Can't find it right now, but there was a retweet by longevity scientist David Sinclair about a study in mice that exposure to UV-C could potentially reverse aging (and myopia) of the eyes.

I'll edit if I find the reference.

What I do is regularly go for a walk in the sun for up to half an hour without wearing glasses or contacts. If it doesn't work, I'll be getting a good dose of vitamin D in any case.

Having loved photography since an early age I have always been hyper observant about my own visual mechanics, and to preserve my 25/20 acuity.

At worst in my late teens my prescription was -1.25, at which point I started wearing glasses only for distance vision, never for reading and computer work. I am certain this diligent habit stopped the myopia progressing. Now that I’m 10 years out of uni my prescription has reversed to -0.25. I don’t wear distance glasses anymore and am careful with computer positioning to minimise eye strain. Hope my 25/20 lasts!

I can focus my eyes without glasses (20/15), and with glasses too. I can try on the glasses of a myopic person and still bring everything into focus, although it's an eye strain like I'm trying to focus on something 2 inches from my face. Astigmatism is tough though- either the horizontal is in focus, or the vertical, but not both at the same time. One aspect of this that I haven't heard anyone talk about is the fact…

> if you have bright enough light

This part isn't practice, it's the pupils contracting that improves the focus like looking through a pinhole does.

Do they ever perform lasik under general anesthesia? My eyes react so strongly to overstimulation like bright light or being touched that I couldn't even get the pre-tests done.

No you can't do that, because the patient must look at a target. There is an eye tracker in the laser but you have to look in the right direction. The surgery is much less impressive that you can imagine. Take an advice with a reputable, trained surgeon which will carefully look for any contraindication !

Theoretically, could you fix the eyeballs in place somehow?

I don't have a lot of myopia (max -1.5 on both eyes) but I also have astigmatism (around 1.75 for both). I find I can work fine on my computer distance-focus wise but the astigmatism means text are slightly blurry. Do any of you have this problem too? Do you have another set of glasses that are just correcting the astigmatism?

you can substitute spherical correction for astigmatism correction. the spherical equivalent is the normal spherical value plus 50% of the cylinder. so for -3.00 sphere -1.00 cylinder 100 axis, the spherical equivalent would be -3.50 sphere (blank cylinder, blank axis).

Why would you ever do that?

It makes your vision worse (because the astigmatism is really not corrected) and might trigger a myopia progression (because the glasses are too strong)

Thank you for the very interesting breakdown.

Regarding LASIK, I got my surgery in 2009, at 21 years of age. At the time I only did enough research to know to find a reputable surgeon in my area, and no more. Nowadays I would probably Google for more side effects and dangers. I'd likely hesitate at the risk of getting it so early and wonder if it'll be a waste as my eyes change, but at the time I just trusted what the doctor told me.

I still consider it to be one of the best things I've ever spent money on. I think the surgeon mentioned he over-corrected somehow, accounting for eyesight changes over the years. There's been some degradation. If I close one eye I can see that my right one is slightly less sharp and slower to focus than the left. But overall my eyesight is still excellent over ten years later, with none of the scary persistent complications I'd read about since the surgery.

Nowadays, I hear of newer methods of laser eye surgery that involve putting in lenses that you can replace with new ones when needed as opposed to resurfacing the eye itself. It makes me think about how much advancement there must be in the techniques since I'd gotten it done. If I'm still happy with my decade-old result, I imagine people getting it done today might find their procedures to be even better.

There is indeed much more evidence for this advice. This is my I do with my kids. Using your far vision a lot I childhood, with enough light exposure, could be a real preventive habit.

https://newsroom.uw.edu/news/glasses-stop-myopia-are-success... Their big breakthrough in understanding myopia occurred in 2008 when they studied a particular group of people who had a genetic form of myopia that’s very severe. They discovered a gene mutation that was causing the myopia. “It turns out it was a mutation in the cone photoreceptors,” said Jay Neitz. “We then realized that it’s really just the way that t…

Is the periphery not always blurry, because the glasses are only in front of the eye?

A randomized controlled trial in children found that undercorrection accelerated the progression of myopia. https://pubmed.ncbi.nlm.nih.gov/12445849/.

This trial had a similar but not statistically significant result: https://pubmed.ncbi.nlm.nih.gov/16907670/

(There are conflicting observational studies, but these two were controlled trials).

I got LASIK last year, after a lifetime of being basically legally blind without glasses. It was absolutely worth it and I regret nothing.

At what age did you get?

I only found a doctor that suggested LASIK now that I'm old (37), which I know is late for this, still I feel like doing it - even if to play with my kid without glasses for 10 years.
