      It is reported that 300 million people in China have eyesight (视力) trouble. ①More and more parents

hope to save their children's eyesight with medicine, or by correcting the ways that children read and sit.

But in fact, one should start with the exercise on one's feet. Here are three ways to save eyes: 

      First, don't tie your shoes too closely. Try wearing comfortable and soft socks or walking without

socks and shoes at home. While you are traveling, ②try wearing cloth shoes in order to improve blood

circulation. (循环)

      Second, walking on tiptoes is good for one's eyesight. It can fight against eyesight trouble. Numbers

show that most of ballet (芭蕾舞) performers' eyesight is better.

      Third, rope skipping (跳绳) can also be good for one's eyesight. While skipping rope, one has to

move quickly, making both the brain and the eyes excited. It may also help make one grow taller.

      Besides foot exercises, it is good to pull one's ears. Pulling the ears 20 times quickly is also a great

way. It can keep one's eyes healthy.
