Read the Chart
A doctor was performing a complete physical, including the visual acuity test.
He placed the patient twenty feet from the chart and began, “Cover your right eye with your hand.” The patient read the 20/20 line perfectly.
“Now your left.” Again, a flawless read.
“Now both,” The doctor requested. There was silence. The patient couldn’t even read the large E on the top line.
The doctor turned and discovered that he had done exactly covered both eyes.
