At Legends 4.0 we use BPI lens tinting solutions for optimal results.

LENS TINTS
BPI® Molecular Catalytic™ Tints
BPI® tints remain the industry standard for quality, fade resistant colors.
The unique chemical structure of our tints makes them more stable and reduces tinting time. The tint molecules bond to the lens and becomes part of the lens structure. The lens actually cures in the tinting process and has a more scratch resistant surface.
