Part 1 - Susan Barry, author of FIXING MY GAZE: A Scientists Journey into Seeing in Three Dimensions
Sue Barry was cross-eyed from early infancy, and lived for almost 50 years without stereovision--i.e. unable to see in three dimensions. Fascinated as a student by the inner workings of the brain, Sue grew up to be a neurobiology professor. She even used her own vision deficiencies as a classroom example to illustrate the idea that the brain is hardwired at a very young age and cannot be changed. But Sue's faith in the science of the day (a hardwired brain) would eventually crumble. At the age of 48, Susan Barry gained stereo vision with the help of a developmental optometrist who prescribed a program of optometric vision therapy that taught her how to coordinate her eyes.
