I'm personally delighted that contact lenses are now authorised
Can they really be allowed for air crew? Speaking as someone who wears contacts lenses, I know that they need to be changed regularly and that eyes become very tired and irritated when they remain in for more than a few hours.
I can't imagine a pilot needing to find the time to put eye drops in while flying a mission, or having to escape-and-evade for any prolonged period of time if they're ever unfortunate enough to have to eject over enemy territory while wearing their lenses.
