Just because you're a dirty desert wanderer doesn't mean you can't appreciate a comfortable pair of shades like the Smith Turnkey Sunglasses with polarized ChromaPop lenses. Smith's innovative ChromaPop technology filters out specific wavelengths of light to optimize color definition and perception so you see the beauty of the orange sandstone towers contrasting off the vivid blue sky like never before. The lenses also feature film free polarization that's bonded to the surface without glues for a longer lasting, glare cutting performance under that sunny sky. A hydroleophobic, non reflective, scratch resistant coating on both sides of the lenses protects them from scratches, liquids, and your sunscreen oily fingers, and they eliminate any annoying reflective glares. Smith utilizes recyclable materials in its Evolve frame that make the Turnkey incredibly lightweight. Its design ensures the utmost ventilation while you play out in the hot desert, and hydrophilic Megol pads at the nose and temples prevent any slippage when you start to sweat out there.
