Abstract: when watching TV and computer for more than two hours every day, the distance between eyes and TV is less than 3m, and the distance between reading for a long time is less than 30cm, most children will have visual fatigue, and some of them will have myopia., Children who sleep less are prone to myopia. During the rapid growth and development period of children, especially when they are 7 ~ 9 years old and 12 ~ 14 years old, if they sleep less, they will cause myopia in some children., Low birth weight. Children with a birth weight of less than 2000g are prone to myopia in adolescence due to their congenital dysplasia and acquired adverse factors., Premature infants. Especially for children born 2 weeks or more prematurely, myopia often occurs in childhood., Parents are myopic, and their children are prone to myopia. The degree of heredity increases with the deepening of myopia., When watching TV and computer for more than two hours every day, the distance between eyes and TV is less than 3m, and the distance between reading for a long time is less than 30cm, most children will have visual fatigue, and some of them will have myopia., Partial eclipse. Partial eclipse can lead to nutritional deficiency in children. Calcium deficiency directly affects the sensitivity of the eyes to light. Calcium deficiency can increase the excitability of nerve and muscle cells, often in a state of tension. Excessive tension of ciliary muscle will directly compress the eyeball. When scleral tissue is calcium deficient, its elasticity and firmness will decrease, the hardness of scleral wall will weaken, and the ocular axis will prolong., Therefore, children with low birth weight, premature infants and high myopia of their parents should go to the hospital for examination as soon as possible. Usually urge children to develop good eye habits, pay attention to eye hygiene, avoid long-time and close eye use, and limit the time of watching TV < half an hour / day. Do not be partial to food, eat less sweets, eat more foods rich in vitamins, protein and calcium, strengthen physical exercise, enhance physique and ensure adequate sleep. Children diagnosed with true myopia should wear glasses correctly and have regular re examination to control the deepening of myopia as far as possible.,
children who sleep less are prone to myopia. During the rapid growth and development period of children, especially when they are 7 ~ 9 years old and 12 ~ 14 years old, if they sleep less, they will cause myopia in some children.
and
have low birth weight. Children with a birth weight of less than 2000 grams are mainly due to their congenital dysplasia and acquired adverse factors, resulting in long ocular axis development, and are prone to myopia in adolescence.
premature infants. Especially in children born 2 weeks or more prematurely, myopia often occurs in childhood. The parents of

are myopic, and their children are prone to myopia. The degree of heredity increased with the deepening of myopia.
when watching TV and computer for more than two hours every day, the distance between eyes and TV is less than 3m, and the distance between eyes and TV is less than 30cm for a long time, most children will have visual fatigue, and some of them will have myopia.
