Computer Vision Syndrome affects 75% of the people who work on computers, most markedly those who work more than 3 to 4 hours with computers. This includes all professions that use computers (IT, BPO, Accounting, banking, front office) students and children who • Work at the computer for more than 3 hours a day • Have strain at computer work. • Experience any or all of the symptoms of CVS stated • Experience stressful situations associated with work

CVS can occur in any age group but children are found to report less of symptoms. This does not indicate that children are not prone to CVS, but that they continue to strain the visual system and the condition is overlooked to a greater extent than adults. The visual system in teenagers is well adapted to near tasks, but the strain due to change in image quality, glare, lighting and absence of breaks between computer use, associated with muscle imbalances and power changes need a closer watch as it is the changing phase of physical development and no chances can be taken.

CVS is often different from other typical eye problems. The usual ophthalmic examination focuses more on distance vision (6 m and beyond) and near vision (35 to 40 cm), whereas the computer professionals have a unique working distances with respect to the monitor, keyboard, mouse, etc. Due to this difference in working distance, the usual examination does not completely address the actual environmental conditions. The Computer Vision Clinic, however, is specially designed to address the varied needs of the individual computer user.

The best way to treat CVS is to identify the conditions that have contributed to the symptoms and address them. The earlier the condition is detected the more it acts as a preventive measure. Ideal ocular status and proper ergonomics both visual and environmental could keep the condition under check. Management is minimal and modifications become the answer. The frequency of follow-up is also reduced as the condition is easily reversible. A delay in detection means signs which have set in more deeply and a greater effort is required from the clinician and the computer user to first program a schedule to rectify the damages to the maximum possible extent and then work towards reducing the source of repetitive stress or altering it favourably without affecting work or the eyes. In this situation frequent follow-ups are essential to ensure proper management of the ocular condition and asses the effect of the work related changes on the eye. The adage “Prevention is better than cure” seems to best fit CVS and eye care.

Yes. CVS can be prevented. The first step towards prevention is to be aware. CVS sets in often due to the assumption that mild discomfort is inevitable at computer work. The early signs are overlooked and this gives way to stronger problems. Awareness of what is ideal for the eye and visual system to work comfortably is thus the first step. The web is a great source of information for this awareness. But improper use of the information and poor understanding of the intricate visual process can often lead to more discomfort than we could tell. This is where professional counsel comes in handy to educate ourselves on the best ways to utilize our ocular and ergonomic resources with the least effect on the human body.
