| dc.description.abstract | Computer Vision Syndrome (CVS) is a group of visual symptoms experienced in relation to the use of computers. Nearly 60 million people suffer from CVS globally, ranging from 64% to 90%, resulting in reduced productivity at work and reduced quality of life of the computer worker. The present study aims to describe the prevalence of CVS and its associated factors among undergraduates in University of Colombo, School of Computing.A cross sectional study was carried out in the University premises on 2nd, 3rd and 4th year students of University of Colombo School of Computing. Pattern of computer use, prevalence and extent of visual symptoms and some associated factors were analyzed. Statistical data is provided about the prevalence of visual symptoms and its co-relationship with the duration of exposure and associated other factors that have been identified. For the categorical variables chi square test was used and for continuous variables Students T Test was used. Sample size was 112 (response rate – 74.6%). Mean age was 21.9±1.2 years (range 19-25 years) and 73 (65.2%) of the sample were males. Only 39 (34.8%) of the sample were females. Percentage of individuals with visual symptoms in the study population was 79 (70.5%). 33 (29.5%) students were asymptomatic. The most commonly reported complaint was headache (54.5%), followed by pain (33.9%), whereas the least common complaint was double vision (3.6%). High prevalence of visual symptoms was observed (70.5%) among the study group. Technology professionals who have nearly similar exposure to the computer screens have shown similar percentage of prevalence of visual symptoms but findings are much more less than the researches which were done on students. There is no association between prevalence of visual symptoms and duration of continued gaze upon the monitor and the duration of the course. But there is a significant association with the distance from the monitor and duration of daily computer usage. | en_US |
