We took the same material that is used in bulletproof glass and astronaut helmets, then injected it into moulds that are perfectly formed for optical clarity, mitigating any concerns of shattering on impact. But it’s not the material on its own that makes for great sport lenses. The manufacturing methods, tints, finishing, coatings, and even how they fit into their frames all play important roles in the optical quality, clarity and durability of a Polycarbonate lens.

All RYDERS lenses use premium coatings and finely-tuned tints. They are rigorously tested, not only for their optics but for their durability, both in the lab and the real world. These lenses come in every pair of RYDERS, and this high standard is just our starting point. Polarized, Photochromic, PolarPhoto, veloPOLAR™ and antiFOG lenses have all the attributes listed here plus their premium features that take them to that next level of performance.
