Many children's abnormal eyesight is often caused by bad eye habits, such as reading books in rickety carriages, reading books in small fonts every day, or studying at a desk for a long time without rest. These are very common bad eye habits. Teach children three "ones" and control the distance between their eyes: hit the chest from the table; Eyes one foot away from the book (that is, 33 cm); Reach one inch to the tip of the pen.

Second, avoid children using their eyes for a long time.

Generally, the time of each class in primary schools is 40 minutes. As a standard, children should use their eyes continuously for no more than 40 minutes and rest every 40 minutes 10~20 minutes. When resting, you should leave your seat and exercise your bones and muscles. If possible, it is best to let your eyes look at the distant green scenery, so that the ciliary muscles in your eyes can relax and your eyes can really rest.

Third, exercise properly and do eye exercises.

Because you can't go out and do outdoor activities, you can also do simple sports at home, such as radio gymnastics and stretching. Don't forget to exercise your eyes. Eye exercises can improve blood circulation around the eyes and relieve visual fatigue. Suggest twice a day. Please wash your hands and face before doing exercises.

Fourth, ensure the balance of children's daily diet.

Vitamin E has antioxidant effect, can inhibit lipid peroxidation in lens, and has auxiliary effect on preventing eye diseases. Parents can let their babies eat foods rich in vitamin E, such as bananas and nuts. In addition, adequate sleep is also the key to promoting children's vision development. Parents should bring their children into the good habit of going to bed early and getting up early, and minors should sleep for 8 hours.

In addition, parents need to pay attention to the development of their children's vision in time. They can use the twisted angle vision screening system to check their vision regularly and adjust their eye habits in time.
