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. TONIC optically ground decentered glass lenses, Vistaview™, are a lightweight 1.7mm thin glass, designed for wearing all day long and extremely light weight that you wouldn’t know they are actually glass. All TONIC Polarised glass lenses have an antireflective coating on the back surface of the lens, reducing back surface reflection by 45%.

How the Tonic Photochromic Lens adjusts to conditions.


TONIC Glass Photochromic lenses, Copper or Grey, darken and light depending on ambient light conditions. These lenses have been designed and developed to give the highest quality optics in all conditions. Looking through TONIC Photochromic lenses you will see that the colour saturation for reds, blues and greens is more vibrant than ever before. Team this with TONIC Arc™ to absorb dangerous reflective glare from entering your eyes and the decentered properties of our lenses for accuracy and depth gives you, the wearer and view that is truly overwhelming.

In bright sunlight the lens is exposed to both visible and UV light. The lens changes to a darker shade and moves to its darkest state with an 86% tint. This means 86% of the light is blocked and only 14% passes through the lens to you eye providing maximum protection against intense sunlight

In low light conditions the lens moves to 67% allowing the maximum amount of light to reach your eyes providing optimal daytime vision in cloudy or low light overcast conditions.
