Information is not processed and transmitted to the brain by both eyes equally. One of your eyes, the dominant eye, carries out these actions a few milliseconds faster than the other. Those individuals whose dominant eye is on the same side of the body as their dominant hand are considered same-side dominant, while those whose dominant eye is opposite that of their dominant hand are considered cross-dominant. Eye dominance can affect such motor skills as a person’s ability to aim and to focus.1 The dominant eye drives visual fixation, such as what is used when following a baseball falling through the air to a glove.
This lab provides a simple method for discovering which eye is dominant.
- Small object that can be seen on a wall
- Find a small object, such as a clock, on a wall.
- Stand directly in front of it, approximately 10 feet away. Once you are in this position, create a small triangular window with your hands by overlapping your thumbs and fingers.
- Stretch your arms in the direction of the wall so that you can see the object through your triangular window, as in the figure below.
- Close one eye, and then open it. Repeat with the other eye. Your dominant eye is the one you used when the object remained in the triangular window.
