Technologies
Varioflex
Varioflex is a lens technology in which the tint of the lens automatically adjusts to the weather. The self-tinting (photochromic) lens reacts to visible light. When exposed to light, chemical elements open up and create a flat, darkening effect. If the light intensity decreases, the chemical elements close and the pane becomes lighter again. This process takes place in a matter of seconds. The result: a lens for a wide range of lighting conditions.
OPTICAL GLAZING
Spectacle frames with the possibility of direct glazing with prescription lenses.
ADAPTABLE NOSEPAD
Cold-adjustable, rubberized nose pads allow optimal adaptation to any nose width and shape. The rubber coating effectively prevents slippage and ensures a secure fit of the glasses.
FOGSTOP
Fogstop is a coating on the inside of the lenses. The coating is not smooth but rough - even "jagged" on a microscopic level. As a result, the drops have no possibility to form a closed layer, i.e. to fog up and thus obscure the view. This would only happen if the moisture manages to fill the fissures with water. Before this happens, however, the deposited moisture has long since condensed and the view remains clear.
Optimized Airflow
The curved lens ensures that the glasses do not fog up due to indirect air currents.
2 Component Design
Improved wearing comfort is guaranteed by a stable frame and soft material at the contact points of the glasses.
