Category 3 solar lenses provide a perfect filter for most light conditions. Your solar lenses will filter 83 to 92% of sunlight. They offer excellent eye protection from sun rays and glare for most of your activities. This protection is particularly effective in conditions of strong sunlight (during summer, holidays by the sea, on the beach and winter sports).


Category 2 solar lenses will filter out 58% to 82% of ambient sunlight. This protection is effective in medium sunlight conditions. Category 2 lenses can be worn in periods of variable sunlight and between seasons, for example at the beginning of spring and the end of autumn.




Polarised lenses:

  • you're not dazzled by the sun
  • your vision is clearer
  • more realistic colour and contrast perception
  • 100% UV protection for your eyes and eyesight

No more sun dazzle.


More than a simple coating, photochromic technology is embedded within the molecular structure of the lens. Therefore, your lenses will lighten and darken instantly depending of the light conditions, protecting your eyes from harmful UV rays.




Thermogrip®: Hydrophobic nose pads and comfortable branch tips hold your sunglasses in place and allow you to focus on what you're doing.
