Julbo Lens Color
Description |
All Julbo lenses belong to optical class 1 and guarantee 100% protection
against UVA, B and C.
Special treatments: Julbo is an expert in solar protection for
high -risk environments and develops highly specific treatments for each
condition of use.
- Anti-fog: Applied by laser on the inside of the lens to guarantee
maximum life. This same technology is used on helmet visors for grand prix
racing.
- Anti-Reflection: Increase optical comfort and eliminates parasitic
reflections.
- Brown Out: Gives enhanced filtration of visible light.
- Flash: Increases visible light filtering through a mirror effect
on the lens.
- Hydrophobic: Causes water to slip off the lens. The treatment
prevents the creation of hydrogen links between water molecules. Visibility
is enhanced.

Lens Materials:
- ARC Mineral: Recommended for deserts and mountaineering. Glass.
Excellent quality optics, scratch resistance, extra infrared protection.
Additional treatment to provide more impact resistance.
- Spectron Polycarbonate: Recommended for all sports. Shock
resistant and lightweight. Anti-scratch surface treatment.
- NXT: High definition vision, superior optical quality, optimum
transparency; light and unbreakable; lasting strength and resistance to
solvents. Made using low-temperature casting techniques which reduce
internal stress in the material, this improves optical quality, gives
excellent transparency, and increases long-term stability. NXT lenses were
developed for the US Army. 3 high technology NXT lenses:
- Polar + : High precision polarizing lens with
anti-reflection. This lens optimizes the view, cutting out distortion, and
eliminating dazzling sun glints from all reflective surfaces.
- Zebra: Photochromic lens. Wide amplitude in categories 2
to 4 with fast activation speed (22 to 28 seconds). Anti-fog treatment. The
glass darkens or lightens as the surrounding brightness changes (from 40.7%
to 6.6% of the visible light transmission rate depending on luminous
intensity). Recommended for mountain biking, trails and climbing.
- Cameleon: Photochromic and polarizing, dual
technologies. Progressive protection in categories 3 to 4. Anti-glare,
high definition polarizing lens which darkens or lightens as the brightness
changes. Recommended for water sports and mountaineering.
