The 04214 A4X Y2 Gunmetal Grey Blue Polarized are Polaroid's exact copy of the classic pilot style with the teardrop shaped lenses, thin metal frame and arms and double bridge. Here of course the difference is firstly the price compared to a pilot, but also the lens which as standard is polarized as all are. The glare reduction is exceptional, colour perception therefore is correct with a clarity of view that is hard to beat.
