What are the main features of mountain glasses with photochromic lenses:

  • Dynamic lenses: Using a photochromic mountain lens that adapts based on the weather and light conditions present on the route is the best choice from a technical and comfort point of view that a mountain lover can choose. The photochromic lenses of the 2-4 mountain glasses are specialphotochromic lenses starting from the protection categoryone in non-working phase 2 (equivalent to the darkness of an orange lens) and then darkens based on UV and light intensity until reaching category 4 (only if necessary). The maximum darkness that the photochromic mountain lens (category 4) is able to reach represents the lens commonly chosen by those who practice mountaineering or glacier excursions.
    However, this type of lens can also be used for the practice of trekking at lower altitudes because the lens darkens only "as necessary" reaching category 3 in case of intense sun, but raising the level of protectionone with increasing altitude or light intensity.
