Look around your class. How many of your classmates wear a pair of glasses?
About 60% of Chinese students had shortsightedness(近视）in 2013. If you find you can't see things clearly, the first thing you should do is to go to the doctor and find out if you have shortsightedness. If you really have shortsightedness, you need right glasses to see things clearly. Wearing glasses is helpful to make your eyes relaxed and slow down the progression(进展）of shortsightedness.
On the other hand, your habit of using your eyes is also important. For example, doing eye exercises at school, spending more time outdoors and looking out of the window.
But life becomes easier for people with glasses. Shortsighted people can wear sunglasses. Some shops including(包括）online shops also sell special glasses for shortsighted people to play sports. For example, with special swimming glasses, shortsighted people can see clearly when swimming. Maybe one day shortsighted people can have special 3-D glasses for TV and movies.
