阅读理解. When we can see well,we do no

阅读理解.
When we can see well,we do not think about our eyes often.It is only when we can not see perfectly
that we come to see how important our eyes are.People who are nearsighted can only see things that are
very close to their eyes.Many people who do a lot of close work,such as writing and reading,become
nearsighted.Then they have to wear glasses in order to see distant things clearly.
People who are farsighted face just the opposite problem.They can see things that are far away,but
they have difficulty reading a book unless they hold it at arm's length.If they want to do much reading,
they must get glasses too.
Other people do not see clearly because their eyes are not exactly the right shape.This,too,can be
corrected by glasses.Some people's eyes become cloudy because of cataracts.Long ago these people
often became blind.Now,however,it is possible to operate on the cataracts and remove them.
When night falls,colors become fainter to the eyes and finally disappear.After your eyes have grown
used to the dark,you can see better if you use the side of your eyes rather than the centers.Sometimes,
after dark,you see a small thing to one side of you,which seems to disappear if you turn your head in its
direction.This is because when you turn your head,you are looking at the thing too directly.Men on guard
duty sometimes think they see something moving to one side of them.When they turn to look straight at it,
they can not see it any more,and they believe they were mistaken.However,this mistake happens because
the center of the eye,which is very sensitive in daylight,is not as sensitive as the sides of the eye after dark.
