It took three decades to achieve next to nothing. That's the only way to describe the weight of the Oakley MPH Nanowire 1.0 Sunglasses, a titanium alloy frame that practically feels buoyant in air. But the real breakthrough is the adaptable fit, a benefit of memory metal that allows Oakley to create true sculptural contours that stay comfortably flexible. With a rimless design, it's probably the lightest pair of sunglasses you'll ever wear, even though it carries a ton of optical innovation. The unbeatable clarity of High Definition Optics (HDO) has been matched with the finest technologies ever to tame light rays. The Oakley Nanowire blocks UV rays and some models are offered with polarized lenses to block the glare. Oakley's permanent Hydrophobic lens coating repels water, skin oils and dust. Iridium lens coating balances light to optimize vision, and the lenses even have anti-reflective coating on the back side. XYZ Optics maximizes clarity at all angles of view, and the Plutonite lenses filter out all UV.
