The particular construction of the lens is aimed at better protecting the eye from all UV-A and UV-B rays which become much more intense with increasing altitude, due to less shielding from the atmosphere. For the same factor, the sun’s rays and the intensity of light are also greater, and the category lens is the most performing to protect and ensure the constant sensation of relaxation for the eye even for very prolonged use.

The most extreme mountaineering expeditions require the utmost in technology for every equipment needed for climbing. For eye protection, the category 4 lens or the 2-4 photochromic lens (which reaches category 4 exceeded a threshold of light intensity and UV) is generally chosen because if adequate filters are not used, there is a risk of severe irritation to the eyes, which could lead to bring to a stop even a well prepared alpine expedition.

(Reference is made to extreme expeditions such as Everest, K2 and very high altitude peaks).
