It seems that people with myopia are not suitable to play sports for long coz they will feel uncomfortable shortly after beginning. I also heard that there are several exercises to help reduce myopia but I just don' t know how to do them. You might as well search them online and follow the video. I know how bad it feels to live with myopia so you had better not get that. It makes me very hard to focus on a lot of things. If you are still not sure that whether you get myopia or not, you may go to have an eye exam. A simple eye exam can just test most of your eye problems.
