How EnChroma was invented

EnChroma Chief Scientist and co-founder Don McPherson, Ph.D., had no inkling that his love for playing Ultimate Frisbee would send him on a lifelong mission to help the color blind. Don was playing Ultimate Frisbee while wearing special eyewear he had developed to protect the eyes of doctors from lasers during surgeries. He liked how the glasses enhanced colors. One of his teammates – who is color blind – asked to try on the glasses. He marveled at all the colors he could see that he had never seen before. A light bulb went on. Don began exploring why the glasses might help the color blind better see colors. Co-founder Andy Schmeder, CEO, joined Don and developed sophisticated computer models that simulated wavelengths of light and color vision deficiency. With the support of three National Institutes of Health (NIH) SBIR grants, EnChroma was born seven years later in 2010.
