REACTIV photochromic sunglass lenses. The world's most advanced lenses

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. 

Proper cleaning helps prevent damage and extends the life of your lenses. Avoid using solvents, chemical cleaners, paper products, gloves, or anything abrasive, as these can scratch the lens. Scratches are not covered under our lifetime warranty, so be sure to clean and store your eyewear carefully to keep it in top shape.

CLEANING SUNGLASSES

1. Gently wash the frame and lens in soapy water.

2. Rinse the frame and lens thoroughly with clean water.

3. Wipe away moisture with a soft microfiber cloth or non-abrasive material. Let the glasses air-dry.

4. Store glasses in their microfiber case/pouch. Avoid direct sunlight or leaving next to a heat source.

    Lens quality is unbelievable

    These sunglasses are by far the best lens I have ever tried and their fit is fantastic if for smaller faces. I really struggle to find sunglasses that fit and these really work well. The nose pieces and temples are cushioned making them very comfortable. Best sunglasses I have purchased!

    So happy with these

    I always hesitate to order sunglasses without being able to try them, but these were such a good choice. Everything is so crisp and clear. They are fabulous for biking and for just walking around. Love them. And on another note, I ordered two pairs and one did not fit my face right, and the company made it so easy to return them

    The BEST lenses

    The Spark are my absolute favorite sunglasses from Julbo. First off, they are classy and stylish enough to walk around downtown after climbing. Second, the Reactiv photocromatic lens really work as does the glare control — they are fantastic for driving. I also wear my Sparks climbing and hiking. The nose grip is so comfortable I don’t notice them on and they fit under my climbing helmet! They just look and feel so good that they make me happy — you’ll love these. Julbo make the highest quality lenses around — I can’t recommend these more highly. ⭐️⭐️⭐️⭐️⭐️
