Mountaineering Sunglasses with Photochromic Polarized Cat. 2-4 Mirrored Lenses

For every mountaineer, using technical mountaineering sunglasses is essential for eye protection during expeditions. These sunglasses ensure constant and clear visibility of the path, potential hazards, and changing light conditions.

Choosing the right mountaineering sunglasses allows you to fully experience the mountains with the confidence that your eyes are protected in all lighting conditions, even the most challenging ones. They help maintain perfect visibility of surrounding dangers and, most importantly, where you place your feet.

The OUTDOOR model features Photochromic Cat. 2-4 Polarized Mirrored lenses, representing DEMON's 2021 top-of-the-line innovation that revolutionizes high-altitude mountaineering eyewear. The uniqueness of these lenses lies in the integration of a polarized filter with the exceptional Photochromic Cat. 2-4 lens, enhancing visual contrast and improving the perception of natural colors. With these lenses, you’ll see the trail as if for the first time, every time.

These sunglasses are versatile, suitable for trekking excursions at lower altitudes as well as for extreme mountaineering expeditions at high altitudes and on glaciers. The Photochromic Cat. 2-4 lens dynamically adjusts to changes in light and weather conditions, ensuring that mountaineers always have a clear view of their path.

The mirrored coating not only enhances performance but also provides an appealing aesthetic, making these sunglasses a stylish choice for any outdoor adventure.

Technical Specifications:

FRAME MATERIAL: The OUTDOOR model frame is constructed from TR90 Ultralight, a specialized composite that makes these mountaineering sunglasses 20% lighter than conventional materials. This frame is not only more elastic but also resistant to accidental impacts and stress. Its key features include exceptional resistance to breakage and deformation under both high and low temperatures, which are typical in glacier and extreme high-altitude expeditions. Weighing approximately 40 grams, these sunglasses are designed to be so light that users may forget they are wearing them—an essential principle for DEMON to ensure a perfect fit and allow athletes to focus solely on performance. The frame material, along with the rubber components, is completely hypoallergenic, enabling prolonged use without skin irritation. The OUTDOOR model also includes removable side parts for protection against wind and light, which can be adjusted based on weather conditions or the specific requirements of the path. Additionally, the soft, anti-slip Megol rubber components stabilize the sunglasses on the face, preventing annoying micro-slips caused by walking vibrations or sudden head movements.

LENS MATERIAL: The lenses of the OUTDOOR model are made from durable Anti-Breakage Polycarbonate, recognized as the safest material for sports eyewear lenses. They effectively protect against UV rays (which are stronger at high altitudes) and are resistant to strong accidental impacts. In the event of a significant impact, such as a fall or contact with protruding branches, the lens distributes the shock across its surface, preventing the formation of harmful fragments. This shock distribution occurs immediately, resulting in a "spider web" effect in the lens under severe impact.

Photochromic Polarized Cat. 2-4 Lens Features: The Photochromic Cat. 2-4 lenses start with a light smoke base color and can adapt to reach Category 4 under maximum exposure. The initial light smoke tint allows for adequate visibility even in heavily shadowed areas or very low light conditions. Under optimal light and UV conditions, the lens transitions to Category 4, which is typically used for mountaineering and flying sports, providing optimal eye protection at high altitudes. Like common photochromic lenses, the Photochromic Cat. 2-4 lenses react reversibly to UV radiation and general sunlight, darkening to Category 4 when necessary. When light and UV exposure ceases, the lens gradually returns to its original state. This innovative photochromic lens is specifically designed for mountainous environments, where UV radiation and light intensity are heightened. The goal was to create a dynamic lens for hikers and mountaineers that adapts to every change in light along their path. The starting lens color is a light smoke tint that allows athletes to keep their sunglasses on in low-light areas. At the same time, the Category 2 tint reduces eye glare when transitioning from shaded areas. The lens achieves Category 4 protection only under optimal UV and light intensity conditions, preventing overly dark vision on the trail. This lens can substitute for Category 4 lenses during extreme expeditions (such as Everest, K2, and similar) because it meets Category 4 standards in terms of protection while remaining adaptable to light changes.

Polarized Lens Advantages: The polarized lens not only offers UV protection but also enhances visual comfort. This type of lens can focus or diverge light rays, effectively reducing UV-A and UV-B radiation through a polarizing filter that eliminates lateral reflections. These lenses protect against glare and distracting reflections caused by sunlight bouncing off reflective surfaces like wet asphalt, water, or metal. Originally developed for fishing sports due to their ability to eliminate glare, polarized lenses have since been widely adopted in various water-related sports, representing some of the most eye-friendly options available on the market.

Advantages of Polarized Lenses:

• Enhanced Contrast Perception: Polarized lenses improve the differentiation of colors and details in various environments, enhancing overall visual clarity.
• Sharper Vision: These lenses provide clearer, more precise images, making it easier to navigate challenging terrains.
• True Color Representation: They do not alter natural colors, ensuring that your view remains true to life.
• Elimination of Glare: Polarized lenses effectively reduce distracting transverse reflections from surfaces such as water, snow, and roads.

Polarized lenses excel in mountaineering, particularly under intense UV conditions, providing greater eye comfort and relaxation during prolonged use in bright light.

Accessory Parts (Included with the Sunglasses):

• Adjustable Band: An adjustable strap ensures a snug fit during challenging passages, preventing minor slippage that can detract from comfort.
• Removable Sweat Sponge: This sponge helps to keep sweat from reaching your eyes and blocks side light, enhancing your field of vision.
• Protective Hard Case: A durable case is included for optimal protection against scratches and potential damage to your sunglasses.

DEMON's Mountaineering Sunglasses with Photochromic Polarized Mirrored lenses are ideal for glacier hikes and all high-altitude mountain activities exposed to strong sunlight. They are also excellent for regular trekking outings at lower altitudes.
