In US: about 1% of the population is blind; about 1.3m Americans are "legally blind" - which is defined as " visual acuity with best correction in the better eye worse than or equal to 20/200 or a visual field extent of less than 20 degrees in diameter"
Really? This day and age? No one in my life is blind, so I just assumed at least some minimally level of accessibility.
I wonder how many blind and sight-impaired people there are in the general population?
