Cross-eyed since early infancy, neurobiologist Susan Barry saw the world in a very different way. Although she had three childhood operations, the pathways in her brain that allow for binocular vision did not develop normally; instead, she saw a flat, 2D world. Over 40 years later, she defied expectation by teaching herself to see in 3D. She recalls this experience in Fixing My Gaze. She has been featured on NPR and in a New Yorker article by renowned neurologist Oliver Sacks entitled “Stereo Sue.”
