When I was nine, I was diagnosed with intermittent alternating bilateral exotropia. In the 1950’s there weren’t as many therapies available as now. Mild prisms were put in my glasses to relieve some of the strain, and I was told to move my finger to my nose and watch it to strengthen the muscles. I couldn’t cross my eyes to focus on my finger as it neared my nose, so I gave up.
I could feel my eyes taking turns wandering out when I was tired. But my eyes compensated by alternating the outward turn from one eye to the other, and I was able to do what I loved most: read. Every week you’d find me walking from the library with an armload of books.
