The lens is made of multiple advanced layers. Beginning with a MLC coating which adds a distinct surface finish for a sleek, high-performance look. To maintain clear vision, an oleophobic coating is used on the outside of the lens which repels water, dirt, dust, and fingerprints, while an anti-fog layer on the inside of the lens keeps your vision clear by preventing sweat and vapour buildup. Lastly, the anti-scratch coating provides essential protection against wear and tear, ensuring long-lasting durability.Pro-level FLUX lens:- The brand-new Valor combines a lightweight frame made of sustainable bio-based material with the pro-level FLUX lens.
