With the burden of study increasing,more and more students become short sight.So we asked the eye specialist how to deal with the problem.The specialist suggest that,first,the students should control the reading time.When the students read the book for an hour,they should have a rest or do some exercises to make their eyes relax.Second,they should pay attention to the light.The light should not be too dark or bright.Third,the students should do eye exercise regularly to protect their eyes.Fourth,the students should get plenty of sleep.More sleep means more rest of eyes.We hope those suggestions are useful and can protect your eyesight.
