TECHNICAL GLASSES FOR HIGH ALTITUDE - ALTAVIA MODEL

The ALTAVIA technical glasses, designed by DEMON, represent the cutting edge in high-altitude and mountaineering equipment, offering uncompromising protection in extreme environments. ALTAVIA combines high-quality materials with a functional and ergonomic design to ensure maximum safety and comfort for outdoor enthusiasts at high altitudes.

Wraparound Design and Total Protection
The ALTAVIA model has been developed with a wraparound shape to protect the eyes not only from sunlight but also from wind, dust, and debris often encountered in mountainous environments. This ergonomic design ensures complete coverage, minimizing peripheral light entry and improving visibility even in the most extreme conditions, such as light reflections on snowy or icy surfaces.

Category 4 Lenses: Maximum Optical Protection
One of the distinguishing features of the ALTAVIA glasses is the category 4 lenses, which offer maximum protection from intense ultraviolet (UV) rays present in high altitudes and on glaciers. Lenses in this category filter up to 95% of visible light, making them perfect for situations where solar exposure is extremely high. At high altitudes, the intensity of UV rays increases, making the use of specific lenses crucial to avoid eye damage, such as corneal inflammation or photoconjunctivitis (commonly known as "snow blindness").

The lenses are made from high-quality polycarbonate, a material known for its lightweight and durability. Unlike glass lenses, polycarbonate does not shatter into pieces upon impact, significantly reducing the risk of eye injuries. This makes it a material also used in safety glasses, ensuring maximum protection against accidental impacts and falls or collisions with hard surfaces during excursions.

Comfort and Safety in Every Situation
Comfort is essential when undertaking long hikes or demanding sports activities. The ALTAVIA glasses are equipped with an adjustable strap that ensures a perfect fit, even during intense sweating or dynamic activities. This adjustment system prevents the glasses from slipping down the nose, maintaining a stable and secure position during climbing, trekking, or alpine skiing.

TR90 Frame: Maximum Lightweight and Durability
The ALTAVIA frame is made from TR90, an advanced combination of nylon and carbon fiber that ensures lightness, flexibility, and strength. This material is up to 20% lighter than conventional materials used in sports eyewear, reducing facial fatigue even after many hours of use. In addition to being incredibly lightweight, TR90 is known for its high resistance to impacts and mechanical stress, making ALTAVIA glasses perfect for tackling the unpredictable conditions of high altitudes.

Another significant advantage of TR90 is its resistance to extreme temperatures. In the mountains, weather conditions can change rapidly, with temperatures varying from very cold to warm, especially when alternating between shaded and intensely sunny areas. The TR90 frame is unalterable at both high and low temperatures, ensuring prolonged durability and maintaining its mechanical properties over time.

Possibility of Fitting Prescription Lenses
One of the great advantages of the ALTAVIA model is the ability to fit prescription lenses directly onto the frame, providing a customized solution for those requiring vision corrections. This feature makes the ALTAVIA glasses ideal for hikers who suffer from visual impairments, allowing them to combine sun protection and visual support in a single accessory.

The option for prescription lenses adds further versatility to the product, enabling users to enjoy perfect and safe vision during outdoor activities without sacrificing the quality and protection of mirrored lenses.

Performance in Extreme Conditions
Category 4 lenses are not just an option but a necessity for those engaging in high-altitude sports. Wearing inadequate lenses in the high mountains can lead to severe visual disturbances. Excessive sun exposure, without proper protection, can cause photoconjunctivitis and other eye problems that may require resting for several hours or even days to allow for recovery. The category 4 lenses of the ALTAVIA glasses not only block almost all ultraviolet rays but also provide a darker tint that ensures superior visual comfort. This tint reduces intense reflections, allowing athletes to focus fully on their path and appreciate their surroundings without visual stress.

Technical Details and Dimensions
Attention to detail is crucial for DEMON, and the ALTAVIA glasses are a perfect example. The dimensions of the glasses are designed to provide maximum comfort and protection for various face shapes:

• Width: 138 mm
• Height: 52 mm
• Arm Length: 126 mm
• Lens Base: 6

These measurements ensure wide coverage and a comfortable fit, essential for those spending many hours outdoors.

The ALTAVIA technical glasses from DEMON are much more than just an accessory: they are an indispensable tool for those facing high altitudes, glacier trekking, or other outdoor activities in extreme conditions. The combination of category 4 lenses, TR90 frame, and ergonomic design offers complete protection and unparalleled comfort, making them the ideal companion for the most demanding athletes.

With the ALTAVIA glasses, DEMON has created a product that merges technological innovation, durability, and functional design, intended to confidently tackle the most challenging challenges that the mountain can offer. If you are a passionate mountaineer or engage in high-altitude outdoor sports, ALTAVIA will ensure you have the necessary protection and comfort to achieve your goals with peace of mind.
