PRISMS AID BED READER (Jun, 1936)
This seems like it would just be really awkward and end up giving you a headache.
Actually, if you read the reviews on Amazon of people who actually used these glasses most seem pretty happy with them.

PRISMS AID BED READER
To make reading in bed easier, a British inventor has devised “lying-down” spectacles. Prisms mounted in eyeglass frames bend the light rays at right angles so that the wearer can lie flat and read a book held upright on his chest.




Actually, that would be really handy for anyone with arthritis in the neck.
I just tried this and the book was upside down. Not a problem if I turned it over but pretty confusing when I went to turn the page.
When my father-in-law passed away, I got his set of “TV-Specs”. They’re well made, easy to wear and great for watching TV while lying flat in bed. Easy on the neck.
I think this one I could use! The eye strain from traditional lenses. If you think about it, you lose 30% of your vertical viewing angle through the use of spectacles.
Glasses identical to these are still being made and sold by a half dozen companies. I wonder what vintage evac93rd has?
Here is a link to a pair.
