As one meta-analysis put it:
It’s estimated that an increase of one hour per day of outdoor time could reduce the occurrence of myopia in children by 45%.
Make sure your kids spend time outside, folks!

Same for me, I spent most of my free time as a child playing outside. I grew up in California, weather wasn’t a concern, I was outside year-'round. I got my first pair of glasses at age 21. I suspect it’s far more genetic than environmental.
It’s both. You can just look at the statistics, the number of people with myopia has gone up over the last few decades. If it was just genetics those numbers would have been stable.
Well, unless nearsighted people were outcompeting people with 20:20 vision, for some reason.
I’ve been told I look better with my glasses on.
