Abstract: according to statistics, among the 1.3 billion population in China, the incidence of myopia is as high as 25%. Among them, teenagers are mostly myopic, and about 70-80% of students in middle schools are myopic. If it can be prevented, we must understand the causes of myopia and other influencing factors., “As the saying goes, ‘when you plant a melon, you get a melon, when you plant a bean, you get a bean’. This is the simplest interpretation of heredity.” Experts say the sclera of the eye has a signal indicating whether it should be long or short when the embryo is formed. This signal comes from heritable genes., Experts said that it is not difficult to find from clinical practice that both parents are highly myopic, and the probability of children born with myopia is greater than that of their parents, and only one of them is highly myopic; One of the parents has high myopia, and the probability of myopia of their children is higher than that of none of the parents. Therefore, from the perspective of eugenics, ophthalmologists do not recommend that both men and women with high myopia marry and have children., According to statistics, among the 1.3 billion people in China, the incidence of myopia is as high as 25%. Among them, teenagers are mostly myopic, and about 70-80% of students in middle schools are myopic. Whether it can be prevented, we must understand the causes of myopia and other influencing factors. It is generally believed that the causes of myopia can be attributed to genetic and environmental factors., Genetic factors play an important role in the occurrence and development of myopia. Some people have done a lot of family statistics, also known as family survey. For those whose parents have myopia, the percentage of their children with myopia is significantly higher than that of other families., In addition, Both parents are highly myopic (more than 600 degrees), almost all children are highly myopic. Myopia is related to ethnic groups. Ethnic groups with high myopia rate include Asian Americans, Singapore, Japan and China, which is related to genes. In Singapore, which is composed of Malay and Chinese Americans, under the same living environment, the myopia rate of Chinese Americans is much higher than that of Malay Americans. Chinese experts once found the prevalence of myopia in twins The results show that the consistency rate of myopia in twins is higher than that in non twins, which also shows that myopia is a genetic disease., The study also found that the parental families with high myopia have a high probability of high myopia in the next generation, but the genetic tendency is not obvious for the general low degree myopia.,
“as the saying goes, ‘you get what you sow, you get what you sow’, which is the simplest interpretation of genetics.” Experts say that when the sclera of the eye is formed, there is a signal indicating whether it should be long or short. This signal comes from heritable genes.
and
experts said that it is not difficult to find from clinical practice that both parents are highly myopic, and the probability of children born with myopia is greater than that of only one parent; One of the parents has high myopia, and the probability of myopia of their children is higher than that of none of the parents. Therefore, from the perspective of eugenics, ophthalmologists do not recommend that both men and women with high myopia marry and have children.
according to statistics, among the 1.3 billion population in China, the incidence of myopia is as high as 25%. Among them, teenagers are mostly myopic, and about 70-80% of students in middle schools are myopic. Whether it can be prevented, we must understand the causes of myopia and other influencing factors. It is generally believed that the causes of myopia can be attributed to genetic and environmental factors. Genetic factors play an important role in the occurrence and development of
and
myopia. Some people have done a lot of family statistics, also known as family survey. For those whose parents have myopia, the percentage of their children with myopia is significantly higher than that of other families.
in addition, Both parents are highly myopic (more than 600 degrees), and almost all children are highly myopic. Myopia is related to ethnic groups. Ethnic groups with high myopia rate include Asian Americans, Singapore, Japan and China, which is related to genes. In Singapore, which is composed of Malay and Chinese Americans, under the same living environment, the myopia rate of Chinese Americans is much higher than that of Malay Americans.
Chinese experts have investigated the prevalence of myopia in twins and thought that twins suffer from myopia at the same time or do not suffer from myopia at the same time, that is, the consistency rate. The results show that the consistency rate of myopia in twins is higher than that in non twins, which also shows that myopia is a genetic disease.
and
studies also found that parents with high myopia have a high probability of high myopia in the next generation, but the genetic tendency is not obvious for general low-grade myopia.
and
summarize the causes and influencing factors of myopia. We believe that heredity plays a considerable role in high myopia, but the vast majority of teenagers have simple myopia, and the acquired environmental factors have a greater impact. Understanding these influencing factors and eliminating these adverse factors from all links can prevent and treat myopia.
