What is a Toric Lens? The horizontal and vertical Base curves are different.

What is an ARC lens? Holly smokes - all these lens questions! In short, it's Spy's optically correct distortion free lens. ARC stands for Accurate Radius Curvature. The lenses become thinner as they move away from the optical center of the lenses thereby eliminating any distortion.

Any warranty? Yep. Spy provides a one year warranty from the date of purchase to replace any product or portion thereof which is deemed a manufacturer's defect.
