Can These Glasses Really Cure Colorblindness?
Approximately 8% of all men in the world suffer some form of colorblindness. It affects even fewer women. There is a startup from Berkeley, California called EnChroma that aims to help those with colorblindness. According to Donald McPherson, Ph.D., who is EnChroma's cofounder and vice president of products, these glasses work by "reestablishing the correct balance between signals from the three photopigments in the eye of the color deficient." In simpler terms, colorblind people don't receive as much red or green light as the average person, and the EnChroma glasses selectively filter light to correct that.
