Julbo REACTIV Photochromic lens technology


Unrivaled Optical Quality, No Matter The Light Conditions

Julbo has seven unique REACTIV lenses available. These REACTIV lenses offer the widest photochromic range and the fastest reaction time on the market.

Each lens takes nearly 20 hours to make and is casted from Trivex, a material used in helicopter windshields. That means the optical quality is nearly as good as glass and far superior to the polycarbonate lenses that most other brands use. It’s also why our REACTIV photochromic technology never wears off, meaning we can back our lenses with a lifetime warranty. 


Photochromic lenses automatically lighten or darken depending on the amount of UV light. The more UV light present, the darker the lenses will become, protecting your eyes from harmful UV rays and providing crystal-clear visibility no matter the light conditions. 



Julbo REACTIV lenses are equipped with the most advanced photochromic technology, which makes them ideal for any activity.

Julbo REACTIV Photochromic lenses offer the wides photochromic ranges

Julbo makes a lens for every possible condition, with our REACTIV lenses offering the widest photochromic range on the market. Our clear to dark lenses range from 87-12% Visible Light Transmission (VLT) while our Performance lenses range from 35-7% VLT. 

Julbo REACTIV lenses have the fastest response to changes in light

It takes about 20 seconds for Julbo's REACTIV lenses to change from their lightest to darkest tints, making them the fastest to react on the market.

Julbo REACTIV lenses are non-temperature sensitive

The photochromic technology is built into Julbo's REACTIV lenses, ensuring they are unaffected by changes in temperature and will only adjust to available light.

Julbo REACTIV lenses are treated with an anti-fog coating

Each REACTIV lens is treated with a long-lasting, scratch-resistant anti-fog coating. With proper care and washing, this coating will last for the lifetime of the lens.


Julbo REACTIV lenses come in a variety of colors, and each lens provides a different range of Visible Light Transmission. That means there is a perfect lens for any condition.
