ok, just so you know what the 20/20 means:
the first 20 is the distance from the letters - 20 feet
The second 20 is the size of the letters you can read in a measurement called pica.
The smaller the second #, the smaller the letter, thus the better your sight.
I believe the big E is 20/400. In Virginia, anything worse than 20/450 is legally blind, according to a show I saw on TV about Lasik.
Anyways, I've had so many exams that I know the letters by memory now.
The 20/20 line is FELOPZD
The 20/15 line is DEFPOTEC
