IXI's autofocusing lenses are almost ready to replace multifocal glasses

> It still needs to obtain the necessary medical certifications in order to sell its glasses and get all the production pieces in place

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.

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.

> the technology [...] can be separated into two parts. First [...]

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:

> [the] prototype lenses, made up of layers of liquid crystal and a transparent ITO (indium tin oxide) conductive layer. This combination is still incredibly thin, and it was amazing to watch the layers switch almost instantly into a prescription lens

Important to note, of course, that this only works for people with normal binocular vision -- but that's the majority of customers.

Buying lenses is often the most expensive part, especially for those with astigmatism, second only to the frames themselves, which is another racket altogether.

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).

(I'm aware of the multifocal glasses mentioned in the article; they didn't work well for me.)

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

So the finish company's eyeglasses didn't fit a "British" face?

Fun story about this problem. When I was a kid I was a nationally-ranked swimmer. Almost everyone who could wore "Swedish" racing goggles aka swedes. These are very simple and tiny goggles, just a plastic cup that fits on, almost within, your eye socket. Your eyebrow normally sits over the top of the goggle, holding it onto your face. (I could swim slowly without the strap.) They are amazing, by far the best racing goggles out there. No foam to peal. Small enough not to fall off during a dive. And held together with string so you can adjust them perfectly to your face. They were also dirt cheap. But without any soft parts they are unforgiving to the point of racism. If your skull is even a slightly different shape than the Nordic/Viking/Swedish ideal, the goggles will not sit on your eye socket properly. On Asian people they tend to leak unless you tighten them painfully. On many black people they tend to rotate and climb into the eye socket. To nobody's surprise, they have kept the "Swedish" name because, in this case, any racial connotation is very appropriate.

(If you buy these, ditch the stock straps. Nobody uses them because they rot/age very quickly. Use silicon string.)
