BAJIO NATO BLACK MATTE SILVER MIRROR POLYA bold, squared, statement frame that employs oversized temples to block sidelight and keep the focus on whats in front of you. A large frame can be heavy, but not when its made of our lighter and stronger castor based bio polycarbonate. Bajo polarized lenses with proprietary LAPIS technology slice through glare for better fish spotting, while blue light blocking prevents eye fatigue to maintain visual acuity during marathon days in the sun.
