Convenient based sampling was done at May-August 2017. Students were divided into two groups Group A who were computer user and Group B who were not computer user. Results: All the students who responded were aware of CVS. The chief presenting symptoms were eyestrain (92%), headache (80%), tiredness and burning sensation (77%), watering (88%) and redness (63.2%). Students using computers reported that focusing from distance to near and vice versa ( P =0.00, ?2 test), blurred vision at a distance ( P =0.006, ?2 test) and blepharospasm ( P =0.03, ?2 test) formed part of the syndrome. The main mode of treatment used was tear substitutes and half of students (50.7%) were not using any spectacles and. They did not have any liking for glasses (65%) or spectral filters. Computer-users were more likely to use sedatives/ anxiolytics ( P = 0.04, ?2 test), spectacles ( P = 0.02, ?2 test) and were conscious frequent blinking ( P = 0.003, ?2 test) than the non-computer-users.
