Lens Aeration System


Special DEMON lenses with ventilation system through aeration holes created on the lens, which increase comfort in any climatic situation and reduce the internal humidity that generates fogging.

It is important to distinguish that glasses with ventilation holes and snow goggles are present in the DEMON collection. This technology is generally applied to models with a very wide lens that need more air to prevent fogging.

Snow goggles for Ski and Snowboard:

As far as snow goggles are concerned, the entire collection is equipped with Double Lenses with Anti-Fog Treatment, technologies aimed at contrasting and preventing the creation of condensation in the inner surface of the lens. However, for models with wider lenses where these two technologies combined with the aeration of the frame are not 100% performing, holes are created in the surface of the lens to increase ventilation and air recirculation.

To prevent snow or water from entering between the 2 lenses, there is a spongy part to protect the holes.

Sports Prescription Glasses and Vista Sport Glasses:

Lens Areation System for prescription sport glasses

The same concept is repeated for sports glasses, in fact where the function is not enough to prevent the airing (due to aerodynamic shape or very large lens) there are holes or grooves in the lens surface. This technology effectively counteracts fogging even in conditions of low air circulation by providing a constant feeling of relaxation for the eyes.
