Which sunglasses for which sport?

WATERSPORTS: SAILING, KITESURFING, STAND UP PADDLE (SUP)

We recommend a flexible and wraparound frame to prevent water splashes, but with good ventilation to prevent fogging: suspended or perforated lenses. There are also floating sunglasses, an interesting feature for all watersports where you can easily reach out to retrieve your glasses if needed.

SUNGLASS LENSES

HIGH MOUNTAINS: SKIING, HIKING, TREKKING, MOUNTAINEERING

The higher the altitude, the more harmful the sun's rays become, so it's crucial to have good sun protection in high mountains. We offer the widest range of lenses dedicated to mountain and high-mountain activities. Within our range of lenses, we offer REACTIV photochromic lenses that adapt to the brightness throughout the day, SPECTRON polycarbonate lenses (fixed tint), and Alti Arc mineral lenses (fixed tint). In high mountains, it's not just about being protected from the sun, but also from wind, cold, and snow with rapidly changing weather. The advantage of a photochromic lens, which darkens or lightens depending on the ambient light, is to provide optimal eye protection regardless of sunlight conditions. We recommend, for high mountains, the REACTIV lenses:

• REACTIV 2-4 Polarized: photochromic and polarizing lens from category 2 to 4 (visible light transmission rate 20-5%). In addition to darkening and lightening according to ambient light, it eliminates reflections on reflective surfaces. Its brown color provides excellent perception of the snow surface and improves contrasts.
• REACTIV 2-4: photochromic lens from category 2 to 4 (35-7%). Its brown-yellow vision color increases brightness and provides excellent depth perception. It is lighter, brighter, and activates faster than the REACTIV 2-4 Polarized.

ENDURANCE SPORTS: CYCLING, MOUNTAIN BIKING, TRAIL RUNNING, CROSS-COUNTRY SKIING, TRIATHLON

These sports are practiced on varied terrains, from plains to undergrowth, so we highly recommend a photochromic lens that adapts to these changes in light conditions, without the need to change or remove your glasses. At Julbo, different protection ranges exist, so it's up to you to choose according to your usage:

• Sunny or nighttime: REACTIV 0-3 (visible light transmission rate 12 to 87%)
• Sunny to overcast or from dawn to dusk: REACTIV 1-3 High Contrast category 1 to 3 (13 to 72%), well adapted for winter conditions, or REACTIV 1-3 Light Amplifier category 1 to 3 (17 to 75%)
• Strong sunlight to cloudy weather: REACTIV 2-4 category 2 to 4 (7 to 35%)

You can also opt for a category 3 polycarbonate lens, highly versatile in its usage (SPECTRON 3).

WATERSPORTS: SAILING, KITESURFING, STAND UP PADDLE (SUP)

At the water's edge or on the water, we strongly recommend choosing polarized lenses. They eliminate sun glare on reflective surfaces, providing a clear vision of the horizon without any annoying reflections and allowing you to distinguish gusts. The polarizing treatment may affect reading on screens.

Once again, photochromic lenses offer undeniable visual comfort regardless of the weather: from strong sunlight to cloudy conditions. Therefore, we recommend the REACTIV 2-3 Polarized lens (32 to 9%), which is also polarized and specially developed for all watersports.

For reasons of budget or versatility, our Spectron 3 Polarized lenses in polycarbonate are also a very good option.
