Schoolteachers are legendary for their "eagle eyes" — their uncanny ability to see a note being passed in the last row or a piece of chewing gum being placed surreptitiously in a student's mouth. So it was for Barbara Brown, a retired teacher from Virginia, until about four years ago when she began to experience severe eye irritation.
"It started with what I thought was an eye infection," Barbara said. "I got some ointment from my doctor, but it didn't get any better. He finally sent me to a specialist who diagnosed my problem as ocular rosacea."
