Methods to Avoid Eyestrain

Eyestrain is the most common weariness that most computer users all over the world experience. A number of symptoms associated with eyestrain have been experienced and proved worldwide. Let's have a look at some of the symptoms related to vision here: ** Visual fatigue ** Blurred or double vision ** Burning and watering eyes ** Headaches and frequent changes in prescription glasses This is now called under the nickname, computer vision syndrome or which the American Optometric Association defines, C.V.S as "A complex of eye and vision problems which are experienced during and related to computer use". There is a basic problem with the prolonged viewing of computer screens. The nature of screen characters and images necessitates subtle but continual refocusing. If one has to regularly switch the attention between a close screen and more distant workspace objects things become more complicated. C.V.S results from this change in dynamics. Another cause is that the average person blinks approximately 4 times per minute, far less than the natural rate of 22 blinks per minute. This lower blink rate causes eye moisture to evaporate, resulting in a "dry eye" condition. The symptoms of dry eye are sensations such as itching, burning, blurring, heavy eyelids, fatigue and double vision. There is no evidence yet that computer work causes permanent eye damage. But the temporary discomfort that may occur can reduce productivity, cause lost work time, and reduce job satisfaction and self-confidence of the user. In most cases eyestrain results from visual fatigue or glare from bright windows or strong light sources, light reflecting off the display screen, or poor display screen contrast. Some basic actions you can take to avoid eyestrain are assuring your blinking more often than normal, reducing glare by altering your workspace lighting, adjusting contract and brightness on your monitor for clarity and comfort, adjust the height of the monitor to level the top with your line of sight, and maintain good workspace ergonomics to eliminate any straining. There are may steps to relieve this common problem and I have only listed a few examples.
