One possible explanation is that both problems have the same origin.
Another posible explanation was suggested in a paper that I read some time ago. They tested it with computer neural networks. It seems that basically you need the period of farsighted vision for the brain to develop properly, as it teaches it to process things holistically, as the whole pucture, which is what happenrd when the neural network was trained on blurry pictures at first. However, when trained on sharp pictures right from the start, it focused on random details, and had trouble learning to put the whole picture together, that is exactly the same problem as what is typical for nearsighted people.
However, I still believe that a common causative factor is more likely. The neural networks were artificial after all, and I don't think this is actually used in practice in AI.
had this thought myself while stoned growing up, inspired by the trope of the "blind seer" in greek mythology (maybe others). also from the little prince, "that which is essentially is invisible to the eyes." having poor vision could actually improve imagination, filling in blanks, pattern recognition, etc, leading to better brain function.
People who read books, read inside the room
People who are inside the rooms, dont go outside as much
People who dont go outside as much, dont adjust their eyes to see at distance
People who can't see at distance are classified as myopic
Because a too big brain takes up room the eyes would need to function optimally. Evolution finds local optima compromising between different strengths and weaknesses, very smart with myopia seems to be a deep local optimum for humans.
Myopia is just a result of looking at things up close for long periods of time. If society collapsed tomorrow and you were forced to live in the woods, your eyes would reaccomdate relatively quickly.
the first link upon a google search is endmyopia which is a well known pseduscientific hack "movement" with zero scientific evidence to back up their claims.

I actually know the guy who started endmyopia. Pretty chill dude. The results speak for themselves though, lot of people have done whatever it is endmyopia talks about and improve their vision.

Cool! Its impressive that he found the solution to an epidemic without a madical degree. Its almost like education can hinder your ability to make discoveries

>Its almost like education can hinder your ability to make discoveries
Surprisingly many big discoveries or inventions were made by people with very little education. Unironically it does, as education teaches you the wrong way. Theory is paramount, examples only illustrate the theory. This puts the cart before the horse and makes people fix the data instead of the theory, or make up some arcane explanation why the data doesn't actually contradict it

You're spot on, about examples illustrates the theory. I have realiaed that its better to read scientific papers instead of textbooks, because then you realise how hand wavy the theories presented in school as facts really are.
>In 2007, Queensland Health studied the lead levels of children living in Mount Isa aged between one and four years of age.13 Of 400 children tested, 11.3% had blood lead concentrations >0.48 μmol/L (10 μg/dL), [...] Repeated sampling in this same age group in 2010 showed the percentage of children with levels >0.48 μmol/L (10 μg/dL) reduce to 4.8%. [...] Since these reports were published, the Centers for Disease Control (CDC) has reduced the actionable limit of blood lead to 0.24 μmol/L (5 μg/dL).
>More recently in 2017, a pilot study assessing the blood lead of 30 children aged between one and seven years of age living in Mount Isa was published.15 Using the updated actionable limit of 0.24 μmol/L (5 μg/dL), 40% either reached or exceeded this level.

a bigger/longer eyeball causes myopia. the genes that increase eyeball size/length, due to being polygenic, spill over and make general human attributes bigger.
a bigger head is correlated with intelligence, and I think a rather straightforward causation can be implied here (bigger brains do tend to be more intelligent).
No the other way round, the deficiency makes you grow taller. It seems to be the effect must be indirect though, with lead regulating some other nutrient that regulates growth, rather than directly controlling the hormones etc.
inversely, yes
Cause reading given you myopia
What about watching science videos on youtube?
Depends on your distance from the screen/text. The further away, the better

Heres the answer fren
correlations generally do not mean anything
Correlations are correlated with causation
Is it actually correlated or is it just some notion you've cooked up from observing the world around you (and therefore prone to bias)
The correlation of correlations correlating with causation does not mean anything because correlation does not equal causation
why don't you ask your opia

>myopia correlate with intelligence
it correlates with being dysgenic

there is absolutely no evidence to support this claim
Look up "lense induced myopia". There is plenty of evidence that moving objects closer elongates the eyebulb

explain to me why my two eyes do not have the same myopia at all?
And why the myopia of my right eye is present since my birth?

why are threads starting with "why" so bad?
many people in japan or korea wear glasses. there is a hypothesis that it's related to the amount of time you spent outside during your childhood
if you're so intelligent why did you let your eyes get myopia
a bigger/longer eyeball causes myopia. the genes that increase eyeball size/length, due to being polygenic, spill over and make general human attributes bigger.
a bigger head is correlated with intelligence, and I think a rather straightforward causation can be implied here (bigger brains do tend to be more intelligent).
No. Myopia is caused by lead deficiency. Lead also regulates growth, so people grow bigger from the genetically normal ~162/150cm.
so i lead deficiency the reason I'm a manlet?
No the other way round, the deficiency makes you grow taller. It seems to be the effect must be indirect though, with lead regulating some other nutrient that regulates growth, rather than directly controlling the hormones etc.
>among people with myopia, people who want to read are more likely to get glasses
those are purely economic and social factors
Myopia is caused by looking at things up close a lot i.e. books and computas
