WHICH LENS FOR WHICH SPORT?
WHY?
For each environment, a wavelength of light is dominant and can interfere with the perception of CONTRAST and RELIEFS.
In order to have the best possible protection and comfort of vision in its environment of practice, there is an adapted tint of glass allowing to compensate the naturally dominant color. The chromatic circle of colors allows to find the correspondence between the color of tinted glass and the dominant color of the environment.




THE BEST PROTECTION AGAINST CHANGING LIGHT

RAFALE photochromic lenses adapt automatically to ambient light, adjusting to suit UV intensity. They darken outdoors, and lighten indoors, whatever the temperature. They allow athletes to enjoy the best light regardless of the weather, without the need to switch frames, meaning they offer constant visual comfort!
The RAFALE range covers all outdoor sports for all environments.

CLARITY OF VISION

BORA technology brings the precision that is essential for the performance and visual comfort that every athlete seeks.
STRENGTH AND PROTECTION
Polycarbonate lenses have ten times the impact resistance of standard lenses, and they offer 100% UV protection.
DURABILITY
The photochromic treatment is designed to stand the test of time. The special production technique prevents deterioration. Poured at a low temperature, the lens has the photochromic treatment incorporated into it.
IMPROVED CONTRAST
RAFALE and BORA lenses improve vision by accentuating relief. They are a real asset in sports such as snowsports, fishing or golf, where the athlete requires perfect vision of their environment to hone their skills.

COATINGS
HYDROPHOBIC/OIL-REPELLENT
Weather conditions or perspiration can also hamper the wearer’s visual perception. A hydrophobic coating prevents droplets building up on the lens surface, allowing the wearer to concentrate fully on their performance.
ANTI-FOG
This lens coating ensures that temperature differences and perspiration won’t fog the lenses, for optimal visual comfort during physical exertion.
ANTI-REFLECTION
The purpose of this surface treatment is to considerably reduce unwanted reflections. It increases the quantity of light passing through the lens, and so provides clearer vision.
POLARIZED
Polarized lenses provide 100% protection from UV rays and glare, and reduce eye fatigue. By limiting the sun’s reflections on reflective surfaces (water, snow, windshield, asphalt…), they considerably improve the wearer’s comfort and visual perception.

VISION WITH NO MORE LIMITS!


SPORT GLASSES TO SUIT YOUR VISION
At French laboratory, Demetz produces sport equipment that is 100% adapted to the wearer’s vision (adults and children): diving masks, swimming goggles, curved frames, special glasses for ball/racquet sports.
