REACTIV lenses:
the essential technology

Whether you’re a trail running enthusiast, passionate cyclist, or avid hiker, REACTIV photochromic lenses guarantee optimal protection and uncompromised visual performance. So, ready to fully live each moment, no matter the light?

What is a REACTIV photochromic lens?

REACTIV photochromic lenses embody the ultimate technological expertise in visual protection for outdoor sports enthusiasts. Thanks to advanced photochromic technology, these lenses adjust their tint based on ambient UV light, providing precise and secure vision in all conditions. This isn’t just a surface treatment: made by casting, the lenses feature a photochromic treatment integrated into the lens material. The result: high-performance, long-lasting photochromism, guaranteed for life. This technology ensures fast and reliable adaptation to changes in light.

What are the features of REACTIV photochromic lenses?

The strength of REACTIV photochromic lenses lies in their unique properties, designed to meet the needs of the most passionate athletes. They are built to last: lightweight, scratch- and impact-resistant, while offering optical quality. It’s not just about comfort, but about performance. In sometimes extreme environments where safety depends on good visibility, REACTIV photochromic lenses are essential.

Their ability to adapt quickly to changing weather makes them a top choice for those who never want to lose sight of their goals. With REACTIV lenses, seeing clearly and far is not a luxury—it’s a necessity. From shadow to bright light, they keep pace with you, letting you focus on what really matters: your passion.

The difference between REACTIV photochromic lenses and standard lenses

Unlike standard lenses that maintain a fixed tint and don’t react to light changes, REACTIV photochromic lenses adjust their tint in real time. This responsiveness—critical for demanding sports like mountaineering or trail running—ensures sharp vision without manual adjustment. No more having to move, adjust, or remove your glasses. This photochromic integration isn’t a surface coating but a controlled process, ensuring long-lasting performance. You can fully enjoy your adventures with uncompromised visual comfort.

Which REACTIV photochromic lenses to choose for your sport?

The REACTIV photochromic lens range was specially developed to meet the needs of each sport. From enhanced contrast to polarized lenses, each model addresses the visual challenges posed by the environments you face. Discover the recommended REACTIV lenses for the most popular sports and benefit from optimized vision tailored to your needs:

Mountain sports and high-altitude (mountaineering, hiking)

REACTIV lenses were specially designed for the demands of mountain and high-altitude sports, especially the changing light conditions in these environments. Their ability to instantly adapt provides optimal protection, clear vision, and exceptional comfort whether hiking, mountaineering, or on expedition in extreme terrain.

• REACTIV 2-4: combines a brown-yellow base with rapid activation to adapt to light changes. With a silver or blue external flash option, it offers excellent depth perception and visual comfort—perfect for mid-altitude activities or variable lighting environments.
• REACTIV 2-4 Polarized: includes a polarizing filter in addition to a wide photochromic range. This filter eliminates glare from surfaces like snow or water, providing enhanced glare protection. The brown base and dark brown flash enhance contrast for precise vision—ideal in bright, technical environments.
• REACTIV 0-4 High Contrast: the premium choice for extreme conditions. These lenses range from clear (when inactive) to dark red when fully activated. They improve depth perception, help anticipate obstacles, and ensure safe progress—even in areas shifting between shadow and bright light. Ideal for sunrise ascents or nighttime descents.

Trail running and cycling

Trail runners and cyclists know how light can vary along their routes—moving between sun and shade. For these sports, REACTIV 1-3 Light Amplifier lenses are ideal, with a tint suited for low-light or wooded environments. They amplify light and reveal details softly. Lightweight and responsive, they ensure clear, sharp vision, helping you anticipate turns and obstacles with clarity. These lenses let you focus fully on your performance without adjusting your glasses.

Nordic skiing and mountain biking

In Nordic skiing and MTB, where terrain detail is crucial, REACTIV 1-3 High Contrast lenses with a pink base are highly recommended. This tint boosts contrast and enhances relief definition for more precise perception—especially in low-light or overcast conditions. These lenses help detect terrain variations with increased precision.

Why are REACTIV photochromic lenses essential for demanding athletes?

REACTIV photochromic lenses are the obvious choice for those practicing outdoor sports with intensity and precision. Designed for the harshest conditions, they allow athletes to stay focused on their goals by providing optimal visibility regardless of circumstances.

What unique performance do REACTIV lenses offer?

REACTIV lens technology includes unique features that distinguish them from standard lenses. Their durability is exceptional: resistant to scratches and impacts, even in tough environments like high mountains, deserts, or the sea. These conditions require flawless vision to navigate safely. That’s where REACTIV lenses fully demonstrate their capabilities.

Unlike traditional photochromic coatings, REACTIV technology is integrated directly into the lens material. This innovation ensures unmatched longevity: the lenses maintain their photochromic properties over time, even with intensive use. Even with scratches or natural wear, the responsiveness remains intact, providing consistent visual performance during your most ambitious adventures.

How to care for your REACTIV lenses to extend their effectiveness?

To maintain REACTIV lens performance over time, a few simple habits will help. It’s recommended to clean them with gentle products and avoid excessive rubbing that could impair clarity. Use lukewarm water and a microfiber cloth for delicate, effective cleaning.

Proper storage is also key: protective cases help preserve the lenses’ photochromic properties long-term. Always store them in a rigid case when not in use to avoid shocks and scratches. By caring for your REACTIV lenses, you ensure lasting quality vision and perfect adaptability—ready to meet every challenge.
