Transitions Photochromic Lenses Available in New Graphite Green

By
 
DALLAS—Essilor and Transitions Optical have partnered to develop and launch Transitions Signature VII lenses in a graphite green color. Using a special dye formulation, the lenses provide natural vision and true color perception in a variety of light conditions.

The iconic green color dates back to the 1930s when it was applied to sunglasses worn by U.S. Navy pilots. The gray-green shade was originally developed based on research that showed how human eyes respond differently to various colors in the visual spectrum. The lenses were then formulated to emphasize certain colors to help pilots locate and track objects against a variety of outdoor backgrounds such as earth, sky and water.

Transitions Signature VII lenses in graphite green were developed using Chromatic Color Adaptation technology and Chromea7 technology. Chromatic Color Adaptation technology is a method used to evaluate tinted and photochromic lenses. Chromea7 technology is a molecular formulation which enables Transitions Signature VII lenses to be more responsive to changes in light outdoors, reduce glare and enhance contrast to reduce eye fatigue and strain and get even darker in higher temperatures. ■
