Computer Vision Syndrome
Computer vision syndrome (CVS) is a temporary condition resulting from focusing the eyes on a computer display for long, uninterrupted periods of time. Some symptoms of CVS include headaches, blurred vision, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, vertigo/dizziness and difficulty refocusing the eyes. These symptoms can be further aggravated by improper lighting conditions (i.e. glare or bright overhead lighting) or air moving past the eyes (e.g. overhead vents, direct exposure to air from a fan). Asthenopic symptoms (mentioned above) 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. We recommend the usage of Anti-Glare Lenses for spectacles along with the "20-20-20 rule" : every 20 minutes, focus the eyes on an object 20 feet (6 meters) away for 20 seconds.
