Cut from a recent thread on a similar topic. I would not let polarized drive the train for eyepro. If the eyepro in question is not on the list referenced below, I would be suspect. It seems like most of the referenced sets have a clear and grey lenses that are not polarized. FWIW.
...I have since learned that the the M Series of old does not meet the latest spec. I then consulted the previously referenced armed forces approved list: \

... and have been sporting ESS stuff ever since. I simply would not wear eyopro while shooting that was not on that list or made to that spec as per an eye professional I trusted.
YMMV Greatly."
