If you already wear glasses, I like the nerdie flip up pola sunglasses
sold at Meijer (Michigan discount store chain) for 12 bucks. You can
quickly flip them up under a dark cloud, or when you want a non
polarized look at something. They may reduce glare at some angles but
half of angles are not effected at all by pola sunglasses. To prove
this look at a blue sky 90 degrees to the sun and the sky gets much
darker. But if you look at the sky directly toward the direction of
the sun or directly away from the sun, the pola has no effect. This
holds true with objects that glare and reflect as well. Only some
angles are polarized. As a result, sometimes white gliders really pop
out of a deep blue sky, there will be other times when glare reduction
might make it little harder to see. But glare reduction is less
effected by white. Dark colored gliders would be bad.

I really think one can not say for sure that pola sunglasses are worse
for seeing other gliders overall. I've just spent 35 years as an
automotive photographer. I used pola filters about 90 percent of the
time. They make it easy on your eyes and cut reflections inside the
canopy so you can see out better. So as long as you can read your
displays. Mine all work OK. ..Aaron
