The ones I'm looking at are also anti-glare lenses. Thanks Glen If you use _ANY_ electronics in the cockpit at all (even a digital- display variometer), you do _NOT_ want polarized lenses. The lenses will appear to "black-out" those displays at some (or all) viewing angles. Also, some canopy materials will cause them to look like a checkerboard when viewed through polarized lenses. I won't bore you with the science/physics, but in general you're best off with non- polarized lenses for aviation use. --Noel This is incorrect. I am using tons of electronics in the cockpit with polarized with no problems. the only device I ever had a problem was with the rectangular butterfly display in landscape mode, but resolved it. I wouldnt fly with regular sunglasses as I find the polarized superior due to reducing canopy glare and increasing detection of clouds and traffic. Ramy

This agrees exactly with my experience. I have been using brown tinted polarized glasses for more than 30 years with good results. The Butterfly display is the only one that there was a problem with. problem solved by scrapping the display.
