I was browsing Eric Brook's site, which was recommended up above by claiborne:

Eric says that many people prefer that their kids learn shooting with iron sights first, then maybe learn with a scope. He makes a ghost ring sight that is a replacement for the rear sight on CZ 452s. He says it helps aging eyes that can't focus on both the rear & front sights (like me). My kid probably won't need the ghost ring though, his eyes are a lot better than mine.
