More and more students become short

More and more students become short-sighted now. There are some reasons. Some students often spend lots of time playing computer games. Some keep their eyes too close to the books while they are reading. If students are short-sighted, they will have much trouble in life and study. First, without glasses, they are not able to see the blackboard and take notes in class. Second, it is not convenient for them to swim with glasses. I strongly suggest that students should take action to protect their eyes. First, it is a good idea to take a break or do eye exercise after reading for a long time. What’s more, we shouldn’t spend too much time in front of the computer or TV. In short, eyes are such important parts of our body that we should do our best to keep them healthy.
