Im giving a vote for Bolle.
A sandstone (yellow ish orange ish) non polarised lens.
Unfortunately the model I wear has been discontinued. So has the lens type, I guess they werent that popular. I LOVE EM. Im on my second pair of the snake eyes style now, but had three pairs in a now discontinued aviator style frame with the same sandstone lens. I was in a sunnglasses shop recently and asked about the cost now, of the same glasses, she told me it was discontinued. By luck another shop in the same mall had one pair, exactly the same, I snapped em up to store away. I usually get 2-3 yrs plus from my sunnies, but here in sunny northern NSW, Australia, I wear them just about every day of the year.
