Passage One
段落一
There are many commonly-held beliefs about eye glasses and eyesight that are not proven facts.
有许多未被证实的关于眼镜和视力的观点。
For instance, some people believe that wearing glasses too soon weakens the eyes.
例如，有些人认为过早的戴眼镜会使视力变差。
But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age.
但是没有证据表明眼睛结构的改变是由过早的戴眼镜而造成的。
Wearing the wrong glasses, however, can prove harmful.
但是戴错了眼镜对人是有害的。
Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes.
研究表明这对成年人没有危险，但孩子们戴了不合适的眼镜会降低视力。
We have all heard some of the common myths about how eyesight gets bad.
我们听到过一些常见的误区是关于视力如何变坏的。
Most people believe that reading in dim light causes poor eyesight, but that is untrue.
大多数人认为在昏暗的灯光下阅读会导致视力不佳，但这不是真的。
Too little light makes the eyes work harder, so they do get tired and strained.
光线过少容易使眼睛使用过度，并感到疲倦、不舒服。
Eyestrain also results from reading a lot, reading in bed, and watching too much television.
眼睛的疲劳来源于过度阅读、在床上看书和长时间看电视。
However, although eye strain may cause some pain or headaches, it does not permanently damage eyesight.
不过，虽然眼睛疲劳可能会引起一些疼痛或头痛，但它不是永久性损害视力。
Another myth about eyes is that they can be replaced, or transferred from one person to another.
另外一个误区就是眼球能被替换或从一个人身上移植到另一个人身上。
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.
有将近一百万条神经纤维把眼球和大脑相连接。几乎无法完全的将眼球与新主人连结在一起。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.
但是如果我们扫除误区，了解更多眼睛的知识，也许完整的眼球移植就有可能实现了。
