This theory is not my own it is how I understood it...personally I could n't be bothered either way in my environment. If I was to get into a combat situation here I would just wear my grey/m frame 3.0 and spend my preparation time getting as fit as possible and the rest on the shooting range.
I spend plenty of time training, which includes personal fitness, LOTS of time behind the sights of a weapon(s), among many other things. You may or may not be correct, but polarized lenses are just something I absolutely prefer and have never encountered any issues due to the polarization of any of my lenses.
