If you wear glasses, you're in a majority in most developed countries. In developing countries, few have them, but many need them. By some estimates, two billion people in developing countries need eyeglasses, but don't have access to them. One of the groups working to bridge the gap is VisionSpring, a social enterprise that has already sold 3.7 million pairs of glasses, at affordable prices, to people in Africa and Asia making $4 or less per day, helping improve learning, work productivity, and quality of life.
