Thanks for asking about this and mentioning the curved surface of the eyes.
I've wondered about the same thing. I don't have any answer to provide but
can point to the likelihood that digital imaging could far more easily
accomplish the recording of an image on a concave surface. It would be easy
to map such an input to a flat representation. I doubt the phenomenon has
been explored as one would need the tool to do the exploring.

My hope for such a system is that it might provide a way for the optical
properties to be relatively free of distortions caused by normal lens
systems. It might be possible to actually converge two lenses on the
subject, assuming no background information, and get good stereo results
without the distortions ordinary optical systems create with converged
lenses. Just guessing...
