Sunglasses 3F Photochromic 1225z

3F Photochromic 1225z self-tinting sunglasses

Elegant white and black design of Photochromatic sunglasses. The 3F Photochromic sunglasses have specially treated lenses that prevent your eyes from being dazzled by reflected light.

Self-tinting lenses ensure safe movement in the field. The lenses actively react to the intensity of the outdoor light and adjust the intensity of the lenses' coloration on a scale of 2 to 3. They also use a polarizing filter that absorbs reflections from shiny surfaces (cars, water surface, glass...).

The lightweight and flexible Grilamid TR 90 material from which they are made only underlines the high user comfort for anyone who wants to feel safe at sea or in the snow, while driving, cycling or hiking. Of course there is UV protection 400 (UVA, UVB, UVC).

The 3F Photochromic 1225z goggles also come with interchangeable clear lenses and a hard case for the goggles.

Different filters transmit different amounts of the sun's rays:

filter 0: transmittance 80 to 100% - colourless or very light filter
filter 1: transmittance 43 to 80% - light filter
filter 2: transmittance 19 to 43% - medium coloured filter
filter 3: transmittance 8 to 18% - dark filter
filter 4: transmittance 3 to 8% - very dark filter, not suitable for road use
