Purpose: These are Julbo’s most adaptive lenses, designed to perform from total darkness to full sun. With the widest VLT range on the market, they transition seamlessly from night missions and pre-dawn starts to bright alpine summits — eliminating the need for multiple lenses.

Best For: Backcountry skiing, ski mountaineering, high-alpine climbing, long-distance cycling, ultra trail running, and multi-day expeditions where light conditions change drastically.

Purpose: The most versatile all-around lens, REACTIV 1–3 has the quickest transition to shifting light from low to bright on the market, making it ideal for full-day missions without swapping eyewear. It balances reactivity, clarity, and comfort across a wide range of conditions. It also comes in our widest selection of colors.

Best For: All-day resort skiing, trail running, mountain biking, road cycling, and everyday outdoor use where conditions vary but don’t reach extreme ends of the spectrum.

Purpose: Engineered for high-altitude, high-glare environments, REACTIV 2–4 delivers peak performance in intense sunlight. It darkens rapidly to protect your eyes while maintaining optical precision — perfect for those who spend most of their time above treeline or on reflective surfaces.

Best For: Glacier travel, mountaineering, high-altitude alpine missions, spring skiing, desert expeditions, and water-based adventures.

Purpose: Polarized lenses eliminate harsh glare reflected off snow, water, rock, and pavement — giving you sharper vision, enhanced contrast, and reduced eye strain. By filtering out horizontal light waves, they cut visual “noise” so you can focus on what’s ahead.

Pair With REACTIV: Combine polarized tech with REACTIV photochromic for unmatched clarity and comfort as light and conditions change.

Best For: Water sports, alpine skiing, glacier travel, road cycling, paddling, mountaineering, and bright days on snow or water where glare is at its worst.

Purpose: Glare Control lenses fine-tune how light reaches your eyes, reducing brightness without overly darkening your view. This ensures crisp detail and visual comfort even under intense sunlight, extended exposure, or highly reflective terrain.

Pair With REACTIV: Glare Control adds another layer of precision to photochromic adaptation — maintaining consistent comfort across shifting light conditions.

Best For: High-altitude skiing and mountaineering, desert or alpine environments, glacier travel, and long summer missions where light intensity stays consistently high.

Purpose: High Contrast lenses boost depth perception and definition by enhancing differences between light and shadow. This makes textures, terrain, and obstacles easier to read, even in mixed or flat light — so you react faster and move with more confidence.

Pair With REACTIV: Combining High Contrast with photochromic tech gives you the sharpest possible vision through every light transition — from dark forest to bright ridgeline.

Best For: Mountain biking, trail running, forested or variable-light skiing, technical alpine routes, and any environment where shadows and light are constantly changing.

Purpose: Light Amplifier lenses are designed to maximize available light, brightening your surroundings and improving clarity in low-light, cloudy, or stormy conditions. They enhance visibility without adding glare, keeping detail sharp when light is limited.

Pair With REACTIV: Pairing Light Amplifier with photochromic tech ensures seamless visibility from first light to nightfall — perfect for long missions that start or end in the dark.

Best For: Early-morning starts, dusk missions, storm skiing, night trail runs, and low-light alpine pushes.
