never (28.8%). The regular use of protective eyewear at last visit was more common in patients wearing glasses at presentation (79.7%), than in those who did not (32.9%; p ≤ 0.001). Increased number of office encounters correlated with more frequent use of protective eyewear (p ≤ 0.01). Patient age (p = 0.95), indication for surgery (p = 0.97), and duration of visual loss (p = 0.85) were not predictive of safety glasses wear. Three patients had evidence of subsequent ocular trauma to the remaining eye, with 2 having resultant decrease in acuity; none of these 3 patients wore safety glasses full-time. A significant number of anopthalmic patients were not wearing protective lenses at presentation. Overall compliance was poor; but repeated education on the importance of safety glasses appears to improve compliance. Educating referring providers and primary care physicians about the importance of early and repeated counseling is vital to increasing compliance.

Skin cancer prevention remains a national priority. Reducing chronic UV radiation exposure for outdoor workers through sun-safety practices is an important step to help reduce the incidence of skin cancer. To determine the presence of occupational sun-safety policies at local government organizations in a single state. Of 571 potentially eligible local government organizations of Colorado cities, counties, and special tax districts, we enrolled 98 in a randomized pretest-posttest controlled experiment starting August 15, 2010, that evaluated an intervention to promote the adoption of sun-safety policies. We used a policy-coding protocol to evaluate personal sun-protection practices, environmental and administrative controls, and policy directives for sun safety starting February 10, 2011. We report the baseline assessment of the occupational sun-protection policies of these organizations. The presence of an occupational sun-safety policy. Overall, 85 local government organizations (87%) had policies that required personal sun-protection practices, including the use of eyewear, hats, and protective clothing. However, of the 98 responding organizations, only 8 hat policies (8%), 10 eyewear policies (10%), and 7 clothing policies (7%) mentioned sun protection as the intent of the policy. Only cosmopoliteness, operationalized as proximity to an urban area, was associated with the presence of a sun-safety policy (odds ratio, 0.99 [95% CI, 0.98-1.00]; P = .02). Outdoor workers are at increased risk for skin cancer because of long-term exposure to solar UV radiation. Although organizational policies have the potential to increase sun protection in occupational settings, occupational sun-safety policies were uncommon among local governments. Opportunities exist for dermatologists and other physicians to influence occupational sun-safety practices and policies, which are consistent with other safety procedures and could easily be integrated into existing workplace practices.

Editorial: ERCP-Related Radiation Cataractogenesis: Is It Time to Be Concerned?

2017-05-01

With the growing number of fluoroscopic guided endoscopic procedures, radiation-related risk needs to be further assessed. Recent evidence indicates that radiation cataractogenesis occurs at a lower dose threshold than previously believed. While body aprons and thyroid shields are well-established standard protection during fluoroscopy, ocular safety and the use of protective eyewear are not as well defined. This prospective study answered two important questions: Does the standard body dosimeter provide an accurate ocular dosimetry? And what is the time of fluoroscopy needed to warrant using lens protection? It also raises the question whether current guidelines need to be updated.

This study was designed to evaluate the reduction of the eye lens dose when wearing protective eyewear in interventional radiology and to identify conditions that optimize the efficacy of radiation safety glasses. The dose reduction provided by different models of radiation safety glasses was measured on an anthropomorphic phantom head. The influence of the orientation of the phantom head on the dose reduction was studied in detail. The dose reduction in interventional radiological practice was assessed by dose measurements on radiologists wearing either leaded or no glasses or using a ceiling suspended screen. The different models of radiation safety glasses provided a dose reduction in the range of a factor of 7.9-10.0 for frontal exposure of the phantom. The dose reduction was strongly reduced when the head is turned to the side relative to the irradiated volume. The eye closest to the tube was better protected due to side shielding and eyewear curvature. In clinical practice, the mean dose reduction was a factor of 2.1. Using a ceiling suspended lead glass shield resulted in a mean dose reduction of a factor of 5.7. The efficacy of radiation protection glasses depends on the orientation of the operator's head relative to the irradiated volume. Glasses can offer good protection to the eye under clinically relevant conditions. However, the performance in clinical practice in our study was lower than expected. This is likely related to nonoptimized room geometry and training of the staff as well as measurement methodology.

Implementing AORN Recommended Practices for Laser Safety.

Castelluccio, Donna

2012-05-01

Lasers used in the OR pose many risks to both patients and personnel. AORN's "Recommended practices for laser safety in perioperative practice settings" identifies the potential hazards associated with laser use, such as eye damage and fire- and smoke-related injuries. The practice recommendations are intended to be used as a guide for establishing best practices in the workplace and to give perioperative nurses strategies for implementing the recommended safety measures. A laser safety program should include measures to control access to laser use areas; protect staff members and patients from exposure to the laser beam; provide staff members and patients with the appropriate safety eyewear for use in the laser use area; and protect staff members and patients from surgical smoke, electrical, and fire hazards. Measures such as using a safety checklist or creating a laser cart can help perioperative nurses successfully incorporate the practice recommendations. Patient scenarios are included as examples of how to use the document in real-life situations. Copyright © 2012 AORN, Inc. Published by Elsevier Inc. All rights reserved.

New method for evaluating high-quality fog protective coatings

NASA Astrophysics Data System (ADS)

Czeremuszkin, Grzegorz; Latreche, Mohamed; Mendoza-Suarez, Guillermo

2011-05-01

Fogging is commonly observed when humid-warm air contacts the cold surface of a transparent substrate, i.e. eyewear lenses, making the observed image blurred and hazy. To protect from fogging, the lens inner surfaces are protected with Anti-Fog coatings, which render them hydrophilic and induce water vapor condensation as a smooth, thin and invisible film, which uniformly flows down on the lens as the condensation progresses. Coatings differ in protection level, aging kinetics, and susceptibility to contamination. Some perform acceptably in limited conditions, beyond which the condensing water film becomes unstable, nonuniform, and scatters light or shows refractory distortions, both affecting the observed image. Quantifying the performance of Anti-Fog coated lenses is difficult: they may not show classical fogging and the existing testing methods, based on fog detection, are therefore inapplicable. The presented method for evaluating and quantifying AF properties is based on characterizing light scattering on lenses exposed to controlled humidity and temperature. Changes in intensity of laser light scattered at low angles (1, 2 4 and 8 degrees), observed during condensation of water on lenses, provide information on the swelling of Anti-Fog coatings, formation of uniform water film, going from an unstable to a steady state, and on the coalescence of discontinuous films. Real time observations/measurements allow for better understanding of factors controlling fogging and fog preventing phenomena. The method is especially useful in the development of new coatings for military-, sport-, and industrial protective eyewear as well as for medical and automotive applications. It allows for differentiating between coatings showing acceptable, good, and excellent performance.

Background: Workers in the sawmilling industry are at risk of various ocular hazards as a direct result of the sawmilling processes. The aim of this study was to determine the pattern of conjunctival disorders between technical and administrative sawmill workers in Benin, Nigeria. Methods: A cross-sectional study was performed on sawmill workers in Benin, Nigeria, between January and May 2009, with the aid of pre-tested questionnaires. Ocular examination was performed on all subjects. Data obtained were recorded and analysed using SPSS version 13. Results: A total of 553 sawmill workers were studied, among whom 449 (81.2%) and 104 (18.8%) were technical and administrative workers, respectively. There were 496 (89.7%) males and 57 (10.3%) females. The age range was 15–80 years, with a mean of 38.9 years (SD 12.8). Pingueculum was found in 127 (23%) workers, among whom 122 (27.2%) were technical workers and 5 (4.8%) were administrative workers. Pterygium was present in 65 (11.8%) workers, among whom 64 (14.3%) were technical workers and 1 (1%) was an administrative worker. Seven (1.6%) technical workers used protective eyewear; 2 (0.4%) wore this protective eyewear regularly. Conclusion: Technical sawmill workers are at risk of developing conjunctival disorders, which result from chronic ocular irritation. This can be prevented by the provision of protective eye devices in the workplace. PMID:22135600

Theoretical model for design and analysis of protectional eyewear.

PubMed

Zelzer, B; Speck, A; Langenbucher, A; Eppig, T

2013-05-01

Protectional eyewear has to fulfill both mechanical and optical stress tests. To pass those optical tests the surfaces of safety spectacles have to be optimized to minimize optical aberrations. Starting with the surface data of three measured safety spectacles, a theoretical spectacle model (four spherical surfaces) is recalculated first and then optimized while keeping the front surface unchanged. Next to spherical power, astigmatic power and prism imbalance we used the wavefront error (five different viewing directions) to simulate the optical performance and to optimize the safety spectacle geometries. All surfaces were spherical (maximum global deviation 'peak-to-valley' between the measured surface and the best-fit sphere: 0.132mm). Except the spherical power of the model Axcont (-0.07m(-1)) all simulated optical performance before optimization was better than the limits defined by standards. The optimization reduced the wavefront error by 1% to 0.150 λ (Windor/Infield), by 63% to 0.194 λ (Axcont/Bolle) and by 55% to 0.199 λ (2720/3M) without dropping below the measured thickness. The simulated optical performance of spectacle designs could be improved when using a smart optimization. A good optical design counteracts degradation by parameter variation throughout the manufacturing process. Copyright © 2013. Published by Elsevier GmbH.

Foley, E S

1994-01-01

Many changes have occurred in the clinical appearance of dental hygienists in the past few years because of increased emphasis on infection control and disease prevention. The purpose of this study was to assess dental hygiene program clinical attire requirements in 1993 and to compare them with requirements as described by a 1988 survey. Checklist questionnaires were mailed to the directors of all 211 dental hygiene programs in the United States and Puerto Rico in October 1993. Questions were asked regarding clinical attire requirements for students and faculty, including uniforms, gowns, lab coats, masks, protective eyewear, shoes, hair coverings, laundry management, and changes under consideration. Percentages were calculated by region and for all responding programs. Of 211 questionnaires mailed, 178 were returned, for a response rate of 84%. Results indicated that students and faculty are currently wearing more colorful uniforms and scrubs than in 1988. Long-sleeved lab coats, disposable gowns, and washable surgical gowns are increasing in use. Glasses and face masks were required for all students and faculty in both surveys, but chin-length face shields are increasing in use as optional face protection. In most instances, face shields are worn with face masks. Laundry services are being provided for faculty (employees); however, most students continue to be responsible for their own laundry after being instructed to follow stringent guidelines taught by the faculty. Increasing emphasis on personal and patient protection is moving clinical attire requirements toward a more surgical appearance. Dental hygiene educators continue to monitor and to stay current with federal infection control recommendations, regulations, and guidelines.

The eye occupies 0.1% of the total body surface yet it accounts for 8-13% of battle injuries in modern warfare worldwide. Protective eyewear can prevent over 90% of these eye injuries in both military and civilian settings. This study presents an analysis of a military casualty database and describes the proportion and distribution of eye injuries among Israel Defense Force (IDF) Soldiers. All trauma patients recorded in the IDF Trauma Registry (ITR) in whom ocular injury related to combat or to training was documented were reviewed. There were 129 patients with documented eye injury sustained during combat or training between 1997 and 2013: 75% of injuries were related to combat and the remainder occurred during training. Penetrating fragmental injuries accounted for 74% of combat related injuries and 28% of training related injuries. Sixty-six percent (66%) of these casualties were subsequently re-classified as no longer fit for combat duties. Combat related injuries resulted in a higher incidence of severe injuries compared to training related injuries (P<0.05). Despite optimal medical care, the majority of soldiers who sustain eye injuries during military service suffer from substantial disability and most are no longer fit for combat service. A majority are discharged from military service. Protective eyewear could potentially prevent penetrating fragmental wounds which are the most common cause of injury. Further research on optimal orbital protection is critical for both the military and the civilian sectors. Copyright © 2015 Elsevier Ltd. All rights reserved.

Purpose To evaluate the frequency of protective lens wear by anophthalmic patients and identify factors that influence compliance. Methods An IRB approved descriptive retrospective chart review of patients undergoing surgery with the senior author (PLC) with an anophthalmic orbit and one remaining sighted eye. Results were tabulated and analyzed using age, indication for procedure, duration of visual symptoms, safety glasses wear, number of post-operative visits, and evidence of new trauma to the remaining eye. All pateints underwent counseling on the importance of protective lens wear preoperatively and each subsequent visit. Results Etiologies for loss of the eye in the 132 study patients included trauma (33.3%), blind painful eye (33.3%), congenital disorders (14.4%), adult-onset malignancy (14.4%), and retinoblastoma (4.5%). At the final visit, protective lenses were worn in the following patterns: full-time (55.3%), frequently (11.4%), occasional (6%), and never (28.8%). The regular use of protective eyewear at last visit was more common in patients wearing glasses at presentation (79.7%), than in those who did not (32.9%) (p=<0.001). Increased number of office encounters correlated with more frequent use of protective eyewear (p=<0.01. Patient age (p=0.95), indication for surgery (p=0.97), and duration of visual loss (p=0.85) were not predictive of safety glasses wear. 3 patients had evidence of subsequent ocular trauma to the remaining eye, with 2 having resultant decrease in acuity; none of these 3 patients wore safety glasses full-time. Conclusions A significant number of anopthalmic patients were not wearing protective lenses at presentation. Overall compliance was poor; but repeated education on the importance of safety glasses appears to improve compliance. Educating referring providers and primary care physicians about the importance of early and repeated counseling is vital to increasing compliance. PMID:26866334

IMPORTANCE Skin cancer prevention remains a national priority. Reducing chronic UV radiation exposure for outdoor workers through sun-safety practices is an important step to help reduce the incidence of skin cancer. OBJECTIVE To determine the presence of occupational sun-safety policies at local government organizations in a single state. DESIGN, SETTING, AND PARTICIPANTS Of 571 potentially eligible local government organizations of Colorado cities, counties, and special tax districts, we enrolled 98 in a randomized pretest-posttest controlled experiment starting August 15, 2010, that evaluated an intervention to promote the adoption of sun-safety policies. We used a policy-coding protocol to evaluate personal sun-protection practices, environmental and administrative controls, and policy directives for sun safety starting February 10, 2011. We report the baseline assessment of the occupational sun-protection policies of these organizations. MAIN OUTCOMES AND MEASURES The presence of an occupational sun-safety policy. RESULTS Overall, 85 local government organizations (87%) had policies that required personal sun-protection practices, including the use of eyewear, hats, and protective clothing. However, of the 98 responding organizations, only 8 hat policies (8%), 10 eyewear policies (10%), and 7 clothing policies (7%) mentioned sun protection as the intent of the policy. Only cosmopoliteness, operationalized as proximity to an urban area, was associated with the presence of a sun-safety policy (odds ratio, 0.99 [95% CI, 0.98–1.00]; P = .02). CONCLUSIONS AND RELEVANCE Outdoor workers are at increased risk for skin cancer because of long-term exposure to solar UV radiation. Although organizational policies have the potential to increase sun protection in occupational settings, occupational sun-safety policies were uncommon among local governments. Opportunities exist for dermatologists and other physicians to influence occupational sun-safety practices and policies, which are consistent with other safety procedures and could easily be integrated into existing workplace practices.

2000-01-01

Objectives—To determine the recent incidence of eye injury due to sport in Scotland, identify any trend, and establish which sports are responsible for most injury? The type of injury and final visual outcome is also evaluated. Methods—A prospective observational study of ocular injuries sustained during sport was performed over a one year period. Only patients requiring hospital admission were included. Data were collected on a standardised proforma and entered into a central database. Patients were followed up for at least three months. Results—Of 416 patients admitted because of ocular injury, 52 (12.5%) resulted from playing a sport. Although all racquet sports together accounted for 47.5% of these injuries, football was the single most common sport associated with ocular trauma, being responsible for 32.5% of cases. The most common clinical finding was macroscopic hyphaema occurring in 87.5% of patients. Overall the final visual acuity was 6/6 in 92.5% of patients. Conclusions—The incidence of eye injury due to sport at 12.5% is lower than previously reported, suggesting a change in the pattern of ocular trauma. Football is the single most common cause of ocular injury from sport in Scotland, but the wearing of protective headgear would be difficult to instigate. The incidence of hyphaema in sport related ocular trauma (87.5%) is almost double that of all ocular injury (47.8%), so the potential for serious visual loss as the result of a sports injury should not be underrated. Ophthalmologists have a role in protecting this young population at risk by actively encouraging the design and use of protective eyewear.

To determine the current eyecare behaviour of dentists and compare this against published standards concerning frequency of sight test intervals and eye protection. Four hundred dentists were selected at random for inclusion in the study from the UK 2004 Dentists Register. They were invited to complete a questionnaire that ascertained their gender and age, current eyesight status and method of correction, elapsed time interval since their last eyesight test and reason for attendance. In addition, the use and power of magnification was sought along with the adoption of protective eyewear. Responses were coded and placed in a relational database to facilitate interrogation and subsequent statistical analysis. The questionnaire return rate was 63% (247 and allowing for the seven questionnaires returned marked unknown at this address). Of these 158 were males and 81 female. The majority worked in general dental practice. Those with known eyesight deficiencies were statistically more likely (p < 0.01) to attend for routine eye examination. Sixteen percent of respondents failed to attend for routine eye examination at least every two years. The mean age of those who had detected a change in their eyesight and sought examination was 43.59 (SD = 10.57) for males and 39.07 years (SD = 9.41) for females. This mirrored closely the mean age when the use of magnification was adopted (males = 42.39 (10.30), females = 40.33 (10.55)). The use of magnification was not universally adopted. Eye protection compliance was a low as 57% when using laboratory cutting equipment. Although compliance with accepted recommendations for biannual eyesight testing was higher than that for the general population, not all dentists complied. The adoption of protective eyewear was patchy and exposed dentists to unnecessary risk.

Reflections from instruments in the surgical field involving the CO2 laser beam present a serious ocular hazard. In addition to the use of plastic or glass protective eyewear, this hazard can be minimized by utilizing anodized instruments and recognizing the specific distances at which various reflections are no longer hazardous depending upon certain variables, including laser output wattage, emergent beam lengths, and surface characteristics of the reflecting instruments.

