Have you ever experienced that your eyes are very dry, fatigue and blurred when you face to a computer for a long time? Those are some symptoms of computer vision syndrome (CVS).CVS is a temporary condition resulting from focusing the eyes on a computer display for protracted, uninterrupted periods of time. These include headaches, blurred vision, neck pain, fatigue, eye strain, dry, irritated eyes, double vision, polyopia, and difficulty refocusing the eyes. These 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).
Facing to these problems, what can you do? If you just have these symptoms for a short time, a comprehensive eye test is necessary to make sure the exact trouble and update eyeglass prescription. If your glasses are latest, you are still troubled during computer work. The best choice is to consider buying a pair of professional computer glasses. These special-purpose glasses are prescribed specifically to reduce eye strain and give you the most comfortable vision possible at your computer.
Computer glasses are different from regular eyeglasses or reading glasses in a number of ways to optimize your eyesight when viewing your computer screen. Computer screens usually are positioned 20 to 26 inches from the user's eyes. This is considered the intermediate zone of vision closer than driving ("distance") vision, but farther away than reading ("near") vision.
Though they sometimes are called "computer reading glasses," it's best to call eyewear designed specifically for computer use "computer glasses" or "computer eyeglasses" to distinguish them from conventional reading glasses. Computer glasses put the optimum lens power for viewing your computer screen right where you need it for a clear, wide field of view without the need for excessive focusing effort or unhealthful postures.
