Molecular Catalytic Dyes

BPI dyes remain the industry standard for quality, fade resistant tints. The unique chemical structure of our dyes makes them more stable and reduces tinting
A carbon molecule shares an electron with a carbon molecule in the hard resin plastic lenses. Thus, the dye bonds to, and becomes part of the lens structure. The lens cures in the dye process and has a more scratch-resistant surface.

The dyes are available with these colours :
Brown, Green, Grey, Pink, Red, G-15, Black, Yellow, Blue, B&L Lavender, Fuchsia red.

Also available EVA 1 and EVA 3 which can reduce eye strain while using computer.
