Abstract
Introduction: Refractive error is one of the commonest causes of visual impairment around the world. Undetected and uncorrected refractive errors are particularly a significant problem in school children.

Sample size was calculated to be 400. The 6 to16 years children of selected schools of Guwahati City who were present on the day of the interview were interviewed and examined. Snellen chart, pinhole, a trial box, a trial frame, self illuminated vision box and streak Retinoscope were used to detect refractive error. MS excel package and SPSS11.5 software was use for analysis. Results: Prevalence of refractive errors was 23.5%. Myopia was the major refractive error (81.92%) among total refractive errors, followed by astigmatism (14.89%) and hypermetropia (3.19 %). Majority of the myopic children were of low degree myopia. (89.61%). Study reveals that only 24.47% students were already wearing spectacleswhere asremaining 75.53 % of students are unaware about their problems.
