Rilsan® Clear Rnew® G850

Rilsan® Clear Rnew® G850

Rilsan® Clear Rnew® G850 is a high-quality plastic derived from plant-based materials, produced by manufacturer Arkema. The G850 variant consists of 45% bio-based carbon made from castor beans. These beans are harvested from plants and processed into oil, which serves as the foundation for bio-based fiber polyamide. This material is particularly well-suited for high-end eyewear frames, making the glasses not only more sustainable but also lightweight, flexible, and virtually unbreakable.

Smart choice

We assign the smart choice label to products in consultation with our manufacturers. We assess the certifications and/or features, and we place the label if a product meets our criteria. Products with the smart choice label have sustainability benefits compared to similar products. These products are a 'smart choice' because they are sustainable in design, packaging, materials, or a combination of these.

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.
