What Letter?

My youngest daughter just had another eye check last week. Some people may be wondering how does the doctor check for a young child’s vision if the kid is still learning his/her alphabet. I had the same question, too. Anyway, the short answer is that the child simply tries to point at a similar letter from a small chart (but with jumbled letters) which is held close while the doctor points at the distant letter chart. Anyway, at the end of the checkup, we were told that she should simply continue wearing here eyeglasses until her next schedule visit.
