Earlier quoted context omitted.

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)

It's the normal thing to do if only spherical lenses are available. E.g. cheaper off the shelf contact lenses. Contacts with cylinder correction are relatively novel and have downsides. The lenses are not "too strong", astigmatism causes two focal points, and the spherical equivalent puts you in the middle of these two.

It has been studied that myopia progression can be almost stopped via daily administration of Berberine. However i have learnt this fact when it was too late for me and I have failed to find a pharmacological reversal. Although retinalamin might have some potential. It would be interesting to see wether Berberine potentiate the presented method. Although i have been without glasses for a whole year and I was nearly b…

What is the mechanism of this? Can you link sources?

It's Bilberry, not Berberine, I always confuse the two.. Here's the study. I have no idea wether the mechanism is from a classical antioxidant/anti-inflammatory/senolytic/pro autophagic mechanism or if bilberry has a unique action mechanism. The field is so underfunded I expect most regular protectors (e.g. Skq1) to have similar or greater effects but i can't be certain.

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…

This sounds you like have hyperopia. This thing you call "focus" is in part accommodation, another part is probably mental concentration. This accommodation ability deteriorates when you are older and develop presbyopia. See https://en.wikipedia.org/wiki/Accommodation_(eye)

What my sibling said too: brightness will lead to sharper vision due to the pin-hole effect.

Bilberry prevents myopia progression. Also, how do you diagnose IOP? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6296196/

> Berberine prevents myopia progression Any sources about that?

I edited ly comment, it's not Berberine it's Bilberry https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6296196/

Ophthalmologist here. The myopia epidemic is real thing. The advice given in this post is not a dangerous thing to try. However, I doubt that the theory is true, and I doubt that following this method will really help myopic patients. Let's try to justify this point : "The long-term use of over-correcting glasses induces myopia" This is quite true. But it induces a myopia which is reversible. Overcorrection (which we…

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.

As far as I understand it, David Sinclair lost all credibility when he was invited to debate scientists in real life and refuse. The rate at which he spins up companies is also a bit alarming. This is as someone who would love for what he is preaching to turn out to be true.

There's also interesting theories about bright light exposure preventing myopia in children. Send your kids outside at recess every day :)

I got myopia during an age where I was exposed to very bright light everyday. Playing cricket everyday under scorching hot southern India summers didn't help prevent it.

I have had myopia since age 18 and it constantly worsened. I got diagnosed with glaucoma in my 30s as a result of high IOP, but only because I started to have bad vision because my right optic nerve is already damaged. I started taking medication to reduce IOP then (a few years ago) and since then my myopia stopped worsening. I have this image of my eyeball in my head, being basically a skin sack full of water enclos…

There are devices to measure IOP, most used but kind of inaccurate with a small „air burst“ on your eye. There seem to be more accurate measurement methods but they involve „touching“ the eye.

I have been working on doing this since the start of 2020. I purchased glasses for almost all the diopters from .5 to -4.25 (where I started) cheaply on Zenni, by going with minimal add-ons, it makes the total cost per glasses pair between $10 and $30 each. I have customized text on each of the frames that says their correction, since some of my frames are duplicates with different lenses. I am down to about -2.75 so…

I can attest that I’ve gone from -5.75 to -5.00. And I’ve stopped what felt like an inevitable worsening of my vision. Anecdotally people have reported you can improve at about 0.75 diopters per year and that resonates with my experiences. Also anecdotally, people who spend a lot of times outdoors seem to recover faster.

I move my screen back and don't wear glasses during work. I also have an eye chart hanging in front of me across the room. I stuck to near-far focus exercises for about 6 months at some point. My eyesight has not improved. I do notice completely different ability to read the chart during the day - sometimes I can read letters 5x smaller than the large letters, and sometimes I can barely read the large letters. Sunlight and how tired I am matter a lot - early in the day on 8+ hours of sleep like today means I can see almost as well as 20/20 (but at night I can't read the large numbers, though I can read the small with glasses). Sometimes doing the near-far focus exercises helps for the short term. Breathing deeply seems to help. I seem to have a ton of stress related issues breathing deeply helps relax.

Unfortunately, the tldr is that my vision has not objectively improved permanently.

Story of my life really - I very much question most people's ability to improve in most areas, but that's a different topic.

P.S. I have the same disbalance as most here - one eye is both faster to focus and sees better. I close one eye when I do near-far focus.

Very interesting reading. I have also been reading about insulin resistance and how one philosophy was to give more insulin, and another philosophy is to reduce insulin + add fasting so that your body corrects towards the new life [ maybe I am paraphrasing too much ]. From the little I have heard on this, reducing insulin and making body adapt sounds more reasonable. This seems to be going in a similar direction. Get…

This might all be a scam pushed by David Sinclair and his desire to spin up resveratrol companies. Apparently reducing insulin by reducing meal frequency or fasting does help reduce obesity, see "The Obesity Code". As far as the other magical benefits of fasting and cold showers and other "stressors" - specifically autophagy and neurogenesis - none of it is proven and can be considered a trend.

I do water-fast 3 days in a row once a month, and it does basically nothing for me (adversely or positively). This is very much a trend in my life - trying all these things to achieve pretty much nothing. I guess it's good to know with certainty though.
