Apple buys startup focused on lenses for AR glasses

Consider foveation as well — only a small part of that is truly in “focus”.

Some up and coming be glasses take this into account and expend lesser resources on the part that’s outside the important part (they don’t render that part in a high resolution, so it’s left blurry, which is actually how our eyes work anyway)

Out of interest, what's the FOV for people who normally wear glasses?

Do you have a source for that? Their website says it has a FOV of 35° x 20°.

I'm not saying that it's not worth it - just that we have a lot more to do than a single acquisition.

Two of those three are entirely doable (and have been done) - the main problems with them are 1) economy, and 2) that, while cool for individual, they'd be absolutely disastrous if ubiquitous. You don't want everyone to get themselves a jet pack or flying car, not unless 99.9% of flying is done by a foolproof AI.

Put your fingers in front of your face, in the middle of each eye. The glasses would only display the overlay between your fingers. The other half of your vision (and it is a hard cut off as you move your head) does not get the overlay. That would be roughly 90 degrees, which puts 60 and 30 in perspective.

Say we have 1,000 pixels. With current lenses we can display 500 of those pixels over 30 degrees of vision. This is the tradeoff between FOV and Resolution. You could also display those 500 pixels over 60 degrees of vision at half the resolution. A better lens increases the maximum resolution, so you can show 500 pixels over 15 degrees of vision. But you're still going to bottleneck on the total number of pixels you can display. And if you're targetting FOV having higher resolution only hurts because it costs more of your total pixel budget for less of the users vision being full.
