Tonic Colour Filter System

TONIC Glass Photochromic Polarised Grey lens incorporates a 3 Colour Integrated Polarising Filter system using the colours: Green - to retain colour, Aqua - that acts as a splitter to define colour where it normally flattens out, and Grey - that gives deep contrast whilst activating the Photochromic properties. The TONIC Glass Photochromic Polarised Copper lens incorporates a 4 Colour Integrated Polarising Filter system using the same 3 colours as the Grey with an additional Yellow - that enhances colour.
