    When Li Ming was a primary school student,he had to wearing glasses.Now he is becoming more and more near-sighted.The more he reads,the thick his glasses become.As far as I know it,more and more students have poor eyesight in China.

    Why did so many students have to wear glasses?Sometimes they read in strong sunlight and sometimes they read in places which the light is too poor.Some watch TV too many.Some even have a bad habit of reading in bed.As result,their eyesight becomes poorer and poorer.
