![]() At present there are no large scale nationally representative studies on the prevalence of CVS among computer office workers from the South Asian region or from the rest of the world. Similar to other countries, the few South Asian studies on CVS prevalence that are currently available in the literature are small scale and based in a single institution. Hence, it is likely that South Asian computer office workers also have a significant prevalence of CVS, with its associated loss of productivity and compromised quality of life. The region has undergone rapid socio-economic development and technological advancement during the last few decades, with resultant increase in computer literacy and usage. India, Pakistan, Bangladesh, Nepal, Sri Lanka, Bhutan and Maldives are the countries of the region. South Asia, commonly known as the Indian sub-continent, is home to almost one-quarter of the world’s population and is comprised of many diverse ethnic, linguistic and religious groups. However, most of the studies on CVS prevalence have been among a limited number of computer workers and usually conducted within a single institution/organization. Other studies estimate that the prevalence of CVS ranges from 75 to 90 % among computer users. In a review on CVS, Thomson indicated that up to 90 % of computer users may experience symptoms related to CVS after prolonged computer usage. Hence, it is likely that CVS will continue to create a significant and growing contribution to reduced productivity at work, whilst also reducing the quality of life of the computer office worker.Įstimates of the prevalence of eye problems associated with VDTs vary enormously, depending on the sample tested, research methods employed and study instrument used. In the twenty first century personal computers are one of the commonest office tools, used in almost all institutions/organizations, for a wide variety of vocational and/or non-vocational purposes. It is estimated that nearly 60 million people suffer from CVS globally, and that a million new cases occur each year. Symptoms of CVS includes dry and irritated eyes, eye strain/fatigue, blurred vision, red eyes, burning eyes, excessive tearing, double vision, headache, light/glare sensitivity, slowness in changing focus and changes in colour perception. It encompasses a group of visual symptoms which crop up from the extended viewing of the video display terminal (VDT), when the demands of the task exceed the abilities of the viewer. “Computer Vision Syndrome” (CVS), is defined by the American Optometric Association as a complex of eye and vision problems related to the activities which stress the near vision and which are experienced in relation to or during the use of computers. ![]()
