Be Wilder-at least that's how Spy Optics says it-is a rallying cry to express yourself, to never hold back and let yourself be free. Slim, square, and vintage design has been an icon at surf breaks, ski slopes, music venues, and movie sets over the years. Bewilder sunglasses are happy to carry on the tradition. ARC (Accurate Radius Curvature) polycarbonate lenses are tapered to follow the natural curvature of the eye, providing crystal-clear distortion-free vision while reducing eyestrain. Available with polarization, which blocks over 99% of surface glare and is layered and sealed within Spy's lenses to prevent scratching, delaminating, and hazing of your polarized filter. Constructed of bioplastic, which is comprised of 50% organic plant matter that is both lightweight and durable and aids in reducing plastic consumption. Snap hinges provide a secure, comfortable fit. 100% UV protection reduces eye fatigue and long-term sun damage. The sunglasses have a temple bar length of 5.83" (148mm), with lens (H x W) of 1.77" x 2.13" (45mm x 54mm) and a bridge width (DBL) of 0.79" (20mm). Sunglasses come with a microfiber protective pouch with drawstring closure for storage, cleaning, and transport.
