Product description



The passion for mountains has deep roots. The rustling of the wind in the trees, the sound of our steps along the path, the solidity of the stones underfoot, and the sense of freedom we cherish in nature, culminating in the satisfaction of reaching the summit. For those who love high-altitude mountaineering, protecting one's eyes is of primary importance and cannot be overlooked. It is well known that in the high mountains, mountaineers need not only category 4 lenses that effectively protect from UV rays (stronger than at lower altitudes) but also from the intense light directly and reflectively from ice and snow. DEMON has created a line of mountain glasses with category 4 lenses for mountain lovers, enthusiasts, and outdoor adventurers. For eye health and protection, DEMON ensures you can focus solely on what truly matters: your journey and experiences.





Category 4 lenses are technical lenses recommended for high-altitude hiking and mountaineering. They are particularly suitable for use on glaciers, where strong snow reflection and the monochromatic white of ice can be very irritating without the right lenses. Additionally, category 4 lenses can be used outside of mountain environments for very intense light conditions and for those particularly sensitive to light.



Hiking and Mountaineering: As described, the category 4 lens is designed for use in the mountains for hiking and mountaineering. Its construction effectively protects the eye from all UV-A and UV-B rays, which become much more intense at higher altitudes due to reduced atmospheric shielding. Consequently, the sun’s rays and light intensity are greater, making category 4 lenses the best choice for ensuring constant eye comfort, even with prolonged use. Extreme mountaineering expeditions require the best technology for all necessary equipment. For eye protection, the category 4 lens or the photochromic lens 2-4 (which reaches category 4 when light and UV intensity thresholds are exceeded) are recommended to avoid severe eye irritation that could interrupt the expedition. It’s also important to note that above a certain altitude, snow masks are used instead of light protection to cover more of the face, preventing frostbite (applicable to extreme expeditions like Everest, K2, and high-altitude peaks).



  • TR90 Frame: The TR90 frame is made from a special blend of nylon and carbon fiber used by DEMON for all mountain eyewear frames. It is hypoallergenic and suitable for extreme conditions, even with prolonged use, without causing skin irritation. TR90 is exceptionally elastic and resistant to impacts and mechanical stress, and is 20% lighter than conventional materials. A frame built with this material typically weighs between 20 and 45 grams, depending on the thickness. Performance is DEMON's top priority, making the TR90 frame the choice for those seeking maximum performance, comfort, safety, and aesthetics. The TR90 has a memory feature that allows it to adapt gently to your face’s shape and return to its original state when removed, maintaining its shape even at extreme temperatures. It also has a longer lifespan, demonstrating greater resistance over time compared to frames made from other conventional plastics.
  • Non-slip Rubberized Parts: Made from soft, non-slip Megol, an ultra-light, hypoallergenic material, these parts enhance comfort and prevent annoying slips towards the nose, especially in critical areas where maximum stability is needed.
  • Sweat Sponge: The sweat sponge is made from high-density hypoallergenic material and is essential for mountaineers. It performs multiple functions:
    • Sweat Prevention: Prevents sweat drops from reaching the eyes during intense activities.
    • Air and Debris Protection: Blocks air and debris (e.g., dust) from contacting the eyes.
    • Light Protection: Prevents lateral light rays from reaching the eyes, ensuring clear vision. The sponge is removable and can be used according to the mountaineer’s needs.
  • Elastic Cord: The EIGER model includes a removable elastic band made of flexible material, enhancing comfort and stability during critical conditions and difficult terrain. It keeps the glasses stable and close to the face, effectively protecting the eyes from air, cold, dust, and debris encountered on the journey.



The mountain glasses with category 4 lenses for mountaineering and hiking guarantee maximum performance without compromise. The measurements of the EIGER glasses are: Width: 140mm; Height: 50mm; Rod Length: 125mm; Lens Base: 8. Products are always shipped in their original packaging. For some models, the color or shape of the case may differ from what is shown.
