Incidence of Dry Eyes Amongst The Computer Users
Keywords:CVS, Dry Eye, Glare, VDT, Ocular Discomfort, Ocular Fatigue
Objective: The Study was aimed at finding the incidence and prevention of computers vision syndrome(CVS) particularly “dry eye” in regular computer users.
Study design: Observational, cross-sectional study
Place and duration of study: It was conducted at Combined Military hospital Lahore, from Dec 2014 to Nov 2015.
Methodology: A "questionnaire proforma" was prepared and distributed to the willing candidates. It was based on symptoms of dry eye, sensitivity of eyes to various environmental conditions, history of medications contributing to dry eye, working hours on computers etc. The visual effects of various display characteristics such as lighting, glare, display quality, refresh rates, and radiation are also briefly discussed.
Results: Out of 290 regular computer users, 88 (30.3%) were found to have dry eye problem. Conclusion Although the computers vision syndrome is associated with a variety of ocular symptoms related to computer use including eyestrain, tired eyes, irritation, redness, blurred/double vision, headache and shoulder pain, this article was primarily focused on "dry eye" the major contributor to computer vision syndrome symptoms. Management requires a multidirectional approach combining ocular therapy with adjustment of the workstation.
Conclusion: Proper lighting, anti-glare filters, ergonomic positioning of computer monitor and regular work breaks may help improve visual comfort. Lubricating eye drops and special computer glasses help relieve ocular surface-related symptoms. A lot more work needs to be done to specifically define the processes that cause dry eye in computer vision syndrome and to develop and improve effective treatments that successfully address these causes.
