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.

“How can I learn English well?” This is a question many students ask. In my opinion, the most effective way is to learn lessons by heart. If you can recite the text and write it out, you’ve learned it fairly well. And if you can tell, in your own words, what the lesson says you’re a very successful learner indeed. Your English will be quite perfect.
This is a difficult task. However, if you try to learn by heart only part of each lesson, you’ll find it not half so hard as you might have thought.
Learning this way, you will make rapid progress. Of course, writing is also necessary. It helps you a lot on our way to success in English.
Equally important is to feel the language. You should be able to laugh at jokes and be shocked at bad news. When using English, try to forget your mother tongue. Instead of helping you, your own language gets in your way. So, never try to see English through translation.
