Maybe in ten years glass lenses will be all obsolete and a new era of optics started today.

@sonhouse

Interesting technically, but I don’t see the application for glasses for correcting astigmatism in humans. That would be like shooting ducks with laser-guided atom bombs. This technology is probably relevant only in industrial applications.

@moonbus
This tech is small enough to be incorporated in contacts, we are talking microns high stuff. I think smart phones will get them first, lighter, more light gathering power and so forth but telescopes could be built with industrial sized processes and of course we are not talking even 2025, more like 2028 or so but I think a revolution is starting.

Maybe even permanently installed, powered by the body and transmitting data like video and audio, temperature, Ph and the like via bluetooth or whatever pops up in the next ten years. By then it might go beyond UHF and into Terahertz territory. I just saw a terahertz amp pushing out some 30 DB of gain so that frequency band is getting closer to commercial applications.

Ok folks, here is MY internal data, blood flow, Ph, O2 stats, Glucose, the works, I made it into a video with music by Bruce Springsteen.

@divegeester
The optics are little micron sized posts that interact with light, they would be on the surface of the contacts which would be regular thickness and transparent.
The magic would happen by the exact placement and size of the posts.
