The largest part of the lens is just under 2". If you had a two inch hole they would have clearance.

The joint in between the two eyepieces can adjust to fit wider or more narrow set eyes, so as long as the distance between his eyes is within normal human range, you'll be fine :)

Eye relief is unlimited due to being 1x. Even at indirect view. As long as the dot is on targetUse mine at about 8 inches.

The glasses can be used for Driving.However the Diopters range is set at-3.0 to + 6.0 perhaps the strength you require is stronger than the range of the Diopters set for these glasses

The eye relief is 3''. Depending on your shooting style you have a relitively full field of view between 2'' and 4''

I don't know. I think they recommend being within about 4 feet for maximum benefit. It is really very bright- too right for me once I had cataracts removed.

basically, the same size as the reading lens in a pair of bifocals. you can trim them if necessary

I think yes. I'm not positive because I haven't measured subject distances, but have gotten sharp focus at 3-5 cm.

The eye relief is short... about 3", so if your mount will work for that distance, that's fine. But, I've owned and returned FIVE of these' ALL of which had canted reticles. I personally can't tolerate canted reticles, so can't recommend this scope.

The maximum clip opening is about 9 mm (in the USA, that is 0.354 inch or a tiny bit more than 11/32 inch). You have to consider both the frame and the lens, whichever is thicker, because in most cases the clip actually contacts the top corner of the lens.

Anything closer than about 50-75 feet will be out of focus. Beyond that they are great. These are auto-focus and you can not adjust the focus manually.

Hello Kavanava,There are threads around the edge of the lens opening. They are 37mm in diameter. Rob

yes, but ... you need an 72mm wide angle, otherwise you get a black circle, since the lens is smaller than the one you need.
