Collection: Prescription Sports Glasses with Category 4 Smoke Lenses

PRESCRIPTION SPORT GLASSES CATEGORY 4 LENSES


Anyone who lives in the mountains and experiences its unique characteristics understands the importance of using the right equipment to be fully prepared for every excursion.

Protecting your eyes is crucial due to the higher solar intensity and stronger UV rays found in mountainous regions. For those who wear prescription lenses daily, DEMON has created prescription sports glasses featuring category 4 lenses specifically designed for mountaineering, ski mountaineering, and hiking.

These glasses are thoughtfully designed to meet the needs of trekkers and mountaineers: they have an ultra-light frame that is resistant to both high and low temperatures, a removable sweat sponge, an adjustable and removable elastic cord, and category 4 lenses that provide optimal protection in mountainous and high-altitude conditions.

The prescription sports glasses with category 4 lenses are suitable for normal hiking and trekking, as well as for mountaineering and ski mountaineering. These lenses, darker than standard category 3 smoke lenses, are particularly beneficial for those who are sensitive to intense light.

A standout feature of these glasses is a special attachment in the frame that allows for the insertion of an optical clip, accommodating corrective lenses. This innovative technology enables individuals who require prescription lenses to pair them with technical lenses designed for mountainous conditions. Graduating a curved lens based on a typical sports frame (usually category 8) can be quite expensive. In contrast, solutions with optical clips are both economical and high-performing.

Technical Characteristics of Prescription Sports Glasses with Category 4 Lenses:

  • Category 4 Lenses: These technical lenses are specifically designed for mountains and mountaineering. With a smoke tint, they provide optimal eye relaxation even in very bright conditions and during prolonged use. Prescription sports glasses with category 4 lenses can also be used for trekking at lower altitudes, skiing, and other activities for those particularly sensitive to strong sunlight.

  • Versatile Use: Beyond mountainous contexts, category 4 lenses are recommended for all sports that involve extended exposure to intense sunlight, including sailing, navigation, paragliding, and flying.

    • Shatterproof Lenses

      A key feature of prescription sports glasses with category 4 lenses is their shatterproof nature. DEMON lenses are made from high-quality, impact-resistant polycarbonate. These lenses are not only lighter than those made from conventional materials but also more resistant to accidental impacts, enhancing safety.

      In the event of a strong impact, the lens distributes the shock evenly across its surface, creating a spiderweb effect that prevents breakage. This design ensures that no harmful fragments are generated, protecting the eye from potential injury.

      Optical Clip

      The optical clip technology allows the combination of prescription sports glasses with category 4 lenses, effectively merging mountain eyewear with prescription functionality.

      The clips are designed to fit into specially allocated slots within the close-fitting frame, allowing for customization based on individual preferences. This versatility means you can use the prescription sports glasses with or without the clip, which is especially useful if you prefer wearing contact lenses during your activities. The clip can also be utilized with or without the sweat sponge.

      Crafted from the same material as the frame, the optical clip ensures elasticity and resilience, even in extreme temperatures.

    • Ultralight and Elastic Frame

      All prescription sports glasses with category 4 lenses are crafted from TR90, a unique composition of nylon and carbon fiber that makes the glasses 20% lighter than those made from conventional materials. These glasses are not only more resistant to accidental impacts but also better able to withstand extreme temperatures without breaking or deforming. TR90 is a hypoallergenic plastic with "memory," meaning that when worn, the glasses contour gently to the head and return to their original shape once removed.

      Accessories

      The OUTDOOR model with category 4 lenses includes two specialized accessories that are essential for mountaineering, distinguishing technical glasses from regular mountain eyewear.

      Removable Sweat Sponge: This crucial component prevents sweat from reaching the eyes and protects the athlete from wind by creating a lateral barrier. Additionally, it helps block light from filtering in from the sides.

      Adjustable Elastic Cord: This accessory is equally important as the sweat sponge. It enhances the stability of the glasses on the face and provides support to prevent loss when the glasses are not in use. The elastic cord is also customizable to suit individual preferences.
