Demon Nature Photochromic 2-4 Lenses sports sunglasses

Demon Nature Photochromic 2-4 is a mountain eyewear designed for hiking and mountaineering, equipped with red mirrored photochromic lenses 2-4. At high altitudes, light intensifies and reflections increase, which is why it is essential to use specific lenses: inadequate models can cause irritation, tearing, or prolonged discomfort. The photochromic lenses designed by DEMON offer optimal protection and clear vision in all weather and lighting conditions.

The 2-4 red mirrored lens starts from a light gray tone and automatically adjusts to the amount of light, reaching category 4 during peak exposure. The external mirror reduces glare and enhances contrast in very bright environments. The reaction to sunlight occurs through a reversible chemical transformation: the lens darkens quickly with increased UV rays and gradually returns to the initial tone when brightness decreases. This behavior makes it suitable for both shaded areas or forests and intensely lit slopes, without the need to remove the glasses. It is designed to meet category 4 standards even in the most extreme situations, making it suitable for high-altitude expeditions.

The frame is made of TR90, a combination of nylon and carbon fiber that ensures lightness, strength, and flexibility, remaining comfortable even during prolonged use. It retains the memory of the original shape even in extreme heat or cold conditions. The soft, non-slip Megol inserts improve stability during intense activities, while the removable elastic cord provided adds security on uneven terrain and in exposed conditions, protecting against external elements like air, dust, and debris.

The dimensions are: width 140 mm, height 50 mm, temple length 134 mm, with lens base 8.
