Comment on “Computer Vision Syndrome in Medical Students in a Tertiary Care Teaching Hospital: A Cross-sectional Study”

Dear Editor, I read with great interest the article titled “Computer Vision Syndrome in Medical Students in a Tertiary Care Teaching Hospital: A Cross-sectional Study” by Hashim and Gotekar[1] The study provides important insights into the prevalence of computer Vision syndrome (CVS) among medical students – a subject of growing relevance in the digital learning era. The reported prevalence of 81.9% underscores a significant concern. I appreciate the use of the validated CVS-Q questionnaire, which strengthens the study’s reliability in symptom evaluation. However, I would like to offer some suggestions that might enhance future studies in this domain. First, the inclusion of ergonomic assessments (such as posture and screen alignment) and ambient lighting conditions could help provide a more comprehensive understanding of contributing factors. Rosenfield (2011) has emphasized the importance of such variables in digital eye strain assessment.[2] Second, the role of screen brightness, blue light exposure, and digital breaks may be worth exploring, especially in the context of sleep disturbances and visual fatigue.[3] I also encourage the exploration of preventive strategies such as structured digital hygiene education, the 20-20-20 rule, and visual aids such as blue light filters or antireflective spectacles in future interventional models. I commend the authors for this relevant contribution and hope it stimulates further academic dialogue and institutional efforts toward mitigating CVS in student populations.
