Also, on a more general note:

Some canopy materials have bad interactions with polarized lenses.
When I was training in a Diamond DA-20 I made the mistake of wearing
polarized lenses once and was treated to a wonderful changing moire
pattern all over the canopy, as I turned my head - ugh!

So check your canopy as well as your PDA, before you drop a lot of
dough on fancy lenses!

And last but not least, with polarized lenses reflections are suppressed.
That means that you easely miss a sun reflection in the cannopy of an other
glider.
Missing other traffic means an increased risk of collission.
No polarized glasses for me in the cokpit!!



It is possible that you might miss a sun reflection on a glider.
However, polarized gliders make the sky much darker, so in general they
make other gliders stand out. They also help with the visibility of
distant clouds.
