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.

I've fixed my myopia from -4.25 to -3.25 over the last 5 years (I'm 32). The secret method optometrists don't want you to know, is that I've been staring at a screen just as much and just the same as I've always done.

My point is for some people it can fix itself naturally, so unless studies are double blind, anecdotal claims should be taken with a grain of salt.

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.

Vision guides the growth of the eye: if spectacle lenses cause images to fall either behind or in front of the retina (hyperopia or myopia, respectively), eye growth compensates for the optical effects of the lenses

snap.

dame paper, different links.

The eyeball is not “just” too long. It elongates as a response to the stimuli from the lens projecting an image at a focal length behind the retina. Most kids are not born nearsighted. It develops over time. This is how.

So, they eye works pretty much like a camera - but it's not a camera: it's a complex dynamic self-assembling, self-tuning adaptive structure.

The fact that it's geometry is roughly static around a focal length that has sharp focus on the retina is a wonder of homeostasis with at least three known tuning loops:

1) the lens Moving on swiftly...

2) a slower feedback loop adjusting the choriod (hence focal length) in the order of hours.

3) an even slower loop adjusting the eye geometry over longer periods of time.
