more likely the opposite, nearsightedness is related to a lack of exposure of the eye to sunlight during childhood.
introverted people are more likely to spend time indoor (away from the UV of sunlight) which lead to your observed correlation.
- JrProgrammer 5y agoDo you have any sources on this?
- sndean 5y agoNot sure about the correlation with being introverted, but the sunlight-nearsightedness correlation is pretty well established [0], specifically light in the near ultraviolet range [1]. There was a really interesting article on HN years ago about this, but I can't find it. The researchers suggested this effect was a good reason to mandate outdoor recess for children during the school day – maybe in Australia?

- dd36 5y agoWhat? None of the near-sighted people in my family spent more than normal time indoors. Likely the opposite. We were always outside.
- fpoling 5y agoI have high myopia and I had plenty of outdoor time in my childhood on par or even higher than my buddies who did not developed myopia. Less anecdotal evidence is prevalence of myopia in south-east Asia where people have more exposure to bright sun than in Europe. My pet hypothesis about myopia is exposure to high glycemic food like white rice or white bread that simulate growth just little bit too much that is enough to develop the eye few microns too big and cause myopia. But that hypothesis also has a lot of issues.
