"More to the point, is there some way to mathematically null out the eyeball
problem..."
I don't have a mathematical solution per se, but there is a simple practical
solution. I recommend the use of correcting glass plates in front of each
eye. These plates can be installed in a frame which might rest on the bridge of
the nose, perhaps with supporting frames wrapped around the head or at least
to he wearer's ears. You could grind your own glass plates, or possibly a
local optical shop could produce them for you. The supporting frame might be
made of metal wire or perhaps an attractive plastic. :->
You do have eyeglasses, don't you? Perhaps a Bauer-esque monocle?
