AbstractContext: Computer vision syndrome not only affects physical health but also affects the quality of life significantly. It also hampers productivity of work. Aims: To study the prevalence of symptoms of computer vision syndrome (CVS) among medical students. Settings and design: Institution based cross sectional study was carried out at MRIMS, Hyderabad. Methods and material: 164 Medical students fit as per inclusion and exclusion criteria were given self administered questionnaires. Only completely filled
questionnaires were analyzed for presence of CVS. Statistical analysis: The data was analyzed using chi square for proportions and student’s t test for mean values. Results: Though the use of VDU (87.8%) was very high but the awareness was seen only among 15.2% of the users. The most common symptom was eye strain (43.9%). Though the prevalence of symptoms of CVS was more but its association with working on VDUs was not found to be statistically significant for any of the symptoms. The total mean
exposure to VDU for all symptoms was more among those with positive symptoms but the difference was not found to be statistically significant. Eyestrain and watering were found to be significantly more among those whose mean duration of working on VDU was more than four hours compared to those who worked for less than four hours daily. Conclusion: Though majority was using VDU, the level of awareness was very low. Prevalence of symptoms of CVS was very high.
