Cascais - Unisex Bio Acetate Sunglasses

The Cascais Unisex Bio Acetate Sunglasses are built on a straightforward premise: wear something well-made that does less harm. Frames are crafted from Italian Mazzuchelli bio-acetate, a material derived from wood pulp and cotton fibers bound with natural plasticizers including citric acid esters, giving each pair a plant-based foundation without sacrificing the weight and finish of conventional acetate. Available in tortoise, olive, black, and gray, the small squared silhouette works across face shapes and wears equally well for men and women.

• Nine-layer lens construction combines four UV400 layers blocking UVA and UVB, two scratch-resistant coatings, two shock-resistant coatings, and one polarized layer for clear, protected vision in varied light conditions.
• CE (EU) and FDA (USA) approved lenses meet verified safety standards on both sides of the Atlantic.
• Compact 48-23-138 fit and replaceable lenses extend the usable life of each frame, reducing long-term waste.

Each pair of Cascais sunglasses ships carbon neutral and comes backed by a two-year guarantee. If you want eyewear that earns its place through material transparency and measurable lens performance, these are worth a close look.
