- What you're trying to say is that an image is made up of a set of
- points (small regions of acuity), and your poor vision (due to
- myopia, the inability to focus properly, such that the virtual
- image is formed in front of the retina instead of on the retina)
- turns each point into a blob, covering more retinal receptors than
- it should, overlapping with blob-smear from adjacent points,
- creating a fuzzy image; and it is not possible to create an
- arrangement of points which is then made fuzzy by this myopia, such
- that this fuzzy image actuall forms some clear image on the
- retina.
-
- Is that what you're trying to say?
-
- Phase information isn't an issue.

- It's strictly a pixel problem; bandwidth isn't an issue.
- If Matisse (or was it Manet?) couldn't do it, we can't.
