These lenses adjust their tint in just 0.1 seconds… faster than your eye can blink.
REACT glasses use Swiss-made ShadeTronic technology, originally developed for professional welding masks, to automatically adapt to changing light conditions. No batteries, fully solar powered, and with full UV400 protection.
For anyone golfing, cycling or running in unpredictable British light, this really is a game changer. Clearer vision, better contrast, and no need to switch between lenses.
We’ve got demo pairs in the studio if you’d like to try them for yourself.
