THE STORY OF ALPI GLACIER SUNGLASSES

Eye protection is serious stuff!Based on a study: ""Ocular phototoxicity and altitude among mountain guides""; Three important points to remember:- The intensity of the sun's rays increases by 12% every 1,000 m.- In addition to the direct radiation, your eyes are also exposed to the reverberation of the UV rays from the snow- With the tinted lenses, your pupils are open wider and more sensitive, so you must wear your protective shields on glaciers.

Designed for mountaineering with their wide field of vision wrap-around frame and shields. Thanks to the 2-4 photochromic lenses you can clearly see the relief of the terrain under all conditions!
