Every time people talk about "Blue light" it's a problem precisely because it's like the light we get from the sun, it mucks up our circadian rhythm and keeps us awake. Or it's bad for our eyes because reasons, even though "there is no good evidence that filtering blue light with spectacles has any effect on eye health, eye strain, sleep quality or vision quality" (Wikipedia).
So if tablets do the same thing the sun does and keep us awake, that must mean kids in very sunny areas have early puberty as well? Those up in the tropics with a consistently large amount of sun year round, for example?
Even simple logic deduction, this story makes no sense. And when the truth comes out, it'll probably be something like "Exposing rats to the equivalent of 20 suns worth of blue light causes early puberty and death"
- Aerbil313 3y agoPuberty age in tropical regions is lower. As you near the poles, it gets higher. This is why people in higher latitudes are longer in average. Growth hormone’s release slows down when puberty is reached.
- Jensson 3y ago> are longer in average When you write this people think about genital length. I've done that mistake as well, easy to make as a non native speaker, to get the right point say "taller" not "longer".
- TeMPOraL 3y agoEven if the blue light from electronics had any significant effect, my first instinct would be to say, it's a wash: the amount of time spent with such electronics correlates strongly with amount of time spent indoors and away from sunlight. If anything, this would be bringing us closer to status quo from 50+ years ago.

[1] https://ifstudies.org/blog/poverty-and-early-puberty-in-australian-children https://ifstudies.org/blog/poverty-and-early-puberty-in-aust... So, there is another way to explain what we see.
- korm 3y ago> there is no good evidence that filtering blue light with spectacles... That's likely referencing this recent review[1]. The products referenced don't actually reduce blue light by much, which you can confirm in the studies. The lenses look transparent, not amber in many cases. Which makes sense because they're meant for all day use, but it's just a marketing thing. If you bought glasses in person in the last 10 years, they probably tried to upsell a blue light or "screen strain reduction" filter. It's a stretch to hold this as evidence that blue light doesn't affect us. [1] https://doi.org/10.1002/14651858.CD013244.pub2 https://doi.org/10.1002/14651858.CD013244.pub2
- nullserver 3y agoUsed to have extreme migraines. Any exposure to Fluorescent light would leave me mentally disabled within 10 minutes. So I could enter any grocery stores. Or go into work. Blue light filter glasses did little to nothing. I got some FL-41 glasses that covered top and sides. I would be fine for about 2 hours under those lights. Eventually light leakage would get to me. But it made a drastic difference.
- fnordpiglet 3y agoFascinating, I would have thought it was the flickering of fluorescent that was getting you. I know CGA / EGA monitors with 60hz refresh rates really bothered me and gave me headaches and it was miserable to program at that time for me. It’s interesting that FL-41 glasses help you, I’m glad to hear you’ve found something that helps. That sort of pain awful and functionally frustrating.
