Bicycle glasses with photochromic lenses | Kalsten

The wind is in your face, but the sun is shining so brightly that you can hardly see the curve.

On the MTB trail or long road descents, light and shadow are constantly changing. Glasses with a fixed tint can leave you blind in the tunnel, while clear lenses are painful in the bright sun. The photochromic cycling glasses automatically adapt to every light situation – from dark forest paths to dazzling midday sun – so you can focus on the line and not on your vision. The TR-90 frame weighs a barely noticeable 30 g on your nose.

Benefits

• No more lens swapping on the go: The lenses handle the darkening themselves – you never stop, rummage in your backpack, or waste time changing glasses between tunnels and open stretches.
• No more straining your eyes: No glare in the sun or blurry vision in the shade – you ride comfortably for hours because the lens constantly provides optimal contrast.
• No worries about UV damage on long tours: The UV400 protection completely blocks UVA and UVB rays, so you don’t have to worry about burning eyes after a long summer day in the saddle.

Application

1. Wearing: Position the glasses comfortably on your nose – the temples rest flat against your temples.
2. Riding: The lens automatically adapts to the current lighting situation; no manual intervention is needed.
3. Cleaning: After the ride, dust and sweat can be easily wiped away with the included eyeglass cloth without damaging the photochromic coating.

Pro tip: Do not store the glasses in direct sunlight – prolonged UV exposure when not riding shortens the reaction time of the photochromic lens. Keeping them in the included case or an inner pocket keeps the lens responsive for longer.
