It is reported that 300 million people in China have eyesight trouble. More 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, try 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) 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.
