Classic meets contemporary in CROSSHAIR® 2.0, the latest rendition of a lightweight C-5 alloy metal frame that merges classic aviator design with a contemporary lens shape and subtle sculptural details. The two lenses are cut from a single toric shield and mounted precisely to maintain the original contour. Oakley’s POLARIC ELLIPSOID™ technology ensures clarity at all angles of view, and optical precision meets ANSI Z80.3 standards. Jacketed with UNOBTAINIUM® to increase grip with sweat, the sleek stems are part of a comfortable Three-Point Fit that gets a dose of dimension with icons that integrate with the hinges. Numerous lens/frame color combinations are available for CROSSHAIR 2.0, and all lenses are crafted from pure PLUTONITE® to optimize impact resistance and filter out 100% of all UVA, UVB, UVC and harmful blue light up to 400nm. HIGH DEFINITION OPTICS&Reg; (HDO&Reg;) is a standard feature, and you can choose Oakley HDPolarized lenses that match unbeatable performance with greater than 99% glare-cutting efficiency. You can get CROSSHAIR 2.0 with corrective lenses (+2.00 through -3.00 combined power), and many options are available with Oakley Authentic Prescription Lenses.