TU-D-209-07: Monte Carlo Assessment of Dose to the Lens of the Eye of Radiologist Using Realistic Phantoms and Eyeglass Models

DOE Office of Scientific and Technical Information (OSTI.GOV)

Xu, X; Lin, H; Gao, Y

Purpose: To study how eyeglass design features and postures of the interventional radiologist affect the radiation dose to the lens of the eye. Methods: A mesh-based deformable phantom, consisting of an ultra-fine eye model, was used to simulate postures of a radiologist in fluoroscopically guided interventional procedure (facing the patient, 45 degree to the left, and 45 degree to the right). Various eyewear design features were studied, including the shape, lead-equivalent thickness, and separation from the face. The MCNPX Monte Carlo code was used to simulate the X-ray source used for the transcatheter arterial chemoembolization procedure (The X-ray tube ismore » located 35 cm from the ground, emitting X-rays toward to the ceiling; Field size is 40cm X 40cm; X-ray tube voltage is 90 kVp). Experiments were also performed using dosimeter placed on a physical phantom behind eyeglasses. Results: Without protective eyewear, the radiologist’s eye lens can receive an annual dose equivalent of about 80 mSv. When wearing a pair of lead eyeglasses with lead-equivalent of 0.5-mm Pb, the annual dose equivalent of the eye lens is reduced to 31.47 mSv, but both exceed the new ICRP limit of 20 mSv. A face shield with a lead-equivalent of 0.125-mm Pb in the shape of a semi-cylinder (13cm in radius and 20-cm in height) would further reduce the exposure to the lens of the eye. Examination of postures and eyeglass features reveal surprising information, including that the glass-to-eye separation also plays an important role in the dose to the eye lens from scattered X-ray from underneath and the side. Results are in general agreement with measurements. Conclusion: There is an urgent need to further understand the relationship between the radiation environment and the radiologist’s eyewear and posture in order to provide necessary protection to the interventional radiologists under newly reduced dose limits.« less

2012-01-01

The purpose of this pilot study was to evaluate the effect of magnification lenses on the indirect vision skills of dental hygiene students. This pilot study examined the accuracy and efficiency of dental hygiene students' indirect vision skills while using traditional safety lenses and magnification lenses. The sample was comprised of 14 students in their final semester of a dental hygiene program. A crossover study approach was utilized, with each participant randomly assigned to a specific order of eyewear. The study included evaluation of each participant taking part in 2 separate clinical sessions. During the first session, each participant completed a clinical exercise on a dental manikin marked with 15 dots throughout the oral cavity while wearing the randomly as signed eyewear, and then completed a similar exercise on a differently marked dental manikin while wearing the randomly assigned eyewear. This procedure was repeated at a second clinical session, however, the dental manikin and eyewear pairings were reversed. Accuracy was measured on the number of correctly identified dots and efficiency was measured by the time it took to identify the dots. Perceptions of the participants' use of magnification lenses and the participants' opinion of the use of magnification lenses in a dental hygiene curriculum were evaluated using a questionnaire. Comparing the mean of the efficiency scores, students are more efficient at identifying indirect vision points with the use of magnification lenses (3 minutes, 36 seconds) than with traditional safety lenses (3 minutes, 56 seconds). Comparing the measurement of accuracy, students are more accurate at identifying indirect vision points with traditional safety lenses (84%) as com pared to magnification lenses (79%). Overall, the students report ed an increased quality of dental hygiene treatment provided in the clinical setting and an improved clinical posture while treating patients with the use of magnification lenses. This study did not produce statistically significant data to support the use of magnification lenses to enhance indirect vision skills among dental hygiene students, however, students perceived that their indirect vision skills were enhanced by the use of magnification lenses.

The fate of eyewear in aircraft ejections.

O'Connell, S R; Markovits, A S

1995-02-01

Ejection from jet aircraft has been exhaustively studied from many perspectives; e.g., causes of ejection, types and causes of ejection injuries, etc. Curiously, no reports exist describing the fate of eyewear in ejections. Many pilots wear required corrective lenses during flight operations, and many wear tinted lenses. What happens to these during ejection? What injuries are a result of the eyewear? What factors can be identified that influence retention of the eyewear and severity of related injury? Do contact lenses provide significant advantages? There were 48 ejections occurring between 1977 and 1990 that involved corrective or tinted lens use that were retrospectively examined using Naval Safety Center records and personal questionnaires. There were five contact lens wearers included. Retention rates were calculated as functions of several variables. Although 37 of 46 lost all lenses, each instance of retention occurred with visor down, oxygen mask on, helmet properly secured, and at lower ejection speeds. Related injuries were minor and occurred in only 20%. The utility and need for enforcement of standard operating procedures (i.e., mask on, helmet secured, and visor down) was clearly demonstrated. Only 19 of 46 clearly met all 3 criteria. Contact lens users were too few to allow meaningful conclusions.

Prescription safety eyewear: impact studies of lens and frame failure.

PubMed

Vinger, P F; Woods, T A

2000-02-01

To determine if a plano lens could be the test lens for all prescription (Rx) lenses and to investigate why Rx lenses pop out of safety eyewear. Plano and Rx polycarbonate lenses (n = 641) with varying thickness and edge geometry, mounted on steel lens holders, and Rx safety eyewear (n = 128) placed on headforms were impacted with test objects of varying diameter and hardness. Impacts were studied with 500 to 2,000 frames-per-second motion analysis. Plano lenses were at least, or more, prone to failure (dislodgment, perforation, shatter, or crack) than -3.00 or +3.00 lenses of the same minimum thickness. More than 40% of safety frames with removable lenses broke or had lenses pop out when impacted with energies expected in industry and sports. Plano lenses can be used as the test lenses for all Rx lenses made of the same material with the same minimal thickness. The ANSI Z87.1-1989 industrial standard for Rx eyewear is inadequate for sports or other activities with high-impact potential. The best lens-retention system has, as a component, a frame with a bevel perpendicular to a frontal impact force.

To investigate the epidemiology of eye injuries sustained by professional basketball players in the National Basketball Association (NBA). A prospective study involving all NBA athletes who sustained eye injuries between February 1, 1992, and June 20, 1993, was conducted. Twenty-seven NBA team athletic trainers, physicians, and ophthalmologists were provided data forms to complete for any player examined for an eye injury. Practice and game exposures during the preseason, regular season, playoffs, and championships were included. Of the 1092 injuries sustained by NBA players during the 17-month period, 59 (5.4%) involved the eye and adnexa. Eighteen (30.5%) of the injuries occurred while the player was in the act of rebounding, and 16 (27.1%) while the player was on offense. The most common diagnoses included 30 abrasions or lacerations to the eyelid (50.9%), 17 contusions (edema and/or ecchymosis) to the eyelid or periorbital region (28.8%), and seven corneal abrasions (11.9%). There were three orbital fractures (5.1%). Most injuries were caused by fingers (35.6%) or elbows (28.8%). Nine players (15.3%) missed subsequent games because of their injury. Fifty-seven players (96.6%) were not wearing protective eyewear at the time of injury. The incidence of eye injuries in NBA players during the 17-month period was 1.44 per 1000 game exposures. Frequent physical contact in professional basketball players leaves them at great risk for sustaining eye injuries. To prevent these injuries, protective eyewear is recommended.

An improved spectacle frame has been developed for use during periods of extreme physical activity, particularly by military personnel during combat operations, and which can be used under protective face masks and headgear. The frame has a wrap-around shape, made of nylon with a contoured, recessed bridge and safety lens groove. U-shaped bridles snap on the frame front and an adjustable, interlocking strap fits over the bridles and passes under a protective mask sealing area. Field tests were conducted with 1231 soldiers at 12 military installations. Over 90% of those tested found combat spectacles were comfortable to wear, extremely durable, compatible with headgear and superior to existing military eyewear.

The percentage of foreign employees involved in these accidents (19.5%) was almost the same as the proportion they represent of the total personnel. Accident rates were found to be lowest on Mondays and Wednesdays; peak accident times were in the late morning and early afternoon. Although there has been a considerable improvement in the availability of protective eyewear in recent years, it is still not worn often enough. In 60% of the eye accidents considered here protective goggles should have been worn.

1984-01-01

As the sales of surgical lasers continue to grow, the problem of laser safety in hospitals becomes increasingly more urgent. This article considers both the principles and the practice of laser safety, and indicates how safety codes should be organized within a hospital. Eye safety is of paramount importance, and the effects of different wavelengths of laser radiation on the eye are described, both for intrabeam and extended-source exposure. An account is given of the concept of Maximum Permissible Exposure (MPE) and how it depends upon wavelength and exposure duration. The standard laser classification is developed in relation to MPE. The use of laser protective eyewear is discussed for the surgeon, other theatre staff and the patient. Finally, the role of the Laser Protection Supervisor and of the Laser Protection Adviser are explained in the context of establishing a local laser safety code.

Individual Fit Testing of Hearing Protection Devices Based on Microphone in Real Ear.

Labeled noise reduction (NR) data presented by manufacturers are considered one of the main challenging issues for occupational experts in employing hearing protection devices (HPDs). This study aimed to determine the actual NR data of typical HPDs using the objective fit testing method with a microphone in real ear (MIRE) method. Five available commercially earmuff protectors were investigated in 30 workers exposed to reference noise source according to the standard method, ISO 11904-1. Personal attenuation rating (PAR) of the earmuffs was measured based on the MIRE method using a noise dosimeter (SVANTEK, model SV 102). The results showed that means of PAR of the earmuffs are from 49% to 86% of the nominal NR rating. The PAR values of earmuffs when a typical eyewear was worn differed statistically ( p < 0.05). It is revealed that a typical safety eyewear can reduce the mean of the PAR value by approximately 2.5 dB. The results also showed that measurements based on the MIRE method resulted in low variability. The variability in NR values between individuals, within individuals, and within earmuffs was not the statistically significant ( p > 0.05). This study could provide local individual fit data. Ergonomic aspects of the earmuffs and different levels of users experience and awareness can be considered the main factors affecting individual fitting compared with the laboratory condition for acquiring the labeled NR data. Based on the obtained fit testing results, the field application of MIRE can be employed for complementary studies in real workstations while workers perform their regular work duties.

The Partnership for Citrus Worker Health (PCWH) is a coalition that connects academic institutions, public health agencies, industry and community-based organizations for implementation of an eye safety pilot project with citrus workers using the Camp Health Aide (CHA) model. This project was an implementation evaluation of an eye safety curriculum using modeling and peer-to-peer education among Mexican migrant citrus workers in a southwest Florida community to increase positive perceptions toward the use of safety eyewear and reduce occupational eye injuries. CHAs have been employed and trained in eye safety and health during harvesting seasons since 2004. Field observations, focus group interviews, and written questionnaires assessed program implementation and initial outcomes. There was an increase in positive perceptions toward use of safety eyewear between 2004 and 2005. Evaluation of training suggested ways to improve the curriculum. The modest literacy level of the CHAs necessitated some redesign of the curriculum and its implementation (e.g., introduction of and more reliance on use of training posters). PCWH benefited by extensive documentation of the training and supervision, a pilot project that demonstrated the potential effectiveness of CHAs, and having a well-defined target population of citrus workers (n = 427). Future research can rigorously test the effectiveness of CHAs in reducing eye injuries among citrus workers.

The aims of this study were to investigate the levels of optical radiation exposure in glassblowing and to determine type(s) of protective eyewear commonly used. Radiometric measurements of radiant emissions from different molten glass materials and heating systems were carried out in six installations. Spectral transmittance curves of available protective lenses used at the locations were obtained. Significant variation (P = 0.0001) in ocular irradiation was obtained. All operations produced irradiances higher than the threshold limit values (TLVs) for the visible spectrum (400 to 700 nm). In craft glassblowing which employs furnace systems, irradiance levels exceeding the TLVs for near infrared (760 1o 1100 nm) were obtained. Molten soda-lime and quartz glasses emitted substantial subthreshold near UV radiation. This study shows that variation exists in glassblowing ocular radiation exposure due to different glass materials and heating systems, therefore selection of appropriate eye protector should be on an individual basis.

The use of lasers in medicine and especially surgery is rapidly expanding in many disciplines from clinical laboratory to the office practice and operating room. It is essential that users of this powerful tool have knowledge of their potential hazards and the measures to protect patients and personnel against injuries or undesired effects. Below, we have included information about the way lasers are classified; the development of protective standards; the current status of protection standards that apply to lasers, especially those used in medicine/surgery; the specific kinds of hazards associated with medical/surgical applications; and the measures by which hazards have been controlled. Since laser technology is still a young field, it is likely that problems unknown at present will occur and methodologies for controlling hazards will evolve. The American National Standards Committee produced the first consensus standard Z136.1 in 1973. The Standard was revised in 1976 to accommodate differences in biological effects for different wavelengths in the visible spectrum. The ANSI Standard has been revised again in 1980, and currently (1984) there are two additional standards in preparation, Z136.2 and 136.3, which treat the safe use of light-emitting diodes and the safe use of lasers in the health care environment, respectively. Most surgical and medical lasers are Class III or IV. Some lasers have a Class IV therapy level beam plus a Class I or II alignment beam. When using lasers, it is possible to generate incandescence or fluorescence in an irradiated object. This can occur even with protective eyewear, because the correlated radiations are usually of a different wavelength. Generally, this should not be a problem when beams are directed at biological material. However, hazard could be caused by lasers designed to produce fluorescence. Control of correlative radiation in a laser system is required in the federal regulations. Hazards of lasers may be grouped as those to the eye, skin and associated hazards, fire, x-rays, electrical, fumes, toxic materials, etc. Effects on tissue are governed by the following factors:--the energy or power density of the beam;--the absorption in tissue at the laser wavelength;--the time the beam is held at a given area.;--the protective effects of heat removal by thermal conduction and by circulation. Eye hazards include thermal burns or acoustical disruption (shock waves) from high-powered or high-energy beams in the visible and near infrared wavelengths. Direct beam exposure or specular or diffuse reflaction from these very high-power lasers can also cause injuries to other parts of the retina. For example, beams can directly penetrate through the sclera and cause retinal injury. Near ultraviolet (less than 400 hm) and far infrared (.3000 hm including CO2 lasers) can cause moderate to severe corneal burns. Far ultraviolet (200-315 nm), mid infrared (1400-3000 nanometers) can cause welders' flash or snow blindness and chronic exposure could cause cataract, and exposure to ultraviolet rays may be carcinogenic. For CO2 lasers, the far infrared radiation is attenuated by plastic goggles, or by glasses, or quartz. Other eyewear with special filters is used for different lasers. The whole personnel who may be exposed to direct beams, specular reflections, and many times diffuse reflections must wear protective eyewear. In all cases the surgeon and others viewing the procedure through the endoscope need glasses or suitable protective lenses installed in the endoscope. Persons who are not viewing the beam may not need to wear protective glasses with the same level of optical density. Glasses may be selected to provide protection for lasers operating in the visible wavelength to the point where the normal aversion response could protect the individual.

Determination of eye safety filter protection factors associated with retinal thermal hazard and blue light photochemical hazard for intense pulsed light sources.

An assessment is provided of protection factors afforded for retinal thermal hazard and blue light photochemical hazard for a range of filters used with intense pulsed light sources (IPLs). A characteristic IPL spectrum based on black body radiation at 5000 K with a low cut filter at 515 nm was identified as suitable for such estimations. Specific filters assessed included types with idealized transmission properties and also a range of types whose transmission characteristics were measured by means of a Bentham DMc150 spectroradiometer. Predicted behaviour based on these spectra is outlined which describes both the effectiveness of protection and the level of luminous transmittance afforded. The analysis showed it was possible to describe a figure of merit for a particular filter material relating the degree of protection provided and corresponding value of luminous transmittance. This consideration is important for providing users of IPL equipment with safety eyewear with adequate level of visual transmittance.

To determine the current population-based epidemiology, treatment, use of resources and outcomes of children's eye injuries in Finland. The study included all new patients, 16 years of age or under, with ocular or orbital traumas taken into care to the Helsinki University Eye Hospital (population base 1.5 million people) in 1 year. The follow-up period was 3 months. Two hundred and two children's eye injuries were treated. The eye injury incidence was 5.2-8.3 per 10 000 per year, including all minor and major eye traumas. Eye injury most likely occurred at the junior high school age (13-16 years). Thirty-three percentage of accidents took place at home and 24% at school or in day care. The most common causes were sports equipment (15%), contact with human body (12%) and superficial foreign bodies (11%). Excluding minor injuries, contusion was the most common diagnosis (n = 60, 30%). Eighty-seven percentage of contusion patients were estimated to need lifelong follow-up due to elevated glaucoma risk. Nine percentage of all patients had a permanent disability. Guns, fireworks, tools and pellet guns were relatively the most dangerous objects. Pellet guns caused 6% of eye injuries, 36% of them causing permanent impairment. The number of outpatient visits was altogether 443, inpatient days were 49, and 60 children had major surgeries. Use of protective eyewear would have prevented or diminished eye traumas caused by pellet gun, floorball, most of the firework and in many superficial foreign body. The use of pellet guns and protective eyewear should be more supervised. Fireworks and tools are not suitable toys for children. © 2016 Acta Ophthalmologica Scandinavica Foundation.

Badminton is a famous sport usually played without any protective eyewear. Ocular injury from one's own partner in a doubles game, with the shuttlecock, is rare. Two untrained badminton players presented with severe ocular trauma during a smash shot from the partner in a 'doubles' game. Both the players developed blind eye (vision <3/60) in spite of immediate treatment. This article describes an unusual mode of severe blunt trauma with a shuttlecock while playing a 'doubles' game, leading to coup-countercoup injury. In addition, the article highlights the need for awareness of the fatal ocular complications and life-long visual disability, especially in untrained badminton enthusiasts.

Prescribing for water sports.

Recreation is a dynamic aspect of modern day life. Providing the ametropic patient with equal access to recreation fulfills the mission of the eye care professional. The astute practitioner must balance the ethical values of prescribing in the best interest of the patient with the desire to do no harm. Knowledge of the demands presented by water sports and of the risks presented by the aqueous environment must be balanced with an understanding of available contact lenses, proper regimens for lens wear and care, and the appropriate use of available protective eyewear. Patient education and instruction is also necessary for the management of risk and to optimize the benefits of vision correction for water sports.

