Abstract: People’s eyeballs will not mature until they are about 20 years old, while teenagers’ eyeballs are in the growth and development stage, so they have a great chance of myopia or deepening myopia., For many people with myopia, there is always such a concept in their mind: with the growth of age and the reduction of long-term eye use time, their eyesight will tend to be stable, and the degree of glasses will no longer increase. But in fact, many people will find that their eyesight is getting worse and worse when checking their eyesight. Some people even worry that the degree of myopia can not be controlled. So why did this happen?, There are two reasons for the deepening of myopia. One is pathological myopia, which is a lesion inside the eye and is hereditary. It shows that myopia continues to deepen and increases rapidly. If the degree of myopia increases by more than 100 degrees or even more than 200 degrees within a year, or the accumulated high myopia reaches 2000 degrees, it is likely to be pathological myopia. At present, posterior scleral reinforcement is widely used in the treatment of pathological myopia., Another reason is that you don’t pay attention to eye hygiene and incorrect eye habits. For example, if the lighting is too bright or too dark, you use your eyes for too long, and you don’t diagnose and treat eye diseases such as trichiasis, ptosis and keratitis in time, you will aggravate myopia. This reason is more common. In addition, there are some claims in the medical community that myopia is related to the lack of trace elements such as calcium and chromium, or excessive carbohydrate intake in childhood, but these have not been finally verified., People’s eyeballs don’t mature until they are about 20 years old, while teenagers’ eyeballs are in the period of growth and development, so they have a great chance of myopia or deepening myopia. Relatively speaking, the visual acuity of adults should be relatively stable, but it is also common for adults to see computers and read for too long, and their eyes are tired for a long time., Eight good habits can prevent myopia.

people will not mature until they are about 20 years old, while the eyeballs of teenagers are in the period of growth and development, so they have a great chance of myopia or deepening myopia.
