Go the whole hog and get Serrengetis made to your prescription. We get Serrnegetis on company issue (non-polarised because jet windscreens are polarised and the helicopters are full glass cockpits which you can't see with polarised lenses) I keep a pair in my briefcase, a pair in the car and a pair in my own aeroplane because they give superb cloud definition when I'm vfr in my little toy. They make other traffic really easy to see and are unbelievably comfortable.
For looking like a cool diver dude when I'm on holiday its Oakley.
