ABSTRACT
BACKGROUND
Extensive use of various video display terminals (VDT) including smart phones for learning as well as for other fun activities by the students has generated concerns related to potential health hazards associated with their use. The aim of this study was to assess the prevalence of computer vision syndrome (CVS) & associated non-ocular problems, and to spread awareness about the deleterious effects of various VDTs among the students of SOA Deemed to be University, Odisha, India.

METHODS
A questionnaire-based survey was done among the students of SOA Deemed to be University from September 2018 to March 2019. A total 1141 students participated in the survey. Details on awareness about Computer Vision Syndrome, extent of the VDT use, ocular symptoms and non-ocular health issues related to CVS were recorded. Also, the students were given a brief idea about the adverse effects of prolonged use of such gadgets and the protective measures to be taken to avoid the problems.

RESULTS
A total of 1141 students, aged between 17 and 25 years, from different educational backgrounds of a university in eastern India were surveyed. The prevalence of symptoms of CVS (one or more) was found to be 87.82%. The most frequently reported symptom was headache (56.79%) followed by watering (43.12%) and eye strain (42.59%). Students who used the video display terminals for more than 2 hours per day experienced CVS more than those who use for less than 2 hours. Along with ocular symptoms various non ocular health problems were also reported. Among them neck pain and drowsiness were frequently reported symptoms. Taking frequent breaks in between was associated with less symptoms of CVS.

CONCLUSIONS
Awareness of CVS among the students is very less. As far as possible, use of video display terminals including the smart phones has to be minimised. Mass awareness should be created especially among the younger population through various means of communication to reduce the risk of such health issues related to these gadgets.
