My husband has close set eyes. How far do they adjust. I don't know the correct terminology, but how close can you get the eye ends together?

With the glasses pushed together as close as they can go, I measured from the center of one of the glass lenses to the center of the other one and it was 2 3/8". I would think way too close for the average adult. Hope that helped.

When the bins are fully closed the centre-to-centre distance of the eyepieces is 2.25 inches which should be sufficient.

IPD - interpupillary distance is usually expressed in mm - not inches. The measurements from the helpful answerers range from 2.5 to 2.25 inches. 2.5 inches = 64 mm 2.25 inches = 57 mmAverage IPD for males is 65 (range 52-78)Average IPD for females is 62 (range 52-76)So- best thing is to try them somewhere or compare your IPD with the actual IPD of the bins.It seems that Nikon does not publish that info - at least no where I can find online.

My husband's eyes are also close-set. He uses the binocs all the way closed. The distance between the center of his eyeballs measures about 2-1/2" ...the same as the eye pieces on the binocs. I hope this info helps

Not too bad to change lenses..a siff firm grip and steady should do it.....will not fit over normal glasses...unless you were colonel klink...with an eyepiece!!

The thing to keep in mind about these is that they are compact. So the eye pieces are set wider than the view lenses. Turn them around.

Not sure how long an eye relief you need. It worked for me between 3 to maybe 4 inches of eye relief. It's nonadjustable magnification. Hope this helps

You can adjust how tight the glasses are by simply sliding the Croakies further up the glasses' arms, closer to the lenses. They're not falling off unless you pull the glasses' arms out of the Croakies. (These instructions will make sense if you get the product). In other words, you should be good.

This is a very complicated answer. I defer to this link.http://www.astroadventures.net/cohen/articles/Wear%20or%20Not%20to%20Wear%20Glasses.pdfWhether you wear glasses or not, each lens that you use requires that your eye be placed at an optimum distance from the lens. Wearing glasses prohibits one from getting one's eye close enough to enjoy the full field of view with some lenses but not others. The preferred method is to NOT wear glasses and each person must adjust the focus for the best clarity. If your wife has an astigmatism, you can switch to higher eye relief lens while wearing glasses or purchase Televue Dioptrx Astigmatism-Correcting Lenses while not wearing glasses. Have her optometrist make her a monocle. This is a very complicated answer.

Yes you can adjust focus on one side to match the other eye. Afer that the normal focus will keep both eyes focused.

im not to sure what eye relief is, but if it is what i think it is... i would say 4 inches.

You may have to use two with that length then trying to ensure both will operate the same is the challenge. You can try one if you can grab the sight close enough to the middle.

Oh ok I seen the other answers wasn't quite sure what you were talking about as I said they are for my husband. The dial to focus them do not move my husbands is just fine.

we've never had a problem, adjust 1 eye at a time for the user. They work great for us

The distance between the center of the pupils when focused on infinity (Interpupillary Distance)is not given in any of the specs for these binocs.Jim

They are a bit tricky to adjust and get used to. Try holding the binoculars and closing your left eye adjust the ring on the right lens till it's in focus then open your left eye and turn the middle dial until both lens are clear. One set up they are great easy to carry and great for distances my son and I used ours all over Bhutan and were very satisfied! Good luck

Hi! We don't have children, so I can't test the binoculars on one (!), but I can tell you 2 things I think might help: (1) These binoculars close together all the way, bringing those 2 eyepieces touching, side by side; and (2) I measured the distance between the center of each eyepiece, and it's about 1-and-1/2 inches, actually just a teeny bit less than that. So, I would assume that if the span between the center of each eye of your child is an inch-and-a-half or more, these binoculars could totally be viewed by someone smaller. :) I hope this helps!

From eye to eye, where they attach is 14 1/8" and 23 1/2" long when opened. Hope this helps.

It looks like they can adjust pretty small. Keep in mind, these do not go over the top of your head, they go around the back of your head. They are the best I have ever had - I have gone through about 30 sets in my life time.

I remove my glasses for all binoculars. I just adjust/focus the binoculars for what I need. These did well for my wife and I.
