RE: What sunglasses are you using?
polorized glasses are fine, just make sure it doesn't block the readout on the radio. Personally I have perscription arnette sunglasses non polorized. Non polorized becuase in the real plane the polorization revealed the individual layers in the plexi glass of the windscreen, just not a good situation when flying, and also couldn't see the screen on my futaba radio.
