Prior to my cataract surgery, my vision was 20-400. According to "some," particularly one optometrist that I spoke with, I was "legally" blind. I could not make out faces at a distance beyond, say 30 yards or so, but I could certainly see the individuals and could have been capable or aiming a firearm at them and hitting them. Without knowing the actual extent of the "blind guy's" visual capabilities, I'd hate to judge that he was blind. Now, if he was wearing the shades and carrying the white cane, that could be another issue.
