Authentically rooted in surf and skate culture, we went double-barrel with frame materials to create TwofaceTM, a rare look that pairs lightweight yet durable O Matter® with lower rims of aluminum. It sets you apart from the common crowd with clean lines that keep the look original, and with High Definition Optics® (HDO®), unbeatable clarity and proven protection go along for the ride. Oakley Twoface doubles up on comfort and style while bringing you visionary technology worthy of its metal icons. Pairing O Matter with aluminum was a radical notion but that's what it takes to sidestep trends and with sculptural earstems, delivers a lifestyle sunglass at the higher standard. The look is just plain smooth, and the optics are razor sharp. Oakley Plutonite® lens material makes it possible, along with innovations like XYZ Optics® to maintain clarity all the way to the lens periphery where conventional lenses distort vision. Plutonite filters out 100% of all UVA, UVB and UVC, and with impact resistance that meets ANSI Z80.3 standards, Twoface is ready for any life with impact.
