In America, we all know Helen Keller. But we don’t know the more than 200,000 blind children in India. We don’t know that blind children in India do not go to school; that many end up begging on the streets (if they are of the “lucky” half that survives past the age of five). We don’t know that many of these blind children have easily curable disorders, like cataracts. But Pawan Sinha, founder of Project Prakash (meaning “light” in Sanskrit), saw what we have all been blind to. He saw a chance to help these children by providing free medical treatment to restore their vision. However, because the brain's ability to process visual information emerges early in development, there was one question that Project Prakash would need to answer: After removing cataracts from an older child, would the brain still possess the ability to learn how to interpret visual signals in order to recognize objects?
