Thirteen doctors and researchers have won the Sanford and Sue Greenberg Prize to End Blindness and will share the reward of three million dollars in gold. The winners were chosen based on the strength of their contributions to eliminate blindness, the ambitious aim set out by the prize organizers in 2012.

“I believe that we are so much closer to achieving that goal,” says co-organizer Sanford Greenberg, chair of the board of governors for the Johns Hopkins University’s Wilmer Eye Institute. “It’s quite extraordinary.”

The prize is part of Greenberg’s life-long mission to prevent people from losing their sight. In February 1961, when he was a 20-year-old college student, he suddenly went blind due to glaucoma that had been misdiagnosed.
