The best sunglasses we have tried. Great for water wear. Scratch resistant
Kaenon introduced SR-91® as the answer to all of the shortcomings of existing lens materials. 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 validated by the world’s top athletes and adventurers as the only lens offering razor-sharp clarity and impact-resistance all in one ultra-lightweight, durable lens. Kaenon’s high-performance SR-91 lens comes standard in every sunglass we make and is available in polarized SR-91 lens options for complete glare elimination. All polarized SR-91 lenses are available in prescription.
