NL 8x42 eye relief for those with glasses (1 Viewer)

Must?
Like you I can wear contacts when I'm out hiking or similar, but I can't bring myself to spend that kind of money if I can't use my glasses with them.
Me and my wife both have 8.5 x 42 ELs and have no problem with wearing glasses for short-sightedness. We tried 8 x 42 NL Pures for three to four hours at a reserve and their optics day. Company was great leaving the bins with us in a hide for that long. Had no problem with wearing glasses with these as well. Great field of view and could see right to the edges of the view. Also tried the 10 x 42s and had no problem.
Thanks very much, I think I'm going to try the NLs.
You won't be sorry! ;-)
Just wanted to update the thread, I did in fact get a pail of NL 8x42's and found that there was no issue with eye relief and my glasses. In fact, I had to turn the eye cups out one step to prevent back outs so there is room to spare.
For anyone in the future looking at this thread for reference, I'm a -9 with astigmatism, Nikon lens to keep them thinner, and my measurements on the NL 8x42 had a physical distance from the ocular lens to the top of the eye cup at 2.2 mm when fully retracted so nearly 16mm of usable eye relief based on Swarovski's numbers (I didn't actually measure the true eye relief so I'm assuming the 18mm stated). In sort, should be no problem for eye glass wearers even if the prescription is strong.
Thanks to everyone who offered their insight and experiences when I initially asked the question.

I own and use both an EL 1042 and NL 832. I wear glasses. There is a difference. The ELs eye relief is longer. I have no problem getting onto birds with NL and glasses in place. I do though see more field of view when viewing without glasses through it. They are awesome enough in every other way, that I accept this.
Yes the longer eye relief for the ELs is what had them as my first choice but the very low lip on the eye cup makes the NLs work for me so both should be good for eye glasses.
Seems a really good guess that "lower lip" on the NL eye cup was a thing Swaro had to do to achieve the stated eye relief after changing a few things optically from EL to NL. One issue FYI, no one has mentioned, but can be reported after couple years of frequent use, the NL ocular lens gets mucked up faster than the EL, (and other binos, I have) requiring more frequent cleaning. A non issue for me, but a thing to know about.
EL is actually bit shorter then 20mm
Leica NV gives more real ER with 19mm ER then 20mm of EL.
Still, EL is easier to see with glasses then NL becasue of it's much smaller FOV. but NL is just fine with glasses.
I have never experienced or heard some getting trouble of NL's ER.
as similar issue of ER, SRBC, which declares to have same 18mm with NL, appears to be 1.5~2mm shorter. and eyecup depth is almost Identical.
also. real ER feel same with 13mm spec Leica UVHD+ 8x32 and 19.3mm spec shuntu panorama ED
Specs doesn't always tells the truth.

I can only repeat that the NL could cause problems for some glasses wearers in the lowest setting, especially for long-sighted glasses wearers with clearly convex lenses, where the distance to the metal edges is not sufficient and you could get nasty scratches.
IMO, the NL are therefore not entirely suitable for glasses wearers.

Andreas, believe this pic kinda shows what youre concerned about. Indeed the metal inner ring surrounded on its circumference by the outer but slightly higher rubber of the eyecups is close. I had the concern early on, posted to that effect here, (but cant find my post). It has not proven to be an issue in my case. Whether the eyeglass lens touches that metal ring depends on couple things. A prescription causing outward curve of the eyeglass lens might, maybe, could, sorta. But in my case at least, the curve seems to span, cross from rubber to bino lens and just misses the metal ring. The eyeglass frame also effects things, rimless frames being an obvious example. Most frames add to the spacing, prevent the EG lens from reaching all the way to the metal ring or even the bino lens surface. I get the concern, but this seems a worry that not many will encounter. Like many posts here, buyer should try first. That sorta covers it - no?

Hello Tom,
My concerned are not unfounded; I have the binoculars myself and cannot use them in the lowest locking position.
In addition, it is an open "secret", from minute 3.15
Andreas
Dont believe I said it was. Doesn't the pic illustrate the potential for concern? Im an N of 1, as with eyecups screwed all the way down so far its not an issue FOR ME. It may be for you. But for how many? Try before you buy suffices.
