There's been plenty of human experiments by now even, check out the myopic defocus section https://wiki.reducedlens.org/wiki/Clinical_Studies https://wiki.reduc

  To clarify, none of the studies you linked to show reversal of myopia in humans. Some of them show a fast-acting (minutes to hours) effect of defocus on small axial length reduction. I don't know what is happening in the eye here (muscular?) but it's obviously not the physical reshaping of the eye's structure required to reverse myopia. The rest of the studies, like I've said, shown that myopia can be slowed, and maybe stopped, but there is no known way to reverse it. It's disgraceful that section is titled "Reversing Myopia". There is one important study linked in there that I haven't seen before, which I'm guessing the grandparent comment is referring to: https://pubmed.ncbi.nlm.nih.gov/23493295/ https://pubmed.ncbi.nlm.nih.gov/23493295/ Assuming this effect isn't the same as the irrelevant short term effect, maybe there's something here. This study is kind of weird as non-standard meta analysis where they didn't do the trials themselves. It's also important to call out that myopia happens primarily in youth, as the eye continuously grows to find focus. For most people this stops between 20-30 years old. The eye stops growing in response to over-focus. If there is a way to reverse myopia in humans (which there is still no evidence for, even with your link), then it may only be possible in youth, not adulthood, when the eye has stopped growing.
