...it's a *lens*. A rather obvious type, it seems to
me. Yes, lenses have all kinds of uses; this is just
putting a lens inside a carefully-created flat sheet.
I fail to see the significance over what we already
had, for instance how it can significantly improve
performance over presently available lenses in any of
the areas you mentioned. Could you explain what I am
failing to grasp, please?
