"Cameraless eye tracking" is understating the key insight here. They don't even need to track which direction you're looking! The only thing they need to measure is the difference between the two directions, and parallax tells them how to focus.
Important to note, of course, that this only works for people with normal binocular vision -- but that's the majority of customers.
Looks super cool!

Oh, ok. I hope they have enough funding to last till the FDA clears them, in 2030 :/
The same organization which allows any snake oil to be marketed as long as they say it’s a “supplement” will hold a pair of glasses up for years, as though there could be a hidden danger to a lens that can change to a second prescription.
I am not so sure about the eye tracking and autofocus stuff, but would love a simple focus knob on the frames to adjust instead of changing to a different pair of glasses. I suspect the tracking and focusing electronics must be somewhat clumsy and a battery life of a single day sounds suboptimal for me.
I'm under 40, recently had cataract surgery to address mild cararacts, and deeply regret that choice. I strongly feel I lost more than I gained, and now need to carry multiple pairs of glasses every time I go out to engage many common activities.
Unfortunately I don't have presbyopia at all (my surgery still left me myopic) and my inability to change focus distance is drastically more severe than what happens naturally with aging. This first generation of IXI glasses won't be useful to me.
But I really, really want something like it.
Putting two adaptive dynamic systems next to each other is tricky. Your eyes and these glasses could easily create a positive or negative feedback loop or begin oscillating. So while cool I hope they have some experienced controls people on staff to detect and prevent such things.
In the last two to three years, I've hit a point where I need to take off my glasses (near-sighted, can't see things far away) to read my phone. I can still make out the text with them on, but it's physically uncomfortable and holding it at a distance helps.
I've been thinking about the existence of bifocals and how they aren't ideal as I come to terms with the inconvenience of removing my glasses and putting them back on repeatedly as I task switch. This sounds pretty great and I hope it's not smoke and mirrors (given enough time, science fiction tends to become reality, so I'm hopeful).
Honestly, even if they could shift focus via some sort of "command" - a muscle tick or something - that would be a game changer as it is. Every time I play D&D, I have to keep taking off and putting on my glasses so I can read my notes, and see my players' faces clearly.
(I'm aware of the multifocal glasses mentioned in the article; they didn't work well for me.)
As a glasses wearer I'm looking forward to this tech. I like the idea of natural, seamless auto focusing, and as a future fantasy, a simple, toggleable overlay of info would be nifty.
Going out foraging and being able to identify plants and fungi by simply resting my vision on something for a pause is the sci Fi tech I actually want
I wonder how long the wait will be for AR glasses to have this option too.
It's only me or it does not explain how it works?

is the part that tracks eye movements and what they are focusing on.
The second part is never written. There is a hint later on:
