However, their usage can lead to vision issues, such as Computer Vision Syndrome (CVS). Accordingly, this study examines the syndrome among employees of Sabzevar University of Medical Sciences and explores the factors contributing to its occurrence. Methods: This study examined 86 employees from three areas: students, education, and research. It was descriptive and analytical. A validated questionnaire was used to gather data on demographics and CVS symptoms. Screen and room brightness were measured using a Hagner S4 photometer. Data analysis was performed using t-tests and descriptive statistics in Stata. Results: Among the 86 employees, 51 were female and 35 were male. The majority of individuals affected by CVS aged between 30 and 40. Thirty-one employees exhibited early signs of CVS, with the highest prevalence seen in the research department (46.15%). Gender was the sole contributing variable, with a higher prevalence among women (p = 0.035). The overall prevalence of CVS was 34.88%. Conclusion: CVS is a prevalent syndrome among employees. Furthermore, female employees displayed a higher prevalence of CVS. To improve employee well-being and performance, ergonomic training and visual exercises should be trained and implemented in the workplaces. https://ijoh.tums.ac.ir/index.php/ijoh/article/view/690 https://ijoh.tums.ac.ir/index.php/ijoh/article/download/690/880
