Which Ray-Ban collection uses bio-based materials introduced in 2020?

The Ray-Ban collection using bio-based materials is Ray-Ban Bio. Ray-Ban’s current product pages often style the name as “Bio-Based,” but “Ray-Ban Bio” is the accepted shorthand for the same sustainability-focused line.

The collection applies alternative materials to familiar Ray-Ban silhouettes. Depending on the model, frames can use bio-acetate, bio-based nylon, or bio-based rubber. These materials incorporate biological sources such as cellulose, castor oil, or plant-derived ingredients rather than relying entirely on fossil-based feedstocks.

Ray-Ban also describes bio-based nylon lenses for non-polarized sunglasses. The company says these lenses contain at least 40% biological content, while some bio-based nylon frames contain at least 57% bio-based content. Polarized lenses have historically had different material limitations, so not every treatment uses the same formulation.

“Bio” does not mean that every part of every pair is biodegradable or plant-made. It describes selected materials and components within the collection. The line therefore combines Ray-Ban’s established shapes with a reduced-fossil-material approach rather than representing a completely different eyewear technology.
