Computer Visual Syndrome (CVS) refers to visual disturbances induced by electronic media such as computers, laptops, tablets, and smartphones. This research aimed to determine the association between screen time, vitamin A consumption behavior, and CVS symptoms among preclinical medical students. Ninety-five students from a single class at the Faculty of Medicine, Universitas Islam Sultan Agung, Indonesia, participated in this cross-sectional study. Data were collected using an online survey platform in February 2022. The screen time, vitamin A consumption behavior, and CVS were measured using a validated questionnaire. The average daily screen time of the respondents was more than 10 h, with the majority having a moderate vitamin A consumption patterns (66.3%) and experienced CVS (63.2%). The most prevalent CVS symptom identified among these respondents was eye fatigue (62.1%), while double vision and inflamed or watery eyes were the least reported CVS symptoms (9.5% and 8.4%, respectively). The Chi-Square test revealed that there was no correlation between screen time and CVS (p > 0.05), but there was a significant correlation between vitamin A consumption and CVS (p < 0.05). In conclusion, CVS is observed among preclinical medical students due to increased screen time and decreased vitamin A consumption. Therefore, there is a need to develop strategies to manage screen time and vitamin A consumption among students at risk for developing a CVS during their academic careers.
