Sunglasses

I wear Polar Eyes ($50 from Aircraft Spruce or polareyes.com,
including a hard case and cleaning cloth). I love
them! They are very lightweight and comfortable.
I find the polarized lenses actually accent the contrast
of another plane against the sky. I prefer the copper
colored lenses. They have just a touch of blueblocking,
but won't make daisies look black. I have seen a couple
of canopies that produced some very mild color banding,
but most don't. Also, the rotation of thermals tends
to create a 'polarized' effect when they pick up dust,
pollen, grass, etc. You can see thermals for miles
with Polar Eyes. You can also see details in clouds
that aren't visible with non-polarized lenses, and
they cut through haze very well.

As for the post about the FAA 'asking' someone not
to wear polarized lenses, I'd 'ask' them take a hike!
