Abstract
Objective: This cross-sectional study was done to find the prevalence of eye strain and other
ocular morbidities among students in Udupi, Karnataka.
Methods: The study protocol included interview, visual acuity examination using Snellen
chart, and measuring classroom illumination through lux meter.
Results: 26% students had visual morbidity and the most prevalent symptoms of eyestrain
were headache (38.6%), watering of eyes (25.7%), pain around eyes (15.6%) and blurred
vision (11.9%). 55.5% classrooms and 88.4% blackboards did not have proper illumination.
Conclusions: Low classroom illumination levels may be a possible factor for development of
visual morbidity.
