Guardino, whose mother is a nurse and father is a “pizza delivery man,” spent his first 12 years blind owing to Leber congenital amaurosis, a rare retinal ailment. Doctors eventually incorporated a healthy gene into his eye after revolutionary research at the University of Pennsylvania’s Scheie Eye Institute, and he restored his sight.
