Pak J Med Health Sci Jan ;12(1):157-60.

Aim: To estimate the prevalence of undetected refractive errors among school going children aged 5- 10 yr. Methods: The study was conducted in 2017 in four schools of Lahore. This study is an institutional based cross-sectional study in which structured pre-tested questionnaire was used and 200 students aged 5-10 years were visually examined. Student who had visual acuity less than 6/12 were advised to get proper eye examination and correction by trained professionals. Data was analyzed by using SPSS version 21. Results: A total of 200 students were examined. According to the results, the students involved in this study had a mean age of 7 years +/-1.7 years with 47% being females and 53% males. 116 students included in the study belong to age group 5-7 years (58%) and 84 belong to age group 8-10 years (42%). The results revealed that 35 out of 200 students (17.5%) had refractive errors. Myopia was affecting 28 out of 35 students being more common than hypermetropia which affected 7 out of 35 students. Strong correlation was found between a positive family history of wearing glasses, watching television closely, overindulgence in video and computer games, close study habit and studying in dim light Conclusion: Myopia was the most common refractive error occurring among students examined. It was concluded that a strong association was present between a positive family history of refractive error, watching television at close distance and over indulgence of students in playing video and computer games. It is recommended that eye care services should be integrated in the schools and annual eye examination of all students should be done to timely detect the presence of refractive errors.
