As big and bold as the era that inspired it, the Discord proves that a little dissension goes a long way in this large-scale, '80s-inspired piece. Available with Spy Optics revolutionary Happy lens tech and polarization, the Discord is constructed from lightweight yet durable Grilamid and features robust 5-barrel hinges. Spy+'s revolutionary therapeutic Happy lens tech is scientifically tuned to boost mood and alertness while enhancing color and contrast, providing a truly life-changing visual experience. 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 from Grilamid, a lightweight frame material ideal for everyday wear due to its strength and flexibility. Robust 5-barrel hinges for added durability. 100% UV protection reduces eye fatigue and long-term sun damage. Replacement lenses available. The sunglasses have a temple bar length of 4.88" (145mm), with lens (H x W) of 1.65" x 2.24" (42mm x 57mm) and a bridge width (DBL) of 0.67" (17mm).
