I gots strabismus. The muscles that move my eyes were formed very unevenly. Therefore, one eye was always off-axis. There is one baby picture of me in particular where this is fairly obvious: a small child wearing pajamas in your typical photographer's studio, a smile on his face, right eye looking straight ahead and the left one pointing towards his nose. It's the kind of thing you'd expect on the front of a card from the "humor" section of Hallmark, with some supposedly witty saying on the inside.

When I was two years old, I had surgery to correct this. While the treatment was successful, evidence of the disorder still exists. Since my eyes were not parallel during my early development, I never learned to see with depth perception. Sometimes I consider this a blessing: a head mounted display would cost half as much for me, and every movie is a 3D movie. To this day, if you see my eyes wander, you'll know that I'm tired, sad, or inebriated.
