Writing:
In recent years more and more school students have become short-sighted. It is reported that as high as 30 to 50 percent of the students wear glasses and the numbers are still increasing. We should pay great attention to this problem.
As we know, there are some different causes for short-sightedness. Students always have so much homework to do every day that they are busy doing their homework day and night. Besides, some of them watch TV too much, sitting right in front of the TV set for hours, without resting their eyes. Others play video games or chat online for a long time. All these do harm to their eyes.
As students ,we must try our best to take care of our eyes. Therefore we should form a good habit of reading, do eyesight exercises regularly and never wear out our eyes.
