Collection: Mountain Bike Glasses

MTB GLASSES

Mountain biking is a globally recognized and beloved discipline, synonymous with pure adrenaline, speed, dust-kicking, jumps, and vibrations. Every professional rider or MTB enthusiast continually seeks to enhance their performance and push their limits.

DEMON has developed a line of MTB glasses crafted with cutting-edge materials to ensure perfect and consistent visibility on the route while providing maximum eye safety.

Every rider looks for high-performance materials and technologies to enjoy their outings while elevating their performance in total safety.

All riders, whether professional or amateur, share some essential needs for eye protection:

• Perfect visibility in changing light conditions
• Impact resistance
• Maximum stability of the glasses
• Ergonomics and lightweight design

DEMON MTB glasses are designed and constructed with these four fundamental characteristics in mind, distinguishing them as technical eyewear specifically for mountain biking rather than just ordinary sports glasses.

Why Are These Requirements So Important?

We will now explain the four fundamental requirements on which DEMON's design and creation of MTB glasses are based:

1. Perfect Visibility in Changing Light Conditions

Mountain biking often involves frequent transitions between light and shadow, such as entering tunnels, forested areas, or shaded terrain. These changes can force riders to slow down or even momentarily halt their activity due to difficulties in seeing the route ahead. This not only causes frustration but also detracts from the enjoyment of the ride.

Selecting high-performance MTB glasses is crucial to effectively tackle such situations. The ideal lenses for optimal performance and safety are photochromic lenses. Made from high-quality polycarbonate, these lenses offer outstanding optical clarity and are virtually unbreakable, providing maximum protection against impacts from debris like leaves, branches, stones, and insects.

Photochromic lenses undergo a reversible chemical reaction when exposed to UV radiation or sunlight, causing them to darken. When light exposure diminishes, the lenses gradually return to their transparent state. For instance, when entering a shaded area like a tunnel or dense forest, the lens reverts to its non-darkened state, offering protection against airborne particles. Upon exiting the shaded area, the lens resumes the darkening process, reducing glare and enhancing visibility in bright light conditions.

This dynamic lens technology continuously adjusts to changes in light conditions, ensuring perfect and consistent visibility for the athlete. There are two types of photochromic lens technologies available for MTB glasses, each catering to specific rider needs and significantly enhancing performance and safety:

DCHROM Photochromic Lens: This advanced photochromic lens features a slightly darker base color, reaching category 3 darkness (similar to sunglasses with mirrored lenses) during maximum activation. Notable for its rapid transition between light and dark states, it provides remarkable eye relaxation, particularly on days with intense sunlight. This lens is recommended for riders navigating dense forests while also traversing open spaces, where prolonged use of lighter lenses may prove cumbersome. However, it may become too dark for nighttime use, for which the Smoke photochromic lens is recommended.

Smoke Photochromic Lens

This particular photochromic lens differs from the DCHROM lens in its coloring during the phase of maximum transparency. It initiates the same chemical reaction that darkens the lens when exposed to sunlight. However, in addition to starting out lighter, it remains half a shade lighter at maximum activation.

This special photochromic lens is particularly suitable for riders who frequently encounter long stretches of dense forest, those who often ride at dawn and sunset when light is low, and especially for those who engage in night excursions where a completely transparent filter is needed for protection against airborne debris like dust, leaves, branches, and other projections.

For MTB riders with these specific needs, we recommend choosing this type of lens to avoid any potential inconveniences arising from poor visibility on the route.

IMPACT RESISTANCE (Lenses)

Another fundamental aspect of the design of MTB glasses is the selection of safe and unbreakable materials. Mountain biking, being the cycling discipline that requires the most protection for the rider, demands cutting-edge materials for total eye safety. Shatterproof polycarbonate lenses have been specifically created for eye protection, capable of withstanding even strong impacts effectively.

The key feature of polycarbonate lenses used in all MTB glasses lies in their elasticity and durability. In the event of a strong impact, the lens distributes the shock across its entire surface, completely preventing the formation of small fragments that could harm eye health. Instead, it creates a "cobweb" effect that renders the lens unusable.

Using polycarbonate not only reduces the weight of MTB glasses but also significantly enhances safety for the rider's eyes.

In the following photos, you will see the results of tests conducted on polycarbonate lenses, which were subjected to strong and repeated impacts with a steel hammer to simulate accidents. The lenses did not break; instead, they deformed in some areas to absorb the impact. Ensuring the best possible protection for the athlete's eyes is the cornerstone of DEMON's lens design across the entire collection.

IMPACT RESISTANCE (Frame)

The frame of the MTB glasses is designed to be impact-resistant and is made from TR90, a special blend of nylon and carbon fiber. This combination makes the glasses 20% lighter than conventional materials while also enhancing their resistance to accidental impacts and mechanical stress. The nylon component provides excellent elasticity and increased durability, ensuring that the glasses remain non-deformable at both high and low temperatures. This design ensures longevity and reliable performance over time.

MAXIMUM STABILITY OF THE GLASSES

TR90 plays a crucial role in ensuring the stability of MTB glasses. When worn, the glasses conform effectively to the wearer’s head without feeling tight, returning to their original shape when not in use. A snug fit provides greater stability, especially during the strong vibrations and sudden movements typical of mountain biking.

Additionally, the rubberized parts of the frame, made from soft non-slip Megol, further enhance stability and prevent any minor slips. With the glasses offering total stability, you can confidently tackle even the most extreme and bumpy routes. The design also distributes weight evenly, preventing any imbalance toward the tip of the nose. Every detail is meticulously crafted to ensure maximum performance.

ERGONOMICS AND LIGHTNESS

An often overlooked aspect is the choice of construction materials for the frame. The shape of each pair of glasses is meticulously designed to provide absolute comfort. TR90 and Megol are ergonomic, hypoallergenic materials that ensure maximum comfort, even in the most extreme conditions.

Choosing stable glasses that offer total comfort is crucial when selecting your MTB eyewear. Wearing uncomfortable or heavy glasses for extended periods can distract or annoy the rider, significantly reducing performance.
