New "Scratched Glasses" Give Perfect Vision

My wife already wears contact lenses using that concept. Not exactly new. She likes them. I prefer the visual acuity from a single prescription contact lens and just wear readers when I need to see up close.

You can even get replacements for your own lenses with ones with concentric rings with different focal length:-

How the brain figures out which image to look at is a mystery to me.

But these glasses seem to have lots of little lenses, so, to me it's even more surprising that they work.

There are also IntraOcular lenses on the market using this system. There is some loss of contrast in the image due to the defocused light from the many different zones, but the eye/brain system is very good at sorting this out, at least for some people.