Abstract Background and Purpose Existing imaging modalities of urologic pathology are limited by three-dimensional (3D) representation on a two-dimensional screen. We present 3D-holoscopic imaging as a novel method of representing Digital Imaging and Communications in Medicine data images taken from CT and MRI to produce 3D-holographic representations of anatomy without special eyewear in natural light. 3D-holoscopic technology produces images that are true optical models. This technology is based on physical principles with duplication of light fields. The 3D content is captured in real time with the content viewed by multiple viewers independently of their position, without 3D eyewear. Methods We display 3D-holoscopic anatomy relevant to minimally invasive urologic surgery without the need for 3D eyewear. Results The results have demonstrated that medical 3D-holoscopic content can be displayed on commercially available multiview auto-stereoscopic display. Conclusion The next step is validation studies comparing 3D-Holoscopic imaging with conventional imaging. PMID:23216303

In recent publications, such as Publications 117 and 120, the Commission provided practical advice for physicians and other healthcare personnel on measures to protect their patients and themselves during interventional procedures. These measures can only be effective if they are encompassed by a framework of radiological protection elements, and by the availability of professionals with responsibilities in radiological protection. This framework includes a radiological protection programme with a strategy for exposure monitoring, protective garments, education and training, and quality assurance of the programme implementation. Professionals with responsibilities in occupational radiological protection for interventional procedures include: medical physicists; radiological protection specialists; personnel working in dosimetry services; clinical applications support personnel from the suppliers and maintenance companies; staff engaged in training, standardisation of equipment, and procedures; staff responsible for occupational health; hospital administrators responsible for providing financial support; and professional bodies and regulators. This publication addresses these elements and these audiences, and provides advice on specific issues, such as assessment of effective dose from dosimeter readings when an apron is worn, estimation of exposure of the lens of the eye (with and without protective eyewear), extremity monitoring, selection and testing of protective garments, and auditing the interventional procedures when occupational doses are unusually high or low (the latter meaning that the dosimeter may not have been worn).

2016-10-01

Adverse health effects of radiation exposure to staff in cardiac catheterisation laboratories have been well documented in the literature. Examples include increased risk of cataracts as well as possible malignancies. These risks can be partly mitigated by reducing scatter radiation exposure to staff during diagnostic and interventional cardiac procedures. There are currently commercially available radiation protection tools, including radioprotective caps, gloves, eyewear, thyroid collars, aprons, mounted shields, table skirts and patient drapes to protect staff from excessive radiation exposure. Furthermore, real-time dose feedback could lead to procedural changes that reduce operator dose. The objective of this review is to examine the efficacy of these tools and provide practical recommendations to reduce occupational radiation exposure with the aim of minimising long-term adverse health outcomes.

To assess protection of surgical healthcare workers against HIV and other bloodborne infections in low- and middle-income countries (LMICs). Literature review based on recent studies assessing baseline surgical capacity in LMICs using the WHO Situational Analysis of Access to Emergency and Essential Surgical Care, the Surgeons OverSeas (SOS) Personnel, Infrastructure, Procedures, Equipment and Supplies (PIPES) survey and the Harvard Humanitarian Initiative survey tools. The availability of protective eyewear, sterile gloves and sterilisers was assessed. Thirteen individual country studies with relevant data were identified documenting items from 399 hospitals. The countries included Afghanistan, Bolivia, Gambia, Ghana, Liberia, Mongolia, Nigeria, Sierra Leone, Solomon Islands, Somalia, Sri Lanka, Tanzania and Zambia. Overall, only 29% (79/270) of hospitals always had eye protection. Sterilisers were only available at 64% (244/383) of facilities. Sterile gloves were the most available item, available at 75% of facilities (256/340). Surgical healthcare worker protection for bloodborne infections continues to be deficient in LMICs. Improved documentation of these items should be incorporated into future surgical capacity studies. Policy makers and clinicians should work together to secure resources and interventions that will protect this vital workforce. © 2014 John Wiley & Sons Ltd.

Does the ANSI Z80.3 nonprescription sunglass and fashion eyewear standard go far enough?

PubMed

Barker, F M

1990-06-01

The recent public concern regarding sunglass protection from UV energy has sparked a significant debate among those in the research community and industry. This debate grows out of concern for the known effects of UV energy in producing or contributing to eye effects such as keratitis, cataract formation, and retinal damage. The ANSI Z80.3 Standard addresses itself to this issue by setting levels of UV energy that are permitted to be transmitted in various labeling categories for over-the-counter sunlenses. One important issue is that the ANSI Standard does not provide for an absolute block of UV energy in any category of these lenses. Because the technology to provide this sort of total UV block is currently available, it is argued that there should be at least one category of lens that is fully protective in the UV range.

Most dental practitioners now routinely wear gloves while treating patients. The most commonly used types of gloves contain latex. Latex is also present in other personal protective equipment, such as masks, eyewear and clinic gowns. Increased use of such items, unfortunately, has been linked to adverse skin and mucous membrane reactions. Latex proteins and chemicals associated with the material's production have been implicated. Exposure to such chemicals has also resulted in allergic responses in dental patients. There is a strong movement in the USA to limit exposure to latex in healthcare environments, including dentistry. The aim of this article is to describe past, present and future efforts to create low-latex or latex-free environments.

Experience With Laser Safety In The USA--A Review

Sliney, David H.

1986-10-01

Following several research programs in the 1960's aimed at studying the adverse biological effects of lasers and other optical radiation sources, laser occupational exposure limits were set and general safety standards were developed. Today, the experience from laser accidents and the development of new lasers and new applications have altered the format of the exposure limits and the safety procedures. It is critically important to distinguish between different biological injury mechanisms. The biological effects of ultraviolet radiation upon the skin and eye are additive over a period of at least one workday, and require different safety procedures. The scattered UV irradiance from excimer lasers may be quite hazardous, depending upon wavelength and action spectra. Since laser technology is young, the exposure of an individual in natural sunlight must be studied to evaluate the potential for chronic effects. The safety measures necessary in the use of lasers depend upon a hazard evaluation. The appropriate control measures and alternate means of enclosure, baffling, and operational control measures are presented. Present laser safety standards are explained briefly. Eye protective techniques and eyewear are considered for a variety of sources. The optical properties of enclosure materials are also discussed.

To evaluate the potential occupational health hazards associated with scattered ultraviolet (UV) radiation during photorefractive keratectomy (PRK) using the VISX Star S3 excimer laser. The Laser Vision Center, National Naval Medical Center, Bethesda, Maryland, USA. Intraoperative radiometric measurements were made with the Ophir Power/Energy Meter (LaserStar Model PD-10 with silicon detector) during PRK treatments as well as during required calibration procedures at a distance of 20.3 cm from the left cornea. These measurements were evaluated using a worst-case scenario for exposure, and then compared with the American Conference of Governmental Industrial Hygeinists (ACGIH) Threshold Value Limits (TVL) to perform a risk/hazard analysis. During the PRK procedures, the highest measured value was 248.4 nJ/pulse. During the calibration procedures, the highest measured UV scattered radiation level was 149.6 nJ/pulse. The maximum treatment time was 52 seconds. Using a worst-case scenario in which all treatments used the maximum power and time, the total energy per eye treated was 0.132 mJ/cm2 and the total UV radiation at close range (80 cm from the treated eye) was 0.0085 mJ/cm2. With a workload of 20 patients, the total occupational exposure at 80 cm to actinic UV radiation in an 8-hour period would be 0.425 mJ/cm2. The scattered actinic UV laser radiation from the VISX Star S3 excimer laser did not exceed occupational exposure limits during a busy 8-hour workday, provided that operating room personnel were at least 80 cm from the treated eye. While the use of protective eyewear is always prudent, this study demonstrates that the trace amounts of scattered laser emissions produced by this laser do not pose a serious health risk even without the use of protective eyewear.

Experimental assessment of eye protection efficiency against high speed projectiles.

Work in hazardous zones with the risk of mechanical injuries requires protection with safety spectacles. Mechanical eye injuries with metal foreign bodies are often caused by rotational material machining or production processes with high pressure or high velocity moving parts. Normative regulations restrict to tests with small and fast flying objects (e.g. 6mm ball). The literature does not provide any information about protection capabilities against larger objects with high mass and arbitrary shape. The purpose of this study was to test the protection efficiency of safety spectacles against flying objects. The scope of this paper is to present a new test setup for mechanical impact resistance testing of personal protective eyewear against objects with arbitrary shape and mass. The setup is based on a catapult platform, accelerating a sliding carriage on a rail. A pull rope system allows velocities up to 62±2 m·s(-1). A photo sensor was used for velocity measurement. The carriage can be loaded with projectiles of up to 30mm×30mm×40mm in size with arbitrary orientation, depending on the carriage insert. Testing and validation was done with projectiles such as 7g metal chips and fragments with approximate dimensions of 10mm×15mm. Samples were standard occupational safety spectacles mounted on a test head. The projectile impact was captured with a monochrome high speed camera. The aiming accuracy test showed deviations of approximately 1mm of two impacts on the same spectacle surface with a free flight distance of 150mm. All tests with slow, medium and high speed projectiles showed no contact with the eye medium. Objects with velocities from 10 m·s(-1) to 62 m·s(-1) fired the spectacle off from the test head. The medium speed test cut off one side of the spectacle frame. The high speed test with 62±2 m·s(-1) cracked the polycarbonate shield. We describe a method for accelerating arbitrary objects up to 62 m·s(-1) and for aiming these objects on safety eyewear, mounted on a test head. The setup allows a variety of projectile shapes, orientations and velocities. The accuracy of velocity measurement is ± 2 m·s(-1) for high velocity (< ± 5%). Further studies will address optimization of this setup due to signs of wear and gliding properties of the carriage, wireless ignition and higher velocities. Copyright © 2012.

To evaluate the relative strength and shatter resistance of spectacle lenses currently used in sunglasses and dress, sports, and industrial eyewear. Seven lenses that met the US American National Standards Institute (ANSI) Z80 standards for dress glasses (made of high-index plastic, allyl resin plastic, heat tempered glass, chemically tempered glass, and polycarbonate, and with center thickness ranging from 1 mm to 2.2 mm) and 4 lenses that met ANSI Z87 standards for industrial safety eyewear (allyl resin plastic, heat-tempered glass, chemically tempered glass, and polycarbonate, all with 3.0-mm center thickness) were tested for impact resistance to 5 projectiles (air gun pellets, golf balls, tennis balls, lacrosse balls, and baseballs). Impact energy required to shatter spectacle lenses. Based on 348 lens impacts, dress and industrial lenses made from glass, allyl resin plastic, and high-index plastic shattered at impact energies less than those expected to be encountered from the test projectiles during their routine use. Polycarbonate lenses demonstrated resistance to impact for all tested projectiles exceeding the impact potential expected during routine use. Under the test conditions of this study, polycarbonate lenses demonstrated greater impact resistance than other commonly used spectacle lenses that conform to prevailing eyewear standards. These findings suggest that current ANSI Z80 and ANSI Z87 standards should be reevaluated.

Silhouette's Titan Minimal Art frames possess a super elasticity that ensures a slip-free fit for wearing comfort, without causing irritating pressure points. The titanium alloy used in the frames also prevents allergic reactions. This technology is available to both NASA astronauts and public consumers in either corrective eyewear or sunglass models. The only difference between the sunwear used by NASA astronauts and the commercial models is the lens. Silhouette and Dr. Keith Manuel, the "official" optometrist overseeing the NASA Space Shuttle, the International Space Station, and various other vision-related space projects, brought NASA a lens that is considerably darker (5.5 percent overall light transmittance), with a thin gold coating that offers total protection, not only against ultraviolet (UV) radiation, but also against the harmful infrared radiation in space.

The aim of this study was to evaluate the effectiveness of audiovisual (AV) distraction in behavior modification during dental caries assessment and sealant placement in children with autism spectrum disorder. This study was conducted on 28 children diagnosed with autism spectrum disorder, aged 6.5-9.8 years. Children underwent one introductory (desensitization) appointment and three treatment sessions. During the introductory session, children had the procedures explained to them, they watched a movie projected on a screen while oral screening and assessment of cooperation level were carried out. In treatment session I, oral examination, charting, and dental x-rays were undertaken, whereas the children watched movies with or without video eyewear. During treatment sessions II/III, dental prophylaxis was carried out on upper and lower jaws in addition to the application of dental sealants on the right upper and lower and the left upper and lower permanent molars, respectively, while the children were distracted by cartoon movies using video eyewear. Changes in pulse oximeter and heart rate were recorded every 5 min. Independent samples t -test was used to assess the significance of changes in pulse and O 2 saturation levels during each visit. International Caries Detection and Assessment System-code 2 was found to be the most prevalent ( n = 58; 52%). A significant difference ( P < 0.02) was observed in mean heart rate during dental screening of the upper and lower jaws with and without video eyewear. A decrease was observed in the mean heart rate during subsequent treatment sessions. Initial desensitization appointment and "tell-show-do" approach, followed by short and positive treatment sessions, assisted in gaining cooperation and improving behavior in the subjects. Video eyewear distraction proved an effective tool in managing children with autism spectrum disorder during noninvasive preventive dental procedures.

There were three main objectives of this cross-sectional study of Maryland State correctional health care workers. The first was to evaluate compliance with work practices designed to minimize exposure to blood and body fluids; the second, to identify correlates of compliance with universal precautions (UPs); and the third was to determine the relationship, if any, between compliance and exposures. Of 216 responding health care workers, 34% reported overall compliance across all 15 items on a compliance scale. Rates for specific items were particularly low for use of certain types of personal protective equipment, such as protective eyewear (53.5%), face mask (47.2%) and protective clothing (33.9%). Compliance rates were highest for glove use (93.2%) waste disposal (89.8%), and sharps disposal (80.8%). Compliance rates were generally not associated with demographic factors, except for age; younger workers were more likely to be compliant with safe work practices than were older workers (P < 0.05). Compliance was positively associated with several work-related variables, including perceived safety climate (i.e., management's commitment to infection control and the overall safety program) and job satisfaction, and was found to be inversely associated with security-related work constraints, job/task factors, adverse working conditions, workplace discrimination, and perceived work stress. Bloodborne exposures were not uncommon; 13.8% of all respondents had at least one bloodborne exposure within the previous 6 months, and compliance was inversely related to blood and body fluid exposures. This study identified several potentially modifiable correlates of compliance, including factors unique to the correctional setting. Infection-control interventional strategies specifically tailored to these health care workers may therefore be most effective in reducing the risk of bloodborne exposures.

Waveguide display systems are widely used in various display fields, especially in head mounted display. Comparing with the traditional head mounted display system, this device dramatically reduce the size and mass. However, there are still several fatal problems such as high scatting, the cumbersome design and chromatic aberration that should be solved. We designed and fabricated a monochromatic portable eyewear display system consist of a comfortable eyewear device and waveguide system with two holographic gratings located on the substrate symmetrically. We record the gratings on the photopolymer medium with high efficiency and wavelength sensitivity. The light emitting from the micro-display is diffracted by the grating and trapped in the glass substrate by total internal reflection. The relationship between the diffraction efficiency and exposure value is studied and analyzed, and we fabricated the gratings with appropriate diffraction efficiency in a optimization condition. To avoid the disturbance of the stray light, we optimize the waveguide system numerically and perform the optical experiments. With this system, people can both see through the waveguide to obtain the information outside and catch the information from the micro display. After considering the human body engineering and industrial production, we design the structure in a compact and portable way. It has the advantage of small-type configuration and economic acceptable. It is believe that this kind of planar waveguide system is a potentially replaceable choice for the portable devices in future mobile communications.

Polaris Sensor Technologies has developed numerous 3D display systems using a US Army patented approach. These displays have been developed as prototypes for handheld controllers for robotic systems and closed hatch driving, and as part of a TALON robot upgrade for 3D vision, providing depth perception for the operator for improved manipulation and hazard avoidance. In this paper we discuss the prototype rugged 3D laptop computer and its applications to defense missions. The prototype 3D laptop combines full temporal and spatial resolution display with the rugged Amrel laptop computer. The display is viewed through protective passive polarized eyewear, and allows combined 2D and 3D content. Uses include robot tele-operation with live 3D video or synthetically rendered scenery, mission planning and rehearsal, enhanced 3D data interpretation, and simulation.

Vision, being one of our most important senses, is critically important in the unique working environment of space flight. Critical evaluation of the astronauts visual system begins with pre-selection examinations resulting in an average of 65% of all medical disqualification's caused by ocular findings. With an average age of 42, approximately 60% of the astronaut corps requires vision correction. Further demands of the unique training and working environment of microgravity, variable lighting from very poor to extreme brightness of sunlight and exposure to extremes of electromagnetic energy results in unique eyewear and contact lens applications. This presentation will describe some of those unique eyewear and contact lens applications used in space flight and training environments. Additionally, ocular findings from 26 shuttle and 5 MIR mission post-flight examinations will be presented.

This study was undertaken to evaluate the risk of eye injury in motor vehicle accidents in which airbags deploy. An attempt was made to assess the possible associations between eye injuries and eyewear in these accidents. Retrospective observational case series and literature review with analysis. We conducted a literature review of 62 case reports and articles describing 110 adult cases of eye injury after deployment of an airbag and examined two Finnish accident cohorts. The fatal accident series (FAS; fatal injuries with one or more cars involved) included 121 individuals sitting behind an airbag that deployed (65 survivors), and the Airbag study (AB; nonfatal, relatively serious accidents) included 210 individuals (survivors). The type of eye injury, eyewear, and crash dynamics were studied in each of the reviewed case reports. The fatal accident series and AB studies were analyzed to disclose the eye injuries and use of eyewear and to estimate their possible relation to deployment of airbags. Analysis of the published reports revealed that airbag-induced eye injuries were not more frequently reported among wearers of eyeglasses than among nonwearers. However, open-eye injuries were reported three times more often among eyeglass wearers (P = 0.04), whereas all injuries from airbag chemicals occurred among nonwearers. With the exception of one orbital fracture with hyphema, all eye traumas (n = 7) in the FAS and AB cohorts were mild (eyebrow laceration, lid contusion, bruising). The risk of airbag-related eye injury was 2.5% for any eye injury and 0.4% for severe eye injury. In single accidents when seat belts were used, the risks were 2.0% and 0.5%, respectively. In the accidents from the FAS data no difference was observed in the risk for eye injury between survivors in incidents involving airbag deployment and incidents not involving airbags. This risk was not found to be greater among eyeglass wearers. Despite reported cases in the literature, we found that the risk of severe eye injury from airbags was very low (0.4%) in fatal or relatively serious accidents. Eyewear did not seem to increase this risk but might interfere with the injury pattern.

