DEAR ABBY: I want to thank you for a letter you published in 2007. It came from a woman saying her daughter had “convergence insufficiency disorder,” in which the eye drifts and causes double vision. I was 61 and had that problem, but I never knew what it was.
I would get headaches from reading and did poorly in school. A teacher once suggested my mother have my eyes checked. The doctor gave me the standard eye chart test, which showed nothing. He recommended more tests, but Mom reasoned they would find nothing and be a waste of money. She insisted I was lazy, and believed corporal punishment would make me study harder.
