A champion of knockout style and cutting-edge optics, the Spy Rocky Polarized Sunglasses pair bold, sweeping lines with visual acuity on the brightest days of the year. Polarization kills blinding glare off alpine snowfields and white sand beaches, and Happy Lens technology allows long-wave blue light through the lens to reduce eye fatigue and keep your outlook up. To ensure maximum protection, this lens technology blocks harmful UV radiation and short-wave blue light. Striking the sweet spot between lightweight comfort and strength, the grilamid frame stands up to rigorous use and abuse in the outdoors. Hytrel nose and temple pads retain a secure fit without migrating or slipping off your face, even when you're sweating. As a handy bonus, the temple tips feature small cutouts for attaching a leash.
