My dad was an M.D. and in the mid 50's I recall he had a pair
of "prism glasses" which were designed for people (probably who due
to polio) could not sit up in bed to watch the new-fangled thing called
TV, or to read a book (more likely just TV, now that I think about it).
They were right angle prisms over both eyes which gave sort of a 
periscope view, but in stereo. I recall they color fringed rather badly
(on black and white tv), but they did work after a fashion. Presumably
something similar could be cut today which would give a slightly
vertically displaced view at a given distance - or alternately I'm *supposing*
that regular glasses could be cut with a prism to give vertical displacement.
I have a pair that was cut to allow viewing Holmes format cards at a distance
of about 14" using horizontal prisms (plus they incorporated my normal
eyeglass correction as well). The only problem with them is that they focus
so close, you can't see the table very well to pick up the cards!
