Glass wasn’t strong enough. Polycarbonate wasn’t clear enough. Neither material allowed for adequate customization of tints and Light Transmission Levels. So we set out to develop our own, completely new lens material. Kaenon’s proprietary SR-91 is the only lens material that combines the superior optical quality of the finest glass and the lightweight, strength and impact resistance of polycarbonate. All of the best properties. No compromises. No short-cuts.

SR-91 was created with performance in mind – requiring extreme light weight and impact-resistance, for the ultimate protection from more than the sun. SR-91 exceeds ANSI Z.87.1 standards for high impact resistance. Paired with Glare 86®, Kaenon’s exclusive and proprietary polarizing element, our proprietary polarized lens technology reduces glare up to 99.9% and provides complete protection against all harmful UV rays. At an incredible 30 microns thin, Glare 86 is completely encapsulated inside the lens. Ultra-lightweight and thin, our SR-91 material has a naturally high strength-to-weight ratio. This translates into superior comfort when worn for extended periods of time. Additionally, SR-91, despite its lightweight properties, is an extremely durable lens material which features superior scratch-resistance as compared to polycarbonate lenses, providing razor-sharp clarity.
