Aim: The aim was to study the knowledge, awareness, and practice of computer vision syndrome (CVS) in digital device users. Materials and Methods: This was an observational study conducted on 504 healthy students of a medical college. The students underwent an interview in the form of a preset questionnaire. Results: The present study comprised a total of 188 (37.3%) males and 316 (62.7%) females with the mean age of 21.98 ± 4.61 years. Awareness about CVS was poor, i.e., only 32% had ever heard of the term CVS of which around 65% could correctly define it. It was noted that more than half of the participants resorted to incorrect methods for relief of ocular symptoms. Social media was the largest source of information (15.1%). The association of age with awareness, knowledge with respect to definition, blink rate, and source of information was highly significant (P = 0.003, 0.001, 0.001, and 0.01, respectively). The association of profession of the participant with knowledge about blink rate and practice of taking a break was found to be highly significant (P = 0.002 and 0.01, respectively). Awareness about the blink rate and practice of closing eyes was significantly associated with the sex of the participant (P = 0.03 and 0.01, respectively). Conclusion: This study shows that the younger generation has significant knowledge about CVS, but there is a gap in practice. A program studying and addressing the barriers to practice needs to be developed for younger generation.
