Background: Uncorrected refractive error is the leading cause of eye problem and the second cause of blindness worldwide. Among children aged 5–15 years, 12.8 million are visually impaired because of refractive errors.
Objective: To assess the magnitude of refractive error among school-going children of Imphal, Manipur, India, and to determine the association between refractive error and variables such as sex, dietary habits, family history, and daily activities such as watching television and using computers.
Materials and Methods: This was a cross-sectional study conducted among upper primary school students (students of classes six and seven) of Imphal from June 21, 2014 to July 8, 2014. Sample size was calculated to be 267. Cluster sampling method was used to select the study participants. Snellen chart, Roman test type chart, and pinhole were used to detect refractive error. Analysis was done using Ï‡2-test and Fisher’s exact test. P value of
