With each sale of this special edition sunglass $20 will be provided to the foundation. This is your opportunity to help support a noble cause & wear a symbol of inspiration & empowerment. Oakley SCALPEL™ is a rare breed that goes from sport to street with style to spare & we rendered this special edition with the colors of the LIVESTRONG Foundation. These sunglasses come with all the performance & clarity you need along with superior impact protection & dawn-to-dusk comfort. We laser engraved &8220;LIVESTRONG” on one of the Black IRIDIUM lenses & the lens tint will help you maintain color recognition on bright sunny days. Choose Scalpel for a slice of style that&8217;s a cut above the best & choose this edition to show your support for a noble cause. Oakley SCALPEL™ combines the best of HIGH DEFINITION OPTICS (HDO) with a look that goes from street to sport & it offers a level of performance as aggressive as its styling. This is sculpture mixed with science & there&8217;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&8217;ll have added protection against sun wind & side impact. As a matter of fact this design meets all ANSI Z87.1 basic impact standards & 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 from durable lightweight O MATTER frame material & we gave the stem sleeves special attention. Note how they wrap the ends & continue along the underside. They&8217;re made from UNOBTAINIUM a material that increases grip with sweat & they&8217;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 & 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. & if you weren&8217;t born with perfect eyes you can get Oakley authentic Prescription Lenses (+2.00 to -4.00 combined power).FRAME: &9632; Durability & all-day comfort of lightweight stress-resistant O MATTER frame material &9632; Comfortably secure fit of UNOBTAINIUM nose pads & stem sleeves that increase grip with perspiration &9632; Performance & comfort of Oakley Three-Point Fit that holds lenses in precise optical alignment &9632; Metal icon accents LENS: &9632; Optimized peripheral vision & side protection with 8.75 base lens curvature &9632; Optical clarity performance & precision that meets ANSI Z87.1 standards &9632; Protection of impact resistance that meets ANSI Z87.1 basic impact standards &9632;UV protection of PLUTONITE lenses that filter out 100% of all UVA UVB UVC & harmful blue light up to 400 nm &9632; Glare reduction & balanced light transmission of IRIDIUM lens coating
