I tried to find a thread to discuss this, but left my necromantic kit bag at home this week. I recently pulled out the polarized lenses that came with a pair of customized Juliets some years back. On a whim,I turned them so the axes of polarization were perpendicular to each other and held them up to a light. The result was an amorphous pattern of near complete blackout. Repeating the process with a new pair, also BIP, resulted in blackout of the entire overlapping section. So, have they changed the process in the last eight years or so? I recall that molding the filter into the lens resulted in less complete polarizing (poly fills in some of the grooves), and that info came straight from Oakley, so I guess they found a way around that?
