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.

Perhaps if they are given to children, it would result in them permanently developing 20/20 vision.

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

This is similar to the “active focus” method: https://endmyopia.org/ I’ve been in this Facebook group for a while and lots of people have great personal anecdata about their improvements. It’s really interesting to see a medical device come out and if they have clinical trials to back it up.

this method is absolute snake oil. Google around. Most myopia is axial in nature - in layman terms - your eyeball is just too long. No amount of exercises or staring into the sun is going to reduce its length.

Speed the slide = you notice

That's the interesting part to me. I have very very very slight glasses. If I never put them on, it's fine. If I've been wearing them, and THEN take them off, everything looks horrible. I mostly only wear reading glasses at work.

Happens to me when I switch between contacts and glasses despite the same prescription (well, not that everything looks horrible, but that I notice how accustomed I am to the peculiar way glasses shape the world for a few hours). I wouldn't attribute too much to it.

I read this as "We stuck a ring of LED's around some glasses based on some flimsy science. The glasses cost $0.50 to make, yet we can sell them for $10k a pair.".

I went pretty deep down this rabbit hole for a while. I've always been suspicious of eye doctors since every visit they find an excuse to bump you up a notch or two. Anecdotally, me and my brother had the same prescription in high school. I started refusing to go to the eye doctor. He kept going. I happened to see his contacts prescription maybe six years later. His prescription was now over a diopter stronger than m…

You know what else does irreparable harm? Failing classes because you can't see! Most people don't just decide that "hey, today is a good day for me to start wearing glasses, wouldn't it be cool!?" For young kids, it's usually when they start doing badly in classes or people notice they are squinting. For adults, it's having trouble with things like the DMV exam, caught by routine checkups, or when they notice their…

> That's all they are, they are not facts.

And that's why I said, "I think that will be borne out by research if anyone ever looks into it."

> You know what else does irreparable harm? Failing classes because you can't see!

And I am implying that I believe we are treating that problem sub-optimally and that I believe a better solution could be found for the majority of cases where myopia is an issue.

I read back through what I wrote and I believe I had a fairly measured tone with it. You disagree, that's fine. The whole point of "science" is that people are allowed to have contrary hypotheses and the data should be the final arbiter or who is correct.

How does this actually help treat nearsightedness when not wearing it? Does it change the shape of the eye ball?

No details in the article but I assume the "smart" part of the name implies it can adjust the image to adapt to different people. It's possible it has some kind of algorithm to slowly adjust the prescription over the 60 to 90 days so that your body begins to adjust by making eye muscles stronger. The visual equivalent of braces for your teeth. No real details, just speculation.

it's just a bunch of LED's in a ring. The 'smart' part is the person selling these...

> but do discuss with your doctor This requires having a doctor you trust. My experience with most doctors is that I can trust them about as far as a used car salesman.

Start by finding an eye doctor that doesn't have a glasses shop attached, imo. Or one that isn't "attached" to such a shop in a way they would profit from it, I guess. Without insulting any doctor in specific, my thought is that making a profit from glasses being sold is likely to impact how likely the doctor is to prescribe new glasses.

At my ophthalmologist office the glasses store is a different company than the ophthalmologist's office.

They might have a revenue sharing agreement, maybe, but they don't even encourage you to use it.

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…

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.

Not just the difference between indoor and outdoor light, but also the incredible variations between a sunny day in the summer and a cloudy day in winter. There's a pretty incredible difference.

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.

You can only see that far away if the light energy is that abundant.

Also sounds like the prescription is not too bad. Those of us with -5 and under do not really have a choice not to wear corrective lenses :)

It's fluctuated from -4.5 to -2.5 over the years. Currently on the better end I think, but I haven't been to an exam in a long while. I have friends with lower than -5 and from trying on their glasses, I would also wear them if my vision was that bad. Even at -4.5 the only major annoyances were street signs and confusing people from far away though.

Go to an eye doctor.
