FAQ

Photochromic lenses adjust to changing light conditions by getting lighter or darker depending on the amount of UV light present. The more UV light—or the brighter the conditions—the darker the lens becomes, and vice versa. REACTIV is the name for our proprietary photochromic technology. 

 REACTIV photochromic technology is helpful when the weather changes, if you're recreating early or late in the day or if you're in and out of the woods frequently. Since the lenses change how light and dark they are, you don't need to switch from one lens to another or take off your sunglasses/goggles as conditions change.

Julbo offers a variety of REACTIV photochromic lenses, which are available in polarized and non-polarized options.

REACTIV lenses are photochromic and adjust to changing light conditions by getting lighter or darker depending on the amount of UV light present. REACTIV lenses are made of NXT (Trivex), which has the clarity of glass and exceptional durability and impact resistance. 

SPECTRON lenses are not photochromic and will not lighten or darken. SPECTRON lenses are made of polycarbonate, which is shatter resistant, and are a versatile lens suitable for all types of activities.

Visible Light Transmission (VLT) refers to the percentage of light that filters through a lens—the higher the number, the more light passes through. A window in a home, for example, might have a VLT of around 70%, allowing most visible light to pass through while filtering enough to keep your sofa from getting bleached. A typical goggle lens, like a home’s window, has a fixed VLT—the amount of light it lets through and blocks out remains the same, no matter how bright or dark it is outside. 

The VLT of Julbo’s REACTIV lenses, on the other hand, changes as ambient light changes. The new REACTIV 0-4 lens, which has the widest VLT range of any photochromic lens on the market, has a range of 83 to 5%. In other words, just 5% of visible light filters through the lens under extremely bright conditions, allowing for ultimate protection. Conversely, 83% of visible light filters through when it's dark out, allowing for total clarity. Regardless of VLT, REACTIV lenses filter 100% of harmful UVA, B, and C light.

High Contrast lenses have a rose tint and rose base color, designed to enhance contrast. HC (rose/red) tints are ideal for situations with varied terrain in low light, for example snowy, flat light or during poor weather. 

Light Amplifier lenses have a yellow tint and yellow base color, designed to brighten everything by increasing light receptivity. LAF (yellow) tints are ideal for darker conditions, like trail running and mountain biking in the woods or recreating early and late in the day.

    Peak bagging already

    Obviously great style points when you wear these! Took these up Rainer this past weekend. They gave me the comfort of knowing my nose was protected at all times. The only reason I gave it a 4/5 instead of 5/5 is that the side shields and nose piece come off easier than I would like them too; had a side piece pop off when I was adjusting helmet and hood but luckily my friend noticed so I could put it back on.

    Disappointing

    The glasses are very cool but don’t get dark enough even in very bright light

    Hi Daniel,

    Thank you for sharing your feedback. We're sorry to hear that the lens on your Ultimate Cover didn’t meet your expectations. If you're looking for a darker option, we recommend the REACTIV 2-4 lens, which features a brown tint and is designed specifically for high-altitude, bright-light conditions.

    We’d love to help you find the ideal lens for your needs. Please feel free to reach out to our customer service team at info@julbousa.com, and we’ll be happy to assist you in finding the best solution.

    We truly appreciate your support and your input—it helps us continue to improve.

    Best regards,
    Julbo USA Customer Service Team

    Very Nice Glasses

    Really like the cat 2-4 lenses and the fit of the glasses.

    Only disappointment is the case that comes with the glasses. Very tight fit and soft side. With these high-end glasses, I’d expect a hard case for adequate protection on long treks.
