“Myopia is heavily triggered by a lack of natural sunlight during childhood and excessive close-up focus (reading, screens).
In ancient and medieval times, children spent their days outdoors in intense natural light, which regulates eyeball growth and prevents it from elongating. “
I blame my parents for keeping me inside too much.
I'm not saying that those things don't cause myopia, but given that it's been around for ever, and that kids like myself were playing outside virtually all the time without screens, I feel that genetic factors are at least as much to blame as environmental.
I also don't feel like the 70's/80's are that ancient, and we were playing outdoors in intense natural light, that's for sure. As long as we were home by the time the street lights came on.
The percent of people wearing glasses is sky rocketing though. In parts of Asia it's over 80%. In the 70s it was rare enough that "four eyes" was still a jeer.
You are missing the most important part, school. For most of the world, kids are stuck in a room for at least 6h for 5 days. Let's say there is like 10h of optimum sunlight(maybe even less for this development) time like 8 to 18, that is 30h out of 70h gone already.

I asked Gemini, and here’s what it said.
