A few weeks ago I bought a pair of polarized Oakleys to wear when I fly.
At the time I bought them, I was unaware of the controversy surrounding
polarized lenses. If I had known, I may not have bought them. Honestly,
I have not noticed a single diffrence in the plane when wearing them.
Although, I haven't been actively looking for anything...


You really need to evaluate the difference of "with" and "without".
Just lift the glasses then return them to the normal position a few
times in different lighting conditions and while observing different
scenes. In particular, note the difference when looking at something
that reflects light, such as water or glass. With them on, tilt your
head to the left then right and note the difference.

The alignment of the polarizing grid makes quite a difference. I used
to have a pair of surplus polarizing filters for bimoculars that had
a mechanism for rotating the lenses. The reduction in glare was quite
dramatic when adjusted to the optimum position when looking over water.
Of course with normal sunglasses your only option is to tilt your head
one way or the other.
