Exactly Rick. Here is a quote from the FAA's pilot safety brochure on sunglasses:
POLARIZATION. Polarized lenses are not recommended
for use in the aviation environment. While useful for
reflected light from horizontal surfaces such as
snow, polarization can reduce or eliminate the
instruments that incorporate anti-glare filters. Polarized
may also interfere with visibility through an aircraft
by enhancing striations in laminated materials and
sparkle of light that reflects off shiny surfaces such
aircraft’s wing or windscreen, which can reduce the
has to react in a “see-and-avoid” traffic situation.
