JAA don't permit such lenses and I can understand why to be honest. They'll get you through the tests, yes. Will they make you safer to fly an aeroplane? No. You're perfectly capable of doing that already; the science and statistics prove that. But hey, when did aviation ever let the facts get in the way of good old discriminatory legislation?
LOL
Well said Shunter.
I do recall reading of someone's account, who'd been overcome by the debilitating approach to mild CVD in their native country, so having dual nationality or something, moved to SA, and had no problem after some persistence. I guess the quoted text posted by Shunter would explain this then. I just don't know why some other parts of the world don't follow suit in light of the success of practical testing elsewhere...I just don't get it
