Dominant eye discovery

Hold your hands out at arms length. Form your hands so you make a triangle between your index fingers and thumbs. Look at an object through the triangular hole you have formed. Without blinking bring your hands back to your face. They will automatically go to your dominant eye. Works everytime.

Who can see the tip of their nose??? I sure can't.

Works every time, for folks which have a dominant eye. Some folks don't.

Here's an interesting little study (with plenty of references) that draws this conclusion:

5. Conclusions
In conclusion, we found better performance in a visual search task for the dominant eye. These results suggest that the dominant eye has perceptual processing priority, arising from enhanced salience of the perceived target. In addition, we found the surprising result that representations of elements presented to the dominant eye inhibit the input that arrives via the non-dominant eye. These results contrast the suggestion made by Mapp et al. (2003)that eye dominance has no effect in performing binocular tasks, but only affects the eye that will be preferred for performing a monocular task. The findings are even more significant when one considers that all potential subjects were screened for eye-dominance using the hole-in-the-card test. That is, we used a monocular, not a competitive binocular test for choosing subjects and determining their dominant eye. Finally, these effects work at long range and thus are probably based on high level mechanisms.

These principles may be used in practice when designing visual displays. If a task is to be performed monocularly (as in looking through a telescope or microscope) then participants should use the dominant eye; (see also Mapp et al., 2003). However, when we can introduce information to both eyes, separately, then superior performance may be obtained by having target information introduced to the dominant eye and non-target, noise, introduced to the other, non-dominant, eye. This may be implemented, for example, by having the viewer identify a target at one moment, and having it presented from then on to the dominant eye while other objects are presented to the non-dominant eye.

So, by definition you're schizo-optic.

Actually, that study does support that; it states that eye dominance can change with the angle of viewing.

That's how we teach it for 4-H. I wish they'd have done it back when I was young. It was "You vill shoot right-handed und you vill enchoy it!" I am left eye dominant.

The research has been out there for decades - a small percentage of us are non-dominant. I fought with shooting coaches and instructors for years, the world was flat to them, and they've been happy to burn any witch who didn't fit into the right or left paradigm - much like the way you decided to attack my post.

When my eyes were younger, whichever way I viewed relative to my face would take over - meaning any time I would shoulder a long gun, my face slightly angled, my OFF gun eye would take over. As I've aged (including multiple head trauma's, so take your pick on what's getting rewired), it's typically more on an hour by hour or day by day scale, rather than minute by minute or second by second. It does respond almost immediately if I change from contacts to glasses to prescription safety glasses.

Not great when you wake up on match morning and the wrong eye takes over... but it's an advantage most of the time.

Hold your thumb up like the front sight on a rifle, and quickly cover an object in the distance with your thumb. Close one eye, then the other. Whichever eye lines up with your thumb that is covering the object in the distance, that is your dominant eye.

The first thing we did in teaching shooting is determine both the dominate eye and hand. We always teach shooting with the dominate eye. Rarely eye dominance can be altered by physical state as in eyes tired or other visual impairments. A common solution is tape or grease on the non dominate eye lense of shooting glasses. I have never seen a case of neither dominate but do not doubt such mutants (JK) exist. I am strongly right eye, but if my eyes are tired they get confused I may even see double.

left eye dominant, right handed.
Trying to get some people to do the hole test correctly is difficult. Try this.
Make a dime sized hole in a piece of paper. Have the person hold the paper at arms length and look at an object through the hole. Tell them to slowly bring the paper to their nose while always having a visual of the object. They will realize which is the dominant eye before the paper touches their nose.

This right here.

Sometimes I have people look at my own dominant eye through the triangle and I can see right there which one is dominant.

Then I have them close their [non dominant] eye.
"Still see me?"
Now close you [dominant eye]
"how bout now?"

There you go!

Me, too. I can force a change in a few hours by smudging the lense of shooting or sunglasses over my left eye, and it'll stick for at least a few days.
