When myopia occurs in the eye, if the degree of myopia exceeds 600 degrees, it may cause deformation of the eye, mainly due to the process of myopia occurrence and development. As myopia deepens, the length of the eye axis gradually increases, which means that the entire length of the eye increases, and in this process, eye deformation, such as protrusion of the eyeball or posterior scleral staphyloma, may occur, mainly due to the increase of myopia. The higher the degree of myopia, the more obvious this symptom becomes, and this process is irreversible, once it occurs, it is impossible to return to normal again. So to avoid this, it is very important to pay attention to reasonable eye habits in general and try to slow down the development of myopia, especially in the adolescent and child stages.
