I can't imagine being born with a visual impairment, can you?
I would hate to have to wear glasses.
I actually wear glasses, and it's no fun. What other types of visual impairments are there?
It is anyone that was 20/40 or 20/60 vision.
Oh wow! I think mine is way worse than that so I guess I qualify! Is being color blind a visual impairment?
Yes, if you don't have the ability to see color.
That's interesting. I wonder what causes visual impairments? 
I think some visual impairment has to do with cataracts.
