Don't let the relaxed look of the Oakley Sliver Polarized Sunglasses fool you. Their laid back style has tech heavy reinforcements that only Oakley could serve up. The HDPolarized Plutonite lenses with Iridium coating allow you to eye up the incoming swell without any glare, haze, or optical distortion that sometimes is found in lesser polarized sunglasses. Not only are you protected from any damaging UV rays, but you're also safe if an errant volleyball strikes your face while mindlessly gazing at the surf. Your face will sting a bit and your ego might suffer, but your glasses will be just fine thanks to their ultra lightweight, resilient NanOmatter frame that has highly durable flexibility under serious impact. Built for all day comfort on the beach, Oakley outfitted the Sliver's with Three Point fit, cutting down on all of the painful pressure points through minimal contact, while securing a snug fit for ideal optical alignment.
