Can you change eye dominance?

Check your eye dominance (its fun)?

• * Extend both hands forward of your body and place the hands together making a small triangle (approximately 1/2 to 3/4 inch per side) between your thumbs and the first knuckle. * With both eyes open, look through the triangle and center something such as a doorknob or the bullseye of a target in the triangle. * Close your left eye. If the object remains in view, you are right eye dominant. If your hands appear to move off the object and move to the left, then you are left eye dominant. * To validate the first test, look through the triangle and center the object again with both eyes open. * Close your right eye. If the object remains in view, you are left eye dominant. If your hands appear to move off the object and move to the right, then you are right eye dominant.

• Answer:

  Here's an interesting twist to it - if you close your left eye then your right, you can alternate between the two lines of sight. Now open both eyes and consciously shift your point of view from right eye to left eye. It's hard to do at first, but once you get the hang of it it's sort of cool. I am so left eye dominant that if I put a patch over the left eye, within about 15 minutes I go "blind" - that is to say, my brain gets tired of trying to see out of the right eye and shifts to the left - resulting in me seeing only the back of my closed left eyelid, despite the fact that my right eye is open. (I found that out when I got a cat scratch in my left eye and needed to cover it). That is another interesting experiment.
