The vast majority of myopia is not a disease, but a decline in hyperopia function and compensatory changes in myopia function caused by bad eye shape. The root cause is too much myopia. Therefore, the prevention and treatment of myopia does not require medical methods, such as mydriasis and acupuncture and laser surgery to change the cornea (both of which have certain toxic and side effects). Taking mydriasis and acupuncture as examples, these two methods are effective in relieving pseudomyopia, but they are not thorough, especially for many years. People can't do mydriasis and acupuncture after reading and writing too much every week, which will make the nervous system disorder, make the vision repeat for a long time, and may also accelerate the development of true myopia. There are many such examples. Prevention and treatment of myopia should be based on its causes, that is, reducing myopia and practicing hyperopia. The best way to prevent and treat myopia is to exercise your eyes naturally. Physical exercise can make modern people's weak bodies healthy, and eye exercises can prevent myopia.
