Demon Altavia Photochromic 2-4 Lenses mountaineering sunglasses
Demon Altavia Photochromic 2-4 Lenses is a pair of glasses designed for hiking and mountaineering, equipped with photochromic 2-4 mirrored lenses that automatically adjust to brightness. The base tint is light gray, ensuring clear vision in moderately lit or shaded environments, while at high altitudes or under intense light, the lenses reach category 4, darkening and taking on a mirrored red color that reduces glare. This system allows for quick adaptation to light variations without needing to change glasses, always ensuring protection and visual comfort.
The frame is made of TR90, a combination of nylon and carbon fiber that provides lightweight, impact resistance, and stability even in the presence of thermal fluctuations. The Megol inserts on the temples and nose bridge ensure a non-slip grip, keeping the glasses secure during intense movements or sweating. The model also allows for the fitting of prescription lenses, making it suitable for those who require vision correction.
The dimensions are 138 mm in width, 52 mm in height, and 126 mm in temple length, with a lens base of 6, ensuring a stable fit on various face shapes. The glasses weigh 22 grams, offer UV400 protection against UVA and UVB, and include a hard case and a microfiber pouch. The unisex design makes them suitable for mountaineering, hiking, skiing, and other multisport activities, with additional side parts for light protection.
