Can eating carrots improve your eyesight?
吃胡萝卜能改善视力吗？

Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain.
胡萝卜富含维生素A，有助于眼睛将光线转化为大脑可以理解的信息。

This allows people to see in darker places.
这使得人们能在较暗的地方看得更清楚。

However, eating more carrots won't help you see better.
然而，吃更多的胡萝卜并不会让你视力更好。

A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.
适量的胡萝卜有帮助，但吃大量胡萝卜不会让你获得超凡的视力。

If your parents have bad eyesight, will you have bad eyesight, too?
如果你的父母视力不好，你也会视力不好吗？

Myopia (近视) can be passed from parents to children.
近视可以从父母遗传给子女。

A study by the American Optometric Association found that if both parents are myopic, there's a 33 to 60 percent chance that their child will be.
美国验光学协会的一项研究发现，如果父母双方都是近视，子女近视的概率为33%至60%。

For children who have one parent with myopia, the chance is 23 to 40 percent, and it's down to 6 to 15 percent for kids with non-myopic parents.
如果只有一方父母近视，子女的概率为23%至40%；而如果父母都不是近视，子女的概率降至6%至15%。

So if your eyesight is bad, your children might still have good vision.
所以，如果你的视力不好，你的孩子可能还是会有好的视力。
