Passage One
段落一
There are many commonly-held beliefs about eye glasses and eyesight that are not proven facts.
有許多未被證實的關于眼鏡和視力的觀點。
For instance, some people believe that wearing glasses too soon weakens the eyes.
例如，有些人認為過早的戴眼鏡會使視力變差。
But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age.
但是沒有證據表明眼睛結構的改變是由過早的戴眼鏡而造成的。
Wearing the wrong glasses, however, can prove harmful.
但是戴錯了眼鏡對人是有害的。
Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes.
研究表明這對成年人沒有危險，但孩子們戴了不合適的眼鏡會降低視力。
We have all heard some of the common myths about how eyesight gets bad.
我們聽到過一些常見的誤區是關于視力如何變壞的。
Most people believe that reading in dim light causes poor eyesight, but that is untrue.
大多數人認為在昏暗的燈光下閱讀會導致視力不佳，但這不是真的。
Too little light makes the eyes work harder, so they do get tired and strained.
光線過少容易使眼睛使用過度，并感到疲倦、不舒服。
Eyestrain also results from reading a lot, reading in bed, and watching too much television.
眼睛的疲勞來源于過度閱讀、在床上看書和長時間看電視。
However, although eye strain may cause some pain or headaches, it does not permanently damage eyesight.
不過，雖然眼睛疲勞可能會引起一些疼痛或頭痛，但它不是永久性損害視力。
Another myth about eyes is that they can be replaced, or transferred from one person to another.
另外一個誤區就是眼球能被替換或從一個人身上移植到另一個人身上。
There are close to one million nerve fibers that connect the eyeball to the brain, as of yet it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced.
有將近一百萬條神經纖維把眼球和大腦相連接。幾乎無法完全的將眼球與新主人連結在一起。只有某些部分可以被取代。
But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible.
但是如果我們掃除誤區，了解更多眼睛的知識，也許完整的眼球移植就有可能實現了。
