Digital Eye Syndrome Among Tertiary Institution Students in the Post-Covid Era: A Cross-Sectional Study.

Abstract

Background and objectives: This study investigates the prevalence of the symptoms and risk factors of Digital Eye Syndrome (DES) among tertiary institution students in the post-COVID era.

Methods: This is a cross-sectional observational study conducted in a tertiary institution. Participants included students who use digital screens for academic and recreational activities. Inclusion criteria involved students with at least ten minutes of daily screen time. A structured questionnaire was used to assess screen time, symptoms, and ergonomic practices. Data collection included self-reported symptoms of DES and potential risk factors such as screen duration, posture, and lighting conditions. The primary outcomes were the prevalence of DES symptoms, including eye strain, headaches, dryness, and blurred vision, as well as associated ergonomic and behavioral risk factors.

Results: A significant proportion of students reported experiencing symptoms of DES as follows: approximately half of the respondents (49.8%) reported experiencing irritation or a gritty feeling in the eye(s), 26.5% reported a burning sensation in their eyes, eye fatigue (57.6%), sensitivity to bright light (68.7%), and a dry feeling in the eye (25.4%). Additionally, symptoms like blurring of vision (37.1%), itching (41.3%), and tearing (35.8%) were also prevalent among respondents. Statistical analysis (Chi-square test) revealed associations between prolonged screen time (8-11 hours screen time, p = 0.040) which is statistically significant; poor ergonomic practices are not statistically significant (p = 0.444 for lying down, placing the screen below the eye level, p = 0.560) and increased symptom severity.

Conclusions: Symptoms of Digital Eye Syndrome are still prevalent among tertiary institution students in the post-COVID era, exacerbated by prolonged screen use and poor ergonomics. Implementing preventive strategies, such as regular breaks and optimized lighting, may mitigate symptoms. Further studies are recommended to explore the long-term ocular effects of digital devices.
