- Z-Vario lenses are photochromic lenses with progressive darkening. The intensity of the sun filter varies automatically according to the ambient light and the lens quickly becomes dark and quickly clear as the intensity of the light increases and decreases.

- The ZIEL IR-proof lenses allow you to significantly reduce the intensity of infrared rays, which can penetrate the eye tissues causing significant damage to the lens. They protect the retina from irreversible damage. They absorb the IR-A rays that hit the eye, reducing thermal damage to the lens and retina.

- ZIEL UV-proof lenses are designed to offer the eye maximum protection from ultraviolet rays, ensuring clear and perfect vision.
