Abstract
Refractive error is the most common ocular morbidity worldwide. Throughout the world the main causes of visual impairment are uncorrected refractive errors 43% followed by cataract 33% and glaucoma in 3 % cases. Children being unaware of their problem do not complain about it. Untreated refractive error can lead to amblyopia and poor school performance which in long run can lead to considerable impact on child’s future. A Hospital based cross sectional observational study was conducted in the ophthalmology department of NMCH, Patna, Bihar. Total 612 children of age group 5 to 16 years coming to the OPD were enrolled in the study. Myopia is the most common refractive error in childhood. It is corrected by using concave lens. Other types of refractive errors are hypermetropia and astigmatism. Uncorrected refractive errors among children have considerable impact on their learning & academic achievements. So, screening is the only way for early detection of refractive errors. Early diagnosis and treatment will prevent onset of amblyopia & visual disability.
