Lee,
If you wear glasses while using the new CL 8x30B you won't be able to take advantage of this "optical box" when you use it. With the eye cups in the closed position your eye glasses determine the position where your eyes are placed. I think that Vespobuteo does not like the design of the eye cups because they keep his glasses too far away from the oculars.
If the eye cups had intermediate locking positions one might be able to adjust the eye placement somewhat but not as efficiently as people who do not wear eye glasses can using the "optical box."

Bob, shouldn't one's eyes arrive at +/- the same place (ie the EP position) whether your naked eyes are simply positioned by the extended eyecups or this extension being achieved by virtue of spectacles resting on the closed eyecups? I imagine the light box to be a beam light as wide as the exit pupil and a moderate length of this (the box) being where your eyes are delivered, irrespective of wearing or not wearing glasses. This being so, isn't the light box supposed to allow greater lee-way in positioning whether you do or don't wear spectacles?
