Another left-eyed eyeglass wearer here.
My RF is limited to a Canonet, so I may not qualify for this poll in the eyes of some. I have mainly used this camera for travel, for which it has been perfect, but I have used it very little otherwise. Fortunately, I can see the whole frame with eyeglasses on.
Most of my cameras have plastic facings on the eyepieces, so I don't scratch my eyeglasses. In the case of cameras without such plastic facings, I apply a little bit of tape to the facing to protect my glasses.
I got an anglefinder to use with my 35mm SLRs on a tripod and it has an adjustable diopter built in. Though I haven't done much with it yet, I could adjust it for use with or without glasses. My vision is around 20/200, so I could scout an image, choose the composition, and focus with my glasses on. Then I could remove my glasses to more critically examine the whole frame and make final adjustments. I could even look up at the scene directly without my glasses on and see it well enough for purposes of checking basic layout. In practice, with careful eye placement, I can see the whole viewing screen of my SLRs, especially in the case of the older SR-T match-needle models with lower finder magnification, and I just leave my glasses on. This is especially true when using cameras handheld.
TLRs and waist-level finders (WLFs), which I use more and more, solve all my problems of wearing glasses and of left-eye dominance.
I have a LOT to say about being a left-eyed photographer, but I'll save that for another occasion.
