Card on Eye Exam

Yesterday, I got my first class medical renewed. On the eye exam, there is a card that has numbers and tick marks, and I was required to say which number a line crossed (numbers had a range probably from 15 to 30ish). What does this test? I was fine, but what does it mean if someone gets too far to the left or right? Is this test required for the ATC second class also?

That is problably a measure of phoria or the balance of eye muscles.

Without giving away too much information, when I tested, I still fell in the acceptable range but pretty close to the cutoff. I believe the cutoff is 18, and I saw 19. What does that mean?

There are several measures out there. The numbers are relative for each test, so I cant comment other that the fact you passed and it should not get worse with age.
