Anecdote: I live in Asia, and when I was in middle school, AFAIR there were only 3 people (out of 40-ish) don't wear glasses including me.
Parents nowadays blame screens for short-sightedness, but the truth is back then my classmates are almost all doing reading and writing all the time, and nobody was using screens (Symbian Nokia only took off years later).
It's only me and the other two boys who spend all the time and money on online video games - the other two guys were almost score zero in every single exam.
