I miscalculated my health benefits. I expected to have to pay cash for
my medical and for some diagnostic tests that I needed to have to get
the medical, but my HMO ended up picking up all of it. So I have a
signficant surplus in my healthcare flexible spending account that I
must spend by the end of the year or forfeit to the IRS.

I will probably spend it on prescription sunglasses. What are the best
sunglasses for flying if money is no object (I REALLY miscalculated)? I
already have a pair of prescription ray-bans which are pretty good but
not so great in hazy, glary conditions.

I'd like to hear any opinions on this, like are mirrored shades better
at reflecting bright light? ARe wraparounds really better at protecting
your eyes from all angles? Etc.
