CASCADA is made from Polyethylene Terephthalate (PET), a type of plastic found in beverage and textile containers. At Parafina we take care of recycling the PET that comes from uncontrolled landfills to prevent it from reaching the sea. CASCADA is characterized by being a light and water resistant sunglasses. The lenses we use for the CASCADA model (made of polycarbonate) have UV 400 protection (cat. 3) and are polarized, that is, they reduce glare, optical stress and offer better contrast.
