Scalpel Sunglasses - We make optical gear for those who play to win. Even if you re competing in casual sports, there should be nothing casual about performance. So if you re looking for a slice of style that s a cut above the rest, get something carved on the cutting edge of technology. Oakley Scalpel combines the best of High Definition Optics (HDO ) with a look that goes from street to sport, and it offers a level of performance as aggressive as its styling. This is sculpture mixed with science, and there s a reason behind every curve. The side-to-side contour of a lens can make or break peripheral vision. SCALPEL has a full 8.75 base curvature to open your range of view. That much of a contour leads to optical distortion in ordinary sunglasses but Scalpel is engineered with XYZ Optics to maintain critical clarity along the entire lens curve. You ll have added protection against sun, wind and side impact. As a matter of fact, this design meets ANSI Z87.1 basic impact standards, and the pure Plutonite lenses filter out 100% of all UV. The optics also meet every ANSI Z87.1 standard for visual performance. So if you hit the links or just crash a beach volleyball game, Scalpel will give you all the razor-sharp clarity you need. The smooth sculptural contours are made of durable, lightweight O Matter frame material, and we gave the stem sleeves special attention. Note how they wrap the ends and continue along the underside. They re made of Unobtainium , a material that increases grip with sweat, and they re part of a Three-Point Fit that maintains comfort all day while holding the lenses in precise optical alignment. The only thing left to think about is what options you want. Oakley HDPolarized lenses block the blinding rays of glare that are magnified by flat surfaces. Our polarization technology eliminates the haze and optical distortion that plagues ordinary polarized lenses. You can also get Scalpel with Iridium lens coating that further reduces glare while precisely balancing light transmission. And if you weren t born with perfect eyes, you can get Oakley Authentic Prescription Lenses.
