A cornerstone of the SPY+ sunglass collection, Crossway pays homage to their unmistakable “cross” icon—classic, designed for everyone, and full of positivity. 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. Frame measures 57-19-142.
