eye dominance and loupes

When you bring a loupe close to your face for viewing a coin, do you prefer using your dominant or non-dominant eye?
Shooting billiards, a rifle or handgun, a telescope and photography also depend upon eye dominance. So a related question:
When you take aim with a rifle, both eyes open or one eye open?
How about when using a loupe?
Edit: Your weaker eye is not necessarily your non-dominant eye. With both eyes open, point to a distant object. Then close each eye and the dominant eye will be the one that points to the object you selected. It has nothing to do with vision acuity (20/20 or 20/50) or with handedness (Left or right parity).

With my 10x I use it alittle farther from my eye and I use both eyes.
For a rifle with a scope, its my dominant eye. For pool both eyes. For a handgun both eyes aswell.
With my coin scope its both eyes too.
Pistol, I use my left eye when target shooting - tactical range usually both open.
M-16 or other non-scoped rifle and shotgun, I keep both open.
M203, M60, 50-cal, or other big guns were usually both open.
Scope/Sniper rifle, left eye.
Pretty sure shooting pool, I don't close one, but will have to check next time I'm playing.

i did the test!
I use my right eye with a loupe, both eyes open, just checked.
In honor of the memory of Cpl. Michael E. Thompson
For photography, I will also switch, but I notice that I have a significantly different artistic view between left and right. My right eye tends to see more details of the picture while the right eye tends to be more overall semmetry or artistic beauty.
It's quite likely that one eye versus the other actually pick up coins differently, but I've yet to discern that yet.
You wouldn't believe how long it took to get him to sit still for this.
Because I'm right handed, and always hold the loupe in my right hand, it makes more sense to stick it under my right-eye than cross it in front of my face to look through it with my left.
I only use a loup with my dominant eye, same with a scope. Open sights both eyes are open, epecially so bird hunting with a shotgun.

the real question is which eye does the tpg's use?...
or is it "do"

I'm sure it's up to each individual grader to determine which eye they are most comfortable with.

i could just see the grading room now. on the wall in bold letters PLEASE USE DOMINATE EYE WHEN GRADING THRU LOUPE!..
Hoard the keys.
This improves acuracy and speed while reducing eye strain. It's easy to learn.

Believe it or not, most coins at the major TPG companies are graded without any magnification.
