Purpose: To estimate the prevalence of computer vision syndrome (CVS) in presbyopic digital device workers using two ophthalmic progressive lens designs during the working day, and to analyse the association of CVS with sociodemographic, occupational, digital device exposure and refractive factors.
Methods: This time series, quasi-experimental design study included 69 presbyopic digital device workers (age range: 46-69 years; mean ± SD = 54.7 ± 5.0). All used desktop computers at their workplace. Progressive addition lenses (PALs) and occupational lenses were used for three months each. CVS was measured with the CVS-Q questionnaire before intervention (baseline) and at 1 week, 1 month and 3 months after wearing the lenses. A multivariate logistic regression model was used to identify the factors that were associated with an improved CVS-Q score.
Results: 37.7% of the subjects were female and 78.3% were ametropes; 65.2% had advanced presbyopia. 56.2% used digital devices at work >6 h day . The prevalence of CVS at baseline, after wearing PALs for three months and after three months of occupational lens wear was 68.1%, 33.3% and 18.8%, respectively. The mean CVS-Q score was lower with occupational lenses than with PALs (p = 0.001). 40.6% of the digital device workers improved their CVS-Q score ≥2 points with the occupational lenses. Ametropes were less likely than emmetropes to improve with occupational lenses (OR = 0.27, p = 0.05). 89.8% of the sample workers were satisfied or very satisfied with the occupational lenses and 71% were similarly satisfied with the PALs. 73.9% chose the occupational lenses as their first choice of lens for digital device use, compared with 17.4% for PALs.
Conclusions: Computer vision syndrome is reduced in presbyopic desktop computer workers wearing occupational lenses compared with PALs, especially in emmetropes.

Purpose: We conducted a questionnaire survey on the measures to be taken after the reduction of the equivalent dose limit for lenses to clarify the current situation at each institution and to discuss future dose control and exposure protection for lenses.
Methods: A questionnaire survey was conducted among medical institutions in the Tokai area. A total of 65 items, including personal dosimeters, protective eyewear, imaging conditions, and protective equipment, were included in the survey.

Ionizing radiation is considered as a harmful factor to health. However, X‑rays are widely used in diagnostic and therapeutic procedures such as those performed during cardiac interventions. Their use is particularly invaluable in saving life procedures when the risk of adverse effects of radiation is relatively low compared to the consequences of non-treated or treated with other invasive methods diseases.

Background: Modern workplace requirements in the banking sector require bankers to work on screens for more than 6 h a day, putting much stress and strain on their eyes, which leads to computer vision syndrome. Therefore, this study aimed to assess the prevalence of computer vision syndrome and associated factors among urban and rural bankers in Trinidad and Tobago.
Methods And Materials: A cross-sectional design was applied to collect data from 399 bankers between April and June 2023.

The usage of smart glasses in goods logistics and order picking has mainly been studied through cross-sectional experimental studies. Our longitudinal field study investigated the effects of smart glasses on the eyesight of 43 employees at two German companies. We combined ophthalmological examinations and questionnaire surveys at two points in time, six months apart.

Introduction: Climate change threatens the environments in which person-centred occupational therapy occurs. Environmental sustainability is directly linked with the health and wellbeing of current and future generations, presenting occupational therapists with a unique advocacy and activist role. As practitioners of the future, there is an urgent need to understand students' attitudes, perceptions of, and self-perceived preparedness for, dealing with environmental determinants of health and intergenerational occupational and climate justice.
