I can put your prescription on and test to see if i can see the 20/20 letter size. If the smallest letters i can see are 20/30, then you see 20/30. The prescription your doctor gives you will allow you to see i best. Just how well i see depends on the health of the eye and many other operational functions in i eye and brain.

You need to know at least something about the size and shape of your eyes and the power needed.
