Abstract

The computer has become a common item in today's society. It is estimated that approximately 45 million workers directly use computers by staring into video display terminals for hours continuously. This prolonged exposure to video display terminals has been the cause of a visual and ergonomic disorder called "Computer Vision Syndrome". Computer Vision Syndrome is a group of symptoms which crop up from the extended viewing of the video display terminals,when the demands of the task exceed the abilities ofthe viewer. Ayurveda mentioned many common reasons for the eye diseases such as looking at one object for prolong time and looking at an object with glare. The main object of this study is to know the incidence of computer vision syndrome among regular computer users who were having minimum one year exposure, and having minimum eight hours per day exposure. The study was carried out as a survey among 300 volunteer computer professionals working at different centers. The data collected from the survey study was analyzed as simple percentage using Microsoft Offlce Excel 2007.The data was revealed that there is a high prevalence of related signs and symptoms of theComputervision syndrome.
