This Contact Lens Puts a Display Right On Your Eye

This Contact Lens Puts a Display Right On Your Eye, article.

OK, this I don't get. 'Cuz the eye can't focus on its own surface. Hold text a foot from your eye, you can probably read it. Hold it a couple inches from your eye, you probably can't. Hold it a millimetre from your eye, and you really can't read it.

One solution would be if there were a super-tiny projector to actually project onto the retina with micro-laser beams (somehow taking the light-bending of the lens into consideration). But such compact technology is at least a couple decades away, I'd think.

Just add a layer of microlenses acting as "reading glasses" (actually "pushing" the image of the display away from the eye).

Hmmm, perhaps. I guess it would be tricky to focus them all in unison, or rather to assemble their many different images into one perfect image, edge to edge.
