Nowadays, there are more and more students becoming short-sighted. Some students get short-sightedness when they are little. There are fifteen students wearing glasses in my class. Being short-sighted is common among students, even in primary school. That is too serious. Therefore, we should protect our eyes carefully. When we are reading and writing, we should keep a standard posture. Besides, we should not watch TV or play computer for too long. They are bad for our eyes. And, we should do eyes exercises regularly. A good rest is also important to our eyes. In all, eyes are the windows of our mind. We should keep it healthy.
