That precision allows us to offer prescription lenses in both REACTIV photochromic and SPECTRON options, so you never have to choose between performance technology and prescription accuracy. Whether adapting to changing light or protecting in bright conditions, your vision is engineered with the same innovation trusted by athletes worldwide.

REACTIV PHOTOCHROMIC LENS FEATURES

WIDEST RANGE, FASTEST TRANSITION

Julbo REACTIV lenses set the standard with the widest photochromic range, fastest transition time, and most styles on the market.

ONE LENS, FOR ANY CONDITION

Built for performance, REACTIV lenses are anti-fog, non-temperature-sensitive, and backed by the REACTIV Lifetime Warranty.

UNMATCHED OPTICAL CLARITY

Each REACTIV lens is crafted from Trivex with our photochromic formula injected directly into the lens itself. No coatings, no expiration — just uncompromised performance.

LIGHTWEIGHT, ALL-DAY COMFORT

Purpose-built to be lightweight yet durable, REACTIV lenses are engineered for all-day performance — trusted by outdoor athletes since 1888.

How REACTIV Photochromic Technology Works in Rx Lenses

REACTIV photochromic technology adapts faster and across a wider light range than any other prescription lens on the market — giving you corrected, crystal-clear vision from whiteouts to bluebird skies without reaching for a second pair. Rx REACTIV lenses deliver the optical precision prescription wearers demand with the lightweight strength built for high-performance use.
Because the adaptive technology is embedded directly into the lens, it works in harmony with your prescription — never degrading, never peeling, never compromising your corrective optics. Each Rx lens takes nearly 20 hours to craft, is precision-ground to your exact prescription, and is backed by a lifetime warranty. One pair, built to last, performing at its best every season.

Why Use a REACTIV Lens?

REACTIV lenses take the guesswork out of any adventure, adapting instantly to shifting light whether you’re running through the trees, biking under clouds, or skiing in and out of the glades.

Mountain weather changes quickly — photochromic is perfect if you ski, bike, or hike through shifting light, clouds, and storms in the same day.

One lens works from dawn patrol to sunset laps, so you don’t have to carry extras.

Great for activities where you’re moving between sun and shade (tree runs, ridge lines, forest trails).

If you want one pair of goggles or sunglasses that does everything, photochromic is the most versatile solution.

Lenses react in seconds to shifting light, so your eyes never need to adjust — critical for high-speed descents or fast-changing terrain.

Which REACTIV Rx Lens is Right For You?

Julbo has several unique REACTIV Rx lenses available in prescription. Click through to find your ideal pair.

Rx REACTIV 0-3 lenses

Purpose: The widest light-adapting range available in a prescription lens — built for athletes who can't afford to swap eyewear mid-mission. Your Rx stays with you from pre-dawn darkness through blinding alpine summits, so you're never choosing between clear vision and the right tint.

Best For: Backcountry skiing, ski mountaineering, high-alpine climbing, long-distance cycling, and multi-day expeditions where light swings are dramatic and stopping to change glasses isn't an option.

Rx REACTIV 1-3 LENSES

Purpose: The most versatile prescription photochromic option in the lineup — and the fastest to react when light shifts from low to bright. For Rx wearers who want one pair that handles everything, this is it. Available in the widest range of colors so you don't have to compromise on style or optics.

Best For: All-day resort skiing, trail running, mountain biking, road cycling, and everyday outdoor use where conditions change throughout the day and your prescription needs to keep up.

Rx REACTIV 2-4 LENSES

Purpose: For prescription wearers who spend most of their time in high-glare, high-altitude environments, this lens delivers maximum darkening speed and optical precision right when you need it most. You get full corrective clarity without sacrificing eye protection where the sun hits hardest.

Best For: Glacier travel, mountaineering, spring skiing, desert expeditions, and water-based adventures — anywhere reflective surfaces and intense UV make standard Rx sunwear fall short.

Rx POLARIZED

Purpose: Polarized Rx lenses eliminate the reflected glare that makes visual detail hard to read — off snow, water, rock, and pavement. For prescription wearers, polarization isn't just comfort, it's sharper, more accurate vision in the exact conditions where your eyes work hardest.

Pair With REACTIV Rx: Add photochromic adaptation to your polarized prescription and you have a lens that actively manages both glare and changing light — no compromises, no lens swaps.

Best For: Water sports, alpine skiing, glacier travel, road cycling, paddling, and any bright day where glare compounds the challenge of seeing clearly with corrected vision.

Rx HIGH CONTRAST

Purpose: High Contrast Rx lenses sharpen the difference between light and shadow, making terrain, texture, and obstacles easier to read — even in flat or mixed light. For prescription wearers navigating technical terrain, this is the difference between reacting in time and getting caught off guard.

Pair With REACTIV Rx: Combine High Contrast with photochromic Rx for precision vision through every light transition — your prescription adapts with you from shaded forest to open ridgeline.

Best For: Mountain biking, trail running, variable-light skiing, technical alpine routes, and any environment where shadow and light shift constantly and your eyes need every advantage.

Rx LIGHT AMPLIFIER

Purpose: Light Amplifier Rx lenses brighten your corrected view in low-light, overcast, and stormy conditions — keeping detail sharp when your surroundings go flat. For Rx wearers, this means your prescription is optimized for the moments when reduced light makes seeing clearly most critical.

Pair With REACTIV Rx: Paired with photochromic Rx technology, Light Amplifier ensures you're seeing clearly from the first step of a pre-dawn start to the final descent at dusk — all through a single, corrected lens.

Best For: Early-morning starts, storm skiing, dusk missions, night trail runs, and any low-light alpine push where your prescription needs to perform as hard as you do.

Julbo RX FAQ

Get answers about Julbo’s custom RX lens process, advanced lens technologies, and how we deliver performance without compromise.

Can I cancel or edit my prescription order after placing it?

No. Once a prescription order has been submitted, it enters our production queue and cannot be edited, modified, or canceled. We strongly recommend carefully reviewing your prescription values, frame selection, and lens choice before submitting your order.

How long does JulboRx processing take?

Once your prescription order is submitted, the typical turnaround time is about 5–8 weeks. This timeframe includes production at the lab in France, international shipping to the U.S., and final quality inspection before shipment. After the order reaches the U.S. warehouse, it is shipped to you via FedEx with 3-day delivery. You’ll receive tracking information once your order ships from our warehouse.

Can prescription orders be expedited?

Prescription orders from the Julbo RX Lab cannot be expedited beyond the standard process. Because these are custom-made lenses produced in France, the timeline is driven by lab fabrication and international shipping; the only expedited portion is the included 3-day FedEx delivery after the product arrives in the U.S. warehouse.

I own a pair of Julbos. Can I purchase a set of Julbo RX Lab Prescription lenses for them?

All Julbo Rx lenses must be fitted into a new frame at our Lab in Jura, France and thus, we do not sell spare prescription lenses to put into a preexisting pair of Julbos. A big part of the process is ensuring a precise fit of the lens into the frame. However, there is no cost associated with the new frame!

Can I try on JulboRx frames before placing my order?

We understand that trying on frames before purchasing can be important, and we apologize for any inconvenience this change may cause. We recommend visiting a local dealer using our store locator here: https://julbo.us/pages/store-locator. If you have a nearby REI, they typically carry the widest selection of frames to try on in person.

If visiting a dealer isn’t an option, you are welcome to place an order directly through our website and process our return. You can find our non-Rx return policy linked here


Additionally, you can email our customer service team at info@julbousa.com to  let us know what activities you participate in, along with any frames or lenses you’re considering, our customer service team would be happy to help narrow down the best options for your needs.
