     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.
