Then I put on the glasses. Unbelievable! … It was like a peek into a world I knew existed, but had never been allowed to see.

With my Enchroma sunglasses, I can see the three distinct colors of a stoplight for the first time, and red stop signs and lit brake lights jump out with a new urgency.

The EnChroma Story

Over a period of more than ten years of focused R&D working under an NIH-sponsored small-business innovation research grant, the EnChroma team (led by Dr. Don McPherson, Ph.D) approached the problem of color vision deficiency from a rigorous scientific foundation. We used the latest understandings of the genetic basis of CVD to create a sophisticated computer-based model of human color vision, and then set out to solve the general problem of determining the optimal spectral filter for any given set of conditions.

Using our patent-pending design methods we are able to design complex spectral filters to assist color vision for a wide variety of applications. Our lenses are designed to provide the maximum possible performance while also maintaining consistent and attractive color appearance and meeting necessary safety requirements for general use eyewear.

EnChroma’s mission is to leverage our lens technology platform and understanding of human color vision to create innovative eyewear products that help people see the world better.
