BPI Therapeutic Lenses and Tints

An index to information on the benefits of tinted lenses

Colored sunglass lenses have been in use for at least a millennium. The Roman emperor Nero is said to have worn polished gemstones through which he watched gladiators fight.

More recently, Brain Power Incorporated introduced a wide selection of tinting colors for plastic lenses. BPI labs have discovered that some colors of tinted lenses had useful properties beyond shielding the eyes from bright sunlight.

Scholarly articles as well as less formal web pages have appeared describing the benefits of using sunglasses tinted with certain colors. This website serves as a clearinghouse linking you to these posts so that you may find a sunglass tint or color which helps you.

We only cite these posts, but we take no responsibility for their contents. Before trying anything, regard the source of your information.