Laser safety considerations require urologists to wear laser eye protection. Laser eye protection devices block transmittance of specific light wavelengths and may distort color perception. We tested whether urologists risk color confusion when wearing laser eye protection devices for laser soft tissue applications. Subjects were tested with the Farnsworth-Munsell 100-Hue Test without (controls) and with laser eye protection devices for carbon dioxide, potassium titanyl phosphate (KTP), neodymium (Nd):YAG and holmium:YAG lasers. Color deficits were characterized by error scores, polar graphs, confusion angles, confusion index, scatter index and color axes. Laser eye protection device spectral transmittance was tested with spectrophotometry. Mean total error scores plus or minus standard deviation were 13+/-5 for controls, and 44+/-31 for carbon dioxide, 273+/-26 for KTP, 22+/-6 for Nd:YAG and 14+/-8 for holmium:YAG devices (p <0.001). The KTP laser eye protection polar graphs, and confusion and scatter indexes revealed moderate blue-yellow and red-green color confusion. Color axes indicated no significant deficits for controls, or carbon dioxide, Nd:YAG or holmium:YAG laser eye protection in any subject compared to blue-yellow color vision deficits in 8 of 8 tested with KTP laser eye protection (p <0.001). Spectrophotometry demonstrated that light was blocked with laser eye protection devices for carbon dioxide less than 380, holmium:YAG greater than 850, Nd:YAG less than 350 and greater than 950, and KTP less than 550 and greater than 750 nm. The laser eye protection device for KTP causes significant blue-yellow and red-green color confusion. Laser eye protection devices for carbon dioxide, holmium:YAG and Nd:YAG cause no significant color confusion compared to controls. The differences are explained by laser eye protection spectrophotometry characteristics and visual physiology.

We have developed a new device to effectively and quickly stop bleeding. The new device uses a small, 5 W diode laser to heat-up the tip of a modified medical forceps. The laser beam is totally contained within a protective enclosure, satisfying the requirements for a Class I laser system, which eliminates the need to protective eyewear. The new device is used in a manner similar to that of a bipolar electrocautery device. After visual location, the bleeding site or local vessel(s) is grabbed and clamped with the tips of the forceps-like instrument. The laser is then activated for a duration of typically 5 sec or until traditional visual or auditory clues such as local blubbling and popping indicate that the targeted site is effectively cauterized. When the laser is activated, the tip of the instrument, thus providing hemostasis. The new device was evaluated in animal models and compared with the monopolar and bipolar electrocautery, and also with the recently developed ultrasound technology. It has new been in clinical trials for abdominal surgery since September 1997.

Sports eyewear protective standards.

2016-01-01

Eye injuries sustained during sport comprise up to 20 per cent of all injuries to the eye serious enough for medical attention to be sought. The prevalence of eye injuries in sport is not easily assessed due to lack of authoritative participation rates, so most studies report total numbers in a time period. The evidence on the proportion of all ocular injuries that are from sport is reviewed. The relative frequencies in different sports are compared in a qualitative manner and the sports with greater numbers of ocular injuries are detailed. In common with occupational injuries to the eye, most sports eye injuries are considered preventable. The hierarchy of action for occupational risk is detailed and adapted to use in a sports scenario. All the available international, regional and national standards on sports eye protection are detailed and their provisions compared. The major function of the standards is to provide adequate protection against the hazard of the sport concerned. These are detailed and compared as a function of energy transfer. Eye protection must not introduce additional or secondary hazards (for instance, fracturing into sharp fragments on impact) and not introduce features that would deter the wearing of eye protection (for instance, restricting field of view to impede playing the sport). The provisions of the standards intended to limit secondary hazards are detailed and compared. The need for future work in standards writing and the activities of the International Standardization Organization in sports eye protection are detailed. © 2016 Optometry Australia.

High speed AM LCD flat panels are evaluated for use in Field Sequential Stereoscopic (FSS) 3D displays for military and avionic applications. A 120 Hz AM LCD is used in field-sequential mode for constructing eyewear-based as well as autostereoscopic 3D display demonstrators for test and evaluation. The COTS eyewear-based system uses shutter glasses to control left-eye/right-eye images. The autostereoscopic system uses a custom backlight to generate illuminating pupils for left and right eyes. It is driven in synchronization with the images on the LCD. Both displays provide 3D effect in full-color and full-resolution in the AM LCD flat panel. We have realized luminance greater than 200 fL in 3D mode with the autostereoscopic system for sunlight readability. The characterization results and performance attributes of both systems are described.

To determine the prevalence of refractive surgery history in recruits for military service in the Israel Defense Forces (IDF) between 1998 to 2005 and to evaluate the effect of surgery on the recruits' fitness to serve in combat units. Surgeon General's HQ, Medical Corps, Israel Defense Forces. The computerized medical records of all ametropic Israeli army inductees were reviewed. They included spectacle-wearing, contact lens-wearing, and post refractive-surgery individuals who were examined in the recruitment office before their compulsory military service. The extracted data from the personal files consisted of the assignment to combat units of those who had refractive surgery and those who wore corrective eyewear and the first and last military position of all ametropic recruits who were assigned to combat units. Five hundred ninety-seven inductees (513 men, 84 women) had refractive surgery before their military service during the study period. The prevalence of recruits who had refractive surgery increased from 0.8/1000 ametropes in 1998 to 4.9/1000 ametropes in 2005. Significantly more recruits who had surgery (73.5%) than recruits who wore corrective eyewear were assigned to combat units (P<.001). The dropout rate from combat units of the former was significantly lower than that of the latter (13.1% versus 29.2%) (P<.001). More corrective eyewear users had refractive surgery before their IDF military service, and relatively more of them applied for combat duty. The high percentage of recruits who had refractive surgery who serve uninterruptedly in combat units indicates that the procedure has no deleterious effect on the recruits' fitness.

To predict the prevalence of UV radiation (hereinafter, UV) at North American ski resorts using temporal, seasonal, altitudinal, and meteorological factors and associate UV with a set of adult sun protection behaviors. Ultraviolet radiation observations and cross-sectional survey of adults on sun protection were collected. Data were collected at 32 high-altitude ski areas located in western North America from 2001 through 2003. The sample consisted of 3937 adult skiers or snowboarders. Measurements of direct, reflected, and diffuse UV were performed at 487 measurement points using handheld meters and combined with self-reported and observed sun protection assessed for adults interviewed on chairlifts. The strongest predictors of UV were temporal proximity to noon, deviation from winter solstice, and clear skies. By contrast, altitude and latitude had more modest associations with UV and temperature had a small positive relationship with UV. Guest sun safety was inconsistently associated with UV: UV was positively related to adults wearing more sunscreen, reapplying it after 2 hours, and wearing protective eyewear, but fewer adults exhibited many of the other sun protection behaviors, such as wearing hats and protective clothing or using lip balm, on days when UV was elevated. Guests took more sun safety precautions on clear-sky days but took steps to maintain body warmth on inclement days. In future sun safety promotions, adults should be encouraged to wear sunscreen on cloudy days because UV is still high and conditions can change rapidly. They need reminders to rely more on season and time of day when judging UV and the need for sun safety.

Ocular protection from solar ultraviolet (UV) radiation has been emphasized in recent years as a result of the thinning of the ozone layer in the atmosphere. The purpose of this study was to evaluate the absorptive properties of UV tints in CR-39 lenses. We used a spectrophotometer to measure the UV transmittance of three groups of UV tinted CR-39 lenses, including (1) lenses tinted by local optical laboratories: (2) lenses tinted by us, using commercially available dyes: and (3) stock UV lenses that have UV absorptive molecules throughout the lens. We also tested the durability of these tints to daily washing/drying by measuring their UV transmittance characteristics at 3, 6, and 12 months. All the tested lenses absorbed all of the UV-B and at least 99% of UV-A. The durability of these UV tints when exposed to daily washing/drying was excellent: all lenses continued to absorb all of the UV-B and at least 99% of UV-A after 1 year. These data suggest that UV tinted CR-39 lenses provide protection against UV radiation that meets the ANSI Z80.3-1996 Standard for non-prescription sunglasses and fashion eyewear. Furthermore, normal daily washing/drying for 1 year does not cause a significant decrease in the protective effect of the UV tint.

We present a image quality improvement in a parallax barrier (PB)-based multiview autostereoscopic 3D display system under a real-time tracking of positions of a viewer's eyes. The system presented exploits a parallax barrier engineered to offer significantly improved quality of three-dimensional images for a moving viewer without an eyewear under the dynamic eye tracking. The improved image quality includes enhanced uniformity of image brightness, reduced point crosstalk, and no pseudoscopic effects. We control the relative ratio between two parameters i.e., a pixel size and the aperture of a parallax barrier slit to improve uniformity of image brightness at a viewing zone. The eye tracking that monitors positions of a viewer's eyes enables pixel data control software to turn on only pixels for view images near the viewer's eyes (the other pixels turned off), thus reducing point crosstalk. The eye tracking combined software provides right images for the respective eyes, therefore producing no pseudoscopic effects at its zone boundaries. The viewing zone can be spanned over area larger than the central viewing zone offered by a conventional PB-based multiview autostereoscopic 3D display (no eye tracking). Our 3D display system also provides multiviews for motion parallax under eye tracking. More importantly, we demonstrate substantial reduction of point crosstalk of images at the viewing zone, its level being comparable to that of a commercialized eyewear-assisted 3D display system. The multiview autostereoscopic 3D display presented can greatly resolve the point crosstalk problem, which is one of the critical factors that make it difficult for previous technologies for a multiview autostereoscopic 3D display to replace an eyewear-assisted counterpart.

To report 2 cases of ocular chemical burns associated with the use of a swim goggle antifog agent and to review the literature for this and similar antifog products. Case reports and systematic review of the medical literature, material safety data, product safety reports, and consumer reviews. Two males, one 46 years and the other 41 years, were referred to our clinic with chemical burns of the ocular surface after using the same goggle antifog agent while swimming in a triathlon. Both sustained significant epithelial defects. Fortunately, with prompt treatment, both of our patients returned to their baseline vision within a few weeks without suffering sight-threatening complications. These are the first cases of ocular chemical burn secondary to use of an eyewear antifog agent to be reported in the medical literature. Similar reports found in consumer forums suggest that our cases are not isolated and these products may have the potential to cause vision-threatening chemical burns.

Plastic photochromic eyewear: a status report

An estimated 10 million pairs of photochromic prescription lenses were dispensed in the United States in 1989, essentially all based on a silver halide system suspended in an inorganic glass. A significant trend within the ophthalmic industry has been the growth of light-weight plastic lenses. In the United States market, the percentage of prescription eyewear made of plastic is now greater than 70%. With this increasing market penetration of plastic lenses, the desire for an acceptable plastic photochromic lens has also increased. As with any commercial product, in order to achieve consumer acceptance there exist several technical requirements for a plastic photochromic lens. These include the light transmission and color of the lens in both the unactivated and activated states, the speeds of darkening and fading, and the fatigue resistance or lifetime of the photochromic system. These requirements will be defined along with approaches to achieving them. The properties of the commercially available plastic photochromic lenses will be compared with the defined requirements.

Evaluate infection control knowledge, attitude, and practice in Lebanese private dental clinics. A survey including 46 questions related to routine safety procedures was sent to 1150 Lebanese dentists between July 1st and 2nd, 2015. The study sample was selected from the database of registered dentists based on a proportional random sampling ensuring equitable representation of the 5 geographic regions of Lebanon. A subset of 29 questions was used to generate an overall score of compliance (excellent, good, fair, and poor). Comparisons according to gender, type, region, and years of practice were performed. 417 dentists returned the completed questionnaires. 96% expressed concern about infection transmission, 90.6% were vaccinated against Hepatitis B, and 61.8% asked routinely about patients medical history. Only 43% used protective eyewear. Although most dentists (65%) used autoclaves, dry heat was still used. Significant correlations were found between gender and use of personal protective equipment. Less compliance was shown by clinicians with fewer years of experience. In the overall compliance questionnaire, the mean percentage of correct answers was roughly 54% with <5% of the practitioners scoring "excellent." Conclusions . The study found inadequacy of compliance in private Lebanese dental clinics necessitating improved educational training and sustained monitoring by regulatory bodies.

Ultraviolet (UV) radiation potentially damages the skin, the immune system, and structures of the eye. A useful UV sun protection for the skin has been established. Since a remarkable body of evidence shows an association between UV radiation and damage to structures of the eye, eye protection is important, but a reliable and practical tool to assess and compare the UV-protective properties of lenses has been lacking. Among the general lay public, misconceptions on eye-sun protection have been identified. For example, sun protection is mainly ascribed to sunglasses, but less so to clear lenses. Skin malignancies in the periorbital region are frequent, but usual topical skin protection does not include the lids. Recent research utilized exact dosimetry and demonstrated relevant differences in UV burden to the eye and skin at a given ambient irradiation. Chronic UV effects on the cornea and lens are cumulative, so effective UV protection of the eyes is important for all age groups and should be used systematically. Protection of children's eyes is especially important, because UV transmittance is higher at a very young age, allowing higher levels of UV radiation to reach the crystalline lens and even the retina. Sunglasses as well as clear lenses (plano and prescription) effectively reduce transmittance of UV radiation. However, an important share of the UV burden to the eye is explained by back reflection of radiation from lenses to the eye. UV radiation incident from an angle of 135°-150° behind a lens wearer is reflected from the back side of lenses. The usual antireflective coatings considerably increase reflection of UV radiation. To provide reliable labeling of the protective potential of lenses, an eye-sun protection factor (E-SPF®) has been developed. It integrates UV transmission as well as UV reflectance of lenses. The E-SPF® compares well with established skin-sun protection factors and provides clear messages to eye health care providers and to lay consumers.

2015-12-01

The purpose of this study was to evaluate the effects of Immersive Visualization (IV) eyewear on anxious, adult patients during oral debridement. Thirty adult volunteers (n=23 females; n=7 males) were enrolled in the study. Participants were required to be 18 years or older, exhibit at least moderate anxiety (score 9 or higher) on the Corah's Dental Anxiety Scale-Revised (DAS-R), and be generally healthy. Individuals were excluded from participation if they presented with severe dental calculus, periodontal disease, or dental caries, were taking psychotropic drugs, had a history of convulsive disorders, vertigo, or equilibrium disorders, or required antibiotic pre-medication. Subjects received a full mouth oral prophylaxis (supra- and subgingival scaling and selective polishing) by a single experienced dental hygienist. A split mouth design was utilized whereby each subject served as their own control. Subjects were randomly divided into 2 groups: Group A used IV eyewear during the first one-half of the appointment (right side of the mouth) and Group B used IV eyewear during the second one-half of the appointment (left side of the mouth). At screening, medical and dental histories were obtained, full mouth oral examinations were performed, and DAS-R was scored to determine eligibility. At baseline, the DAS-R was re-scored to validate anxiety levels. The Calmness Scale was scored pre- and post-IV treatment on a Likert scale ranging from 1 (very calm) to 7 (less calm). At the end of the study, subjects completed a Post IV Opinion survey. Data were entered into Microsoft Excel for Mac 2011 (Microsoft Corporation Version 14.3.5) and analyzed using SAS® 9.3 statistical software. Thirty subjects with a mean age of 29.9 years completed the study. Data analysis indicated no statistically significant difference between Group A and B with regard to mean DAS-R anxiety levels at baseline (3.15 and 2.40, respectively), with a p-value of 0.07. Data showed a significant difference when comparing the calmness mean scores within Group A pre- and post-IV treatments (4.66 and 2.93, respectively), with a p-value 0.01. Within Group B the data revealed a statistically significant difference between pre- and post-IV treatments (p<0.01, 4.33 and 2.13, respectively). Both treatment groups experienced a decrease in anxiety levels from pre to post IV treatments. Moreover, combined mean calmness scores of the 30 subjects (Group A and B) expressed in mean standard deviation showed there was a decrease from 4.50±1.31 in pre-IV treatment to 2.53±1.17 in post-IV treatment. Further investigation of the data showed that there was a significant correlation between calmness and gender; females reported higher levels of anxiety than men before and after IV treatment. Results from this study support the use of IV eyewear as an effective technique to reduce anxiety in adults during oral debridement. The use of the IV eyewear was well received by all subjects. The portable, affordable and easy-to-operate IV system makes this technique an appealing approach of reducing dental anxiety. Copyright © 2015 The American Dental Hygienists’ Association.

Construction-related ocular injuries are an important cause of vision loss but few studies on the incidence, epidemiology and nature of these injuries exist. Due to the perceived increase in occupation-related eye injuries in non-nationals we aimed to investigate the nature of such injuries presenting to a single eye unit over a two-month period. One hundred and fifty-five patients presenting to the accident and emergency department with construction related ocular injury were examined. Of 155 patients, 80 were Irish and 75 nonnational, of whom 60, 21.3 and 6.7% were Polish, Lithuanian and Romanian, respectively. Common causative factors included hammering, grinding, drilling and splash injury. Average rate of eyewear protection usage was 35%, with attendance at safety courses highest in Irish nationals. A penetrating eye injury rate of 4.9% overall was observed, all in non-nationals. Construction related ocular injury is a serious cause of visual loss in non-nationals. Greater adherence to safety regulations and training is required.

Because forensic medicine workers have a greater occupational risk for infectious diseases, strict rules and measures against infections must be implemented at every stage of forensic medicine practices. In this study, we aim to evaluate the infection control implementations in forensic medicine practices in Turkey.A questionnaire survey was mailed to forensic medicine specialists and residents between April and June 2005. The questionnaire consisted of 36 questions whose designed was based on standard precautions and protective barriers against infectious risks.In all, 111 doctors from 27 different cities responded to the questionnaire. Of those doctors who responded, 43.2% reported performing external examination anywhere. The percentage of doctors performing external examinations who regularly wore gloves, masks, and gowns, and washed hands with a disinfectant were 81.5%, 24.7%, 30.9%, and 81.5%, respectively. The percentage of doctors performing autopsies who regularly wore masks, protective eye-wear, gloves, special gloves, and special boots were 59.6%, 10.6%, 98.9%, 71.3%, and 36.2%, respectively. Only 2 negative pressure rooms were reported.According to these results, precautionary measures against infectious risks in forensic medicine practice in our country are insufficient. Conditions to facilitate and to improve the compliance with infection control procedures must be prepared.

