I have wondered this many times, for the reasons you set out above.What if folks reporting they see it, are actually peering through their own deteriorating natural human lens AND don't know it?

I can think of two possible reasons:
1. Differences between the anatomy of different people. ……..
2. Differences in how people's brain processes the image. ……..
Wild theories with no objective proof, of course. However, there must be some reason why people don't "see" glare - and others do. It can't all be wishful thinking on the part of those who just paid a lot of money for the latest "state of the art optics".
……..
I believe, in my #180, I am alluding to your #3 above. I fear this is a real problem of... Birdforum.I can think of a third one, bit this is now a provocation, the entire Birdforum will hate me after this, and I may even be banned from further posting:
3. More or less experience how to use binoculars.
Okay, since Henry and Holger Merlitz are among those who report seeing glare, I have to immediately withdraw this third reason as totally unrealistic (it was on my mind, and so I just had to say it once
😝).
In fact, I think the reason no 1. mentioned by Hermann is a very plausible one, and so is the difference in holding and positioning binoculars - if you are used to using Ultravids all the time and suddenly switch to a Swaro, you may in fact have to adjust your viewing position a bit - that‘s at least my experience.

You're right. I once bought a Ferrari but still had to adjust the seat to find the best driving position by myself. Not to mention learn how to get most out of it."This happens when I do that, and I paid so much money that I have a right to perfection at first look.
Fiddling with IPD, eyecup extension, and how I seat them into my eye sockets has fixed all of the initial "problems" which were not really problems, just idiosyncrasies of a new binocular.
Henry,Hi Canip,
I agree with Tom that yours, Holger's and my position on the NL glare are more similar than you think.
We've all reported being able to see it (I've only tried the 8x42) and we can all largely neutralize it with the right IPD and eyecup settings. I also agree with you that having experience with handling and adjusting binoculars is helpful in finding the most glare free positions for the eyecups and the IPD.
It took some time for me to find the very best IPD setting and eyecup length, which for my face falls between two click stops - one millimeter too long and I see more glare than I want to see, a fraction of a millimeter too short and I begin to experience blackouts. At that narrow sweet spot of eyecup length the view is quite relaxed and virtually glare free. Still, I can't say I wouldn't prefer to see better baffling that would block the glare over a wider range of eyecup settings.

Is EDG, SF, NL and EL, yes?
Be happy with your EL, they are a fine glass, and you will never run out of things they will show you that you didn't even know were there.I wanted to compare them to my ELs, I might have had or made the opportunity to compare them, but honestly I can't afford them. I'm still interested though (sighs sadly).
You are right of course. Better to enjoy what you have and see what you can see. Some times chewing over equipment (bins) reading magazines and forums are just substitute activities.Be happy with your EL, they are a fine glass, and you will never run out of things they will show you that you didn't even know were there.
They will probably outlast you, and if anything goes wrong Swarovsky will fix it.
With the CL 10x30 it took me several hours until I had found the best IPD setting and eyecup length to minimize glare. Longer than with any other binocular I've handled over the past 40+years. I'm still not entirely happy though. There are other binoculars that handle glare a heck of a lot better.It took some time for me to find the very best IPD setting and eyecup length, which for my face falls between two click stops - one millimeter too long and I see more glare than I want to see, a fraction of a millimeter too short and I begin to experience blackouts.

You can say that again.Still, I can't say I wouldn't prefer to see better baffling that would block the glare over a wider range of eyecup settings.
"I put the binoculars behind my eyes" ----That might explain why you don't see any glare; sorry, I couldn't help it. Now, seriously, in a nutshell: you're not doing anything special.It will not have escaped the reader of this forum, that I have reported repeatedly, that I never experienced glare with the Swarovski EL 8x32and the NL pure 8x32 (and 8x42).
Therefore it may be helpful to report how I use and have used these binoculars. I turn the eyecups always fully out (I wear no spectacles or contactlenses, so naked eyes), put the binoculars behind my eyes and the images are there, no glare, no reflections in the optical train etc.
That is not only so with the Swarovski binoculars I have used but also with the Leitz-Leica and Zeiss binoculars I have used.
