Sunglasses?

They are my favorites. I almost always wear polarized bifocals on
sunshiny days. They also work well in haze.

But... I only have one modern instrument, my Garmin 295 and I can see
the display in that quite well.

OTOH the radio in my car (Kenwood TMD700 144/440 MHz) has a blank
screen when I put them on.

I prefer them to any other type of glasses, BUT I'd want to try them
in any particular plane BEFORE flying.

I also wear photogray lenses in another pair, but found "Transitions"
(TM) to be useless.

I have worn polarized sunglasses for driving and flying for many years,
and prefer them to other types. The brown tinted variety seems best
to me. There is an occasional problem with an LCD screen, but since
I use flip-up type clip-ons, I just raise them as needed (as I do to
read sectionals of other printed matter). The worst problem with LCD
screens seems to be at the gas pumps of self-serve stations.

Drawbacks of clip-ons? They add to the weight perched on your nose.
They are also another set of lenses to collect dust (and keep clean).
They also scratch easily. OTOH they are pretty cheap.
