Manufacturers promise better vision on the trail thanks to contrast-enhancing sports glasses. The test shows which of these 18 models between 75 and 230 euros will give you the best vision.

The blow comes completely unexpectedly. The branch hits the biker in the face like a whiplash. It could have hit him in the eye. Only the sunglasses can act as a protective shield to prevent worse. Have you ever experienced this? Sports glasses are often both the guardian angel and the culprit. Sometimes too dark for the wooded trail, sometimes too lacking in contrast for a sunny day. As a biker, you often barely have a chance of recognising a low-hanging branch when riding fast against the light. So the lenses made of shatterproof polycarbonate have to do the job.

The fact that bikers see less well in bright sunshine is due to the high proportion of blue in sunlight. The light of these wavelengths overlays the other colours and shrouds the surroundings in a hazy haze. A big problem for bikers. Bikers need glasses that primarily emphasise brown, red and green tones and keep the short-wave blue light away from the eye.

LST Active, ChromaPop, Prizm or Clarity - manufacturers use these terms to advertise on their websites. These are not new designer drugs, but contrast-enhancing technologies. However, only the spectrometer can prove how good the new contrast enhancers really are.
