Second, genetic factors. According to a large number of investigation data, a relatively consistent conclusion is that high myopia is related to heredity, while there are great differences between moderate myopia and low myopia. The genetic type of high myopia is autosomal recessive. Therefore, the parents and children may not have myopia at the same time. Heredity is often affected by the objective environment, that is, the living conditions, which makes it variable and increases the complexity of heredity.

Third, environmental factors. Environmental factors are mainly close work and poor working environment, which is the oldest theory. Although there are still some controversies, from a large number of domestic and foreign research reports, it has been recognized that heredity and environment are the main causes of myopia, and pointed out that environmental conditions are the objective factors that determine the formation of myopia.
