Abstract :

Background A refractive error may be defined as a state in which the optical systemic of the non–accommodating eye fails to ing parallel rays of light to focus on the retina. Objective To determine the prevalence of errors of refraction among children in age group 9 to 13 yrs in Govt.U.P School Vencode. Thiruvananthapuram. Material and methods Study Design:Cross–sectional study.Methodology :A descriptive study on errors of refraction in school going children was conducted in a rural area at Govt.School of Vencode. A sample of 62 students was selected from the age group 9–13 yrs. Prevalence of refractive errors among male and females was estimated. Setting: Govt.U.P School of Vencode.Participants:62 school going children of age group 9–13yrs.Study period:Sept 27– Oct 5 2013 Results : Prevalence of refraction is 14.52%. Myopia was the most common among them Conclusion. Among school children prevalence of refractive error, particularly Myopia is high. Early detection can improve the academic performance of children
