As a couple of others have pointed out there are BIG issues with polarised lenses in aircraft with window heating. You'll get a lovely but very significant rainbow effect when looking out the windows. It's hugely distracting and makes it impossible to operate effectively. It's also getting very hard to find glasses (particularly prescription glasses or clip ons) that aren't polarised so make sure you sus it out. Most guys I fly with recommend the serengetis.
Don't underestimate the issue of wearing sunnies with a head set. Even a light weight head set such as we use in QF can cause big head aches when worn in concert with sunnies (or normal glasses) that have thick arms on them.
