Abstract: Generally speaking, children’s growth of 50-75 degrees in one or two years and adults’ growth of 50-75 degrees in two or three years belong to the normal category, and there are usually two reasons for the deepening degree of 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?
myopia deepens for two reasons.
generally speaking, children’s growth of 50-75 degrees in one or two years and adults’ growth of 50-75 degrees in two or three years are normal, and there are usually two reasons for the deepening of myopia.
are pathological myopia.
are lesions within the eyes, which are hereditary. 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. Posterior scleral reinforcement is widely used in the treatment of pathological myopia. Another reason for
is that they do not pay attention to eye hygiene and have incorrect eye habits.
for example, if the lighting is too bright or too dark, the eye is used too long, and eye diseases such as trichiasis, ptosis and keratitis are not diagnosed and treated in time, myopia will be aggravated. 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. The eyeballs of
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. Relatively speaking, the visual acuity of adults should be relatively stable, but it is also very common to see the computer and read for too long, and the eyes are tired for a long time.
