Could it be because if the tempered windscreens? You'll see the [don't know what the name is in Englisg] 'spots' with polarized.

I see the spots in glass when I wear polarized glasses but never through my own front windshield. In teh rear and sides and on other vehicles. Buildings and homes even.

That's what I mean. Aren't airplane windshields tempered as well?

Just for your information I ended up getting Polished Chrome/black iridium setup for my Crosshairs. Did a BTO.

i think this explaination i got would help better...

Polarization and Aviation

"Blind spots" or distortions when looking through a laminated glass or polycarbonate windshield while wearing polarized sunglasses can be a problem.

Polarization and flying don't mix as your aircraft canopy flexes in-flight and creates polarized fields within itself that appear, move, and dissappear constantly. The problem? Polarised glasses behind a temporaraly polarised canopy means you could be flying blind at times and never know it. It's not worth the risk of missing another aircraft in your scan and then getting a big surprise shortly there after. Also, many instruments have polarised filters on their displays, With polarised glasses, you might not be able to read your GPS even when you are two feet away.

excellent then. now i have no regrets for not getting the polarized lenses.

Post some pics of those Xhairs- Chrome/Black sounds cool.

will do once i get a chance.
