I've had face blindness since late 2004. When I'm at the local Signing Community events in Cincinnati, OH, USA and there is a large turnout, I can't make out the faces of people from more than 6 feet away and I don't know if anyone I know is there. It really sucks! I consider myself visually impaired nowadays. My visual acuity was 20/20 in both eyes but now it has reduced to 20/30.
