Astigmatism and severe myopia. They're easily correctable, but without glasses I can't see more than about three inches from my nose. At normal viewing distances I simply cannot even see things other people can see, like letters, small animals or children &c.
Without glasses I'd be severely crippled. I've conducted a few experiments trying to move around in public without them, and it's beyond frightening.
