A Neat Trick To Determine Your Dominant Eye

It turns out that not all eyes were born equal, and that most of us have one dominant eye. The dominant eye, is the one your brain prefers when it comes to processing visual input, and you should probably use that eye when looking through the viewfinder.

A Neat Trick To Determine Your Dominant Eye

Here is a neat trick you can preform to discover which of your eyes is the dominant one. Courtesy of reddit user ElementK.

  • 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 like this.
  • With both eyes open, look through the triangle and center something such as a doorknob in the triangle.
  • Close your left eye. If the object remains in view, you are right eye dominant. If closing your right eye keeps the object in view, you are left eye dominant.

What are you? A lefty or a righty?

    Left eye dominant… perfect. the controls of my nikon d3200 are easier to reach because of the way i position my head with the camera.

    Probably because their comments have proper spelling and grammar – I know, this must be confusing for you.

    Doesn’t seem to make a difference for me, I’m getting mixed results.

    There are two totally different thoughts on this method. I’ve always believed my right eye is the dominant eye and the tests I’ve used are like the one above. I close my right eye and the object doesn’t move, close my left and it does. S/B right eye dominant. But on a WiKi search, it said just the opposite. So did an optometrist that just gave me an eye test. She said the eye that made the object jump, ie., the one you can’t see it, is the dominant eye, as did the WiKi search. I respectfully disagreed with her and she seemed put off that I would question her. So any doctors out there to settle this?

      I’m not a doctor, but I am studying this type of stuff at uni and I’d say that your optometrist is wrong, you see more through your dominant eye therefore the image shouldn’t move. Your recessive eye will see less because it isn’t as widely used. You automatically look through your dominant eye for microscopes etc, and for me this is my right eye, which corresponded with my results, so yeah. I’d disagree with her.

    Left eye dominant. Usually left handed, but with a fair amount of ambidexterity.
