The cause of the formation of children's myopia, most parents did not expect!
Why there are more and more myopic children, many parents will think that the child's learning pressure, incorrect eye posture or too much contact with electronic products, etc., in fact, there are many reasons for myopia in children, let us learn more about the causes of myopia, help children better prevent myopia.
Parental inheritance
Children with one or both parents who are highly myopic are at higher risk than the average child. Experts say that genetic factors play an important role in the occurrence and development of myopia. If both husband and wife are highly myopic, the chance of a child being myopic is as high as 80%.
Insufficient sleep
Children who sleep less are prone to myopia. During the rapid growth and development of children, especially 7-9 years old and 12-14 years old, if there is little sleep time, it will cause myopia in some children.
Lack of adequate outdoor exercise time
Studies have shown that increasing outdoor activity time has a clear protective effect on the occurrence and development of myopia in adolescents. Therefore, parents must take their children to the outdoors. The more outdoor activities there are, the less likely it is to develop myopia. For children who want to prevent myopia, outdoor activity time is at least 2 hours per day, and 3 hours is better.
Use the eye environment
Reading in places where the light is too bright, too dark, glare, and reflective will have a detrimental effect on vision. If the light is too strong, it will cause strong reflections, irritate the eyes, make the eyes uncomfortable, and it is difficult to see the font; the light is too weak, the writing illumination is insufficient, the eyes cannot clearly see the font, the head will move forward, close to the book, the above two conditions will lead to eye fatigue, over-regulation or spasms and the formation of myopia.
Unbalanced diet
The child's eye development is actually the same as the principle of physical development, eye development also needs calcium, chromium and other elements, if the child is picky, unbalanced diet, it is easy to cause his myopia.
Lutein is the key element of eye development, and the human body can not be synthesized by itself, reasonable daily supplementation of lutein is conducive to the healthy development of children's vision.
Too much exposure to electronic products too early
The widespread use of computers, televisions and mobile phones is one of the important reasons for the high incidence of myopia in children and the trend of younger age. Harmful high-energy blue light emitted from electronic product screens can accelerate the decline of retinal cells, cause eye fatigue, and even become a myopia and more serious eye disease
