Kaenon

KAENON has developed a radically new lens material, purpose-built lens tints, and re-engineered polarizing elements.  Additionally, SR-91 PRESCRIPTION lenses are available in Single Vision and in Freestyle Progressive. Ideal for both sport / performance and fashion frame mounts. SR-91's advanced technology ensures that every lens offers high-resolution clarity, light weight and impact-resistance. And every SR-91 lens is guaranteed for a lifetime against delamination, cracking and splitting.
