<strong>Background and Objectives</strong>: The prolonged use of digital screens can cause a set of visual and ocular symptoms known as Computer Vision Syndrome (CVS), which is a common health issue among computer users. This study aimed to estimate the prevalence of CVS among university employees and graduate students in their occupational environment in Iran.<br>
<strong>Methods</strong>: A cross-sectional study was carried out in the Rehabilitation School of Iran University of Medical Science, Tehran, Iran. The study population (n=154) included all university employees and graduate students who spend at least one hour of computer work per day in their workplace. The participants completed a validated self-administered questionnaire. A descriptive analysis was performed and the prevalence of CVS was calculated. The correlations between variables were assessed using the Pearson and Spearman correlation coefficients and non-parametrical tests were used to evaluate the association between CVS and predictor variables, as well as differences between subgroups. <br>
<strong>Results</strong>: The Mean±SD age of the sample was 37.7±11.0 years, 64.3% were women, 57.8% were employee, 56.5% have higher education and the Mean±SD of computer usage time was 5.08±2.2. The total prevalence of CVS was 48.7% and the most frequent symptoms were eye redness (62.3%) and burning (56.5%). A significant positive correlation was found between the number of hours working with a computer and the total score of CVS (Pearson correlation coefficient = 0.248, P=0.02). Moreover, the total score of CVS significantly differed between participants who use six or more hours the computer and those who spend less than six hours (Mann-Whitney U test: P=0.007). <br>
<strong>Conclusion</strong>: This is the first investigation using a validated questionnaire to estimate the prevalence of CVS among computer users in the occupational environment, in Iran. The results show a relatively high prevalence of CVS these populations. The most affected are those who use the computer for a longer duration.<br>
