Do you mean via some kind of therapy or intervention, or in general?

I had pretty severe myopia 30 years ago, bad enough that I needed glasses in order to legally drive. But it steadily has gotten better, without any treatment. I stopped needing glasses to drive about 15 years ago, and now I have nearly perfect vision.

EDIT: I searched around a bit and indeed it seems that the consensus is that myopia never natural improves with age. But...whatever was causing my poor distance eyesight in the 1980s slowly got better. DMV records (granted, not high precision data) demonstrate it. So I don't know what to say.

How old were you? Up to a certain age, your refractive power may change(in either direction). Doctors will often not perform LASIK until you have proven that your prescription has stabilized for a while.

My vision was at its worst when I was in my mid 20s. It's steadily improved since then.

My eye doctors have always told me that we get far-sighted as we age, so if you were near-sighted to begin with, then the aging process is correcting it. In another 20 years I would expect that you might start needing glasses again to drive.

I think whatever causes people with normal vision to become farsighted as they age also causes nearsighted people (or at least some of us) to become less nearsighted over time. It seems to be happening to me, though only slightly.

Is that EndMyopia / BackTo2020? I signed up for the "email intro" just to see what it's about, but it's really just a bunch of breathless testimonials and random references saying that you should wear slightly less strong glasses than your prescription.

He's basically trying to get people to pay $99 for a forum to talk about the same stuff.

The TL;DR for his program seems to be that glasses cause myopia to worsen, especially wearing distance glasses for close-up work. Might have something to it, but not $99 for.

There's a free facebook group with hundreds if not thousands of posts with vision improvement stories. No money needed. But vision improvement takes way more effort/time/motivation than the average person can muster.
