Can you be blind?

Under normal circumstances, if it is physiological myopia, the degree rarely exceeds 600 degrees, so it will lead to a decline in distance vision, but after wearing glasses or corneal contact lenses, these methods can improve vision to normal and will not lead to blindness. However, if it is pathological myopia, this situation is caused by congenital genetic factors, so the degree of myopia may develop very fast, and the degree may be very high, such as more than 1000 degrees, or even more than 2000 degrees. In addition to causing far vision loss, there may be a variety of fundus complications, such as macular hemorrhage, macular split, posterior scleral staphyloma, retinal hole, retinal detachment, etc. once these serious complications are shown, it may lead to severe vision loss and even blindness.
