Does anyone have actual experience reversing myopia? During the pandemic my eye sight worsened pretty quickly and I have glasses for the first time ever (presumably the worsening was already there but accelerated by being on my computer more during lockdown, working longer hours, getting out of the house less).

My prescription is really slight (I think like -.5 or -.75) and I was really curious if this was reversible at all, but I'm skeptical of claims that it is.

I did, but I was going when I did so. Spent more time outdoor looking far, then close, then far, etc. I've become aware of the duration of the transition in focus and it now serves as a warning side. Whenever it seems to take longer to focus on far-away things I know I need to do some more exercice. Went from needing glasses (which I declined) and seeing everything blurry to having a great vision I can't complain about.

Weirdly, if you're over 40 and have been reading for a while and then look up and notice everything looks blurry in the distance, you can tighten up every muscle in your body for about ten seconds and when you relax much of your distance vision will be recovered. Let's call in the poor man's reversal.

I would advise getting your blood sugar levels checked, high blood sugar has a negative effect on eyesight, and given that during pandemic many people have cut exercise and may have started snacking more. There is a strong correlation between type 2 diabetes and vision problems.

This is sound advice, our ophthalmologist said the same: glucose level can change the thickness of your cornea (https://pubmed.ncbi.nlm.nih.gov/17964654/), and that can even improve your vision. A sudden change in vision, for the worse or better, merits checking your glucose level.

You are not alone[1].

Not me but I have heard from multiple independent contacts telling me that they reversed slight myopia through yoga at different period of time. And every time I hear that I try to search for scientific evidence and come back empty handed.
