Abstract— The exponential growth of digital technology has led to unprecedented levels of screen exposure across occupational, educational, and personal contexts. Prolonged use of visual display terminals has been associated with a range of ocular and musculoskeletal symptoms collectively referred to as Digital Eye Strain (DES) or Computer Vision Syndrome (CVS). Poor visual ergonomics—encompassing improper screen positioning, inadequate lighting, prolonged viewing duration, and insufficient visual breaks—has been identified as a significant contributory factor to DES. This study examines the relationship between poor visual ergonomic practices and the prevalence and severity of digital eye strain among prolonged screen users. Drawing upon existing empirical research, ergonomic theory, and occupational health frameworks, the paper explores causal mechanisms, risk factors, symptom patterns, and preventive strategies. The findings underscore a strong association between suboptimal visual ergonomics and increased DES severity, emphasizing the need for ergonomic awareness, institutional interventions, and evidence-based policy measures to mitigate visual health risks in digitally intensive environments.
