1. Locate the blind spot for each of your eyes by drawing a small dot on the left side and a small "x" on
the right side of an unlined, white index card. Hold the card about 20 cm (~8 in) from your face, close your right eye, and look at the "x" with your left eye. Move the paper slowly toward your face. When the dot is no longer visible, its image has fallen on the blind spot of the left eye. Repeat the process with the left eye closed and right eye open while looking at the dot. When the "x" disappears, its image is focused on the blind spot of the right eye. Were you able to find your blind spot for each eye? What is the blind spot?
