My psychiatrist gets all in a tizzy about blue light, and to mollify her I set up Night Light on my three devices. But I feel like the Blue Light Moral Panic is only a proxy for what we do on those devices close to bedtime. If I doomscroll Facebook for an hour and then I get on HN where a headline makes me irate and I get into a comments-war with a troll, you can bet I'll sleep badly and wake up ready to fight. Who cares about light at that point? Also: magnitude matters. Viewing a monitor is like writing a book by candlelight. It's not like I'm sitting outside watching the noonday Sun.
