Today， I found more and more students wear glasses。 It’s not a good phenomenon because it means more and more students can’t use their eyes in a right way。 After doing a survey， I think there are two reasons to cause near eyesight。

First， there are more and more computer games in the 21st centre， most boys like play them。 Although games are interesting， their eyesight became worse and worse at the same time。 So they had to wear glasses。

Secondly， the students who love reading stories want to read all the time， even sometimes they read their novels until very late and their eyes become very tired。 Their eyes got worse because they didn’t use enough light to read。 Reading is fun， but remembers to use enough light when you read。 In the end， they had to wear glasses， too。

We should take this matter seriously。 Can you imagine that in the future， all the people need glasses to help them see clearly and without glasses， they could see nothing?
