With the Lutina Photo lenses, Tokai has decided to take advantage of cutting-edge technology to combine the advantages of Lutina with the dimming capabilities of photochromic lenses.
The result is versatile and comfortable lenses, which combine the advantages of protection from UV rays and high-energy violet light with the elimination of the hassles associated with changes in brightness. The transition between different weather conditions (from cloudy to sunny) and the transition between closed and open environments is made smooth and comfortable by the rapid activation speed of the lenses.
In bright conditions, grey quickly changes from 10% to about 85%, brown from approx. 10% to 77% absorption in transmittance range.
