A survey shows that many students have become shortsighted at a very young age. At present, about 70% of the students are shortsighted. Here are some main causes. Some students may not have enough sleep. And some spend much time reading or doing their homework without a rest. Others even watch TV or use computers for a long time.

In order to have good eyesight, we should do eye exercises every day. We can try to do more sports in our spare time. We also should have the good habit of using our eyes.

I think all of us should try our best to protect our eyes.
