DOME Replacement Photochromic Polarized Lenses Cat.2to4


Type: Photochromic Polarized CAT. 2-4  lenses DOME model




The photochromic lenses 2-4 are special photochromatic lenses with a smoke base color able to reach category 4 during the maximum work phase. The starting color is a very light smoke that allows the correct vision even in areas with strong shadow or very low brightness, and in the phase of maximum work is able to reach category 4 with the optimal conditions of light and UV generally used for Mountaineering and Volo sports to better protect the eye at high altitudes.

As for the common photochromatic lenses also the photochromic lens 2-4 exposed to UV radiations and to sunlight in general, initiates a reversible chemical reaction that darkens the surface of the lens until reaching category 4 (when necessary). Once the irradiation of light and UV is finished, the lens gradually returns to the original color state.

The polarized lens offers protection from UV rays, but not only: in fact, this special type of lens is able to concentrate or diverge the light rays and to attenuate the UV-A and UV-B radiations through a polarizing filter that eliminates the transverse reflexes.

The advantages of polarized lenses are:

  • Better perception of contrast
  • Clearer vision
  • No modification of natural colors
  • Elimination of transverse reflexes

Polarized lenses are very performing for hiking, also especially when the UV are more intense, they allow a greater relaxation for the eyes even for very prolonged use and with very intense light conditions.
