I've spent a few hours looking into myopia. You're correct that it's been increasing and is still increasing, it's increased so quickly genetics can't explain it, and the sunlight hypothesis is new to me. Some areas in Asia have >80% myopia rates. (As an ally myself, I also think it's worth pointing out that Gen-Z having a 7% LGBTQ rate theoretically could also have an environmental cause. There is evidence of a biological basis for transexualism.) [1] https://en.wikipedia.org/wiki/Near-sightedness#Asia https://en.wikipedia.org/wiki/Near-sightedness#Asia

Personally I think the increase in LGBTQ people would most likely be caused by increasing public acceptance and/or awareness - if you're going to be ostracized by everyone you know it's a lot harder to come out, and if you think feeling however you do is bizarre/unprecedented/obscene you similarly won't tell people. Plenty of anecdotes out there of people who didn't think they were gay/bi/trans/etc because they didn't think of it as a thing-you-could-be; you see things like "oh, I thought everyone thought girls were hot" (or equivalent). As acceptance and awareness grow, the bar gets lower -- fifty years ago it'd take a lot of dysphoria to justify trying to transition; now it's still not simple but it's a lot easier, and so more people who are comparatively less dysphoric are willing to take that particular plunge, and more of them know it's a doable thing.