To investigate the characteristics and prognoses of golf ball-related ocular injuries (GROIs) using standardized terminology, classification, and scoring systems. Twenty-two GROI patients were assessed using the Birmingham Eye Trauma Terminology, Ocular Trauma Classification Group (OTCG) classification, and Ocular Trauma Score. Globe preservation and final visual acuity (FVA) were assessed according to the injury severity categorical designation. Fourteen patients were injured on golf courses and eight on driving ranges. Nine patients (40.9%) had open-globe injuries (five ruptures (22.7%), four penetrating injuries (18.2%)). All rupture cases required enucleation, whereas penetrating injury cases did not (the FVA ranged from 20/100 to no light perception). In open-globe injuries, wearing glasses protected against rupture (P=0.008). Thirteen patients sustained closed-globe injuries that were accompanied by lens subluxation (38.5%), choroidal rupture (30.8%), macular commotio retinae (38.5%), and traumatic optic neuropathy (7.7%). Twelve (54.5%) patients had orbital wall fractures. The mean number of related surgeries required was 1.5±1.7 across all patients. Eyes with GROIs had devastating FVA and globe preservation status, especially those with open-globe injuries. Observing golf rules and improving driving-range facilities are essential for preventing GROIs. Protective eyewear may reduce ocular damage from GROIs, especially globe rupture.

In open-globe injuries, wearing glasses protected against rupture (P=0.008). Thirteen patients sustained closed-globe injuries that were accompanied by lens subluxation (38.5%), choroidal rupture (30.8%), macular commotio retinae (38.5%), and traumatic optic neuropathy (7.7%). Twelve (54.5%) patients had orbital wall fractures. The mean number of related surgeries required was 1.5±1.7 across all patients. Conclusion Eyes with GROIs had devastating FVA and globe preservation status, especially those with open-globe injuries. Observing golf rules and improving driving-range facilities are essential for preventing GROIs. Protective eyewear may reduce ocular damage from GROIs, especially globe rupture. PMID:24384962

Purpose Evaluate infection control knowledge, attitude, and practice in Lebanese private dental clinics. Materials and Methods A survey including 46 questions related to routine safety procedures was sent to 1150 Lebanese dentists between July 1st and 2nd, 2015. The study sample was selected from the database of registered dentists based on a proportional random sampling ensuring equitable representation of the 5 geographic regions of Lebanon. A subset of 29 questions was used to generate an overall score of compliance (excellent, good, fair, and poor). Comparisons according to gender, type, region, and years of practice were performed. Results 417 dentists returned the completed questionnaires. 96% expressed concern about infection transmission, 90.6% were vaccinated against Hepatitis B, and 61.8% asked routinely about patients medical history. Only 43% used protective eyewear. Although most dentists (65%) used autoclaves, dry heat was still used. Significant correlations were found between gender and use of personal protective equipment. Less compliance was shown by clinicians with fewer years of experience. In the overall compliance questionnaire, the mean percentage of correct answers was roughly 54% with <5% of the practitioners scoring “excellent.” Conclusions. The study found inadequacy of compliance in private Lebanese dental clinics necessitating improved educational training and sustained monitoring by regulatory bodies. PMID:28642792

VIRTUS is the first United Kingdom (UK) military personal armour system to provide components that are capable of protecting the whole face from low velocity ballistic projectiles. Protection is modular, using a helmet worn with ballistic eyewear, a visor, and a mandibular guard. When all four components are worn together the face is completely covered, but the heat, discomfort, and weight may not be optimal in all types of combat. We organized a Delphi consensus group analysis with 29 military consultant surgeons from the UK, United States, Canada, Australia, and New Zealand to identify a potential hierarchy of functional facial units in order of importance that require protection. We identified the causes of those facial injuries that are hardest to reconstruct, and the most effective combinations of facial protection. Protection is required from both penetrating projectiles and burns. There was strong consensus that blunt injury to the facial skeleton was currently not a military priority. Functional units that should be prioritised are eyes and eyelids, followed consecutively by the nose, lips, and ears. Twenty-nine respondents felt that the visor was more important than the mandibular guard if only one piece was to be worn. Essential cover of the brain and eyes is achieved from all directions using a combination of helmet and visor. Nasal cover currently requires the mandibular guard unless the visor can be modified to cover it as well. Any such prototype would need extensive ergonomics and assessment of integration, as any changes would have to be acceptable to the people who wear them in the long term. Crown Copyright © 2016.

Ionizing radiation management is among the most important safety issues in interventional cardiology. Multiple radiation protection measures allow the minimization of x-ray exposure during interventional procedures. Our purpose was to assess the utilization and effectiveness of radiation protection and optimization techniques among interventional cardiologists in Lithuania. Interventional cardiologists of five cardiac centres were interviewed by anonymized questionnaire, addressing personal use of protective garments, shielding, table/detector positioning, frame rate (FR), resolution, field of view adjustment and collimation. Effective patient doses were compared between operators who work with and without x-ray optimization. Thirty one (68.9%) out of 45 Lithuanian interventional cardiologists participated in the survey. Protective aprons were universally used, but not the thyroid collars; 35.5% (n  =  11) operators use protective eyewear and 12.9% (n  =  4) wear radio-protective caps; 83.9% (n  =  26) use overhanging shields, 58.1% (n  =  18)-portable barriers; 12.9% (n  =  4)-abdominal patient's shielding; 35.5% (n  =  11) work at a high table position; 87.1% (n  =  27) keep an image intensifier/receiver close to the patient; 58.1% (n  =  18) reduce the fluoroscopy FR; 6.5% (n  =  2) reduce the fluoro image detail resolution; 83.9% (n  =  26) use a 'store fluoro' option; 41.9% (N  =  13) reduce magnification for catheter transit; 51.6% (n  =  16) limit image magnification; and 35.5% (n  =  11) use image collimation. Median effective patient doses were significantly lower with x-ray optimization techniques in both diagnostic and therapeutic interventions. Many of the ionizing radiation exposure reduction tools and techniques are underused by a considerable proportion of interventional cardiology operators. The application of basic radiation protection tools and techniques effectively reduces ionizing radiation exposure and should be routinely used in practice.

Ultraviolet (UV) radiation potentially damages the skin, the immune system, and structures of the eye. A useful UV sun protection for the skin has been established. Since a remarkable body of evidence shows an association between UV radiation and damage to structures of the eye, eye protection is important, but a reliable and practical tool to assess and compare the UV-protective properties of lenses has been lacking. Among the general lay public, misconceptions on eye-sun protection have been identified. For example, sun protection is mainly ascribed to sunglasses, but less so to clear lenses. Skin malignancies in the periorbital region are frequent, but usual topical skin protection does not include the lids. Recent research utilized exact dosimetry and demonstrated relevant differences in UV burden to the eye and skin at a given ambient irradiation. Chronic UV effects on the cornea and lens are cumulative, so effective UV protection of the eyes is important for all age groups and should be used systematically. Protection of children’s eyes is especially important, because UV transmittance is higher at a very young age, allowing higher levels of UV radiation to reach the crystalline lens and even the retina. Sunglasses as well as clear lenses (plano and prescription) effectively reduce transmittance of UV radiation. However, an important share of the UV burden to the eye is explained by back reflection of radiation from lenses to the eye. UV radiation incident from an angle of 135°–150° behind a lens wearer is reflected from the back side of lenses. The usual antireflective coatings considerably increase reflection of UV radiation. To provide reliable labeling of the protective potential of lenses, an eye-sun protection factor (E-SPF®) has been developed. It integrates UV transmission as well as UV reflectance of lenses. The E-SPF® compares well with established skin-sun protection factors and provides clear messages to eye health care providers and to lay consumers. PMID:24379652

We report a case of an orbital fracture and an eyeball rupture caused by a golf-club injury. A 75-year-old man was struck in his right eye by a golf club while watching behind his son swinging a hybrid-type golf club at his home. A 70-mm muscle-depth laceration was present in the infraorbital area with active bleeding. Computed tomographic imaging of the face revealed a rupture of the right eyeball; fractures in the superior, medial, lateral, and inferior wall of the right orbit; a fracture in the right zygomaticofrontal junction; and a small amount of pneumocephalus in the parafalx region. Under general anesthesia, evisceration of the right eyeball was performed. Not only golfers but also people just watching or passing by can be injured by an errantly struck golf ball or swung golf club. Elderly people as well as children should be instructed in technique and safety and also be supervised when playing golf. Also, the public should be educated about the risk of eye injuries and the benefits of wearing a protective eyewear.

The prevalence rates of both skin cancers and indoor tanning among the US population are high and have increased substantially in recent years. Low compliance by indoor tanning facilities with safety regulations may place consumers at greater risk of skin and ocular damage. This study quantified the level of compliance by indoor tanning facilities with selected federal and state regulations and recommendations. Tanning facilities (N = 54) in San Diego County, California, were visited by a confederate posing as a prospective customer. Compliance with 13 regulations/recommendations were assessed by either direct query or observation of the presence/absence of signs and warning labels. Operators' responses to 5 risk-based questions also were noted. No facility complied with all 13 regulations/recommendations. Compliance with 3 protective eyewear regulations was high (89%-100%). In contrast, compliance with maximum tanning frequency recommendations (approximately 6%) and parental consent regulations (approximately 43%) was disturbingly low. The investigators recommend instituting mandatory, comprehensive training for operators, as well as systematic compliance monitoring with enforcement of penalties for noncompliance.

To describe the use of mandated safety engineered sharps devices (SESDs) and personal protective equipment in healthcare workers (HCWs) with occupational body fluid exposures (BFE) since the Needlestick Safety and Prevention Act. Two questionnaires were administered, over 3 years, to HCWs who reported sharps or splash BFEs. Descriptive statistics and chi-square analysis were used. Of the 498 questionnaires completed, nurses completed 262 (53%), house staff 155 (32 %), technicians 63 (13%) and phlebotomists 11 (2%). Four (1%) completers reported 'other' and three (1%) reported unknown. Sharps injuries accounted for 349 (70%) of the BFEs. SESDs were utilised 43% (128/299) of the time with a 54% (70/130) activation rate. Phlebotomists (80%; 8/10) and nurses (59%; 79/267) used SESDs more than doctors (27%; 31/86) and technicians (26%; 10/39) ( P <0.0001). Fifty-four percent (185/207) of HCWs reported having had training on SESD use; nurses (64%; 98/154) and phlebotomists (70%; 7/8) significantly more so than house staff (44%; 59/133) and technicians (44%; 21/48) ( P <0.05). Most splash BFEs were to the eyes 73% (91/149). Five percent (4/79) of HCWs used protective eyewear. Systematic regular training, appropriate protocols and iteratively providing the safest SESDs based on HCW experience and technological advances will further reduce the physical and emotional toll of BFEs.

UV Induced Degradation of Polycarbonate-Based Lens Materials and Implications for the Heath Care Field

Experimental research is being carried out at Keene State at the undergraduate level that utilizes facilities in both physics and chemistry to study the effects of mono- and polychromatic UV radiation from various sources, including a Deuterium lamp, a solarization unit (at Polyonics, a local industry), and the Sun, to study the photodegradation of polycarbonate-based lens materials used to produce eyewear. Literature in the field of optometry and ophthalmology indicates a correlation between exposure to the UVB band of natural sunlight and the onset of cataract formation, as well as other eye disorders. The public is usually advised that plastic eyeglass lenses will provide protection from this damaging radiation. It is well known that polycarbonate plastic ``yellows'' when exposed to intense sunlight and, particularly, UV light^1,2, either via photo-Fries rearrangement or by a photooxidative process, forming polyconjugated systems and is an industrial concern primarily for cosmetic reasons. We have preliminary data, however, that indicates that the yellowing'' is an indication of a more sinister problem in the case of eyeglasses in that it is accompanied by an increase in transmissivity in the UVB band where the wearer expects and needs protection. Our group includes a local optometrist who will share results with peers in his field. [1] A. Andrady, J. Polymer Sci., 42, 1991 [2] E. P. Gorelov, Inst. Khim. Fiz., Russian Federation

To ensure vision readiness on the battlefield, the French military has been providing its soldiers with eyewear since World War I. A military refractive surgery program was initiated in 2008. A prospective questionnaire-based investigation on optical correction and quality of vision among active duty members with visual deficiencies stationed in Djibouti, Africa, was conducted in 2009. It revealed that 59.3% of the soldiers were wearing spectacles, 21.2% were wearing contact lenses--despite official recommendations--and 8.5% had undergone refractive surgery. Satisfaction rates were high with refractive surgery and contact lenses; 33.6% of eyeglass wearers were planning to have surgery. Eye dryness and night vision disturbances were the most reported symptoms following surgery. Military optical devices were under-prescribed before deployment. This suggests that additional and more effective studies on the use of military optical devices should be performed and policy supporting refractive surgery in military populations should be strengthened.

This study investigated prescription spectacles ordered from online vendors and delivered directly to the public for compliance with the optical tolerance and impact resistance requirements for eyewear dispensed in the United States. Ten individuals ordered 2 pairs of spectacles from each of 10 of the most visited Internet vendors, totaling 200 eyewear orders. Spectacles ordered consisted of ranges of lens and frame materials, lens styles, and refractive corrections reflecting current distributions in the United States. Evaluations included measurement of sphere power, cylinder power and axis, add power (if indicated), horizontal prism imbalance, and impact testing. We received and evaluated 154 pairs of spectacles, comprising 308 lenses. Several spectacles were provided incorrectly, such as single vision instead of multifocal and lens treatments added or omitted. In 28.6% of spectacles, at least 1 lens failed tolerance standards for at least 1 optical parameter, and in 22.7% of spectacles, at least 1 lens failed impact testing. Overall, 44.8% of spectacles failed at least 1 parameter of optical or impact testing. Nearly half of prescription spectacles delivered directly by online vendors did not meet either the optical requirements of the patient's visual needs or the physical requirements for the patient's safety.

Ultraviolet (UV) irradiation is one of the several environmental hazards that may cause inflammatory reactions in ocular tissues, especially the cornea. One of the important factors that affect how much ultraviolet radiation (UVR) humans are exposed to is travel. Hence, traveling is considered to include a more acute UVR effect, and ophthalmologists frequently evaluate and manage the ocular manifestations of UV irradiation, including UV-induced keratitis. The purpose of this paper is to provide an evidence-based analysis of the clinical effect of UVR in ocular tissues. An extensive review of English literature was performed to gather all available articles from the National Library of Medicine PubMed database of the National Institute of Health, the Ovid MEDLINE database, Scopus, and ScienceDirect that had studied the effect of UVR on the eye and its complications, between January 1970 and June 2014. The results show that UVR at 300 nm causes apoptosis in all three layers of the cornea and induces keratitis. Apoptosis in all layers of the cornea occurs 5 h after exposure. The effect of UVR intensity on the eye can be linked to numerous factors, including solar elevation, time of day, season, hemisphere, clouds and haze, atmospheric scattering, atmospheric ozone, latitude, altitude, longitudinal changes, climate, ground reflection, and geographic directions. The most important factor affecting UVR reaching the earth's surface is solar elevation. Currently, people do not have great concern over eye protection. The methods of protection against UVR include avoiding direct sunlight exposure, using UVR-blocking eyewear (sunglasses or contact lenses), and wearing hats. Hence, by identifying UVR intensity factors, eye protection factors, and public education, especially in travelers, methods for safe traveling can be identified. PMID:29067921

Humans have a remarkable capacity to learn and adapt, but surprisingly little research has demonstrated generalized learning in which new skills and strategies can be used flexibly across a range of tasks and contexts. In the present work we examined whether generalized learning could result from visual–motor training under stroboscopic visual conditions. Individuals were assigned to either an experimental condition that trained with stroboscopic eyewear or to a control condition that underwent identical training with non-stroboscopic eyewear. The training consisted of multiple sessions of athletic activities during which participants performed simple drills such as throwing and catching. To determine if training led to generalized benefits, we used computerized measures to assess perceptual and cognitive abilities on a variety of tasks before and after training. Computer-based assessments included measures of visual sensitivity (central and peripheral motion coherence thresholds), transient spatial attention (a useful field of view – dual task paradigm), and sustained attention (multiple-object tracking). Results revealed that stroboscopic training led to significantly greater re-test improvement in central visual field motion sensitivity and transient attention abilities. No training benefits were observed for peripheral motion sensitivity or peripheral transient attention abilities, nor were benefits seen for sustained attention during multiple-object tracking. These findings suggest that stroboscopic training can effectively improve some, but not all aspects of visual perception and attention. PMID:22059078

Attenuation of midinfrared free electron laser energy with eyewear

NASA Astrophysics Data System (ADS)

Joos, Karen M.; Gabella, William

2005-04-01

Purpose: To determine the attenuation of free electron laser (FEL) energy at several wavelengths through microscope objective and eyeglass lenses. Materials and Methods: The FEL at wavelengths of 2.3 um, 2.5 um, 3.0 um, 3.5 um, 4.0 um, 4.5 um, 5.0 um, 6.45 um, 7.0 um, 7.5 um, and 8.0 um was telescoped using a 500 mm nominal focal length lens and a 200 mm focal length lens. The beam had a final spot of about 3 mm and was passed through a 3 mm aperture and onto the 8 mm active area of a J9LP Molectron detector. The eyeglass sample was placed 3 cm in front of the detector. Energy readings were averaged over multiple pulses. Results: Attenuation varied greatly with wavelength and sample from a low attenuation of 0.46 dB, 90% transmission, for short wavelengths through common glass to greater than 60 dB attenuation (transmission at the detector noise level) for IR safe glass by Aura, Inc. Conclusion: Only the designated laser safety goggles effectively attenuate free electron laser energy at 2.3 um and 2.5 um. A microscope objective lens, polycarbonate, and silica glass eyewear is capable of effectively attenuating FEL energy at wavelengths greater than 4.5 um, but the polycarbonate lenses demonstrated material damage.

Development of Eye Dosimeter Using Additive Manufacturing Techniques to Monitor Occupational Eye Lens Exposures to Interventional Radiologists

NASA Astrophysics Data System (ADS)

Choi, JungHwan

In this project, an eye dosimeter was designed for monitoring occupational lens of the eye exposures targeted to interventional radiologists who are often indirectly exposed to scattered radiation from the patient while performing image-guided procedures. The dosimeter was designed with a computer-aided design software to facilitate additive manufacturing techniques to make the dosimeter. The dosimeter consisted of three separate components that are attached to the hinges and the bridge of the occupational worker's protective eyewear. The produced dosimeter was radiologically calibrated to measure the lens dose on an anthropomorphic phantom of the human head. To supplement the physical design, an algorithm was written that prompts the user to input the element responses of the dosimeter, then estimates the average angle, energy, and resulting lens dose of the exposure by comparing the input with the data acquired during the dosimeter calibration procedure. The performance of the calibrated dosimeter (and the algorithm) was evaluated according to guidelines of the American National Standards Institute, and the dosimeter demonstrated a performance that was in compliance with the standard's performance criteria which suggests that the design of the eye dosimeter is feasible.

