user11749: Answering this question, I was wondering how visually impaired or blind a player should be to participate at the IBCA Chess Olympiad for Blind and Visually Impaired Chess Players.

user224: Searching the web, I haven't found anything directly answering your question. However, the rules supplements for blind chess apply to games between a sighted player and one who is legally blind. Thus it seems a safe inference that one would need to be legally blind to participate in IBCA events.
