The prevalence of myopia is very high in our society nowadays. From elementary school to university, students wearing glasses abound, and even kindergarten children are nearsighted. Genetically speaking, some myopia is hereditary. Some are not hereditary. Myopia is divided into pathological myopia, acquired myopia, and physiological myopia. Pathological myopia is mainly caused by genetic factors and is generally high in degree. Some studies have shown that autosomal recessive inheritance means that myopia may be passed on to the next generation if both parents have this condition, but it is not completely inherited and will definitely be passed on to the next generation. Acquired myopia and physiological myopia, which are caused by poor habits such as frequent Internet surfing, reading cell phones and other electronic screens and sitting and light problems, are not inherited genetically, but in a sense it has a “hereditary nature of bad habits”. For example, if a child is affected by bad habits in the family and becomes nearsighted, it can also be said to be a kind of “heredity”. In summary, pathological myopia is hereditary, but it is an autosomal recessive inheritance, so it is not necessarily completely hereditary, it is a matter of chance, acquired myopia is not hereditary, but we should pay attention to overcome “bad habits inheritance”.