Stereoscopic-3D display design: a new paradigm with Intel Adaptive Stable Image Technology [IA-SIT

NASA Astrophysics Data System (ADS)

Jain, Sunil

2012-03-01

Stereoscopic-3D (S3D) proliferation on personal computers (PC) is mired by several technical and business challenges: a) viewing discomfort due to cross-talk amongst stereo images; b) high system cost; and c) restricted content availability. Users expect S3D visual quality to be better than, or at least equal to, what they are used to enjoying on 2D in terms of resolution, pixel density, color, and interactivity. Intel Adaptive Stable Image Technology (IA-SIT) is a foundational technology, successfully developed to resolve S3D system design challenges and deliver high quality 3D visualization at PC price points. Optimizations in display driver, panel timing firmware, backlight hardware, eyewear optical stack, and synch mechanism combined can help accomplish this goal. Agnostic to refresh rate, IA-SIT will scale with shrinking of display transistors and improvements in liquid crystal and LED materials. Industry could profusely benefit from the following calls to action:- 1) Adopt 'IA-SIT S3D Mode' in panel specs (via VESA) to help panel makers monetize S3D; 2) Adopt 'IA-SIT Eyewear Universal Optical Stack' and algorithm (via CEA) to help PC peripheral makers develop stylish glasses; 3) Adopt 'IA-SIT Real Time Profile' for sub-100uS latency control (via BT Sig) to extend BT into S3D; and 4) Adopt 'IA-SIT Architecture' for Monitors and TVs to monetize via PC attach.

Safety and Hazard Analysis for the Coherent/Acculite Laser Based Sandia Remote Sensing System (Trailer B70).

DOE Office of Scientific and Technical Information (OSTI.GOV)

Augustoni, Arnold L.

A laser safety and hazard analysis is presented, for the Coherent(r) driven Acculite(r) laser central to the Sandia Remote Sensing System (SRSS). The analysis is based on the 2000 version of the American National Standards Institute's (ANSI) Standard Z136.1, for Safe Use of Lasers and the 2000 version of the ANSI Standard Z136.6, for Safe Use of Lasers Outdoors. The trailer (B70) based SRSS laser system is a mobile platform which is used to perform laser interaction experiments and tests at various national test sites. The trailer based SRSS laser system is generally operated on the United State Air Forcemore » Starfire Optical Range (SOR) at Kirtland Air Force Base (KAFB), New Mexico. The laser is used to perform laser interaction testing inside the laser trailer as well as outside the trailer at target sites located at various distances. In order to protect personnel who work inside the Nominal Hazard Zone (NHZ) from hazardous laser exposures, it was necessary to determine the Maximum Permissible Exposure (MPE) for each laser wavelength (wavelength bands) and calculate the appropriate minimum Optical Density (ODmin) necessary for the laser safety eyewear used by authorized personnel. Also, the Nominal Ocular Hazard Distance (NOHD) and The Extended Ocular Hazard Distance (EOHD) are calculated in order to protect unauthorized personnel who may have violated the boundaries of the control area and might enter into the laser's NHZ for testing outside the trailer. 4Page intentionally left blank« less

Scatter radiation during interventional radiology procedures can produce cataracts in participating medical personnel. Standard safety equipment for the radiologist includes eye protection. The typical configuration of fluoroscopy equipment directs radiation scatter away from the radiologist and toward the anesthesiologist. This study analyzed facial radiation exposure of the anesthesiologist during interventional neuroradiology procedures. Radiation exposure to the forehead of the anesthesiologist and radiologist was measured during 31 adult neuroradiologic procedures involving the head or neck. Variables hypothesized to affect anesthesiologist exposure were recorded for each procedure. These included total radiation emitted by fluoroscopic equipment, radiologist exposure, number of pharmacologic interventions performed by the anesthesiologist, and other variables. Radiation exposure to the anesthesiologist's face averaged 6.5 ± 5.4 μSv per interventional procedure. This exposure was more than 6-fold greater (P < 0.0005) than for noninterventional angiographic procedures (1.0 ± 1.0) and averaged more than 3-fold the exposure of the radiologist (ratio, 3.2; 95% CI, 1.8-4.5). Multiple linear regression analysis showed that the exposure of the anesthesiologist was correlated with the number of pharmacologic interventions performed by the anesthesiologist and the total exposure of the radiologist. Current guidelines for occupational radiation exposure to the eye are undergoing review and are likely to be lowered below the current 100-150 mSv/yr limit. Anesthesiologists who spend significant time in neurointerventional radiology suites may have ocular radiation exposure approaching that of a radiologist. To ensure parity with safety standards adopted by radiologists, these anesthesiologists should wear protective eyewear.

Eye injuries from foreign body incidents remain prevalent in the workplace setting. Often the professional nurse provides the first line of treatment. The informal class presented at the authors' facility offered a comprehensive, organized presentation of a common injury encountered in the practice of occupational health nursing. Strenghts of the presentation included handouts demonstrating eye eversion technique and a flip chart summarizing the content to be placed in each medical station as quick reference. One challenge involved presenting the information to all nurses. The site encompasses four locations and some nurses function as the only staff in the plant for a given shift. With the support of administration and some creative scheduling, 10 of 17 nurses attended one of three classes offered in one morning, and the remaining 7 were able to view the class on videotape. Videotaping the presentation also provided material for future orientation, as well as an opportunity for review. Overall analysis found this a worthwhile offering relevant to practice. A brief formal written evaluation indicated the objectives for the class were achieved and elicited subjects for future topics. Informal chart reviews to check for documentation of visual acuity testing and eversion of the upper lid for foreign body injuries is another outcome measure currently in progress. In addition, a performance improvement project could be accomplished easily by retrospective chart review of assessment and treatment documentation, and tracking of revisits and referrals. Knowledge of current standards in the assessment, first aid, and treatment of eye injuries is every occupational health nurse's responsibility. However, prevention of foreign body injuries is far superior to any treatment modality available. As highly visible leaders within the occupational setting, nurses can be advocates and role models for safe work practices. Occupational health nurses may promote safe eye practices by actively seeking collaboration with safety departments to continuously monitor and improve eye injury and outcome statistics and use of protective eye-wear. By consistently wearing proper safety eyewear, such as approved goggles or prescription safety glasses with side sheilds, during each and every venture into the work area, occupational health nurses provide a strong role model and have the opportunity to educate employees and encourage safe work practices. It is important to encourage shared responsibility and awareness between workers and management for prevention of foreign body incidents and prompt, accurate treatment when necessary to promote optimal outcome.

UV Induced Degradation of Polycarbonate-Based Lens Materials and Implications for the Heath Care Field

Harkay, J. Russell; Henry, Jerry

2007-04-01

Experimental undergraduate research at Keene State College has utilized facilities in physics and chemistry and at Polyonics, a local firm to study the effects of mono- and polychromatic UV radiation from various sources, including a Deuterium lamp, a solarization unit, a monochromator, and natural sunlight to study the photodegradation of polycarbonate-based lens materials used to produce eyewear using spectrophotometry and FTIR analysis. Ophthalmologic literature indicates a correlation between exposure to the UVB band of sunlight and the onset of cataract formation and macular degeneration. It is well known that polycarbonate plastic ``yellows'' when exposed to intense sunlight and, particularly, UV light either via photo-Fries rearrangement or by a photo oxidative process, forming polyconjugated systems and is a concern primarily for cosmetic reasons. Our data indicates that the ``yellowing'' is an indication of a more sinister problem in the case of eyeglasses in that spectrophotometric comparison shows it is accompanied by an increase in transmissivity in the UVB band where the wearer expects and needs protection. FTIR results indicate a degradation of molecular stabilizers and the appearance of free radicals that indicate a breakdown of the resin's chemical structure.

The visual system has developed to transform an undifferentiated and continuous flow of information into discrete and manageable representations, and this ability rests primarily on the uninterrupted nature of the input. Here we explore the impact of altering how visual information is accumulated over time by assessing how intermittent vision influences memory retention. Previous work has shown that intermittent, or stroboscopic, visual training (i.e., practicing while only experiencing snapshots of vision) can enhance visual-motor control and visual cognition, yet many questions remain unanswered about the mechanisms that are altered. In the present study, we used a partial-report memory paradigm to assess the possible changes in visual memory following training under stroboscopic conditions. In Experiment 1, the memory task was completed before and immediately after a training phase, wherein participants engaged in physical activities (e.g., playing catch) while wearing either specialized stroboscopic eyewear or transparent control eyewear. In Experiment 2, an additional group of participants underwent the same stroboscopic protocol but were delayed 24 h between training and assessment, so as to measure retention. In comparison to the control group, both stroboscopic groups (immediate and delayed retest) revealed enhanced retention of information in short-term memory, leading to better recall at longer stimulus-to-cue delays (640-2,560 ms). These results demonstrate that training under stroboscopic conditions has the capacity to enhance some aspects of visual memory, that these faculties generalize beyond the specific tasks that were trained, and that trained improvements can be maintained for at least a day.

Civil aviation is a major commercial and technological industry in the United States. The Federal Aviation Administration (FAA) is responsible for the regulation and promotion of aviation safety in the National Airspace System. To guide FAA policy changes and educational programs for aviation personnel about vision impairment and the use of corrective ophthalmic devices, the demographics of the civil airman population were reviewed. Demographic data from 1971-1991 were extracted from FAA publications and databases. Approximately 48 percent of the civil airman population is equal to or older than 40 years of age (average age = 39.8 years). Many of these aviators are becoming presbyopic and will need corrective devices for near and intermediate vision. In fact, there has been approximately a 12 percent increase in the number of aviators with near vision restrictions during the past decade. Ophthalmic considerations for prescribing and dispensing eyewear for civil aviators are discussed. The correction of near and intermediate vision conditions for older pilots will be a major challenge for eye care practitioners in the next decade. Knowledge of the unique vision and environmental requirements of the civilian airman can assist clinicians in suggesting alternative vision corrective devices better suited for a particular aviation activity.

Peripheral light-focusing (PLF) is an occult form of ultraviolet radiation (UVR) hazardous to the human eye. In PLF, obliquely incident light is refracted from the peripheral cornea to concentrated sites inside the anterior segment. In the current study, the directionality of this phenomenon for UVR and whether PLF is established in outdoor settings exposed to sunlight were investigated. The protection provided by a UV-blocking contact lens was also evaluated. UVA and UVB sensors were placed on the nasal limbus of an anatomically based model eye. The temporal limbus was exposed to a UV light source placed at various angles behind the frontal plane. PLF was quantified with the sensor output. The ensemble was mounted in the orbit of a mannequin head and exposed to sunlight in three insolation environments within the region of Sydney, Australia. PLF for UVA and UVB was determined with no eyewear or with sunglasses and commercially available soft contact lenses, with and without UV-blocking capability. The intensity of UVA peaked at approximately 120 degrees incidence, the level at which the UVB response was also at its maximum. The intensification of UVA was up to x18.3. The intensity of PLF for UVA and UVB was reduced by an order of magnitude by a UV-blocking contact lens, whereas a clear contact lenses had a much lesser effect. Only the UV-blocking contact lens achieved a significant effect on UVA and UVB irradiance in the urban, beach, and mountain locales (P < 0.056). The results identify another type of sunlight hazard: the peripheral focusing of obliquely incident light. UVR from albedo (reflected ambient light) is capable of establishing PLF in the anterior segment, but this can be shielded by UV-blocking soft contact lenses. Sunglasses may be unable to shield oblique rays, unless side protection is incorporated. Contact lenses can offer UVR protection against all angles of incidence, including the peak-response angle. They can also protect the eye in settings in which the wearing of sunglasses is not feasible or convenient.

This paper describes a sensory system for implementing a human–computer interface based on electrooculography. An acquisition system captures electrooculograms and transmits them via the ZigBee protocol. The data acquired are analysed in real time using a microcontroller-based platform running the Linux operating system. The continuous wavelet transform and neural network are used to process and analyse the signals to obtain highly reliable results in real time. To enhance system usability, the graphical interface is projected onto special eyewear, which is also used to position the signal-capturing electrodes. PMID:22346579

Laser induced damage thresholds and laser safety levels. Do the units of measurement matter?

NASA Astrophysics Data System (ADS)

Wood, R. M.

1998-04-01

The commonly used units of measurement for laser induced damage are those of peak energy or power density. However, the laser induced damage thresholds, LIDT, of all materials are well known to be absorption, wavelength, spot size and pulse length dependent. As workers using these values become divorced from the theory it becomes increasingly important to use the correct units and to understand the correct scaling factors. This paper summarizes the theory and highlights the danger of using the wrong LIDT units in the context of potentially hazardous materials, laser safety eyewear and laser safety screens.

Ocular trauma is a major cause of unilateral blindness and male adults in the working age group have been found to have higher rates of ocular injury. A case of a work-related penetrating ocular trauma with an intraocular foreign body causing an optic disc laceration and consequently a combined retinal arterial and venous occlusion is presented. The patient did not recover useful vision despite early surgical intervention. This case highlights an unusual sequelae following penetrating ocular trauma as well as the importance of safety eyewear for individuals in high-risk occupations.

Objective: This study aimed to assess the level of knowledge, attitudes, and practices regarding infection control procedures among undergraduate dental students. Methods: This was a questionnaire-based cross-sectional survey. A self-administered questionnaire consisting of questions on students’ vaccination status as well as knowledge and attitudes regarding infection control was sent to 600 undergraduate dental students in the fourth, fifth, and sixth year of the Al-Farabi College for Dentistry and Nursing, Riyadh, Saudi Arabia. The collected data were analyzed using SPSS software. The significance level was set at P<0.05. Results: The response rate was 85% (512 out of 600). While the vast majority of students (90%) had been vaccinated against hepatitis, only 37.4% have been assessed for anti-HBs. A total of 98.8% and 90.8% reported always wearing gloves and masks, respectively, during dental procedures. The use of protective eyewear was reported by only 29.2%. A significantly higher proportion of sixth-year students showed a positive attitude toward the treatment of patients with infectious diseases than other students of lower academic years. Approximately one-third of students reported having one or more occupational injuries while treating their patients. Conclusion: Although the students had good knowledge and attitudes regarding infection control, the compliance and practice levels regarding the same were low. Such findings highlight the necessity of continued infection-control education of Saudi dental students. PMID:26199855

In recent years, as the optical-electronic industry developed, polymeric materials were gradually increasing in importance. Polycarbonate (PC) is a good candidate for eyewear applications due to its low weight and transparency. In the case of PC lenses, the deposition of anti-scratch (AS) coatings on the polymer surface is essential for the improvement of the mechanical behavior of the lens. In this work, we present a detailed investigation of the optical and nanomechanical properties of a PC based optical lens and coated by an AS coating as a protective overcoat. The study of the effect of the AS coating on the optical response of the PC lens has been performed by the use of Spectroscopic Ellipsometry (SE) in the IR spectral region, where the characteristic features corresponding to the different bonding configuration of the PC lens and the AS coating were studied. Also, the nanomechanical study of the PC lens, before and after the deposition of the AS coating, performed by nanoindentation measurements revealed the significant enhancement of the mechanical response of the AS/PC lens. More specifically, the AS/PC lens is characterized by enhanced values of hardness and elastic modulus. Finally, the use of AS coating has found to lead to a better scratch resistance and to the reduction of the coefficient of friction (μ) of the PC lens.

Concerns have been expressed for some time regarding the growth of the cosmetic suntanning industry and the potential harmful effects resulting from these exposures. Recently published work has appeared to confirm a link between sunbed use and skin cancer. A previous survey in Oxford some years ago demonstrated significant output variations, and we have attempted to extend and update that work. Ultraviolet A, UVB and blue-light output measurements were made on 50 sunbeds using a radiometer fitted with broad-band filters and detectors. A number of irradiance measurements were made on each sunbed within each waveband so that the uniformity of the output could also be assessed. UVA outputs varied by a factor of 3, with a mean of 13.5 mW/cm2; UVB outputs varied by a factor of 60, with a mean of 19.2 microW/cm2; and blue-light outputs varied by a factor of 2.5, with a mean of 2.5 mW/cm2. Outputs fall on average to 80% of the central value at either end of the sunbed. Facial units in sunbeds ranged in output between 18 and 45 mW/cm2. Output uniformity shows wide variation, with 16% of the sunbeds having an axial coefficient of variation > 10%. UVB output is highly tube-specific. Eyewear used in sunbeds should also protect against blue light.

To determine the rate of ocular trauma in a rural population of southern India and its impact on vision impairment and blindness. A population-based cross-sectional study of 5150 persons 40 years or older in a randomly chosen rural population of 3 districts of southern India. Prospective information on trauma, type and agent of injury, setting of injury, and details of treatment sought for the last episode was recorded with questionnaires after face-to-face interviews. All interviewed subjects underwent a comprehensive ocular examination, including vision estimations, slit-lamp biomicroscopy examinations, and dilated posterior segment examinations. We elicited a history of ocular trauma in either eye from 229 (4.5%) persons, including 21 (0.4%) persons with bilateral ocular trauma. Blunt injuries (n = 124; 54.9%) were the major cause for trauma reported in this population. The most common setting where the ocular trauma occurred was during agricultural labor (n = 107; 46.9%). Nearly three quarters (n = 170; 74.2%) of those reporting ocular trauma sought treatment from an eye specialist (n = 104; 57.8%) and one fifth (n = 37; 20.6%) from a traditional healer. The age-adjusted (adjusted to the population estimates for India for the year 2000) prevalence for blindness in any eye caused by trauma was 0.8% (95% confidence interval [CI], 0.4-1.1). The odds ratios (OR) for trauma were higher for males (OR, 2.2; 95% CI, 1.6-3.0) and laborers (OR, 1.7; 95% CI, 1.2-2.4) and lower for literates (OR, 0.7; 95% CI, 0.5- 0.9). Seeking treatment from a traditional eye healer for trauma was not associated with vision impairment (OR, 1.0; 95% CI, 0.3-3.2) or with blindness (OR, 3.4; 95% CI, 0.2-56.5). Eye care programs may need to consider ocular trauma as a priority in this population, because the lifetime prevalence of ocular trauma is higher than that reported for glaucoma, age-related macular degeneration, or diabetic retinopathy from this population. Simple measures such as education regarding the use of protective eyewear could possibly significantly decrease this preventable cause of visual disability.

