Eye Facts

There are many commonly held beliefs about eyesight that are not proven facts. For example, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure（结构）of eyes is changed by wearing glasses at young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of sight if they have glasses unsuitable for their eyes.

We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in weak light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not damage eyesight in the long term.

Another myth about eyes is that they can be replaced, or transplanted from one person to another. There are close to one million nerve fibers（神经纤维）that connect the eyeball to the brain; as of yet, it is impossible to connect them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, someday a full transplant may be possible!
