Working at a computer for long periods of time every day can cause a form of eye strain, which can be characterized by blurry or double vision, a feeling of dryness or soreness in the eyes, and neck or back strain. I recommend discussing this with your eye doctor. However, there is no evidence that this kind of eye strain leads to permanent damage to your eyes themselves. In other words, with rest, your vision will return to normal and your symptoms will improve. So, from one point of view, you don't need to be worried overly much about long term consequences of your computer work on your eyes. At the same time, it is no fun to be suffering from these kinds of symptoms on a regular basis! By far the most common factor contributing to eye strain would be uncorrected vision. Therefore, I would definitely advise that you go to see your eye doctor at your earliest convenience. If they find that you would benefit from vision correction with either glasses or contact lenses, you will almost certainly notice an immediate improvement in your eye strain symptoms. Again, these are not "special" contacts or glasses per se, just making sure that your eyesight is as good as it can be to resist the fatiguing effects of computer work.
Many people assume increased computer use is the source of complaints of eye fatigue and discomfort. But extensive testing in government and private laboratories has not produced scientific evidence that computer monitors will harm your eyes. Research has established that computer monitors emit little or no hazardous radiation, such as x-ray, or non-ionizing radiation, such as ultraviolet rays.While computers have no known harmful effects on eyesight, computer users do often complain of eye related symptoms such as eyestrain, headaches, fatigue, dry eyes, and difficulty focusing, These symptoms however are caused not by the computer screen itself but rather by the conditions surrounding the computer screen, such as poor lighting or improper placement of computer equipment and computer furniture. In some instances, a pre-existing eye problem may be the cause.
Nowadays, almost all people can not lay a day without computers. So the eye fatigue and discomfort are most common among computer user. However, there is not evidence that show computer screen will hurt their eyes. Actually, the eye fatigue and discomfort are not caused by the computer screen but a prolonged eye use.
