Bio Based

Ray-Ban’s Bio‑Based eyewear collection uses a more sustainable material mix — replacing petrochemical components with plant-derived sources like cotton, wood pulp, cereals, beet, sugar cane, and castor oil. Here’s what you should know:

Bio‑Acetate frames (e.g. Wayfarer, Warren, Kiliane models) contain about 67% bio-based carbon, cutting CO₂ emissions by over 50% compared to standard acetate  .

 

Bio‑Nylon lenses (like in the Xan) have a minimum 40–60% plant-based content, derived mostly from castor oil  .

Even packaging—cases, pouches, and boxes—is eco-friendly, often made of recycled paper or fiber, sparking some curiosity—see Reddit users discussing the cork-like texture .
