When I was in the sixth grade, I lost the sight in my right eye during a playground mishap. Fortunately, the accident had little effect on my life. When I reached my 40s, however, I needed to get glasses.
At the optometrist’s office, the doctor’s young assistant pointed to an eye chart. "Cover your right eye and read line three," she said.
"I’m blind in my right eye," I told her. "It’s a glass eye."
"Okay," she responded. "In that case, cover your left eye."
