My child is so young and he rarely sees electronic products. Why is he shortsighted?
believes that many parents’ first reaction when they learn that their children’s myopia is not believed, the second reaction is that there are ways to cure their children’s myopia! Today we will talk about why children are shortsighted.
As we all know, my country is a big country with myopia, and myopia is getting younger and younger. Regarding the causes of myopia, it is still not completely clear. Most scholars believe that myopia is related to many factors, including genetic factors, environmental factors, and bad eye habits.
1, genetic factors
A large number of investigations have shown that myopia has a certain degree of heredity. If both or one of the parents is nearsighted, the child's possibility of myopia will increase.
2, environmental factors
long-term use of eyes at close range can lead to an increase in the incidence of myopia, which is also the main reason for the high incidence of myopia in adolescents in my country. In addition, poor lighting, too small or illegible reading, long continuous reading time, lack of outdoor activities, improper sitting posture and other factors will promote the occurrence and development of myopia.
3, predisposing factors
children often like to stare at the computer or TV to watch cartoons and other programs, this behavior is very easy to cause visual fatigue and damage eyesight.
Children generally like to eat sweets and drink carbonated drinks, and these foods contain a lot of sugar. The metabolism of sugar in the human body requires a lot of vitamin B1, and sugar will reduce the calcium content in the body, and calcium is the "protector" of eye tissue The lack of calcium in the body will not only reduce the elasticity of the retina of the eye, increase the pressure in the lens, and elongate the anterior and posterior diameter of the eyeball, but also cause degenerative diseases of the cornea and ciliary muscle, thereby weakening the elasticity of the eyeball wall and promoting myopia.
Therefore, it is recommended that parents must pay attention to the children's eye-using habits, let the children insist on doing eye exercises, and look into the distance for a while after reading a book, and avoid using their eyes at close range for a long time. In addition, it is emphasized that once the child is diagnosed with myopia, he must immediately get glasses, and don't let your wait to ruin the child's eyes!
