BPI Lens Prep II conditions plastic lenses with a special ionizing agent that leaves a positive charge on lens surfaces. This enables the lenses to quickly and evenly absorb negatively charged BPI Molecular Catalytic tints. BPI Lens Prep II dissolves oil and grease. Can be used cold, but works best when heated in your lens tinting instrument.
