Also keep in mind what the AIM reads in section 8-1-6 Vision In Flight;

3. Excessive illumination, especially from light reflected off the
canopy, surfaces inside the aircraft, clouds, water, snow, and desert
terrain, can produce glare, with uncomfortable squinting, watering of
the eyes, and even temporary blindness. Sunglasses for protection from
glare should absorb at least 85 percent of visible light (15 percent
transmittance) and all colors equally (neutral transmittance), with
negligible image distortion from refractive and prismatic errors.

Specifically the part about "all colors equally". This refers to the
"Blueblocker" lenses or other similarly tinted lense. Also
"distortion...refractive...prismatic" I have heard these in arguments
against polarized lenses.

This is in the aim so it is not regulatory, but some like to enforce
anything that the FAA has published, I was asked not to wear my
polarized prescription sunglasses while flying, however I was not
cited.

SEE YA!!!
