When I mean eye correcting surgery, I’m talking about things like laser eye surgery that fix your vision. I mean, I think laser eye surgery works by slicing tiny pieces of the cornea in order to change the shape of the lens into a shape that correctly reflects the light. But how would the surgeon know how much to cut off? Also, if your eyes can degrade to the point at which you become legally blind, then how come legally blind people don’t get vision correcting surgery?
