Eyes are important for everyone. Not taken good care of, eyes would suffer from kinds of diseases and good eyesight can not be guaranteed. There is a saying about “glasses races” on many of the health forums on the Internet, if we use computers for a long term, we should better wear glasses with low-degree than usual degree or not wear glasses, it will help us protect our eyesight, is this kind of argument justified or not?
Medical experts said: In order to stay more safely before the computer screen, we should wear the glasses with normal degree. It’s wrong for us to wear eyeglasses in a low degree or without the glasses. For some patients with high myopia, not wearing glasses in front of the computer tends to damage the eye more. For some guys with high myopia, the harm to their eyes tends to be greater if not wearing glasses in the front of computer. Because the normal eyes have a natural function “adjustment efforts” in normal circumstances, which can let us see close objects clearly, the eye can self-regulate, so we can see objects more clearly. This regulation is very natural. So when looking at near objects, they have the same effect whether we wear glasses or not. But for some patients with high myopia, if taking off the glasses, the vision might be blurred. Although they see something unclearly, they will try their best to see, and it will not be good for their eyes in such a state.
It is reminded that the eye protection is not achieved by absolutely taking off glasses in front of the computer; the better way for us to protect our eyes is that we should pay attention to the habits of using the eyes. First, we should pay attention to the length of time , we should close our eyes and rest for a few minutes when looking at the computer for each about an hour. Secondly, when we see the computer screen for a long time, we should try to force ourselves to blink for more times, so that the eyes can be in enough rest. Thirdly, we should keep the distance between eyes and screen at about 60 centimeters, and our sight should be 10~15 degrees below the screen center, Moreover, in exhaustion, we should look at large numbers of green plants, or using some eye drops.
