Part optics, part neuroscience, EnChroma® glasses unlock a new world of color for people with color blindness. Our glasses are designed to make you look good, too, so better color vision can be a seamless part of your everyday routine. The EnChroma lens technology is based on over a decade of research effort to understand the causes of color blindness and how to engineer an optical technology platform to address the problem. The underlying cause of most color vision deficiencies is due to the red and green-sensitive retinal cone cells having an overlapping response to light. Instead of responding separately to each wavelength of light, their response is highly similar. To compensate for the overlap, the EnChroma lens contains proprietary optical materials that selectively remove particular wavelengths of light exactly where the overlap is occurring.