"Defense-in-Depth" Laser Safety and the National Ignition Facility

DOE Office of Scientific and Technical Information (OSTI.GOV)

King, J J

The National Ignition Facility (NIF) is the largest and most energetic laser in the world contained in a complex the size of a football stadium. From the initial laser pulse, provided by telecommunication style infrared nanoJoule pulsed lasers, to the final 192 laser beams (1.8 Mega Joules total energy in the ultraviolet) converging on a target the size of a pencil eraser, laser safety is of paramount concern. In addition to this, there are numerous high-powered (Class 3B and 4) diagnostic lasers in use that can potentially send their laser radiation travelling throughout the facility. With individual beam paths ofmore » up to 1500 meters and a workforce of more than one thousand, the potential for exposure is significant. Simple laser safety practices utilized in typical laser labs just don't apply. To mitigate these hazards, NIF incorporates a multi layered approach to laser safety or 'Defense in Depth.' Most typical high-powered laser operations are contained and controlled within a single room using relatively simplistic controls to protect both the worker and the public. Laser workers are trained, use a standard operating procedure, and are required to wear Personal Protective Equipment (PPE) such as Laser Protective Eyewear (LPE) if the system is not fully enclosed. Non-workers are protected by means of posting the room with a warning sign and a flashing light. In the best of cases, a Safety Interlock System (SIS) will be employed which will 'safe' the laser in the case of unauthorized access. This type of laser operation is relatively easy to employ and manage. As the operation becomes more complex, higher levels of control are required to ensure personnel safety. Examples requiring enhanced controls are outdoor and multi-room laser operations. At the NIF there are 192 beam lines and numerous other Class 4 diagnostic lasers that can potentially deliver their hazardous energy to locations far from the laser source. This presents a serious and complex potential hazard to personnel. Because of this, a multilayered approach to safety is taken. This paper presents the philosophy and approach taken at the NIF in the multi-layered 'defense-in-depth' approach to laser safety.« less

One of the main objectives of contemporary dentistry is to preserve healthy tooth structure by applying techniques of noninvasive treatment. Air abrasion is a minimally invasive nonmechanical technique of tooth preparation that uses kinetic energy to remove carious tooth structure. A powerful narrow stream of moving aluminum-oxide particles hit the tooth surface and they abrade it without heat, vibration or noise. Variables that affect speed of cutting include air pressure, particle size, powder flow, tip's size, angle and distance from the tooth. It has been proposed that air abrasion can be used to diagnose early occlusal-surface lesions and treat them with minimal tooth preparation using magnifier. Reported advantages of air abrasion include reduced noise, vibration and sensitivity. Air abrasion cavity preparations have more rounded internal contours than those prepared with straight burs. This may increase the longevity of placed restorations because it reduces the incidence of fractures and a consequence of decreased internal stresses. However, air abrasion cannot be used for all patients, i.e. in cases involving severe dust allergy, asthma, chronic obstructive lung disease, recent extraction or other oral surgery, open wounds, advanced periodontal disease, recent placement of orthodontic appliances and oral abrasions, or subgingival caries removal. Many of these conditions increase the risk of air embolism in the oral soft tissues. Dust control is a challenge, and it necessitates the use of rubber dam, high-volume evacuation, protective masks and safety eyewear for both the patient and the therapist.

Ocular trauma is a major cause of acquired monocular blindness in children. Firework injuries account for 20% of ocular trauma. The purpose of our study was to document the profile of ocular firework injuries in children during the festive season of Diwali and to determine the prevalence of unilateral blindness in them. A retrospective chart analysis of ocular firework injury in children during the festival of Diwali from 2009 to 2013, conducted in a tertiary care eye center in Tamil Nadu, Southern India. Children below 18 years of age with ocular firework injuries who presented to the emergency department for 3 consecutive days - the day of Diwali, 1 day before, and 1 day after Diwali - were included in this study. Eighty-four children presented with firework-related ocular injuries during the study period. Male to female ratio was 4:1 with mean age 9.48 ± 4 years. Forty-four percentage required hospitalization. The prevalence of unilateral blindness in children due to fireworks was found to be 8% (95% confidence interval - 2-13%). Vision 2020 gives high priority to avoidable blindness, especially in children. In our study, for every 12 children who presented with firecracker injury, one resulted in unilateral blindness. This is an avoidable cause of blindness. Awareness needs to be created, and changes in policy regarding sales and handling of firecrackers including mandatory use of protective eyewear should be considered.

To measure the prevalence of dry eye syndrome (DES) among clean room (relative humidity ≤1%) workers from 2011 to 2013. Three annual DES examinations were performed completely in 352 clean room workers aged 20-40 years who were working at a secondary battery factory. Each examination comprised the tear-film break-up test (TFBUT), Schirmer's test I, slit-lamp microscopic examination, and McMonnies questionnaire. DES grades were measured using the Delphi approach. The annual examination results were analyzed using a general linear model and post-hoc analysis with repeated-ANOVA (Tukey). Multiple logistic regression was performed using the examination results from 2013 (dependent variable) to analyze the effect of years spent working in the clean room (independent variable). The prevalence of DES among these workers was 14.8% in 2011, 27.1% in 2012, and 32.8% in 2013. The TFBUT and McMonnies questionnaire showed that DES grades worsened over time. Multiple logistic regression analysis indicated that the odds ratio for having dry eyes was 1.130 (95% CI 1.012-1.262) according to the findings of the McMonnies questionnaire. This 3-year trend suggests that the increased prevalence of DES was associated with longer working hours. To decrease the prevalence of DES, employees should be assigned reasonable working hours with shift assignments that include appropriate break times. Workers should also wear protective eyewear, subdivide their working process to minimize exposure, and utilize preservative-free eye drops.

To describe the characteristics of nail gun-related open-globe injuries. Retrospective series of all patients presenting with open globes secondary to nail gun injury from 2000 to 2010. Data were collected on demographics, setting of accident, presenting clinical examination findings, visual acuity, management, surgical procedures needed, and long-term outcomes. Forty-two patients (43 eyes; mean age, 31.6 years; 100% male; 79% Hispanic) suffered open-globe injury from nail gun accidents. Thirty-seven eyes (86%) sustained injury at work. One of 15 (6.7%) patients, on whom data were available, wore protective eyewear during the incident. Entrance wounds were classified into Zone I (n = 24 [56%]), Zone II (n = 12 [28%]), and Zone III (n = 7 [16%]). Six eyes (14%) had retained intraocular foreign bodies. Mean presenting logarithm of the minimum angle of resolution visual acuity was 1.64 ± 0.83, whereas mean final logarithm of the minimum angle of resolution visual acuity was 1.01 ± 0.96 (P = 0.004). Two eyes (4.7%) had no light perception vision at final examination. Seventeen (40%) patients developed a traumatic cataract, and 2 (4.7%) had dislocated lens fragments. Most common findings on presentation included vitreous hemorrhage (n = 30 [70%]) and hyphema (n = 28 [64%]). Two eyes (4.7%) had a retinal detachment at presentation, and 10 (23%) developed a retinal detachment during follow-up visits. Anatomical success was observed in 11 eyes (92%) with a retinal detachment. Three eyes (7.0%) became phthisical or prephthisical, and 1 was enucleated for severe pain. No eyes developed endophthalmitis or sympathetic ophthalmia. This is the largest compilation of nail gun-related open-globe injury reported to date. Posterior segment complications, noted in the majority of cases, likely contributed to the overall guarded visual outcomes. Preventative measures for eye protection should be strictly followed while using nail guns.

To review the severe acute respiratory syndrome (SARS) infection control practices, the types of exposure to patients with SARS, and the activities associated with treatment of such patients among healthcare workers (HCWs) who developed SARS in Toronto, Canada, after SARS-specific infection control precautions had been implemented. A retrospective review of work logs and patient assignments, detailed review of medical records of patients with SARS, and comprehensive telephone-based interviews of HCWs who met the case definition for SARS after implementation of infection control precautions. Seventeen HCWs from 6 hospitals developed disease that met the case definition for SARS after implementation of infection control precautions. These HCWs had a mean age (+/-SD) of 39+/-2.3 years. Two HCWs were not interviewed because of illness. Of the remaining 15, only 9 (60%) reported that they had received formal infection control training. Thirteen HCWs (87%) were unsure of proper order in which personal protective equipment should be donned and doffed. Six HCWs (40%) reused items (eg, stethoscopes, goggles, and cleaning equipment) elsewhere on the ward after initial use in a room in which a patient with SARS was staying. Use of masks, gowns, gloves, and eyewear was inconsistent among HCWs. Eight (54%) reported that they were aware of a breach in infection control precautions. HCWs reported fatigue due to an increased number and length of shifts; participants worked a median of 10 shifts during the 10 days before onset of symptoms. Seven HCWs were involved in the intubation of a patient with SARS. One HCW died, and the remaining 16 recovered. Multiple factors were likely responsible for SARS in these HCWs, including the performance of high-risk patient care procedures, inconsistent use of personal protective equipment, fatigue, and lack of adequate infection control training.

To determine the eye lens dose of the Interventional Cardiology (IC) personnel using optically stimulated luminescent dosimeter (OSLD) and the prevalence and risk of radiation - associated lens opacities in Thailand. 48 IC staff, with age- and sex- matches 37 unexposed controls obtained eye examines. Posterior lens change was graded using a modified Merriam-Focht technique by two independent ophthalmologists. Occupational exposure (mSv) was measured in 42 IC staff, using 2 OSLD badges place at inside lead apron and at collar. Annual eye lens doses (mSv) were also measured using 4 nanoDots OSL placed outside and inside lead glass eyewear. The prevalence of radiation-associated posterior lens opacities was 28.6% (2/7) for IC, 19.5% (8/41) for nurses, and 2.7% (1/37) for controls. The average and range of annual whole body effective dose, Hp(10), equivalent dose at skin of the neck, Hp(0.07) and equivalent dose at eye lens, Hp(3) were 0.80 (0.05-6.79), 5.88 (0.14-35.28), and 5.73 (0.14-33.20) mSv respectively. The annual average and range of eye lens dose using nano Dots OSL showed the outside lead glass eyewear on left and right sides as 8.06 (0.17-32.45), 3.55(0.06-8.04) mSv and inside left and right sides as 3.91(0.05-14.26) and 2.44(0.06-6.24) mSv respectively. Eye lens doses measured by OSLD badges and nano Dot dosimeter as Hp(10), Hp(0.07) and Hp(3). The eyes of the IC personnel were examined annually by two ophthalmologists for the prevalence of cataract induced by radiation. Copyright © 2017 Associazione Italiana di Fisica Medica.

The effective dose of medical staff members, especially interventional radiologists and cardiologists, is classified as a relatively high level. We measured the dose for interventional cardiologists by using optically stimulated luminescence dosimeters (OSLDs). However, this quantity is not the same as Hp (3). In experiments, the dose at the eye-lens position of a phantom were measured using OSLDs and thermoluminescence dosimeters (TLDs). A conversion factor from dose measured by using TLDs to OSLDs was estimated from these results. In addition, the eye doses of interventional cardiologists in clinical situations were measured, and the effect of eyewear on the eye-lens dose was discussed. © The Author 2016.

Prevalence of Pterygia in Hawaii: Examining Cumulative Surfing Hours as a Risk Factor.

PubMed

Lin, Alexander D; Miles, Ku'ulei; Brinks, Mitchel V

2016-08-01

To examine the association between surfing and pterygium prevalence in Hawaii. A convenience sampling was performed at four beaches on the island of Oahu, Hawaii. A total of 169 individuals were interviewed and underwent penlight examination to assess grade and extent of pterygium. Of 169 participants aged 18-80 years, 88 non-surfers, 41 occasional surfers, 15 recreational surfers and 25 surfing enthusiasts were identified based on their lifetime surfing hours. Overall, 19 participants were found to have pterygia (28 pterygia total) including two non-surfers (2.3%), five occasional surfers (12.2%), three recreational surfers (20.0%), and nine enthusiast surfers (36.0%). Variables associated with pterygium prevalence were lifetime surfing hours (p < 0.0001), outdoor occupation (p = 0.04), Hawaiian residence (p = 0.009), and Hawaiian/Pacific Islander ethnicity (p = 0.002). Multiple logistic regression with the outcome of pterygium was performed, along with multiple linear regression for the continuous outcomes of corneal extent, chord length, and apex-visual axis gap, with lifetime surfing hours as the primary explanatory variable. After adjustment for confounders, a significant linear relationship was observed between chord length and lifetime surfing hours (p = 0.01). Surfing was associated with an increased pterygium prevalence and trend towards an association with increased pterygium severity. Increased risk of exposure to wind, particle irritation, and ultraviolet (UV) radiation while surfing may contribute to pterygium development. Implications for public health include promoting UV protective eyewear during surfing, in addition to raising awareness about the association of pterygia and the sport of surfing.

Welding related occupational eye injuries: a narrative analysis

Lombardi, D; Pannala, R; Sorock, G; Wellman, H; Courtney, T; Verma, S; Smith, G

2005-01-01

Objective: To determine the activities and circumstances proximal to a welding related occupational eye injury, a hybrid narrative coding approach derived from two well developed classification systems was developed to categorize and describe the activity, initiating process, mechanism of injury, object and/or substance, and the use of protective eyewear from the narrative text data reported for each injury. Methods: Routinely collected workers' compensation claims over a one year period (2000) were analyzed from a large US insurance provider. An index term search algorithm of occupation, incident, and injury description fields identified 2209 potential welding related eye injury claims. After detailed review of these claims, 1353 welders and 822 non-welders were analyzed. Results: During 2000, eye(s) as the primary injured body part accounted for 5% (n = 26 413) of all compensation claims. Eye injuries accounted for 25% of all claims for welders. Subjects were mainly male (97.1%) and from manufacturing (70.4%), service (11.8%), or construction (8.4%) related industries. Most injuries were foreign body (71.7%) or burn (22.2%) and 17.6% were bilateral. Common activities include welding (31.9%) and/or grinding (22.5%). Being struck by an airborne object occurred in 56.3% of cases. Non-welders showed similar patterns except that burns (43.8%) were more frequent and more often initiated by another worker (13.9%). Conclusions: Narrative injury text provides valuable data to supplement traditional epidemiologic analyses. Workers performing welding tasks or working nearby welders should be trained to recognize potential hazards and the effective use of proper safety equipment to prevent ocular injury. PMID:15933411

Prevalence of Dry Eye Syndrome after a Three-Year Exposure to a Clean Room

PubMed Central

2014-01-01

Objective To measure the prevalence of dry eye syndrome (DES) among clean room (relative humidity ≤1%) workers from 2011 to 2013. Methods Three annual DES examinations were performed completely in 352 clean room workers aged 20–40 years who were working at a secondary battery factory. Each examination comprised the tear-film break-up test (TFBUT), Schirmer’s test I, slit-lamp microscopic examination, and McMonnies questionnaire. DES grades were measured using the Delphi approach. The annual examination results were analyzed using a general linear model and post-hoc analysis with repeated-ANOVA (Tukey). Multiple logistic regression was performed using the examination results from 2013 (dependent variable) to analyze the effect of years spent working in the clean room (independent variable). Results The prevalence of DES among these workers was 14.8% in 2011, 27.1% in 2012, and 32.8% in 2013. The TFBUT and McMonnies questionnaire showed that DES grades worsened over time. Multiple logistic regression analysis indicated that the odds ratio for having dry eyes was 1.130 (95% CI 1.012–1.262) according to the findings of the McMonnies questionnaire. Conclusions This 3-year trend suggests that the increased prevalence of DES was associated with longer working hours. To decrease the prevalence of DES, employees should be assigned reasonable working hours with shift assignments that include appropriate break times. Workers should also wear protective eyewear, subdivide their working process to minimize exposure, and utilize preservative-free eye drops. PMID:25339991

EPRI Guide to Managing Nuclear Utility Protective Clothing Programs. PCEVAL User`s Manual, A computer code for evaluating the economics of nuclear plant protective clothing programs: Final report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kelly, J.J.; Kelly, D.M.

1993-10-01

The Electric Power Research Institute (EPRI) commissioned a radioactive waste related project (RP2414-34) in 1989 to produce a guide for developing and managing nuclear plant protective clothing programs. Every nuclear facility must coordinate some type of protective clothing program for its radiation workers to ensure proper and safe protection for the wearer and to maintain control over the spread of contamination. Yet, every nuclear facility has developed its own unique program for managing such clothing. Accordingly, a need existed for a reference guide to assist with standardizing protective clothing programs and in controlling the potentially escalating economics of such programs.more » The initial Guide to Managing Nuclear Utility Protective Clothing Programs, NP-7309, was published in May 1991. Since that time, a number of utilities have reviewed and/or used the report to enhance their protective clothing programs. Some of these utilities requested that a computer program be developed to assist utilities in evaluating the economics of protective clothing programs consistent with the guidance in NP-7309. The PCEVAL computer code responds to that industry need. This report, the PCEVAL User`s Manual, provides detailed instruction on use of the software.« less

Descriptive Epidemiology of Collegiate Women's Lacrosse Injuries: National Collegiate Athletic Association Injury Surveillance System, 1988–1989 Through 2003–2004

PubMed Central

Dick, Randall; Lincoln, Andrew E; Agel, Julie; Carter, Elizabeth A; Marshall, Stephen W; Hinton, Richard Y

2007-01-01

Objective: To review 16 years of National Collegiate Athletic Association injury surveillance data for women's lacrosse and identify potential areas for injury prevention initiatives. Background: Women's lacrosse is a fast-paced, primarily noncontact sport. Participation in collegiate women's lacrosse almost doubled between the 1988–1989 and 2003–2004 seasons. Lacrosse equipment consists of sticks made of wood or a synthetic material and a hard rubber ball. Until recently, mouth guards were the only required protective equipment. Main Results: Collegiate women's lacrosse game injury rates increased over the 16-year study period. More than 60% of all severe game injuries were lower extremity sprains and strains and knee internal derangements, most frequently the result of noncontact incidents. The most common injury scenarios by injury mechanism and player activity were no contact while ball handling (16.4%) and contact from a stick while ball handling (10.5%). Contact from a stick or a ball accounted for 5.6% and 5.2% of injuries sustained during shooting activities, respectively. Approximately 22% of all game and 12% of all practice injuries involved the head and neck. Contact from a stick accounted for the majority (56.0%) of above-the-neck injuries in games; contact from the ball accounted for 20.0% of these injuries. Participants had 5 times the risk of sustaining a concussion in a game as in a practice (0.70 versus 0.15 injuries per 1000 athletic-exposures, rate ratio = 4.7, 95% confidence interval = 3.8, 6.5). Recommendations: To reduce the lower extremity injuries that comprise the greatest injury burden in women's lacrosse, future researchers should evaluate proprioceptive, plyometric, and balance training interventions designed specifically for female players. Other research areas of great interest involve determining whether protective eyewear (mandated in 2004) reduces injuries to the eye, orbit, and nasal area and identifying any unintended consequences of the mandate, such as increased risk of injuries to other areas of the face or more aggressive play.

