response: I do not. Do you know anyone blind ? Those have total or lose to total vision loss
original_response: Not closely but it's a very sad situation when someone has complete vision loss. Even when not fully. Today I actually saw someone blind, they had a dog, helping them.
history: Do you know anyone with visual impairment? I feel so bad for anyone I know who does
knowledge: The term blindness is used for complete or nearly complete vision loss.
