Abstract
Introduction: Refractive Error is an avoidable cause of visual impair-ment. Treatment of refractive errors is perhaps the simplest and effective forms of eye care. Objectives: This study was carried out to assess the prevalence and de-terminants of refractive errors among school children of 5th-10th standard. Materials& Methods: Study Design: cross sectional study Sampling technique: stratified random sam-pling. Study participants: A total of 1020 students were included in the study.510 students from each school. All students were screened for defective vision with the help of Snellen‟s chart and optometrist confirmed the findings. Data was analysed to find the prevalence of refractive errors and also to find the determinants using percentages and chi-square tests. Results: 21.7% of students were found to have refractive errors. Children residing in the urban ar-ea(24.6%) were found to have more refractive errors compared to chil-dren residing in rural ar-ea(18.6%).Family history of refrac-tive error was significantly associat-ed with prevalence of refractive er-rors.(p<0.001). Conclusion: Boys were having higher prevalence of refractive er-rors compared to girls. Myopia was the most common form of refractive error. Regular eye screening should be done in school level. IEC activi-ties should play a major role in eye health.
