Wow, this is the first Hacker News post I've seen where someone actually understands myopia, emmetropization, and peripheral defocus. Every other post on myopia is filled with people guessing their own random nonsense about Bates, wearing underpowered lenses, and outdoor light. Completely unifnored. I also had no idea about the relative blur of different color wavelengths. I wonder if that's related to the possible "toxic" effect of blue LED light on the macula.

I've installed your Chrome extension and I'm eager to learn more. It's too late for my vision, but it's still getting worse for me in middle age, so I'm very interested in the state of the art based in real science.

Congrats! For anyone who's interested, there's a group of us dedicated to natural myopia reduction at reducedlens.org, which is a free and open-source fork of endmyopia. I've even started measuring my axial length to try and get better data on if this stuff actually works (only one measurement so far though, so nothing interesting yet). The nature paper was pretty crazy. Basically because blue bends more than red (th…

ReducedLens is absolute quackery! This is why I hate myopia discussions. Myopia is not reversible, if you think it is, you don't understand what axial elongation actually means.

You might be interested in endmyopia.org Its about controlled axial length changes to the eyeball with differing methods.

What mechanism causes TMP activation / ECM breakdown to cause eye reshaping required to reverse axial elongation? There are no known mechanisms of this, so any claim of reversing or "ending" myopia don't have any basis.

How do minor correction improvements anecdotally reported track choroidal thickness? Oh, they don't?

Btw the Chrome plugin could use an on/off option in the context menu to help with quick comparisons.

I don't know what that means - All I have are my own anecdotes and others.

I personally went from -3.0 diopters to almost 20/20 vision. So either I'm experiencing a fabulous placebo or the 'known mechanisms' aren't as comprehensive as we've been led to believe.

Sorry, but I know EndMopia believers don't know what the choroid is. Science knowledge is terrible in this space.

An arbitrary "correction" of two diopters is within the margin of error of the possibility of initial overcorrection, choroid changes, inherent small variability in eye tests, and tricking yourself into believing your vision is better than it is. -3 is trivially myopic, but if you do manage a 4 diopter change, verified by an ophthalmologist, not an optometrist, then you would be a medical miracle and worthy of multiple case studies. Get on it if that's the case!

This is very cool and exciting. It seems like a good method to reduce the development of myopia. However, my understanding is that myopia is also simply age related. Discussions I've had recently were looking at the hardening of the lens as a factor. I've been trying to re-train my eye with an eye chart, and I've been surprised how after just a few weeks, my vision has gotten much clearer. Going from 20/40 to nearly…

Could you describe a bit more about how you've re-trained your eyes with an eye chart?
