Conductive antistatic layers and super hydrophobic topcoats are just some of the many layer applications used in lens treatments. Multi K, and Bluefree K Plus are used to treat lens layers in Xera® Lenses.
Blue light Digital Protection
As the widespread use of smartphones and tablets increases, people are exposed to more blue light today than ever. Out digital devices emit intense blue light, which scatters easily, reducing contrast and adding eye fatigue.

BlueFree is designed to block harmful blue-violet light whose wavelength ranges between 380-455 nm.
