I have mild myopia. Eye exercises can help relieve eye fatigue but they did nothing in helping improve my eyesight. I have a good suggestion for you. It is from my personal experience. I have spent one month in the countryside. I can't wear glasses at that time because my grandma will scold me every time she saw me wearing a pair of glasses. She was quite wired. But everyone in the family must respect her. So I couldn't watch TV because my vision was blurry. And my grandma said that you couldn't sit in front of the TV, it was bad to your eyesight. Oh, my god! I want to get rid of her immediately. So I spent the rest of the days, say about nearly one month, in the field. But later I found that my eyesight improved. It is amazing. But it works. So I think spend less time in front to computer or TV is good for our eyes. You can spend more time in the outside.
