Dubbed “Stereo Sue” by neurologist Oliver Sacks in a New Yorker article by that name, Sue Barry has gone on to write her own book Fixing My Gaze which describes the astonishing experience of gaining 3D stereovision after a lifetime of seeing in only two dimensions. Intensive vision therapy created new neural connections, and with them, a new view of the world. Challenging conventional wisdom that the brain is programmed for life during a critical period in childhood, Barry offers a poignant and revelatory account of our capacity for change.
