①Have your parents ever told you any strange things about protecting your eyes? For example, they might have said that you'd go blind from reading in the dark, but you could make up for it by eating a lot of carrots.

②This is just one of the wrong ideas you may have heard of. Below teens has picked out scientific explanations for three mistakes the people often make about eyes. Let's take a look.

③Can eating carrots improve your eyesight? Carrots are rich in Vitamin A, which is necessary for our eyes' general health. Vitamin A helps the eyes to make light into signals, allowing people to see in low light conditions. However, eating more carrots doesn't help you see better. Only a few will help, but a large number of carrots will not give you superhuman eyesight or allow you to get rid of your glasses.

④If your parents have bad eyesight, will you have short eyesight, too? Myopia(近视) can be passed from parents to children. A study found that if both parents are myopia, there's a 33 to 60 percent chance that the child is. For children who have one parent with myopia, the chance is 23 to 40 percent, and it's down to 6 to15 percent for kids with non-myopia parents. So no matter how bad your parents' eyesight is, you still have a chance of having good eyesight.

⑤Is it true that people who are color blind can't see colors? Color blindness doesn't mean that someone can't see colors at all, like a black and white movie. Most commonly, it means that someone has difficulty telling certain colors apart, usually green and red or blue and yellow.

⑥There are different levels of color blindness. Some people cannot tell the difference between colors in dark light, while others have difficulty in any light. In the most serious form of color blindness, everything is seen in shades of gray.
