The Aborted Test

While performing a complete physical, including the visual acuity test, the doctor placed the patient twenty feet from the chart and began, "Cover your right eye with your hand and read." The patient read the 20/20 line perfectly. And the doctor said, “Now your left eye." Again, a flawless read.

Then the doctor requested, “Now both." And there was silence. The patient couldn't even read the large E on the top line. The doctor turned and discovered that, the patient had done exactly what he had asked; he was standing there with both his eyes covered. The doctor laughed too hard, to complete the test.
