[unholiness]

Almost everyone who is legally blind is partially sighted. The two legally blind people I know both tell me those were most screwed over were the ones who learned to read braille in school instead of printed text. In this world, it's invaluable to simply be able to pull a sheet of paper up right up to a thick lens over your eye and slowly read it. If you only know Braille, you're helpless to solve this predicament, and Braille documents are extremely rare.

For digital media, screen readers are an enormous accessibility feature, but having (impaired) vision and knowledge of english is a helpful fallback for the plethora of poorly built sites and applications that have, say, text in an image. Braille is not helpful in a world of flat screens.
