Dye, BPI FL-41 Therapeutic Tint, (4 Ounce Bottle)

A rusty rose color that is usually tinted to a darkness of 50%. It has been found useful to reduce eyestrain, tension headaches and migraine. It is thought that the flickering blue light of much indoor lighting is a trigger for these complaints. This filter blocks about 80% of that component.

The unique chemical structure of BPI tints makes them extremely stable and accelerates tinting time.  These tints bond to the lens and become part of the lens structure. The lens actually cures in the tinting process an has a more scratch resistant surface.  BPI tint concentrates are available in more than 188 colors.
