The nurse tells a patient that he will be performing a visual acuity test using the Snellen eye chart. The patient asks how the test is done. The nurse's best reply is:

"You stand 20 feet away from the chart while I test each of your eyes."

The number beside the largest print read is your visual acuity score!

"I will be testing your vision with your reading glasses on."

"You stand 50 feet away from the chart while I test each of your eyes."
