NACAN II P, Sports glasses

All Alpina lenses provide 100% UV-A-, -B-, -C-protection and thus guarantee excellent eye protection.

Mirror is a lens on which multiple reflective layers are applied. They provide protection from harsh glares and infrared light. Mirror is not only the feature of a highly functional lens, it’s an element of style.

Glasses with polarised technology have polarising lenses. This means they filter light and only let direct rays of sun through. As a result, distracting reflections and glares are blocked and do not reach the eyes. This makes these glasses an outstanding choice for types of sport in and on the water.

Quattroflex is the term for a specially coloured lens in ruby red, which reduces the proportion of blue in visible light. This increases contrasts in the snow, allowing surroundings to be perceived better and more quickly. Thanks to the lens’s brightening effect, the contours and textures of the piste can be perceived better even in poor weather conditions. A polarisation film of highest optical quality built into the lens completes the Quattroflex effect: Distracting scattered light and glares are filtered out and the contrast is also enhanced. Reflections and mirroring are minimised, which allows icy surfaces and dangerous situations to be seen much better.
