Now and then someone out there has a bright idea that a personRay said:Software would not work. There is a simple solution. Have
appropriate lenses implanted in your eye balls. I had it done. I am
71 and rarely have to wear eye glasses any more. It is called
cataract surgery.
Ray
might not have heard of.
For example, a couple of bright guys figured out a way to build a
camera that "captures the light field."

What this allows the user to do is focus the image a week after
they have taken the picture or to focus on different parts of the
image, all after the picture has been taken. And focus seems to
be what the original poster might be looking for. The camera is
supposed to be available for sale as soon as they get
manufacturing going, and might be now.
And there are things like Fourier transforms that relate the pixels
on opposite sides of a lens. A conventional monitor today might
not have the resolution needed.
But they are claiming holographic resolution monitors will be
available soon.

Suppose you could reproduce "the light field" or a hologram on
demand. Could that do exactly what the original poster was
asking for? Perhaps we need some math describing the optics to
to be able to answer this question.
Now a question for all you folks buying "reading glasses" (glasses
for the far sighted) for a few dollars a pair. Has anyone found a
source for reading glasses for the near sighted for a few dollars a
pair? All I have found in the stores are positive lenses (for the
far sighted) and have been searching for an identical display for
the near sighted. I sent emails to a couple of the companies that
have displays in the stores asking, but didn't get a reply.
Thanks for any tips.
