Refractive errors can also be good and bad .

"Good" refractive error.

In childhood, many children will have some degree of farsightedness because the eyeball is still developing and the eye axis is relatively short. This kind of farsightedness is physiological, that is, normal.

As the child grows and the eyeball matures, this degree of hyperopia will naturally decrease until it disappears.

This physiological hyperopia can be understood as a kind of "reserve power" of the child's eyes, which helps to prevent the occurrence of myopia. Just like we save money, children have certain "farsightedness reserves" in their eyes when they are young, and these "reserves" are gradually depleted as they grow older to offset the risk of myopia.

Another "not bad" refractive error is mild myopia in adults, which in most cases does not affect vision.

Mild astigmatism is also "not bad", most people have it, and at temperatures below 75 degrees, it is sometimes negligible.

"Bad" refractive error.

By "bad" we mean refractive errors that are not easy to correct, or that may cause other serious visual problems. For example, high myopia (more than 600 degrees) can not only lead to vision loss, but also lead to serious eye complications.

For adolescents and children, if myopia develops too early and too fast, and cannot be controlled, it may develop into pathological myopia.

High hyperopia, anisometropia and large astigmatism, whether it is for ** or children, are visual "killers".

For children, it can lead to amblyopia – even with glasses, their vision will not reach a normal level, and they will not be detected and trained early, which will be detrimental to future life and career choices.

For **, high farsightedness, anisometropia and large astigmatism may not only leave lifelong visual impairment problems, but also require heavy glasses, and various visual fatigue problems will also come to the door.

I want to say,The word "refractive error" should be optimized in the doctor's pen- If the audience doesn't understand, if you can give them one less "hat", you can wear one less hat; After "wearing a hat", the author can sleep, and the family may not be able to sleep well for several days in a row.

Therefore, the child's physical examination book says "refractive error", parents should not be busy with brain buzzing, and distinguish their "good and bad".
