I have a all glass panel in my RV-8 and I'm wondering what are the best sun glasses. I find that it is a little hard to see with "regular" glasses.
Most anything non-polarized will do.

Not all polarized lenses behave the same way.
Thank you, thank you, thank you, Roger. I have been mostly flying with no sunglasses since last October, when I lost my non-polarized clip-ons at LOE. I did a lot of internet searching, posted to this website and consulted with local opticians and could find no source for non-polarized clip-ons. I figured it would only take me a few seconds to check the Hazebuster website but didn't expect to find what I needed, but Voila, there it is. My order is in!...I haven't seen Hazebuster mentioned, so have to put in a plug...
I am only repeating something I was told long ago and I've believed it every since, but can't offer proof. This forum may provide more information on it.
Polarization has the effect of stopping some light - light that is itself polarized for whatever reason. The problem, I was told, is that it fools your iris into staying further open. Of course, if your lens also blocks 100% of all harmful rays, both types of UV included, then perhaps it won't matter.
Any experts willing to clear this up?
Yes, the most damaging lenses for your eyes are either gray or polarized (or both) which don't block all UV light.
Beware cheap sunglasses.
Hmm. I bought a pair of non-polarized neutral gray Randolphs some time ago, partly on the basis of being standard issue to various military forces... Now wondering if I should consider a change... Has anyone made the comparison between the brands/tints mentioned in this thread, and my "reference" lenses?
You want non-polarized for two reasons: one, you want to see the reflected glare off the wing of traffic. . .
Ah, the debate will rage endlessly.
I for one LOVE the polarized glasses. Yes, at certain head tilt angles I can "blank out" my EFIS or a small section of the plexi - but it is OBVIOUS. Solution? Tilt your head back where it was. If the BAD angle is "head straight and level," try different glasses.
The advantage of polarized comes when flying in any sort of haze, which is nearly 100% of the time in Georgia. I will pick up traffic 50% further away with the polarized lenses, and in reduced visibility I can usually get similar distance gains watching for towers & terrain.
Amber tint is almost mandatory - gives the very best contrast against almost all sky conditions. Gray tint on a gray day will simply reduce your sight distance - baad!
It's like any other system on your airplane - you need to know the capabilities and limitations and, thus armed, make your personal decision.
