REACTIV Photochromic lenses automatically adjust to UV light conditions. REACTIV technology enhances contrast and amplifies clarity, reducing eye fatigue during your adventures. Julbo lenses are shatterproof and scratch-resistant, and all our eyewear is backed with a lifetime guarantee.
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. Julbo calls its photochromic technology REACTIV. 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.
- OOliverVerified BuyerRated 4 out of 5 stars1 month agoFantastic sunglasses but fit wasn't right for me
Ultimately, I returned these sunglasses because the fit is a little bit too high on my face. I really wish they had a "low bridge" version, or similar. I found that they were sitting above my eyebrows and had limited coverage when looking down at my feet. I would really prefer if they sat lower on my face without being further down my nose, if that makes sense. (fit pic attached)
Extremely light. It almost doesn't feel like you're wearing anything. The lenses are excellent, I liked them a lot more than my polarized Oakley Radar lenses and they certainly enhance visibility when running on the trails. However, they are a bit sticky making them hard to clean.
Overall, awesome sunglasses, but for me purchasing them at this price, the fit has to be perfect.
- RRubyRated 5 out of 5 stars3 months agoLightweight and Flashy
An incredible pair of glasses, for training and for racing. So lightweight, these glasses sit securely during movement and don’t slide around. The reactive lenses crush it, adapting to various environments and conditions. So impressed!
- JLJamie L.Rated 5 out of 5 stars4 months agoDensity photochromatic
I have been using the Density for road and MTB cycling daily and enjoy the lightness and stable fit. I have been comparing them to my Ultimates that have an iridial reflective coating and I think I may have slightly more glare with the Density when riding into the sun in the early morning, The comfort and coverage of the Density is excellent and I have had no fogging with hard 4 hour rides. Highly recommend and perhaps a more reflective lens would make them almost perfect or a 0-4 lens. Thanks Julbo for continually looking for better and more functional designs. I do think the optics are better on this Density from my previous Ultimates
- JPjoshuah p.Rated 5 out of 5 stars4 months agoGreat fit, barely there, perfect lenses.
The size and fit of these is fantastic!
the moldable arms are a great touch to dial in the fit, also they are so insanely light that they are nearly imperceptible.
the lenses do not fog even on sweaty climbs, and shift beautifully through different lighting.
my only gripe is that when clear they look as if i were about to administer open heart surgery, which i am not qualified to do.
Julbo Eyewear4 months agoHey Joshua, thanks for your review of the Density sunglasses. Love to hear that the light frame and internal anti fog coating are performing well for you! Cheers, Molly
- RMRenato M.Rated 4 out of 5 stars4 months agoGood not great!
These are a good pair of glasses for cycling but not great. The reactive doesn't works that great I took lens with 0-3 cat, and it is very good with low light (5am -7am) but on bright and direct sun light the lens don't get dark enough. Another thing that drives me crazy is that it is hard to clean its lens, they are very sticky and hard to swap a tissue to clean. Overall it is beautiful and well done, large as a big head need :-)
