The chance of going blind with 1000 degrees of myopia is judged by the presence or absence of complications and cannot be generalized. Although 1000 degrees of myopia is a high degree of myopia, as long as there are no complications, the chances of blindness are not high and can be corrected by wearing eyes or having laser surgery. If there are complications, the chances of blindness are high. Patients with glaucoma often have symptoms such as soreness at the root of the nose, eye swelling and pain, dizziness and headache, and rainbow-like halos around the sight of incandescent light. Patients with cataract often have symptoms such as fixed dark shadows in front of their eyes, dark shadows on which side they look, fear of light, and seeing objects in dark colors. These are all complications and need to be treated. High myopia requires regular eye examinations to prevent the development of lesions in the fundus of the eye from being effectively treated, which can have serious consequences. At the same time, avoid strenuous activities in life, reduce long time looking at cell phones, work and other close eye activities.
