Brian is Blind?

I'm looking for an old fic where Brian is blind. He lives with his mum, and had been blind for several years. He meets Justin, but I can't remember what the circumstances around it are. They become involved and eventually want to move in together, which makes Joan worried.
Anyone?

ETA: thanks to [livejournal.com profile] known_anonymity it's Eye of the Beholder by Rena. Link inside :))
