Ask yourself, how much brighter is it outside than inside (assuming a sunny day vs a brightly lit office)? Before looking into this, I would have guessed 2X or 3X, but would you believe it's actually over 100X! I bet most people's guess would also be off by 1 or 2 orders of magnitude. Even outdoors in the shade, it is over 50X brighter than indoors. (For specific numbers and comparisons, see: https://www.ncbi.nlm.nih…

That's only correlation, light brightness has nothing to do with myopia. It's more likely from looking at things farther away from the face outside so that there is less light focused on the fovea.

It looks like the article doesn't have any details on how this works, anybody care to speculate on a potential mechanism here?

It doesn't work, this is terrible reporting.

There's an interesting paragraph in there: "myopic defocus is already in use in the US with a contact lens, “MiSight® 1 day” by CooperVision, which is U.S. Food and Drug Administration (FDA) approved to slow the progression of myopia. This product, which uses multifocal contact lens technology, passively stimulates the entire peripheral retina with light myopically defocused by the non-central power of the contact le…

They have you covered in other press releases:

It's nonsense. I was recommended this as a child - any improvement was temporary, and at best this will slow down the progression of myopia very slightly, in childhood. Nothing beats sunlight and outdoor activity in childhood for reducing myopia, but if you already have it as an adult - you're stuck with it.

Doesn't this article suggest there's some truth to strengthening the eye to improve Myopia, though? While the "new glasses" could of course be snake oil - assuming they're not for discussion would suggest that the muscles can be strengthened/corrected and all we're discussing is an implementation detail. That's assuming these glasses actually work in this fashion, though. .. and that they work, of course.

No, myopia is caused by eye length, not muscle structure. Eye length is determined by how your eye grows. The Bates method is quackery.

The "myopia is purely genetic" zeitgeist has been continually shoved down all of our throats in the west. Meanwhile, studies from Taiwan, Japan, and Korea show that myopia truly has an environmental component to it, e.g. childhood eyestrain and video games. It's also undeniable that myopia manifests more in middle class workers than working class, which indicates some sort of systematic environmental component. Since…

The currently favored theory is that it's due to a lack of UV light reaching the eye. It's not (just) video games, it's (also) school and generally being indoors instead of out at midday.

There's no such theory, and exposure to light brightness has nothing to do with myopia. Being outdoors causes less close up focus, which slows the progression of myopia.

More details from the Bloomberg PR: Kubota Glasses technology works to reduce the increase in axial length associated with myopia by projecting myopically-defocused virtual images generated using micro-LEDS on the peripheral visual field to actively stimulate the retina. Passive stimulation using myopic defocus is already in use in the US with a contact lens, “MiSight^® 1 day” by CooperVision, which is U.S. Food and…

Key words: "reduce the progression". Which means that marketing this as a cure is a complete fraud.

This will absolutely not, under any circumstances, "correct" myopia. You can only slow its progression, with techniques like: - Pupil dilating eye drops - Wearing corrective lenses as little as possible - Wearing glasses with fogged edges/rims - Reducing the time you hold objects close to your face The major factor behind all of this is to reduce the over focusing of light on your retina and fovea. The more light tha…

You so sure about that? My myopia has gone from -5.50 to -4.00 over the years.

Reads like snake oil to me. I'd love to learn how this devices reshapes your eye lens when not worn. There are methods out there that people swear by, but I haven't seen a drop of evidence. I'd jump at the opportunity if it worked.

If this worked I would take a loan if that's what it took. Most likely snake oil. Even more so since they are calling it "smart", I'm surprised there's no blockchain. Extraordinary claims require extraordinary evidence. This thing can somehow physically reshape the eyes (or the cornea at least) permanently, with no surgery.

Let's hope it doesn't pan out like it did for Nathan R. Johnson...

People who have the hobby of photography, might have some intuitive understanding of this brightness difference. If you are shooting with fixed aperture and ISO, your exposure times could easily go from 1/60 indoors to 1/3000 outdoors which is not quite a 100X difference, but close.
