The QuattroVarioflex Mirror Visor eliminates reflections, disruptive glare and infra-red radiation. Contours are highlighted, and the tinting automatically adjusts to lighting conditions. QuattroVarioflex is a unique lens technology that has been developed to give winter sports enthusiasts better visibility. The ruby red coloured lens reduces the proportion of blue in visible light: contrasts in the snow are increased, maximising perception. The lens has a brightening effect, allowing the early recognition of contours. Even in poor weather (snowfall, fog, diffuse light), the characteristics of the piste are more easily recognised. The polarisation film integrated into the lens completes the Quattroflex effect. Distracting scattered light and glares are filtered out and the contrast is also enhanced. Reflections and mirroring are minimised, which allows icy surfaces and dangerous situations to be recognised much more efficiently. In combination with Varioflex technology, in which the lenses adapt automatically to the weather, this visor offers a broad variety of uses. The self-tinting (photochromatic) lenses react to visible light. When exposed to radiation, chemical elements "open up" and create a comprehensive darkening effect. When the light intensity decreases, the chemical elements close and the lens becomes brighter again. This process takes seconds.
