Computer vision syndrome (CVS) is a temporary condition resulting from focusing the eyes on a computer display for protracted, uninterrupted periods of time.
Some symptoms of CVS include headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, polyopia, and difficulty refocusing the eyes. These symptoms can be further aggravated by improper lighting conditions (i.e. glare [1] or bright overhead lighting) or air moving past the eyes (e.g. overhead vents, direct air from a fan).
According to the National Institute of Occupational Safety and Health, computer vision syndrome affects some 90% of the people who spend three hours or more a day at a computer.
Dry eye is a major symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.
Asthenopic symptoms in the eye are responsible for much of the morbidity in CVS. Proper rest to the eye and its muscles is recommended to relieve the associated eye strain. Various catch-phrases have been used to spread awareness about giving rest to the eyes while working on computers. A routinely recommended approach is to consciously blink the eyes every now and then (this helps replenish the tear film) and to look
out the window to a distant object or to the sky—doing so provides rest to the ciliary muscles. One of the catch phrases is the "20-20-20 rule": [citation needed] every 20 minutes, focus the eyes on an object 20 feet (6 meters) away for 20 seconds. This basically gives a convenient distance and time frame for a person to follow the advice from the optometrist and ophthalmologist. Otherwise, the patient is advised to close his/her eyes (which has a similar effect) for 20 seconds, at least every half hour.
Decreased focusing capability is mitigated by wearing a small plus-powered (+1.00 to +1.50) over-the-counter pair of eyeglasses. Wearing these eyeglasses helps such patients regain their ability to focus on near objects. People who are engaged in other occupations—such as tailors engaged in embroidery—can experience similar symptoms and can be helped by these glasses.

Watch This .... Combat Computer Vision Syndrome (CVS).
Children and teenagers (ages 8-18) are spending more than 7.5 hours a day consuming electronic media which can cause blurry vision, dry and irritated eyes, headaches, neck pain and back pain. As children grow up in a digital world full of personal computers, hand-held video games, smartphones and e-readers at their disposal, they are increasing their risk of computer vision syndrome (CVS) or digital eye strain.
Millions Of People Likely Suffering From Computer Vision Syndrome.
Computer Vision Syndrome is a medical condition associated with our addiction to digital devices -- from computers to smart phones, hand-held video games and e-books.
Computer Vision Syndrome.
Those who use computers daily could suffer from computer vision syndrome. Individual vision problems, poor work space set-up and improper work habits can lead to symptoms like fatigue, light sensitivity, neck and/or backache, eyestrain, and dry eye.
