Lens Information

Blue Light

Mountains in Tignes in various light.

The snow reflects the sky which is blue. This means that the eye is overwhelmed by blue light and it is difficult to read the shades of the snow. The same applies when looking at the sky.

However, some blue light is needed by the eye to “read” the snow. It is therefore necessary to have the right amount of blue light into the eye.

The correct lenses for this environment partially reduces a portion of blue light and enables you to read the different shades of the snow. Instead of seeing the snow as a flat blue surface, you will be able to see moguls and hollows.

Lens colors and mirrors

We offer two base lenses/filers: orange and grey. These base lenses/filters are combined with different mirrors to create unique solutions for seeing more and protecting your eyes in various conditions.

Orange lenses are more focused on creating contrast in cloudy, low light to partially cloudy conditions and the grey base lenses are more about reducing light in bright and sunny conditions.

ENHANCED CONTRASTS: the peak of yellow/green in the spectral curve allows to see contrasts, gradation and shade of the slope.
SNOW DETECTOR: good vision of contrasts together combined with the partial reduction of blue light lets read the different shades of the snow.

NEUTRAL AND NATURAL: natural perception of colors thanks to the flat shape of the spectral curve.
BLUE LIGHT REDUCTION: The blue light is gradually reduced
COMFORT: the result is a comfortable vision without overload to the eye. Ideal for extended use.

Mirrors and Coatings
The color on the mirror is for creating a certain effect in combination with the lens/filter color. It’s all about performance, not looks!
