In my family (n=basically_none), it seems that myopia correlates strongly with habits. The most bookish, indoors-y kids ended up in glasses - and the more so, the thicker the glasses - while folks who spent their childhoods running around outside tend to have 20/20 vision.
Assuming such an effect really exists, I expect it would be very difficult to statistically distinguish from straight heredity. Kids' early childhood habits tend to reflect family culture.
- typon 6y agoI read that being in the sun when you're a child and your eyes having to adjust with the change in brightness helps with reducing myopia
- amelius 6y agoPerhaps a good reason to buy a HDR monitor then :)
- mumblemumble 6y agoThe other hypothesis I've heard is that it's switching back and forth between focusing on close-up things and distant things. Which you naturally do a lot when engaging in outdoor activities, but basically not at all when staring at books or screens.
- toast0 6y agoOTOH, perhaps those who are starting to have myopia aren't going to want to do outdoorsy things because they tend to require far-seeing. If I can't see what's going on far away, I'm not going to have a fun time with most sports, and I'd rather read a book.
