Computer vision syndrome:
Computer Vision Syndrome or CVS is a cause of concern with increased use of computer by general population. 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.

Computer vision syndrome (CVS) is excessive strain on eyes which is caused by working in front of computer monitor or computer screen for protracted, uninterrupted periods of time. When you concentrate on the computer monitor, the eye tends to blink less, this is an involuntary action and it results in drying up of the tears which are natural lubricant lining the eye’s surface. Any allergies or infections that may effect the production of tears of the eyes can aggravate the condition. This condition may become worse during seasonal change or exposure to dust and pollution. . The symptoms can be further aggravated by improper lighting conditions (ie. bright overhead lighting or glare) or air moving past the eyes (e.g. overhead vents, direct air from a fan).

Symptoms Of Computer Vision Syndrome (CVS)
  • Strain on the vision.
  • Feeling tiredness and heaviness in the eyes.
  • Discharge and watery eyes.
  • Blurring of vision.
  • Feeling itchiness and pain in the eyes.
  • Feeling irritation and redness in the eyes.
  • Difficult to focus on distant objects i.e. refocusing of eyes.
  • experience eye twitching
  • neck pain
  • fatigue
  • polyopia
  • double vision etc

Dry eye is a major symptom that is targeted in the therapy of CVS. The use of artificial-tear solutions can reduce the effects of dry eye in CVS. The 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. 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. The "20-20-20 rule" is every 20 minutes, focus the eyes on an object 20 feet (6 meters) away for 20 seconds. Otherwise, the patient is advised to close his /her eye (which has a similar effect) for 20 seconds, at least every half hour. Exercise your eyes in simple and easy manner by rotating them in clockwise and anti clockwise direction few times. Move your eyes up ways and down ways few times. These exercises would relieve your eyes off stress Wearing small plus powered eyeglasses helps such patients regain their ability to focus on near objects.
