"I have a pair of polorized Bollé and I noticed that they will make the LCD
screen on the stereo in my car and truck appear black when looking through them. I don't believe they would be good for flying as they might also have the same effect when looking at instuments. -Dan"
Polarized sunglasses are definitely out for flying. They make it difficult to see your instruments and change your visual acuity. ASk any pilot or IP and they will tell you that is the case.
The average pilot I know wears whatever is comfortable, and I do tend to see Ray Bans (aviators) more often than not. That said my friend Bob the Scottish Georgian loves his really ugly womens sunglasses that I'm sure he stole from his wife....since they were already paid for. Cheap bastard!
