Abstract

Background: Classroom lighting plays a crucial role in the visual comfort and overall eye health of students. Insufficient ambient lighting, particularly in classrooms that rely heavily on projector-based presentations, may contribute to visual strain and potentially lead to the development or exacerbation of refractive errors. This study aims to investigate the impact of classroom ambient lighting on the eye health of students in Hyderabad, Sindh.

Objective: To explore the correlation between classroom ambient lighting conditions and the prevalence of eye health issues, including refractive errors and visual strain, among students.

Methodology: The study was conducted in various schools across Hyderabad, Sindh, focusing on classrooms with varying levels of ambient light. Light measurements were taken using a lux meter to quantify the lighting conditions. A sample of 300 students was selected, and their eye health was assessed through comprehensive ophthalmic examinations. Data on visual comfort, frequency of eye strain, and other related symptoms were collected via surveys and questionnaires.

Results: The study found that classrooms with lower ambient light levels, particularly those designed for projector use, had a higher prevalence of visual strain and refractive errors among students. A statistically significant correlation was observed between low light conditions and the incidence of myopia. Students exposed to better-lit environments reported fewer symptoms of eye strain and had a lower prevalence of refractive errors.

Conclusion: This study highlights the detrimental effects of insufficient ambient lighting in classrooms on student eye health. Ensuring adequate lighting in educational settings is essential to prevent visual strain and minimize the risk of developing refractive errors. The findings underscore the need for educational policymakers and school administrators to prioritize optimal lighting conditions to promote better eye health among students.
