A National Institutes of Health (NIH) study has found that although 94 percent of Americans aged 12 and older have good vision, the remaining six percent, or 14 million, are visually impaired.
So 6% of Americans are visually impaired, and of those, 3/4 can be corrected with glasses.
that is a fairly blunt assessment. ‘Correction’ is not a binary after all.
After cateracts surgery I’ve got 20/80 vision in my better eye. Technically both eyes.
HOWEVER.
I have no useable depth perception. The retina on my left eye is swiss cheesed with holes and scarring from birth defects. My right retina has a major deflection in it and I ‘won’ the lottery in having it detatch post cateracts surgery (a nominally single digit percentage chance of happening) and thus needed further surgeries to correct.
was trying to figure out what the stats are on vision impairment, and found this:
