SR-91® Lens Material

SR-91 lens material is the foundation for the finest polarized lenses in the world. SR-91 is made of neither glass, nor polycarbonate, nor CR-39, but a radically new polarized lens material. SR-91 combines the crisp optical acuity of the finest glass lenses, in an ultra light weight, impact-proof lens that exceeds the US Government safety standards of ANSI Z.87.1. COLTS Laboratories, an independent testing facility, has certified Kaenon Polarized SR-91 lenses with an optical acuity and clarity rating of "40" - the highest possible score in the stringent ANSI Z.87.1 testing regimen.

Don't just take our word for it. Look through our Kaenon Polarized lenses and test for yourself. With SR-91 lens material, we have created the next generation of polarized lens technology.

All Kaenon Polarized SR-91 lenses filter out all harmful UV and Blue light.
