Getting my cataracts done made the most difference but putting a 1+ diopter lens in the viewfinders of both my Nikkormat FTn and my Bessa R3A also helped greatly and pretty well overcame the issue of wearing glasses while using either camera. I'd had to stop using the SLR until my eyes were fixed as I couldn't get clear focus.
As for the "other", nicely put. :-) However, as a practicing atheist I don't think I'll burden the forum members with my thoughts, even if others choose to do so. The real issue might be contained in part of your reply - "adding value" ???????
