Canon is Making Metalenses, Further Legitimizing the Technology (petapixel.com)

Metalenses are a relatively fringe optical technology — at least, they were. Until now, it has been largely pursued by startups and scientists but that is changing as Canon has jumped into the fray and not only makes them but also produces the equipment necessary to manufacture them.

The goal of a metalens would be to, eventually, wholly eliminate the smartphone camera bump.

They'll do anything to avoid giving us a slightly thicker battery...

Fuck smartphones, I wanna finally have glasses that are thin, light, and without distortions, reflections, or chromatic aberration

And have a bigger sweet spot.

Same for VR headset optics.

Is this currently limited by lens diameter? It seems it would be - so huge glasses would be more forgiving in this sense?

Mainly it's number of lenses.
High quality camera lenses have like 10-20 lenses, while glasses have ... 1
