The "Category - CAT" number determines the light transmission rate (light transmittance) in the visible range. How well and clearly you can perceive your surroundings depends primarily on the lens you choose.
Lens HAWK
Above all, sports glasses have one important function: protecting the eyes. The lenses of the HAWK have a UV400 protection. This filters and blocks dangerous UVA and UVB rays. The lenses are also equipped with a Nano-HD coating to detect contrasts in all lighting conditions and to deflect water drops on the lens.
In order to be able to adapt to changing light conditions as quickly as possible, the sports glasses are equipped with a simple plug-in system. The lenses can be exchanged within a few seconds .
