Polarized sunglasses made from plant-based plastic. The frame and arms have a high-quality finish and are made from Rilsan Clear G850 Rnew, a material derived from polymers of castor oil. This material is a sustainable alternative to traditional plastic and is also perfect for making lightweight, flexible frames for comfortable-to-wear glasses. The lenses are polarized to block out sunlight, making these glasses ideal for driving or for wearing during outdoor activities in summer and winter. These glasses comply with EN ISO 12312-1 and feature UV400 lenses rated as category 3. Supplied in a 18 x 9 cm soft case, made from recycled PET plastic, which also serves as a cleaning cloth. The glasses are also packaged in a 18 x 8 x 6.5 cm hard case, made from recycled PET plastic.
