What kind of child is easy to suffer from myopia?

Abstract: the genetic degree of myopia increases with the deepening of degree. Generally speaking, myopia below 300 degrees has little to do with heredity: myopia of 300-600 degrees has a close relationship with heredity; Almost all myopia above 600 degrees is related to heredity., China’s youth myopia tends to be younger. There are more than 5 million blind people, more than 6 million people with low vision and 10 million children with oblique amblyopia. However, the average myopia rate of teenagers is 40%, and the myopia rate of college students is far more than 70%. In particular, the myopia phenomenon of children aged 7 to 9 has increased significantly, and many children begin to have myopia before school age or early age, Parents and friends should pay more attention., Sleep less, easy to suffer from myopia., During the accelerated period of children’s growth and development, especially when they are 7-9 years old and 12-14 years old, if the children’s sleep time is reduced or artificially deprived of sleep time (excessive homework burden), myopia will occur in some children., Low birth weight is prone to myopia., Children who weigh less than 2500 grams at birth are prone to myopia before puberty. This is mainly due to the congenital dysplasia of low birth weight children and the long development of ocular axis caused by adverse factors., Premature children are prone to myopia., Myopia often occurs in children born 2 weeks or more prematurely. The mechanism of myopia in these children is the same as that in low birth weight children., Parents with myopia are prone to myopia.,

Chinese teenagers’ myopia tends to be younger. There are more than 5 million blind people, more than 6 million low vision people and 10 million children with oblique amblyopia in China. However, the average myopia rate of teenagers is 40%, and the myopia rate of college students is far more than 70%. In particular, the myopia phenomenon of children aged 7 to 9 shows an obvious upward trend, and many children begin to have myopia before school age or early age, Parents and friends should pay more attention.

and

sleep less and are prone to myopia.

in the accelerated period of children’s growth and development, especially at the ages of 7-9 and 12-14, if children’s sleep time is reduced or artificially deprived of sleep time (excessive homework burden), myopia will occur in some children.

low birth weight is prone to myopia.

children who weigh less than 2500 grams at birth are prone to myopia before puberty. This is mainly due to the congenital dysplasia of low birth weight children and the long development of ocular axis caused by adverse factors.

premature children are prone to myopia.

children born prematurely for 2 weeks or more often have myopia in childhood. The mechanism of myopia in these children is the same as that in low birth weight children.

parents are myopic and are prone to myopia. The heritability of

and

myopia increased with the deepening of degree. Generally speaking, myopia below 300 degrees has little to do with heredity: myopia of 300-600 degrees has a close relationship with heredity; Myopia above 600 degrees is almost related to heredity.
