Category 4 children are the most likely to get 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; Myopia above 600 degrees is almost related to heredity.

children born prematurely

and

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.

children with less sleep time

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

the genetic degree of myopia in children whose parents are myopia increases with the deepening of the 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.

children with low birth weight

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.
