The eyes with high myopia are fragile, and if they are hit, they may cause retinal detachment. In the environment with large changes in air pressure, exercise may cause elevated intraocular pressure and retinal detachment.
But you don't have to worry too much. Just pay more attention to exercise. Go to the hospital to have your eyes examined and see what the doctor suggests. After all, the eyes with high myopia are very fragile, so it is necessary to check them once every six months.
