Besides, I don't know about the practical side of the medical in your country, but e.g. with Eurocontrol you have to see an ophthalmologist who has to fill out a - very thorough - questionnaire. Think he'll be keen on 'forgetting' to mention it? And what would it make you look like if they notice during the medical?
