The frame is made from bio-based material, which is kinder to the environment and feels just as comfortable as regular acetate frames. These sunglasses feature dark green lenses that offer 100% UV protection, while maintaining the iconic rectangle shape that has been loved by generations. Wear them in black with polished finish for an easy-to-match style that will never go out of fashion.
