Product description



For those who relish hiking in the mountains, protecting your eyes is paramount. The intense glare encountered at higher elevations can be effectively countered with appropriate lenses, ensuring a serene and enjoyable trek.


Using unsuitable lenses can lead to persistent discomfort by day's end, akin to having debris in your eye or even excessive tearing. For utmost protection and performance, DEMON has innovated a line of mountain glasses featuring 2-4 photochromic lenses, safeguarding your eyes under any atmospheric and climatic conditions while providing impeccable vision.



The 2-4 photochromic lenses are exceptional, starting with a light gray base that can darken to Category 4 during intense UV exposure. Initially, the light gray tint ensures clear vision in shaded or low-light areas, while adapting seamlessly to brighter conditions and UV exposure by darkening to Category 4. This capability is particularly beneficial for mountaineers, as it adjusts to varying light intensities encountered during their journey.


These lenses react to UV radiation and solar illumination with a reversible chemical reaction, darkening in response to light and UV rays and gradually returning to their original state when exposure diminishes.


Ideal for Hiking and Mountaineering:

Crafted specifically with mountainous environments in mind, these photochromic lenses provide versatile adaptability to light variations throughout your trek. Whether traversing through dense forests or scaling sunlit slopes, the lenses swiftly adjust, ensuring consistent and clear vision.


The initial light smoke tint of the lenses avoids the need to remove glasses in low-light conditions, while Category 2 provides glare protection upon emerging from shaded areas. The transition to Category 4 during peak sunlight and UV exposure ensures optimal eye protection without excessively darkening your vision unnecessarily.




TR90 Frame: The NATURE glasses feature a TR90 frame, a composite of Nylon and carbon fiber chosen for its hypoallergenic properties and exceptional durability in extreme conditions. It's allergen-free and ideal for long-term wear in challenging environments without causing skin irritation. TR90 is renowned for its flexibility, lightweight nature (20% lighter than traditional materials), and memory properties, molding comfortably to your face and retaining its shape across varying temperatures.


Non-Slip Rubberized Parts: Soft, ultra-light, and hypoallergenic Megol rubberized parts ensure comfort and prevent slippage, particularly during high-intensity activities where stability on the face is crucial.


Elastic Cord: Included with the NATURE model is a removable elastic strap, designed for enhanced comfort, safety, and a secure fit in extreme conditions and rugged terrain. It provides additional protection against wind, cold, dust, and debris encountered during your adventure.
