Computer brings us much benefit. It conveniences our lives by providing a wide range of information, offering online shopping and so on so forth. However, computer also brings us troubles and harms, especially to eyes. Staring at a computer screen for a too long time would cause eye problems and visual symptoms, for example, most computer users experience eyestrain, blurred vision and headaches, etc.. Therefore, while we are enjoying the benefit brought by computer, we should learn to protect our eyes.
Computer gives out harmful radiations. To prevent them hurting eyes, besides anti-glare screens, computer glasses coated with special coating are recommended. They are especially designed for computer users. Users of them claim that their eyes feel great and less stressed. And at the meantime, those eyeglasses reduce the occurrence of visual problems. They are now preferred choices for people who had to spend too much time in work.
Some other ways to protect eyes include doing eye exercises and having enough rest. Eye exercises would help to relax eye muscles. One would learn from videos down loaded from Internet or learn from eyecare professionals. A simple one is to exercise eyes by looking up, down, left, right, round and repeat 3 times. Next, enough rest for eyes is also important. If you have ever tried to stare at computer screen for several hours a day, you would feel ache on eyes, which indicates that eyes are protesting and asking for rest. Therefore, the suggestion is to shift vision every two hours by observing green trees far or taking a walk. It is a rather effective way to get eyes rested. Even if you've been suffered from some eye or visual problems, don't worry. Keeping the above mentioned method for several weeks, your eyes would recover.
The settings of a computer would also serve as a help in protecting eyes and eyesight. For example, if you have a CRT monitor, a refresh rate of 85Hz instead of 75Hz would minimize the hurt to eyes. The way to set the computer is to click following the instruction: Properties -> Settings -> Advanced -> Monitor. Clean the screen regularly as they attract dust. The computer screen should be slightly below eye level. The expensive solution is to buy an LCD monitor; they are much easier on the eyes.
