High myopia is not recommended to do skydiving because skydiving is an extreme sport, in the whole process of movement, due to changes in air pressure, there is a possibility of intraocular pressure, there is a possibility of forming complications of retinal detachment. This is mainly because high myopia, with the deepening of myopia, the eye axis is gradually stretched, so the retina gradually becomes less solid in the process of stretching, and strenuous exercise may cause the retina to detach from the surface of the eye. This disease can have a serious impact on visual function, and the longer and more extensive the detachment, the greater the impact will be. Once this disease appears, you need to go to the hospital for an early fundus examination, and if diagnosed, you need to reset it with surgery early to avoid irreversible effects. Therefore, high myopia must be careful to avoid strenuous sports.
