Rislan® Clear Rnew® G850

Rislan® Clear Rnew® G850 is a high-performance, bio-based polyamide material from Arkema. The G850 material contains 45% bio-based carbon made of Castor beans. These beans are extracted from plants and converted into oil which forms the basis for bio-based Polyamide. It is specially designed for injection moulding applications and ideally suited for frames of high-end eyewear. This makes the material of these glasses not only more durable, but also lightweight, flexible and virtually unbreakable.

Photochromic lenses

Photochromic lenses

Our photochromic lenses for cycling glasses are designed to automatically adapt to changing light conditions. They darken when it's bright outside and become virtually clear in low-light conditions. With a unique range of available light, our lenses allow for optimal visibility, adjusting from 85% to 17% light transmission.