Weaver, J L; McAlister, W H

2001-01-01

In 1996 and 1997, the Army conducted an exercise to assess the ability to rapidly mobilize the reserve forces. In accordance with Army requirements, each soldier was evaluated to determine if he or she met vision and optical readiness standards. Of the 1,947 individuals processed through the optometry section, 40% met vision requirements without correction and 32% met vision requirements with their current spectacles. The remaining 28% required examination. A major impediment to processing reserve units for deployment is the lack of vision and optical readiness. In the mobilization for the Persian Gulf War, significant delays were incurred because of the time required to perform eye examinations and fabricate eyewear. However, as a result of this exercise, current prescriptions will be available in the event of mobilization. To ensure readiness, all units should perform such exercises periodically.

Restocking the optical designers' toolbox for next-generation wearable displays (Presentation Recording)

NASA Astrophysics Data System (ADS)

Kress, Bernard C.

2015-09-01

Three years ago, industry and consumers learned that there was more to Head Mounted Displays (HMDs) than the long-lasting but steady market for defense or the market for gadget video player headsets: the first versions of Smart Glasses were introduced to the public. Since then, most major consumer electronics companies unveiled their own versions of Connected Glasses, Smart Glasses or Smart Eyewear, AR (Augmented Reality) and VR (Virtual Reality) headsets. This rush resulted in the build-up of a formidable zoo of optical technologies, each claiming to be best suited for the task on hand. Today, the question is not so much anymore "will the Smart Glass market happen?" but rather "which optical technologies will be best fitted for the various declinations of the existing wearable display market," one of the main declination being the Smart Glasses market.

Basketball is a popular sport involving significant body contact, which may frequently result in ocular trauma. The aim of this study was to evaluate the characteristics and visual outcomes of retinal detachment associated with basketball-related injury. Retrospective, interventional case series. We reviewed the course of patients who sustained traumatic retinal detachment from basketball-related ocular trauma between 2003 and 2015. Thirteen patients were evaluated for basketball-related traumatic retinal detachment. Twelve (92%) were male and 1 (8%) female, with an average age of 18.2 years. The majority (9 of 13, 70%) of patients had moderate-to-high myopia, and none were using protective eyewear when they sustained the eye trauma. Rhegmatogenous retinal detachment was observed in all eyes. The preoperative mean visual acuity was 20/625 (range, hand motions to 20/20). Initial surgery using scleral buckling alone was performed in most (8 of 13, 62%) of the patients. Retinal reattachment was achieved in 10 (76%) eyes after the first operation and in 12 (92%) at the end of the intervention. The mean follow-up was 3.9 years (range, 4 months to 12 years). The visual acuity during last follow-up was 20/231 (range, light perception to 20/20). In the multivariable analysis, initial visual acuity was an independent factor affecting the final visual outcome (P = .006). Retinal detachment associated with basketball-related injury may cause severe visual loss. In the current study, all retinal detachments were of rhegmatogenous type and commonly occurred in young individuals with myopia. Initial visual acuity was associated with the prognosis. Risk awareness for early detection and intervention are important in these traumas. Copyright © 2017 Elsevier Inc. All rights reserved.

Compliance with infection control practices in an university hospital dental clinic

PubMed Central

Mutters, Nico T.; Hägele, Ulrike; Hagenfeld, Daniel; Hellwig, Elmar; Frank, Uwe

2014-01-01

Aim: Compliance with infection control practices is the key to quality care and excellence in dentistry. Infection control remains one of the most cost-beneficial interventions available. However, implementing control procedures requires full compliance of the whole dental team. The aim of our study was to measure the compliance in daily clinical practice. Methods: The compliance with infection control practices in dentistry by dental health care personnel (DHCP) in a German university dental clinic was observed during clinical work. In addition, a survey was conducted to assess the individual knowledge about infection control procedures. Contamination of the workplace during invasive dental procedures was tested, as well. Results: A total of 58 invasive dental treatments implying close contacts between HCWs and patients were scrutinized. All HCWs (100%) wore gloves during dental work, but in some cases (female dentists: 14.3%; dental assistants: 28.6%) gloves were neither changed nor hands were disinfected between different activities or patient contacts (female dentists: 68.6%; male dentists: 60.9%; dental assistants: 93%). Only 31.4% of female and 39.1% of male dentists carried out adequate hygienic hand disinfection after removing gloves. Male dentists wore significantly more often (100%) protective eyewear compared to 77.1% of female dentists (p<0.05). In addition, most of female dentists (62.9%) and dental assistants (80.7%) wore jewelry during dental procedures. Conclusion: Despite the knowledge of distinct hygiene procedures only a small percentage of dental staff performs hygiene practices according to recommended guidelines. Strict audit is clearly needed in the dental setting to ensure compliance with infection control guidelines to prevent transmission of pathogens. Our results provide insights for the development of a targeted education and training strategy to enhance compliance of dental staff especially of dental assistants with infection control procedures.

Krisanachinda, Anchali; Srimahachota, Suphot; Matsubara, Kosuke

2017-06-01

Workers involved in interventional cardiology procedures receive high eye lens doses if radiation protection tools are not properly utilized. Currently, there is no suitable method for routine measurement of eye dose. In Thailand, the eye lens equivalent doses in terms of Hp(3) of the interventional cardiologists, nurses, and radiographers participating in interventional cardiology procedures have been measured at 12 centers since 2015 in the pilot study. The optically stimulated luminescence (OSL) dosimeter was used for measurement of the occupational exposure and the eye lens dose of 42 interventional cardiology personnel at King Chulalongkorn Memorial Hospital as one of the pilot centers. For all personnel, it is recommended that a first In Light OSL badge is placed at waist level and under the lead apron for determination of Hp(10); a second badge is placed at the collar for determination of Hp(0.07) and estimation of Hp(3). Nano Dots OSL dosimeter has been used as an eye lens dosimeter for 16 interventional cardiology personnel, both with and without lead-glass eyewear. The mean effective dose at the body, equivalent dose at the collar, and estimated eye lens dose were 0.801, 5.88, and 5.70 mSv per year, respectively. The mean eye lens dose measured by the Nano Dots dosimeter was 8.059 mSv per year on the left eye and 3.552 mSv per year on the right eye. Two of 16 interventional cardiologists received annual eye lens doses on the left side without lead glass that were higher than 20 mSv per year, the new eye lens dose limit as recommended by ICRP with the risk of eye lens opacity and cataract.

[The effect of drugs used in treatment of skin disorders on visual system].

Drugs with side effects affecting vision are often used in the treatment of skin disorders. The study evaluated principal groups of medicines which may negatively influence vision and the eye itself. Antimalaric drugs may cause a number of disorders of vision and a diagnosed retinophaty is an absolute contraindication. Retinoids often cause a dry eye condition, which results in intolerance to wearing contact lenses. They can also be a cause of poor nightly vision. Psoralens, used in photochemotherapy, can penetrate to the frontal part of the eye, inducing clouding of the lens and cataract. Glucocorticosteroids, often used in skin conditions, increase intraocular pressure, which may result in development of glaucoma. Methotrexate may also cause complications, such as eyelid edema, conjunctival hyperemia, increased lacrimation and photophobia. A prolonged use of tetracyclines may induce side effect in eye organs. Swelling of the optic nerve head with subsequent decreased vision, and even accumulate of metabolites of tetracycline within the conjunctival were observed. In the study a distinction was made between the medications which may lead to a temporary visual impairment and the medication with a side effect lasting beyond the treatment. It was pointed out that some of the side effects could be avoided or minimised by not combining retinoids and tetracyclines or with the use of protective eyewear during photochemotherapy. An examination by ophthalmologist is a crucial step prior to the treatment with chloroquine, hydroxychloroquine or psoralens. Regular eye exams are necessary when using, especially in a protracted fashion, most of the discussed drugs. Finally, the cooperation between dermatologist and ophthalmologist is fundamental for ensuring patient's safety. © 2016 MEDPRESS.

Projectile metallic foreign bodies in the orbit: a retrospective study of epidemiologic factors, management, and outcomes.

Intraorbital projectile metallic foreign bodies are associated with significant ocular and orbital injuries. The authors sought to evaluate epidemiologic factors, the incidence of associated ocular and orbital injury, and the nature and necessity of surgical intervention in these cases. Charts of all patients with projectile intraorbital metallic foreign bodies seen at our institution (27) over the preceding 7 years were evaluated with respect to age, sex, type of injury, associated ocular and orbital injuries, location of the projectile (anterior, epibulbar, or posterior), postinjury visual acuity, and surgical intervention. The majority of patients were male, between the ages of 11 and 30, and had BB pellet injuries. Thirteen projectiles were lodged anteriorly, 4 were in an epibulbar position, and the remaining 10 were posterior to the equator. Twelve of 13 anterior, and 4 of 4 epibulbar foreign bodies were removed surgically, whereas only 2 of 10 posterior foreign bodies required surgery. No case of surgical intervention resulted in a decrease of visual acuity. Associated ocular injuries were both more common and severe in patients with posteriorly located foreign bodies. Final visual acuity was better at presentation and at discharge in patients with anteriorly located foreign bodies. Intraorbital projectile metallic foreign bodies can be a source of significant ocular morbidity. Management of these cases is dependent on the location of the projectile. Ancillary radiographic studies can be helpful. Surgery to remove the projectile should be considered in each case, but foreign bodies that are not readily accessible often may be left safely in place. Closer regulation of the pellet gun industry, with an emphasis on education and protective eyewear use, would be helpful in reducing these injuries.

Hanford Site Groundwater Protection Management Program: Revision 1

DOE Office of Scientific and Technical Information (OSTI.GOV)

NONE

Groundwater protection is a national priority that is promulgated in a variety of environmental regulations at local, state, and federal levels. To effectively coordinate and ensure compliance with applicable regulations, the US Department of Energy has issued DOE Order 5400.1 (now under revision) that requires all US Department of Energy facilities to prepare separate groundwater protection program descriptions and plans. This document describes the Groundwater Protection Management Program for the Hanford Site located in the state of Washington. DOE Order 5400.1 specifies that the Groundwater Protection Management Program cover the following general topical areas: (1) documentation of the groundwater regime,more » (2) design and implementation of a groundwater monitoring program to support resource management and comply with applicable laws and regulations, (3) a management program for groundwater protection and remediation, (4) a summary and identification of areas that may be contaminated with hazardous waste, (5) strategies for controlling these sources, (6) a remedial action program, and (7) decontamination and decommissioning and related remedial action requirements. Many of the above elements are covered by existing programs at the Hanford Site; thus, one of the primary purposes of this document is to provide a framework for coordination of existing groundwater protection activities. Additionally, it describes how information needs are identified and can be incorporated into existing or proposed new programs. The Groundwater Protection Management Program provides the general scope, philosophy, and strategies for groundwater protection/management at the Hanford Site. Subtier documents provide the detailed plans for implementing groundwater-related activities and programs. Related schedule and budget information are provided in the 5-year plan for environmental restoration and waste management at the Hanford Site.« less

EPRI guide to managing nuclear utility protective clothing programs

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kelly, J.J.

1991-05-01

The Electric Power Research Institute (EPRI) commissioned a radioactive waste related project (RP2414-34) during the last quarter of 1989 to produce a guide for developing and managing nuclear protective clothing programs. Every nuclear facility must coordinate some type of protective clothing program for its radiation workers to insure proper and safe protection for the wearer and to maintain control over the spread of contamination. Yet, every nuclear facility has developed its own unique program for managing such clothing. Accordingly, a need existed for a reference guide to assist with the standardization of protective clothing programs and to assist in controllingmore » the potentially runaway economics of such programs. This document is the first known effort to formalize the planning and economic factors surrounding a nuclear utility protective clothing program. It is intended to be informative by addressing the various pieces of information necessary to establish and maintain an effective, professionally managed protective clothing program. It also attempts to provide guidance toward tailoring the information and providing examples within the report to fit each utility's specific needs. This report is further intended to address new issues and trends occurring throughout the nuclear industry in late 1989 which can have either a significant positive or negative impact on the operations or economics of nuclear protective clothing programs. 1 ref., 11 tabs.« less

Ophthalmic optical coatings: The real world can be more aggressive than you think

NASA Astrophysics Data System (ADS)

Mildebrath, Mark; Klemm, Karl

2007-01-01

Ophthalmic antireflection coatings are not normally considered to be in the same category as other traditional optical coatings with respect to environmental damage. However, as a group, eyeglass lens wearers tend to subject their optical-coated eyewear to a broader and more aggressive range of environmental aggressions than at first imagined. This paper presents the environmental aggressions and, in some detail, the resultant coating defects observed in coated ophthalmic optics. Further, development of test methods for defect replication, to enable product improvements will be discussed. Real-life environments combine thermal, chemical, and mechanical "aggressions" which spectacle lenses are subjected to. These aggressions generate optical coating defects and failure modes involving abrasion, corrosion, and loss of adhesion. In addition, market forces driven by retail customer perceptions lead to product liabilities not normally considered to be of any consequence in traditional optical coating applications.

The Influence of Restricted Visual Feedback on Dribbling Performance in Youth Soccer Players.

2017-04-01

The aim of the current study was to examine the influence of restricted visual feedback using stroboscopic eyewear on the dribbling performance of youth soccer players. Three dribble test conditions were used in a within-subjects design to measure the effect of restricted visual feedback on soccer dribbling performance in 189 youth soccer players (age: 10-18 y) classified as fast, average or slow dribblers. The results showed that limiting visual feedback increased dribble test times across all abilities. Furthermore, the largest performance decrement between stroboscopic and full vision conditions was in fast dribblers, showing that fast dribblers were most affected by reduced visual information. This may be due to a greater dependency on visual feedback at increased speeds, which may limit the ability to maintain continuous control of the ball. These findings may have important implications for the development of soccer dribbling ability.

Manufacturing plastic injection optical molds

NASA Astrophysics Data System (ADS)

Bourque, David

2008-08-01

ABCO Tool & Die, Inc. is a mold manufacturer specializing in the manufacturing of plastic injection molds for molded optical parts. The purpose of this presentation is to explain the concepts and procedures required to build a mold that produces precision optical parts. Optical molds can produce a variety of molded parts ranging from safety eyewear to sophisticated military lens parts, which must meet precise optical specifications. The manufacturing of these molds begins with the design engineering of precision optical components. The mold design and the related optical inserts are determined based upon the specific optical criteria and optical surface geometry. The mold manufacturing techniques will be based upon the optical surface geometry requirements and specific details. Manufacturing processes used will be specific to prescribed geometrical surface requirements of the molded part. The combined efforts result in a robust optical mold which can produce molded parts that meet the most precise optical specifications.

A quantitative approach to assessing the efficacy of occupant protection programs: A case study from Montana.

PubMed

Manlove, Kezia; Stanley, Laura; Peck, Alyssa

2015-10-01

Quantitative evaluation of vehicle occupant protection programs is critical for ensuring efficient government resource allocation, but few methods exist for conducting evaluation across multiple programs simultaneously. Here we present an analysis of occupant protection efficacy in the state of Montana. This approach relies on seat belt compliance rates as measured by the National Occupant Protection Usage Survey (NOPUS). A hierarchical logistic regression model is used to estimate the impacts of four Montana Department of Transportation (MDT)-funded occupant protection programs used in the state of Montana, following adjustment for a suite of potential confounders. Activity from two programs, Buckle Up coalitions and media campaigns, are associated with increased seat belt use in Montana, whereas the impact of another program, Selective Traffic Enforcement, is potentially masked by other program activity. A final program, Driver's Education, is not associated with any shift in seat belt use. This method allows for a preliminary quantitative estimation of program impacts without requiring states to obtain any new seat belt use data. This approach provides states a preliminary look at program impacts, and a means for carefully planning future program allocation and investigation. Copyright © 2015 Elsevier Ltd.

The Zero Hunger and Brazil without Extreme Poverty programs: a step forward in Brazilian social protection policy.

PubMed

Paes-Sousa, Romulo; Vaitsman, Jeni

2014-11-01

Brazilian social protection programs have had consistent effects in reducing poverty and inequality among their respective target-groups: children, adolescents and pregnant and breastfeeding women. In 2011, the Brazil without Extreme Poverty program was launched as a strategy to eradicate extreme poverty by 2014. It makes the promotion of rights the core concept of the official political narrative. This study seeks to provide a systematic description of the Brazil without Extreme Poverty program and its initial results. A review of official documents and academic studies on the social protection programs was conducted. The Brazil without Extreme Poverty program represents an incremental approach to the social protection policies enacted by the previous administration. It advocates a multidimensional and focused approach, funded primarily by the federal government. The strategy subscribes to the international trend of associating social protection with employment and income generation policies.

It is not known whether the social protection networks in the Central American subregion and the Dominican Republic have a nutritional dimension. To explore whether the social protection networks in Central America and the Dominican Republic have a nutritional dimension. A survey was conducted during 2009 of 110 social protection programs and 10 national plans in Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and the Dominican Republic. Most of the social protection programs did not have a nutritional dimension. With few exceptions, the social protection programs were not prepared to prevent undernutrition. There may be a similar situation in other regions. It is recommended to incorporate the nutritional dimension into all social protection programs and social safety nets in Central America and the Dominican Republic as well as in all other countries with low-income populations, worldwide.
