Made from premium materials, RAEN sunglasses are designed in California using a unique and customer acetate combination, with every frame built with hand guided cutting and hand polished to finish. Lenses are manufactured by Carl Zeiss Vision, these industry leading lenses provide 100% UVA/UVB protection and can be swapped out for prescription lenses to transform your optics. Opticians prefer to work with handmade acetate frames as they can be heated and moulded to achieve the optimum fit. This high grade acetate originates from renewable sources of wood pulp and natural cotton fibres, retaining its colour brightness as the hue is embedded in the material, not sprayed on. The acetate in all RAEN sunglasses also contains ageing stabilisers that prevent fading, yellowing or discolouration from UV light or skin contact.
