Earlier quoted context omitted.

Add to that the blinking LEDs that track eye movements. No thanks.

Are you one of the few people who are able to perceive infrared light?

No. My wife has migraines, though, triggered by flashing lights. I’d have to wonder about the long term affects from the glasses.

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.

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.

If only they’d had a frontend web dev on the team!

Don't say that, I don't want lenses running on Vue/React.

Make it love2d where humans and building are replaced by pixel art.

The FDA doesn’t “allow” snake-oil supplements. They have no authority over supplements.

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 natural…

I don't have cataracts, but my prescription is so severe and I'm getting to an age where there's an RX difference between near, medium, and far sight, and I just wanted to commiserate. It is annoying to have to have multiple pairs of glasses, and remember where you put them, and do you have the right ones for this, etc.

There is potential danger with a lens that can suddenly change to a second prescription. For example: imagine you're driving and your whole field of vision suddenly starts flickering in and out of focus. That would be incredibly distracting and pretty dangerous. Even if they just started focusing on 1 foot away it'd be quite bad.

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.

This exists. There was a frame with a slider on the nose bridge which refocuses circular lenses. I read about it a long (decade+?) time ago.

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.)

An alternative to multifocals is glasses with one lens for near and the other for far or to use a contact lens in only one eye in addition to your normal glasses. This also obviously comes with downsides that take some getting used to but some people prefer it.

They in fact do have a lot of requirements for supplements and their labeling, but do not require (in fact forbid) any claims that the supplements should be used to treat or cure any disease.

How does it compare to multifocal contact lenses?

My understanding of those is that contact lenses work the same way that multifocal glasses work, with the added disadvantage that every time you blink, it takes them a second to re-align correctly. So this should be completely different, if it works.

I tried them and could not get used to them. I went back to using single focus lenses and using mild readers (1.00 or 1.25 for desktop screen work at arm's length, and slightly stronger readers (2.00 or maybe 2.50) for very close work.

I typically have a pair of mild readers that I leave on the desk and carry a pair of the stronger ones around for reading my phone, restaurant menus, etc.

Note if you wear glasses you can "focus" them to some extent by sliding them up and down your nose.
