react wins ISPO Award 2022 for optray sports sunglasses

Fast lens tinting for sports sunglasses takes on a new dimension with the react optray. Well-made, useful intelligent technology, perfect fit. Handmade in Switzerland.


Lightning fast!

Thanks to our ShadeTronic® technology, our lenses detect changes in ambient light and adapt accordingly in less than a tenth of a second. You won’t even notice – you have other things on your mind.


Our lenses darken 300 times faster than conventional photochromic lenses and lighten 1200 times faster, so you never lose focus.


Because our lenses shift automatically between medium, dark and very dark tints, you never need to change your sunglasses or lenses while on the move.


Our polarized, UV400-rated lenses protect your eyes from dangerous UV rays, so you can see clearly and safely at all times.


Solar-powered adventure

Integrated solar cells power the liquid crystals in our lens, causing them to lighten and darken in response to changing light conditions in just a tenth of a second. No charging is necessary because there is no battery.

Optimal visibility with react

As every athlete knows from experience, lighting conditions can change rapidly during a training session or a race. And for everyone trying to adapt to the light conditions, react becomes a real advantage.

The glasses for every moment

As a balloonist, I am fully exposed to the sun; down in the basket, where my noteboard lies and I have to take notes, it is considerably darker. These light changes are challenges that only a few glasses can master.

Dimming in lightning speed

I can confirm the automatic dimming of 0.1 seconds of the react glasses! It is not just an empty promise. I find it particularly cool that the glasses also change back to bright in the same reaction time.

If you try them, you want them!

Many customers take our react test glasses for a spin around the block. The react is particularly convincing in fast light changes. Once you have tried a react, you usually want to buy one.

Your perfect companion!

A perfect fit on the face with optimum protection against the wind, making cycling an experience, even for people who wear contact lenses. The adjustment to the light conditions gives you a clear view at all times and creates confidence even in unknown terrain.
