Results: A total of 320 participants aged between 16 to 55 years were surveyed. The prevalence of symptoms of CVS was found to be 70.3%. 97 (33%) individuals used computer around 4-6 hours per day. The most frequently observed symptom was headache seen in 176 individuals (55.1%) followed by neck, shoulder, wrist or back pain in 155 (48.5%), dryness of eyes in 128 (39.9%) & blurred vision in 118 (36.9%) individuals. 42 participants (12.4%) were aware of CVS. 261 participants (81.6%) took preventing measures and the most common preventive measure was taking breaks in between work. Conclusion: Around 70.3% of surveyed participants experienced symptoms related to CVS. Out of 320 participants only 42 participants (12.4%) 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.
