Interdisciplinary Evaluation Of Refractive Errors Among Students In A Deemed University.

Introduction: Refractive error occurs when the eye cannot clearly focus the images on the retina which results in blurred vision. The purpose of this study was to determine the prevalence of various errors of refraction among students, which provides the necessary information that helps to detect the refractive errors at an preliminary stage thereby preventing complications. Materials and methods: The cross-sectional study on interdisciplinary evaluation of refractive errors was conducted on 250 students studying in Saveetha University. A self structured questionnaire has been prepared and uploaded in google forms and was circulated among the sample study population during February to April 2021. At the end of the survey, all the data were collected to assess the individual refractive power of students and tabulated in excel sheets. This data was analyzed and their percentage and proportion was calculated. Results: Totally 250 students responded to the questionnaire, out of which 158 ( 63.2%) students had refractive errors, 77(30.8%) students had difficulty in reading, 55(22.00%) students believed glasses had limiting effects on daily life, 166(66.40%) students are aware of contact lenses, 125(50%) students have controlled power due to regular usage of spectacles, 135(54%) students have difficulty in viewing power point presentation in classes, 144(57.6% ) students have headache due to straining of eye, 173(69.2%) students did regular eye check up. Conclusion: There is a high incidence of refractive errors among the students. This helps in early detection of refractive errors, which is much important to prevent asthenopia and other complications.
