Background: Refractive errors are one of the major causes of correctable blindness. Aim: To find the association between watching television and vision of school children aged 10-14 years. Methods: A cross sectional school based study with 600 students of age 10-14 years. Prior informed consent for participation in the study was obtained from their parents. Visual acuity was tested using Snellen?s E chart. Using retinoscopy and subjective refraction, refractive error was categorized as myopia, hypermetropia and astigmatism A standardized questionnaire prepared in their local language was used to collect data on their age, sex and duration of watching television. Data was analyzed by Pearson?s Chi Square test using SPSS software. Results: Prevalence of refractive errors in school children was 16.2 %. Watching television for more than five years was significantly associated with development of refractive errors. ( p = 0.009) Conclusion: A longitudinal follow up of all the children with analysis of various risk factors may be required to give a clearer picture.
