Sue Barry: Gaining 3D Vision for the First Time at 48

For as long as she could remember, Sue Barry struggled with her vision.

Cross-eyed from infancy, she went through three surgeries by age seven to make her eyes appear straight. On the outside, things looked “fixed”. But inside, her vision was far from normal.

Because her eyes never pointed to the same place, she could only use one at a time. Her brain couldn’t combine the two images, leaving her “stereo blind”, unable to see in 3D.

“Because my two eyes were looking at different regions of space, the information couldn’t be combined between them, and so I didn’t have stereo vision. I couldn’t see in 3D. I was stereo blind.”

This made everyday life overwhelming:

  • Reading was exhausting, the letters often seeming to move on the page
  • Riding a bike or rollerblading felt terrifying
  • Learning to drive was a nightmare
  • The world looked flat, cluttered, and compressed

School was the hardest of all (did we mention yet that she is now a professor?!). After struggling on a standardized test in second grade, her principal told her mother she needed “face facts” that Sue was a “dim child”. She was placed in a class for children with challenges, where expectations were low and her potential was overlooked.

Finding a Way Forward

Despite the labels, Sue’s mother refused to give up on her. She taught Sue to read at home, patiently working with her until she could keep up with her classmates. With time, persistence, and an excellent memory, Sue excelled academically eventually becoming a college biology professor.

For years, she built her life minimizing the difficulties her vision caused. She avoided driving whenever possible. She rarely looked into the distance because everything seemed to jitter. And she never truly looked people in the eye.

By her 40s, Sue knew something had to change. Teaching, parenting, and driving her children made it impossible to keep avoiding the world around her. That’s when she discovered a developmental optometrist and began Vision Therapy.

The Transformation

The results of her targeted vision therapy were profound and unexpected.

Through targeted vision therapy, Sue finally learned to align her eyes so they worked together, sending correlated, not conflicting information to her brain.

And then, at age 48, something she thought was impossible happened: Sue began to see in 3D!

“The changes with vision therapy were just breathtaking. To my astonishment, I began to see in 3D — at 48 years old.”

With her new found vision everything changed for Sue, and the world opened up:

  • She could see the space between objects – rooms, trees, and landscapes suddenly looked expansive and alive
  • Reading became comfortable, without fatigue or moving letters
  • Driving was easier and safer, with a broader awareness of her surroundings
  • She felt immersed in the world, connected in a way she never had before

“It wasn’t just that I had a new view of the world. I had a new feeling about the way I felt in the world. Stereo vision gave me a sense of immersion.”

Even social interactions shifted.

“Before, I never really looked people in the eye… now I actually look people in the eye, and it makes the world a lot friendlier place.”

Inspiring Others

Sue once believed she was trapped by her childhood condition. But vision therapy taught her that she was not a victim of visual fate. The brain can learn, adapt, and change even decades later.

“Something I wish I knew is that I was not a victim of a visual fate sealed in early childhood. With vision therapy, I learned how to see in a new way.”

Her remarkable story caught the attention of neurologist Oliver Sacks, who profiled her in The New Yorker as “Stereo Sue”. Later, she published her own books, Fixing My Gaze and Coming to Our Senses, to share the science and hope of her journey with the world.

Her story has since inspired countless others with binocular vision problems to seek help and discover that change is possible.
