Prevalence of Digital Eye Strain and Associated Risk Factors Among Adults: A Cross-Sectional Analytical Study
Dr Ragni Kumari
ABSTRACT
Background: Digital eye strain has emerged as an important occupational and public health concern due to increasing reliance on screen-based devices.
Objective: To estimate the prevalence of digital eye strain and assess its association with prolonged digital device exposure among adults.
Methods: A cross-sectional analytical study was conducted among 507 adults aged 25–50 years, predominantly office workers. Data were collected using a structured questionnaire assessing screen time, device usage, ergonomic practices, and symptoms of digital eye strain. Associations were analyzed using chi-square test and odds ratio with 95% confidence interval.
Results: The prevalence of digital eye strain was 68% (n=345). The most common symptoms included eye fatigue (72%), dryness (64%), and headache (51%). In the high-risk exposure group (mobile use >6 hours/day without regular breaks), 27.6% reported digital eye strain compared to 35.2% in the low-risk group. The association between exposure level and digital eye strain was not statistically significant (OR = 0.70, 95% CI: 0.48–1.04, χ² = 3.21, p =0.073).
Conclusion: Digital eye strain is highly prevalent among adults; however, no statistically significant association was observed with high screen exposure in this study. Preventive strategies focusing on ergonomic education and behavioral modification are recommended.
