DMN ALTAVIA, 4 cat.

The ALTAVIA technical glasses, designed by DEMON, represent the cutting edge in high-altitude and mountaineering equipment, offering uncompromising protection in extreme environments. ALTAVIA combines high-quality materials with a functional and ergonomic design to ensure maximum safety and comfort for outdoor enthusiasts at high altitudes.

Category 4 Lenses: Maximum Optical Protection
One of the distinguishing features of the ALTAVIA glasses is the category 4 lenses, which offer maximum protection from intense ultraviolet (UV) rays present in high altitudes and on glaciers. Lenses in this category filter up to 95% of visible light, making them perfect for situations where solar exposure is extremely high. At high altitudes, the intensity of UV rays increases, making the use of specific lenses crucial to avoid eye damage, such as corneal inflammation or photoconjunctivitis (commonly known as "snow blindness").

The lenses are made from high-quality polycarbonate, a material known for its lightweight and durability. Unlike glass lenses, polycarbonate does not shatter into pieces upon impact, significantly reducing the risk of eye injuries. This makes it a material also used in safety glasses, ensuring maximum protection against accidental impacts and falls or collisions with hard surfaces during excursions.
