The injected thermal lens for the CLK provides 100% UVA, UVB, UVC protection and is optically corrected for superior clarity. The lenses are also 4D Coated with permanent Anti-Fog and Anti-Scratch coatings for performance and longevity. Selected lenses have a Polarized Dytanium or Dytanium coating to reduce glare and balance light transmission. Unlike many lenses on the market ours is not a flat sheet pressed into a curve. Instead we use a process where our lenses are injected which creates a much more even spread of the material and ensures optical clarity.
