Now re-read the post you're actually replying to and notice that I didn't say anything like what you appear to be responding to. I've never been worried about blue light. I sleep fine. And stayed away from social media because it seemed unhealthy to me from the start, so I've never been hooked on twitter/instagram/tiktok. I actually feel for the people who are obsessed with it, especially the number of journalists who seem to have defined their jobs and role in life around reporting what was said by whom on twitter. There seems to be a small trend forming around people exiting that particular sink hole and realizing immediate improvements in their life experience. I hope that situation continues to improve, but that's up to each person to decide whether social media is helpful or harmful for their life and goals. While I do spend a lot of time in front of a screen, I also get up regularly, stretch, walk around, take the dog out for a walk, etc. So I don't get tension headaches. If I feel uncomfortable at all, I do something about it. Your reply here makes a lot of assumptions about what you know about other people, their situations, what you know about this area of study, and what the solutions are. This is the actual issue that seems to make this light v dark mode discussion more difficult that it needs to be. What has been properly studied in this area is pretty thin as most areas of scientific inquiry go. So there really isn't much anyone can claim to know here with the levels of certainty you seem to express. Aside from that, you're being pretty aggressive about giving out unasked advice to people you don't know, whose situations you don't know. If you can't understand why someone like myself can read and understand everything you just said and none the less enjoy dark mode; if it bothers you that people claim dark mode benefits them in spite of your certainty that they are mistaken and this is just a matter of having the right information, then you might try accepting that people are different, start asking more questions, and dial down the unasked advice. You might happier and more pleasant company for it. Not everyone needs to be the same for you to be okay with the situation. You don't need to fix people. If anything you just need to understand more.
