Introduction: Refractive error is among easily detectable cause of visual impairment. It constitutes bulk of avoidable and easily treatable causes of blindness in younger population. Aim of this study was to know the distribution of refractive errors. Method: This study was conducted on patients aged between 5 to 35 years in Rohilkhand region, U.P. 2404 subjects of refractive error were studied 964 Male and 1440 Female. Statistical Analysis was done using Chi Square test and SPSS version 22. Results: Mean age of Male and Female patients were 22.44 and 24.28 years respectively. Refractive error was more common in females 59.9% as compared to males 40.1% in a ratio 3:2. Females were having myopia in higher percentage 46.26% in comparison to males where percentage was 33.79%. Maximum refractive error cases were noticed in age group of >10-20yrs (39.3%) followed by >20-30yrs (28.3%), then >30-35yrs (26.1%) and least in 5-10yrs age group (6.4). Conclusion: Overall refractive errors were more common in Females than Males in our study. This can be due to Females being more exposed to screen and involved in finer work like knitting. According to our study, groups with maximum Refractive error cases are our future generation of >10-20 yrs age group (39.3%) followed by high productive age group >20-30 yrs (28.2%). Both these groups jointly cover bulk of studied sample i.e. 67.5%. Thus by providing them with regular eye checkups and refractive errors correction, we can help in raising socio-economic status of our society.
