MOUNTAIN GLASSES 2-4 PHOTOCHROMATIC LENSES FOR HIKING AND ALPINISM MODEL NATURE

For those who appreciate mountain walking, it is essential that their eyes are protected. The intense reflection found in high elevation areas can be countered with the right lenses, allowing for the full appreciation of the hike in peace.

Truthfully, using unsuitable lenses at the end of the day may cause constant discomfort as if something was in your eye, or even teary eyes. For maximum protection and performance, DEMON has created a line of mountain glasses with 2–4 photochromatic lenses to protect your eyes with any atmospheric and climatic condition, ensuring a perfect vision.

PHOTOCHROMATIC LENSES 2–4 FOR MAXIMUM EYE PROTECTION:

The 2–4 Photochromic Lenses are extraordinary lenses with a light grey base tone that can reach Class 4 in times of highest activity. The initial light grey allows for proper vision in shaded areas and low–light conditions, and with the best illumination and UV exposure conditions can reach Class 4, typically used in mountaineering.

The photochromic 2–4 lens, exposed to UV radiation and sunlight in general, starts a reversible chemical reaction that darkens the lens surface up to class 4 (if necessary). When the exposure to light and UV radiation ceases, the lens gradually returns to its original color state.

Hiking and Mountaineering: This special photochromic lens was designed with the mountain and the higher presence of UV and Light in mind. The purpose was to create a variable lens for Hikers and Mountaineers that would adapt to any luminosity change of their route. Whether it be in a woody area, or a shaded slope, the lens is designed to quickly lighten and darken, allowing the athlete a constant and perfect vision. The initial tint of the lens is a faint shade of smoke which doesn‘t force the athlete to remove their glasses in dimly lit places. Similarly, Class 2 prevents glare when exiting shady areas. Achieving Class 4 at the peak of effort is affected by the intensity of UV and light. It is important to understand that this particular lens is designed to reach Class 4 only when necessary, thus avoiding too dark of a vision of the trail. This lens can be used instead of Class 4 lenses for extreme expeditions (Everest, K2 and the like) since, in terms of protection, it meets the standards of Class 4, but at the same time is reactive to luminosity changes.

Frame and accessiories

TR90 Frame: DEMON uses a special composition of Nylon and carbon fiber called TR90 to create all their mountain, trekking and alpine eyewear models. It is an allergen–free composition that can be used in extreme conditions for long periods of time without causing skin irritation. The peculiarity of TR90 is its extraordinary flexibility and strength against accidental knocks and mechanical drag, and it is also 20% lighter than frames made with classic materials. Normally, a frame made with this particular composition weighs between 20 and 45 grams depending on the frame thickness. The well–being of the user is DEMON‘s number one goal, and choosing an eyewear with TR90 frame is the best choice for those looking for maximum efficiency and quality materials that guarantee comfort, safety and style. TR90 has a peculiarity known as memory, in fact when it is worn the frame gently adapts to the face and returns to its initial shape when it is removed. This peculiarity is essential, in fact the eyewear also remembers at lower and higher temperatures without deviations. TR90 is also a material with a long life, in fact it has been proven to have greater resistance over time compared to frames made with other classic plastic materials.

Anti-slip rubber parts: The Megol anti–slip portions are made of soft, ultra–light and hypoallergenic material making weight the main feature. These parts are designed to increase the comfort of the eyeglass and prevent any annoying movement down the nose, especially when maximum stability of the eyeglass to the face is needed.

Elastic cord: For the NATURE model, a removable elastic strap is included. Made of flexible material to provide greater comfort and security, even in extreme conditions and on uneven terrain. It also ensures a firmer and more adherent grip on the head, in order to protect the eyes from: air, cold, dust and various debris that the athlete may encounter on his journey.

The NATURE mountain glasses with photochromic lenses for Mountaineering and Hiking guarantee maximum performance without any compromise.
