I'm getting new sun glasses, should I get Polarized or not, what works best for flying gliders???



The ones I'm looking at are also anti-glare lenses.

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.

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.

Polarized glasses may, or may not blacken an LCD display: it depends on the technology, the angle of the polarizing filter, etc. It is easy enough to try with the electronics you have, to discover if there will be a problem. I prefer polarized glasses as well, could not wear them with an iPaq PDA in the cockpit, but with an Avier/V2/Oudie they are fine.
