How Mark Changizi Conquered Colorblindness With Glasses
This article originally appeared on io9. A pair of researchers from 2AI Labs have developed a wearable eyeglass device that effectively cures red-green color blindness. Called O2Amps, the technology works by leveraging our capacity to see the amount of oxygen in another person's blood by simply looking at the hue of their skin. Developer Mark Changizi came up with the unorthodox idea after considering the evolutionary underpinnings of color vision. His unique theory eventually led to the development of eyeglasses that enable wearers to perceive emotions and social cues more clearly - and, by unintended consequence, to solve the colorblindness problem. We contacted Changizi to learn more. One of the more fascinating aspects to this breakthrough is how it came about. Changizi, author of Harnessed: How Language and Music Mimicked Nature and Transformed Ape to Man, has a long history of investigating the various ways humans think, feel, and see. He has...
