I'm 30, software engineer, and I have had glasses for most of my life. I have astigmatism from birth like a lot of people. Now, up until 25 years old, it was just that, and even hypermetropia. But suddenly from 25, it started to reverse, losing about 0.5 dioptric per year. It started super late, so I was concerned, but turns out there's no age to get myopia, it seems. Now I'm about -2.5 on each eyes. And it's irreversible. All the doctors told me to get up and look far, but they forgot to tell me to have as much sunlight as possible. Now it's my number 1 criteria for renting an apartment, because it seems to have a huge impact on limiting my myopia progress.

If someone has also an experience of late myopia, I would be curious to hear from it, e.g. I would like to know if it stops someday, and if there are good solutions for it.

You're at -2.5 thats nothing. I'm at -5.5 w/ Astigmatism and my prescription has mostly stopped changing in the last 5 years.

Get glasses and/or contacts and deal with it. You can't drive properly without correction, but 90% of daily activities are just fine.

I know it's nothing in itself, but the progress in a few year was significant, and my doctors told it to me. It was a huge dégradation in a matter of 5 years, while I was already old. I wondered what was the thing that started the bad progress. Maybe because I got a phone with unlimited internet and kept using it, maybe because of poor light in the offices (during my first job, despite being on the computer all the time, I had no sight loss, because the light was actually pretty good).

I think no matter what your correction is, you should take the steps to not make it worse, and I find that there's very little information about that. Even doctors just say "look far once in a while" which doesn't see so efficient.

So it got better and better, until it became myopia? Was there a point in the middle where you had normal vision?

hypermetropia and astigmatism stack on top of each other, with astigmatism it was always blurry, and then on top of this you get the hypermetropia or myopia. So, I never had a normal vision because of astigmatism, but if I didn't have it, I guess so ? But like anyone has a normal vision until they have myopia. What shocked me is that it developed so quick, after being grown up.

In an effort to share a Huberman podcast, I found a guy reacting (negatively) to it. And the critic was talking about something called “Active Focus”.

I’m going to leave this link [1] here for you to follow. Since I am just falling down this rabbit hole myself.

But if you do go down this rabbit hole, feel free to share info in this thread…I might also add my email in the bio. Anyways, good luck!

Seems like utter BS, regardless of all these interviews with those nobodies he is posting.

I don’t have time to go down a YouTube rabbit hole but in my experience it’s quite simple - you just have to do near-far-near focusing while outdoors. I read this on HN years ago right after getting my first indication that one eye was just barely no longer 20/20. I was always proud of my perfect vision and was quite worried. Since then I have tried to do several of those near-far-near transitions outdoors every morning and my vision is back to perfect in both eyes and has stayed there. Look at a finger, look at a tree far away, back to my finger. I would highly encourage anyone to start doing this regardless of current vision.
