I am not going to do a poll on this just yet- How many collectors out there use a loupe and close the other eye?
Who leaves their other eye open?

Please do so, I have an inquiring mind...
Count me on the side of both eyes open (looking through left, FWIW).
I used to shoot with one eye closed until I joined the military. Having the field of vision from the second eye can add many, many years to your life span!

<< <i>In the "old Corps" we target shot or sniped with one eye closed, I don't know how well you would do from the 500 yard line with both open. That plinking with both eyes open came a little later, probably with the m16 and "spray and pray." I use a loupe with both eyes open, and bring the piece up to the loupe. >>
We still qualify and snipe (optics) with one eye closed. Regretfully, today's warfare is urban, close-up and fast... my right eye looks through the sight and my left eye looks everywhere else... my brain does the rest. If you miss a target, your beneficiary gets $400,000.

<< <i>To tell the honest truth, I've never even looked through a loupe before, let alone touch one.
Huh? Why not? A loupe is a basic piece of equipment that every coin collector should own and use.

Same here.
<< <i>I keep both eyes open, but I place the lens close to the coin, not my $800 eyeglasses. Anyone else do it this way? >>
They (optics manufacturers) recommend having the magnifying lens equidistant from the object being examined and your eye.
In other words if you have to hold your loupe 3" from the coin to bring it in focus, then you should have your eye 3" from the lens as well.

Interesting, I'll have to try it that way.

<< <i>Both eyes closed. Third eye open. Loupe levitating between coin and zenith of awareness. >>
That is good!
I use one open and one closed...but as I'm getting older, I'm not sure which one will be the "good" eye on any given day.
But I do know that one day my arm might not be long enough for me to adjust the focus enough!!!

interesting,
I put the loupe up to my eye, and thought everyone did.
One eye for me.
We'll use our hands and hearts and if we must we'll use our heads.
However, I prefer to go into a coin deal with both eyes open, so never eat cantaloupe at a coin show.
I have been criticized for using a strong loupe- and I am okay with that criticism because I like what I use- and it seems to work for me. I have never been criticized for how I use it...until recently
I was instructed on how to use a loupe and was told that both eyes should remain open. I was told closing one eye or squinting can cause an issue with how the image is processed and ultimately there could be a descrepancy in what is seen and what is actually there. In other words... you may not be buying the coin you think you are based upon how images are processed.
I know today is April fools day- this event happened well in advance of this so this is not a prank or a joke. Before I lashed out saying this was complete nonsense, I decided to say nothing mainly because I thought remaining polite was the better course of action. And now that I think about it- perhaps others should think about how they look at coins and whether there is something to this.
I know we have some medical experts here that may be able to shed some light on this...

I never use one either. I hold the coin way up close and see all the detail I need to see. When I went in for new glasses(I am so near-sighted it is scary, coke bottle lenses even though I get the slim ones) the optometrist told me my eyes magnify close up. She has never seen anything like it. Made me decide not to have lasik surgery--------------BigE
Youze don' need no stinkin' magna-fracations.
When you look at things with both eyes open, you process them as nature intended, as a stereoscopic version of the thing itself. The processing is natural and the image perceived is easily understood by the brain. Breaking it down into what is seen by the right eye as distinguished from what is seen by the left however, you get this:
The right eye sees the light reflected from an object as it travels from the light source, bouncing off of the subject, and into the right eye. The left does the same.
So, how does this apply to viewing coins? Simple. Keeping both eyes open allows your brain to combine both inputs into a single image. The natural, two eyes open view allows for harmonic combinations of light to form in the mind's eye, forming a more complete and accurate representation. This is especially important to consider when viewing coins (themselves) and coin images.
Basically, when we view coins using a single light source with both eyes open, we hold the coin so that the light is most revealing of the coin itself, usually upright, with the light coming in from out in front of your head. Coin collectors have innately trained themselves to see this as the "natural" look of a coin. This is why photographs of coins with axial lighting, or lit from below look unnatural. Since the light is perceived slightly differently by both individual eyes and then combined for the final mental image, closing one eye does in fact reduce the input and will actually change the mental image of a coin, albeit ever-so-slightly that you may not notice.
One thing that I did discover when learning to photograph coins is that having a light source at 10 and 2 o'clock will yield the most accurate representation of the coin on film. This is because those light positions mimic what the eyes see when they are both open. If you think about it, this makes sense. The 10 o'clock light provides the lighting that is representative of what the left eye sees. The 2 o'clock light gives the right eye info. Combined, it looks natural, and most like holding the coin in hand under a single light.
I hope this helps.

Good eyes bushmaster. The pic of me is at a private family gathering in the middle of the country. No excuse for not wearing the eye protection on that excursion, but I do noramally.
