Laser etched with LIVESTRONG? near the edge of the lens, this unique rendition of the Straight Jacket is the rebirth of aggressive styling that first emerged more than a decade ago. The Iridium lens coating has always been a Lance favorite for the way it cuts glare and balances light in bright sun, and the comfortably lightweight O Matter frame proudly carries the colors of the Livestrong foundation logo. The Livestrong foundation inspires and empowers people affected by cancer, and Oakley is supporting its ongoing mission by providing $20 from each sale of this Livestrong special edition. This pair of sunglasses utilizes permanent Hydrophobic lens coating, a technology that maintains a smudge-resistant barrier against skin oils, sunscreens and lotions while repelling dust and preventing water from leaving sheens that can corrupt vision. In addition, the pure Plutonite lenses filter out 100% of all UVA, UVB, UVC and harmful blue light up to 400nm. This style meets every standard of ANSI Z87.1 for optical performance and impact protection. The peripheral clarity of XYZ Optics is just one of the patented innovations that make High Definition Optics (HDO) unbeatable. To optimize comfort and performance, Unobtainium components increase grip with perspiration while a Three-Point Fit holds the lenses in precise optical alignment.
