The Oakley Four™ sunglass takes design cues from retro-inspired styling. Four-base lens curvature reduces side rake to position the lenses in a defined plane in front of the eyes. Frame geometry compresses vertical dimensions for a lateral spread with distinctive angles. Augmented with true metal icons, the O Matter™ frame features a sculptural hinge design. The Oakley Four™ achieves optimum clarity with the use of pure Plutonite™ lens material, a proprietary innovation that blocks 100% of all UVA, UVB, UVC and harmful blue light.
