KAENON POLARIZED SR-91®
Kaenon Polarized introduced SR-91 as the answer to all of the shortcomings of existing polarized lenses. Glass is heavy and shatters, CR-39 is brittle and not impact-resistant, while polycarbonate offers a dull view and scratches easily. SR-91 was tested in independent labs and confirmed to be the only polarized lens that offers razor-sharp clarity, impact-resistance and glare-reduction all in one ultra-lightweight and durable lens. All of the good. None of the bad.
But our testing doesn’t stop there. Kaenon’s SR-91 lens is constantly relied upon and then validated by the world’s top athletes and adventurers – and it always lives up to the task.
The high-performance, patented Kaenon Polarized SR-91 lens comes standard in everything we make – including prescription. SR-91 Rx is available in Single-Vision and our Freestyle™ Progressive. And every frame is Rx-adaptable.
