Susan R. Barry

Susan R. Barry is Professor Emeritus of Biological Sciences and Neuroscience at Mount Holyoke College. She had been cross-eyed and stereoblind since early infancy but learned to see in three dimensions at age forty-eight by retraining her visual system with optometric vision therapy. Her story was first described by Oliver Sacks in his New Yorker article, Stereo Sue, and then greatly expanded by Sue in her book, Fixing My Gaze: A Scientist's Journey Into Seeing in Three Dimensions. Her most recent book is Coming to Our Senses: A Boy Who Learned to See, A Girl Who Learned to Hear, and How We All Discover the World.
