• Fototech BRN Lens are made with NXTTM e VARIATM technology, undergoing a heat polymerization process that al-lows inﬁnite transitions, unlike photochromic ﬁlm lenses, which have a limited number of transitions.
• Thanks to VARIATM technology, lenses are really adaptive to light changes, ensuring the maximum comfort
• Photocromatic Range: 78%
• Transition form transparent state (77% Tv – Category 1) to dark state (17% Tv – Category 3) take place in 30 seconds
• Perfect for both outdoor and indoor usage
