My understanding was dopamine has the effect of stopping the eyeball from growing longer, which is released during exercise in the presence of bright sunlight. Hence a sedentary and indoor setting make you more prone to Myopia.

I don't have time to find a reference, but I have read research which shows that our eyes tend to grow longer when we are having any sort of trouble focusing, which is often the case with a weakened prescription or in dim light. As a result I stopped ordering slightly weaker glasses for myself and moved my office to a brighter room in the house.

Despite all that, my Myopia seems to be getting worse, wearing the appropriate glasses that ensure sharp focus for distance vision and ones that are less straining with a negative SPH value for computer work (hobby/weak reading glasses etc). I also have some astigmatism which my glasses are completely correcting now.

I would love for medical science to discover the means to reverse myopia, it seems like a solvable problem involving signalling/conditions which causes the eye morphology to change.

> dopamine has the effect of stopping the eyeball from growing longer, w Bilberry has been proven for this. If dopamine prevented myopia ADHD people on Adderall would not develop myopia. I'm aware that medical prescription correlates with symptoms are not public nor analysed but still that's a big if

Not sure if dopamine build-up in the striatum (or whatever the specific effect of dopaminergic amphetamines is) would be of any relevance. Could be a separate area of the brain, e.g. only specific to the visual system. Dopamine agonists reviewed in this journal article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5653403/

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 enclosed in the skull in all dimensions but one. My theory is my eyeballs lengthened because of the high IOP. My ophthalmologist says this is impossible. Unfortunately I am not scientifically literate enough to check that and I am not sure who to talk to.

What I am trying to say is, if your myopia is constantly worsening get your IOP tested - just in case.

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

[iengae]

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.

Can an amateur buy them online?

[iengae]

No definitely not. Your doctor has it. See https://en.wikipedia.org/wiki/Intraocular_pressure

[SemanticStrengh]

well it can actually be bought for 700$ but yeah doctors are a thing.

also: > Differences in pressure between the two eyes are often clinically significant, and potentially associated with certain types of glaucoma, as well as iritis or retinal detachment.

> 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/
