Abstract: the occurrence and development of myopia are closely related to personal constitution. Current research data and statistical data show that if one of the parents has high myopia, the penetrance of myopia inheritance in their offspring is 50%. If both parents are high myopia, the penetrance of myopia inheritance in their offspring is 80%., In the process of normal eye development, the development of various “parts” of the eye should be coordinated and balanced with each other. If they match well, our eyes will develop into emmetropia, which is the emmetropia process of the eye. If the parameters of any one of the “parts” are abnormal, the other “parts” parameters cannot be compensated effectively, Will cause ametropia (myopia, hyperopia, astigmatism). The pathogenic factors of myopia. The current research has confirmed that the interaction of genetic factors and environmental factors is an important cause of myopia. The occurrence and development of myopia are closely related to personal constitution. The current research data and statistical data show that one of the parents has high myopia, and the offspring have high myopia inheritance The penetrance rate is 50%. If both parents are highly myopic, the penetrance rate of myopia inheritance in their offspring is 80%., Early and excessive close eye use, such as improper posture in homework, too long reading time, playing mobile phones, computers, game consoles, practicing piano, playing small toys, etc., resulting in excessive visual proximity load, which is the main environmental factor inducing myopia., Conclusion of myopia etiology. The best conclusion of myopia etiology is that in the period when children’s eyes develop the fastest and most unstable, the poor eye environment increases the penetrance and expression of myopia genes. Therefore, it eventually leads to myopia. Close overuse is the catalyst of myopia gene., People with myopia genetic constitution will be more affected by bad eye habits. Not only the early onset age, but also the rapid progress of myopia, the probability of developing into high myopia will increase greatly.,

pathogenic factors of myopia
current research has confirmed that the interaction between genetic factors and environmental factors is an important cause of myopia.
The occurrence and development of myopia are closely related to personal constitution. The current research data and statistical data show that if one of the parents has high myopia, the penetrance of myopia inheritance in their offspring is 50%. If both parents are high myopia, the penetrance of myopia inheritance in their offspring is 80%.
and
use their eyes too early and too much at close range, such as improper posture in homework, too long reading time, playing mobile phones, computers, game consoles, practicing piano, playing small toys, etc., resulting in excessive near vision load, which is the main environmental factor inducing myopia.
myopia etiology conclusion the best conclusion of
myopia etiology is that in the period of the fastest and most unstable development of children’s eyes, the adverse eye environment increases the penetrance and expression of myopia genes. Therefore, it eventually leads to myopia. Close overuse is the catalyst of myopia gene.
people with myopia genetic constitution will be more obviously affected by bad eye habits. Not only the early age of onset, but also the rapid progress of myopia, the probability of developing into high myopia will increase greatly.
myopia prevention and control
myopia prevention should be started from an early age. After the child is born, it is necessary to develop good eye habits. Don’t read too much, play with mobile phones and computers too early.
and
go to regular and professional ophthalmic institutions or ophthalmic hospitals for physical examination after the age of 3. After getting myopia, myopia will deepen with age. 6 ~ 16 years old is the period of the fastest physical development, the period when children use more eyes in school, and the high-risk period of children’s myopia.
and
usually see less near and more far; Participate in more outdoor activities during the day; Balanced nutrition, eat less sweets and drinks, try to make children’s myopia happen later, the degree of myopia deepens slower, and the degree of myopia in the future is shallower, so as to avoid adverse consequences.
