SUN GLASSES

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.

Thanks

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.

Assuming that you fly with your head held perpendicular to the wings
(rather than the ground and cloudscape) then polarised glasses will give
you a different picture when circling to flying straight. Try it on the
ground - look through a polarised lens at the clouds then rotate 60
degrees.

IMO you are best off with a good anti uv tint like Zeiss Sky which is quite
yellow.

DO NOT FLY WITH NON POLORIZED LENS!
by doing so you trick your eye into opening wider because of the
shade. Remember polorization is used to protect from UV light. If
you open your eye wider by non polarized glass you expose your
eye to that UV light. You will damage your eye much quicker. It is
not a function of can you see your instruments or not. Do not be
mislead into this kind of thinking......
Most glider canopies are not made with polorized protection.

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.

Never mind, I searched and see there are lots of post about this subject.

If you are old enough to need readers to see the instruments (like I am), finding good quality polarized glasses with built in readers can be challenging. Maui Jim makes a few versions and they are very high quality, but very expensive too. I settled on SunCloud that has a few models with standard power readers for $60-$80 new on Amazon.
