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.

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.

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.

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.

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.
