I ordered a pair of Ray Ban sunglasses with prescription lenses for use while flying. The lenses I got originally had no polarization but there was a colour distortion (brown / red hue despite being a grey lens) so I brought them back. They sent them to the lab and they said that was because of the anti scratch / UV coatings etc. which are made for use with polarization.
They said there is a special polarization where it's only done on the backside of the lens which makes it compatible for use by pilots as it doesn't distort LCD screens etc. Does anyone know anything about this? Would that be suitable for flying or should I be concerned about not seeing reflections from other traffic in the air etc.?
Any input is much appreciated, thanks!
