AbstractBackground: Computer vision syndrome is a complex of eye and vision problems related to near work which are experienced due to prolonged computer use. Computers demand near work, for longer duration which increases discomfort of eye and prolonged exposure to the discomfort leads to a cascade of symptoms that can be referred as computer vision syndrome.
Aim: The study to determine the prevalence of computer vision syndrome among computer users of Bihar state.
Material and methods: This was a Descriptive, Cross-sectional, non-randomized, questionnaire based study conducted in the Department of Ophthalmology, Patna Medical College and Hospital, Patna, Bihar, India, for 1 year. 100 individuals of both gender, who were asked to fill a set of questionnaire to get their personal information including demographic data (age, gender, occupation) and information regarding computer usage and individuals within age group of 20-60 years, spending 4 hours or more in front of a visual display terminal and not known to be suffering from any ocular disorder such as chronic ocular allergy, conjunctivitis, glaucoma, etc other than refractive errors were included in this study.
Results: All the 100 individuals fulfilling the inclusion criteria responded to the questionnaire completely. The mean age of the participants was 24.74 years (20-60 years) among whom females (57%) were more than males (43%). The prevalence of computer vision syndrome was found to be 69%. About 30 (30%) individuals used computer around 4 - 6 hours per day. The most disturbing symptom was eyestrain and fatigue in 59 (59%), headache 57 (57%), pain in neck, shoulder, wrist or back in 51(51%), dryness of eyes in 37 (37%) & blurred vision in 35 (35%) individuals. 11 participants (11%) were aware of CVS. 79 participants (79%) took preventing measures and the most common preventive measure was taking breaks in between work. In the present study 46(46%) participants took breaks as preventive measure after 1 hr and 25 (25%) after 20 minutes.
Conclusion: we concluded that the only 11 participants (11%) were aware of CVS. Some of the strategies found beneficial in reducing the symptoms are keeping the computer screen away which reduces eye strain, taking regular small breaks, maintaining good sitting posture to avoid neck pain and back pain, correction of visual problems and optimum room lighting
