Eye relief. Should I always extend it when not using glasses?

It's daft but I cannot tell what is best. I know if I have it fully screwed in, I have to hold the binoculars away from my eyes to avoid vignettes.

But if I fully extend it (screwed out) while I can see without vignetting, it feels like the circular field or view is reduced? Is this possible or am I imaging it?

I feel like at this stage I should just wind them in and hold them far away from my face as it's easier to adjust, but I don't know if that's the proper solution or not.

How do you cope with glasses being smudged by the adjustable eye relief?

Maybe I'm paranoid but whenever I've used my binoculars with my glasses, I see the smudges of the eye relief on my glasses. So far it's easily removed with a microfiber cloth, but I am concerned it will just take one piece of dirt or grit to get trapped between the two and my expensive glasses will be ruined. Are there any kind of aftermarket soft covers I can add to my bins, or is this just the risk of using binoculars with glasses?

I've got some bins with good eye relief. But whenever I go to use them with my glasses on, it takes me three or more tries to get the binoculars in the right position without bumping the frames.

Does everyone have this issue and does it get easier with time, or is it just part of the issues of wearing glasses with binoculars?

Debating trying to make a neck strap that has a carabiner attachment to then quickly clip my binoculars to them when needed and unclip for use, but wondering if it's a bad idea - the fact I can't find anyone online who has done similar suggests it's foolish, but I'd love to know if anyone has tried it before and how they did it. My current plan was to somehow tie two straps to the bins, then attach them to a keyring loop - but just trying to figure out how to securely connect the strap to the bins without it going via a buckle

Surely that's impossible to focus on anything over a set distance, yet I see many bins listed as focusing from 5 metres to infinity. What is infinity in this context?

Trying to get some use out of a pair of Carson RD 825 binoculars. I've adjusted the dioptre but find I can't get a reliable focus across the range of the focus wheel. The close focus is rated at 4 metres, but I seem to only get it to focus at roughly 6 metres. Everything else across the focus wheel seems to be put of focus, no matter how I adjust the focus wheel for the chosen object.

Is it just a chance the prisms are knackered, or is there an easy way to resolve the focus being out? I hoped collimation, but I gather that's only really for resolving double vision.

They were sold as only having a broken strap mount. Obviously my fault for trusting to buy online. When I got them, I found the dioptre adjuster was gummed up and snapped. Probably glue and grease.

The right bin also rattles. From what I can tell it still looks clear, but waiting to try and reglue it before confirming.

I'm of course going to try and get my money back - but if I can't, how easy might it be to make it into a monocular for the one working side? Simply cut the two lens apart and try to it either a fixed monocular, or get the dioptre repaired so that one lens works as a monocular?

Shame on me really. Was a pair of Carson 8x26. Too good to be true.

My new bins didn't come with either rain guard or objective lens covers. Debating buying some aftermarket ones to fit, but ok just wondering how often do you use them and have they ever saved your binoculars from damage?

Been trying out my new binoculars today and they're great. But I've found with the eye cups adjusted so I can see the full view, I still end up resting them in my upper eye socket/brow. This has led to some slight pain.

Are you just meant to hold them in front of your face hovering freely, not touching? Or are you meant to gently stabilise them against your brow/eye socket?
