Nearsighted makes you wear glasses all the time, and long time later, you will find the glasses are annoy and trouble, you want to get rid of it. I want to tell you that the eyesight will not get better on it's own. Nevertheless, you can take some methods to stop your eye sight worse, pls note it can just stop it gets worse, but you can not make the vision better than before. As usual, when you feel your eyes tired, you can just stop your work and let your eyes have a rest and meantime, you can do some eye exercise. If you really want to make your eye sight better like before, I suggest you take the eye surgery, which will help you get rid of the glasses and your eye sight will be good as before. But you have to take care of your eyes after the surgery.Good Luck.
