Polaroid lenses.
G'day Chaps, I wanting to get some new sunnies that'll fit under my headset a little better. Can anyone tell me if polaroid lenses really cause any dramas at all, in regards to viewing instruments etc? Cheers.

The Polaroid debate
Haven't we been through this already recently?

Plenty of arguments here - for and against.
Use whatever you want. If you're worried about the eyewear police that much, carry a pair of each.

There's not much to debate. Polaroid lenses DO cause problems, in particular with depth perception as previously posted.
I again remembered to be careful just this last Sunday. I was putting an aircraft away back into the hangar. It's a tight fit and I found myself hitting the wing on the door twice within 30 seconds which I don't normally do. It's hard at the best of times to judge the position of the door over the wing, but seems much harder with my Oakley Polaroid's to the point where I have to take them off to finish the job.
I'm not sure exactly how this would affect someone's ability to fly / land an aircraft, however it's worth thinking about.

I think King Air windows (PAX) work off polaroid... two films, and the inner one can be spun around so it blocks out the light.
If you have 2 sheets of polaroid, if they are rotated to the right angle, there's no effect, but keep spinning them and it blocks out nearly all light (and visibilty) through it.
Personally I'd stay away from polarised if I was buying aviation specific glasses, because of the chance it could block out my GPS, or later a EHSI or similar
Get a nice pair of Ray Bans or Serengetis instead
Arrr!

Are polaroid lenses those sunglasses you shake for a few seconds until they dry, then a picture appears?
......yeah, but the picture is usually of some fat, hairy '70's broad. No one needs to see that.

Have a try out of a set of glasses with neutral density lenses of whatever density you fancy ... much better for flying ... and keep the polaroids for fishing and sailing ...
