Hello, above 600 degrees belongs to high myopia, and it is not recommended that you do particularly strenuous sports, such as basketball running, high jump and spinning. You can do yoga, jogging and other soothing fitness exercises. Generally speaking, high myopia will lengthen the axial length of the eyes, which is like a balloon being blown up, the balloon wall will become thinner, and our retina will also become thinner, so the pressure it can bear will become smaller. If the patient takes part in strenuous exercise, such as running, playing basketball, long jump, etc. And there is a collision, it is easy to have retinal detachment, and the direct consequence of retinal detachment is blindness. So in addition to not taking part in strenuous exercise, I suggest you also pay attention to using your eyes to avoid collision.
