I usually don't agree with The Economist but I agree with them on this one, people spend too much time indoor and that's why there is an epidemic of shortsightedness. I would actually call it pandemic because it is affecting all developed countries because majority of their workforce works indoor and then goes home or to the gym....again indoor environment.

I heard it said that it's lack of UV that does the damage, glass filters out UV. Sounds like it might be a resolvable problem without having kids take class outdoor.

  Not a lack of Ultra Violet light, but a lack of Violet light, which also needs to be quite bright in order to have a proper effect. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8179197/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8179197/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5233810/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5233810/
