I think I can help you answer that one Speedbird 12T! The RAF requiers perfect un-corrected eye sight. Howeverm the airlines usually allow it aslong as your glasses do correct your vision to make it perfect. For example, if you were just short-sighted and your glasses corrected that, that would be ok. But, if you were for example colour blind, no magic pair of glasses will correct that, and so the answer is no! :p
