Offering you the best of both worlds, the Oakley Polarized Double Edge Prizm Sunglasses provide an unobstructed field of vision and protection from the sun's UV rays without overwhelming your face. The Double Edge features a shield-inspired silhouette, maintaining that sporty look you've come to know and love from Oakley. Perhaps more importantly, though, the Double Edge is equipped with durable Plutonite lenses that are outfitted with Oakley's Prizm technology and polarized treatment. The two technologies promote an interconnected experience--Prizm tech enhances color contrast, reduces glare, and provides a premium optical experience, while the polarized treatment keeps those nasty UVA, UVB, UVC, and harmful blue lights at bay.
