Should aeroplane pilots wear polarized sunglasses when they’re flying?
No. Pilots should avoid polarized sunglasses. Polarized sunglasses work by filtering out glare – concentrated light that is travelling horizontally. The instrument panel may also have a polarizing filter to combat glare. When the indicators on the panel are seen through polarized sunglasses, the combination of two polarizing filters can cancel most of the light entering the eye so you can’t see the instrument panel clearly.
