I also have to remove my glasses to use binos, or at least to use them effectively. My problem is that even with the eye cups of most binos screwed all the way in, the lenses of my glasses will hit the lens of the binos before I can get my eyes close enough to the binos for the correct eye relief. If it's just a quick glance through the binos freehand I can make do, but I end up just taking my glasses off to glass from the tripod for long periods of time. It's a hassle, but it's the only way I've been able to glass comfortably. As others mentioned I've been able to adjust my binos to see perfectly without my glasses.
