This material (PET) is used in the production of packaging and textiles. With these sunglasses, made with 3 bottles of this plastic, we prevent this type of waste from reaching the sea. The main characteristics of the sunglasses that make up this collection are that they are waterproof and ultra light. The lenses are polarized and have UV 400 protection (cat. 3). Polarizing reduces glare, optical stress and contrast.
