The polycarbonate normally used in the eyewear sector is limited by its poor scratch resistance, hence the need to find a solution through our surface treatments: anti-scratch which increases abrasion resistance and thus the product's life, and anti-fog that meets safety requirements in sports and industrial products such as swimming goggles, work goggles and electrical equipment visors. The polycarbonate used in the optical sector has a limitation in terms of scratch resistance. Hence the need to find a solution through our surface treatments: the anti-scratch treatment enhances abrasion resistance, thereby extending the product's lifespan. The anti-fog treatment meets safety requirements in sport and industrial products such as swimming goggles, work masks and electrical equipment visors.
