How many “black pots” did glasses carry in those years?

Abstract: wearing glasses can lead to eye deformation! With the development of myopia, the anterior posterior diameter of the eyeball will also become longer. Generally speaking, when the average degree increases by 300 degrees, the corresponding eye axis length will increase by 1mm.

about these “black pots” it’s time to redress. Many parents are especially reluctant to match their children’s glasses when they first find that their children are short-sighted. They think they can’t take them off as long as they wear glasses, and they will wear them longer and longer! In fact, whether the child’s myopia deepens has little to do with the glasses themselves. As long as the factors leading to myopia are still there, such as lack of outdoor activities and excessive burden of using eyes every day, the degree of myopia will continue to deepen, which has little to do with wearing glasses.

glasses should be lower! General myopia glasses are prescribed to glasses with the minimum degree that can see the best vision. Assuming that wearing 300 degrees can see 1.0, wearing 275 degrees can see 1.0, and wearing 250 degrees can only see 0.8, it should be matched according to 275 degrees. If the degree matching is less, you can’t see the most clearly in the most relaxed state of the eyes, which will make the eyes easily tired and the imaging on the retina is not clear enough. Therefore, if the degree is lower, it will make the development of myopia faster. Similarly, the degree can not be matched with depth. With depth, the eyes will need more adjustment when looking close, which will also accelerate the development of myopia. Therefore, the suitable is the best.

wearing glasses will cause eye deformation! With the development of myopia, the anterior posterior diameter of the eyeball will also become longer. Generally speaking, when the average degree increases by 300 degrees, the corresponding eye axis length will increase by 1mm. Therefore, people with high myopia, especially those with more than 1000 degrees, will have a much longer eye axis than ordinary people, which may be manifested as exophthalmos.

and

glasses do not need to be worn all the time. At present, the mainstream view holds that glasses need to be worn all the time, so as to obtain better visual quality. Only when the degree of myopia is very small (< 200 degrees) and the near vision clarity is not affected, you can consider wearing glasses when looking far and not when looking near. If the degree of myopia is deep, or astigmatism is combined, you need to wear glasses all the time.

after knowing the truth, do you think glasses are more unjust than Dou E!
