Why choose photochromic lenses for your sunglasses?

If you do sports outdoors, then quality, safety and comfort are the top priorities when choosing your equipment. And where does facial protection come into all that? If you are looking for excellence, we highly recommend opting for photochromic lenses. Here is why.

Why choose photochromic lenses for your sunglasses?

What is a photochromic lens?

A transitioning, adaptive, variable, changing lens. There are all sorts of adjectives to describe how a "photochromic" lens works but its benefits remain the same. A photochromic lens is a lens that becomes darker or lighter depending on how much light there is, while protecting the eyes from UV light.



The answer for all outdoor sports

Whether you are on the sea or in the mountains, the weather can change very quickly. A cloudy day can quickly give way to bright sunshine. And when you are running, walking, skiing or riding, you will often move from a sunny patch (flat, open land) to a shady area (woodland).


So what can you do in these situations? Not bother wearing sunglasses and risk UV light damaging your eyes? Keep your glasses on with the wrong lenses for the situation and risk taking a tumble due to poor vision? Always keep two or three different pairs of glasses on you and change them as needed?



To avoid all this, you simply need a pair of photochromic lenses so that you always have great vision despite changes in the level of light: just one pair of sunglasses can deal with any amount of sunshine, whatever the weather and wherever you are!



Technology for enhanced performance

At Julbo, our photochromic lenses are manufactured using a mass casting method that produces high-quality, flawless lenses.

Which photochromic lenses should you choose?

Depending on the activity you are doing, we offer five lenses that can respond to different situations:



We recommend the Zebra (cat. 2 to 4) and Zebra Light (cat. 1 to 3) photochromic lenses for climbing and endurance sports such as mountain biking, trail running and Nordic skiing.


In areas that are very bright or if you have delicate eyes, we would recommend the Zebra lens. Its light version, the Zebra Light, is more designed for athletes exercising early in the morning or at the end of the day when the sun is low in the sky, as well as for people living in areas with less light.

For people who regularly head to the top of the mountains or the desert, do water sports, or for everyday use, we recommend opting for lenses that are both photochromic and polarising.


The Cameleon lens (cat. 2 to 4) has a high photochromic index (visible light transmission:  5-20%) for high in the mountains or in the desert.

The Octopus lens (cat. 2 to 4), which is grey in order to faithfully reproduce contrasts, is perfect for looking across the water when doing any water sport.
