> whether eyeglasses gave some self-confidence, or if vision impairment somehow made affected kids more studious, or some shit like this
Being studious causes vision impairment. We noticed that a long, long time ago.

It's less being studious, and more that being studious tends to be correlated with spending time indoors more. It's the spending time indoors that causes it apparently.
Not quite. It’s the lack of spending time outdoors.
Plenty of studies for that, too.
(not strictly for "outside" though, you can also look out of the window regulary, it is so that your eyes refocus and relax )
Or maybe reading and spending time inside tends to ruin your eyesight. Or maybe it does, but only because it takes time away from active pursuits like sports!
Does anyone have pointers to research that teases out the causes and effects here?
This is a nice summary.
