Thermal mask glass for the Empire EVS mask. The glasses are of very high quality, have a strong, very scratch-resistant surface (as you are used to from Empire glasses) and offer UV protection.
The thermal glasses & their function at a glance:
Clear = clear glass, clear view
Yellow & amber = higher contrast vision, the yellow filters the blue components out of the light. Yellow lenses are also used, for example, by sport shooters. Also darkens a bit.
Smoke & Ninja = Darkened visor, similar to sunglasses. Optimal in very bright light conditions.
HD = Usually an amber lens, darkens slightly and creates a sharper contrast field of view.
Mirror colors = Mirrored from the outside, prevents the player from being recognized under the mask. The sunnier the weather, the better the effect. The glass is slightly darkened, like sunglasses.
