The ALTAVIA model from DEMON is a blend of technology and innovation, designed to ensure maximum eye protection during mountain hikes and mountaineering. Equipped with high-quality photochromic mirrored lenses, these glasses automatically adjust to varying light conditions, shielding your eyes from harmful UV rays and providing optimal vision even in extreme environments.

Photochromic Mirrored Lenses 2-4: Exceptional Adaptability and Performance

The photochromic 2-4 mirrored lenses of the ALTAVIA model are ideal for mountaineering and hiking. These lenses dynamically adjust to the amount of light in your surroundings, offering a flexible defense against sunlight and ensuring maximum visual comfort in any condition.

The base tint of the lenses is a light grey, providing clear and comfortable vision even in shaded or moderately lit environments, such as forest trails or shadowed mountain areas. As the light intensifies, especially at high altitudes, the lenses darken to category 4, offering protection similar to that used for high-altitude and glacier settings.

At their darkest, the mirrored lenses take on a bold red hue, providing effective glare protection while giving the glasses a modern, aggressive look. The mirrored coating further reduces direct sunlight reflection, improving visibility in bright conditions.
