Myopia does not lead to smaller eyes. Many people feel that their eyes have become smaller because of myopia, which leads to blurred vision, so many people like to squint to see things, which gives the illusion of smaller eyes. As myopia deepens, if the degree of myopia exceeds 600 degrees or more, it will lead to a change in the shape of the eye, which will appear as a protruding eyeball or posterior scleral chylomalacia. There is no effective treatment for this performance, and the process is an irreversible one. Therefore, in order to avoid this situation, once the eyes show myopia, you should wear glasses early, maintain reasonable eye habits in general, control the speed of myopia development, and only control the degree of myopia to the lowest possible state to avoid serious effects on vision.
