With both eyes open, point your finger at a distant object. Close one eye, then switch and close the other eye. Your finger should appear to move off or away from the object when one eye is closed. If the finger does not appear to move, then the eye you closed is your nondominant eye. Another variation of this test is to stretch your arms out in front of you and form a triangular-shaped hole with your fingers. Look through this hole at an object about 10 feet (3 m) away, keeping both eyes open. Without moving, close one eye, then the other. The object should appear to move, possibly out of the triangular window, when you close one of your eyes. If it moves, then you are looking through your nondominant eye. This test examines which eye you use to focus on objects that are 10 feet away. You can easily perform it on yourself at home.  Cut a hole in a piece of paper that is about an inch and a half in diameter. On a second piece of paper write a single letter so that it is roughly one inch high. Tape or tack the paper with the letter onto a wall at eye level. Measure a distance of exactly 10 feet away. Stand 10 feet away from the letter on the wall. Hold the paper with the hole in it at arm’s length with both hands. Your arms should be parallel to the floor. Look through the hole in the paper at the letter in the wall. When you can see the letter, have a friend cover first one eye, then the other. Don’t move or adjust your position. The eye that can see the letter is your dominant eye. If you can see it with both eyes, then neither eye is dominant in this task. This test is similar to the distance test, but it examines which eye you use when focusing up close. You can also do it with quickly and easily with household objects.  This test can be done using a thimble, shot glass, or similar household object. Write a single letter on a piece of paper so that it is about 1/16th of an inch tall and wide. Tape this letter to the bottom of the inside of the thimble or shot glass. Cover the thimble or shot glass with...
