Quizplus · Accepted Answer

The gray green color has always been a popular choice for sunglasses for pilots.
When looking through a gray green color, it does not distort other colors, and in hazy conditions the grey green combination enhances contrast. It is not recommended by the FAA for pilots to wear polarized lenses as they may interfere with seeing through the windshield and the pilot may not be able to see the instrument panel.
