Screen time has become an unavoidable part of the daily life of school-going children due to online education, smartphones, tablets, television, digital gaming, and social media. Although digital devices have educational and recreational value, excessive and unregulated screen exposure may adversely affect ocular health, visual development, sleep, posture, and overall wellbeing. Children are particularly vulnerable because their visual system is still developing, their self-regulation is limited, and they may use screens at shorter viewing distances for longer durations. The common eye-related problems associated with excessive screen time include digital eye strain, dryness, burning sensation, watering, redness, headache, blurred vision, accommodative fatigue, convergence problems, and progression of myopia. Reduced outdoor activity, prolonged near work, poor lighting, improper posture, and inadequate breaks further increase the risk of visual discomfort and refractive errors. This article reviews the adverse effects of screen time on eyes and vision among school-going children and discusses preventive strategies including parental supervision, school-based screen hygiene, outdoor activity, ergonomic correction, regular eye examination, and simple eye-care practices. The article also briefly highlights Ayurvedic preventive perspectives such as Netra Paricharya, Dinacharya, proper sleep, Pathya Ahara, and avoidance of Atiyoga of Chakshurendriya.
