Question

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are near-sighted can only see things that are very close to their eyes. Everything else seems unclear. Many people who do a lot of work, such as writing, reading and sewing become near-sighted.

Then people who are far-sighted endure just the opposite problem. They can see things that are far away, but they have difficulty in 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. They have what is called astigmatism（散光）. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts（白內(nèi)障）. Long ago these people often became blind. Now however, it is possible to operate on the cataracts and remove then.

Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle（角度）. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
