The blue tint disrupts your sleep cycle and helps keep you awake when driving at night. There's definitely a trade off to be had depending on where these lights are located though.
It's not really the "blue" part. It's the "forcing yourself to be awake when you shouldn't be" part that disrupts your sleep cycle. Driving at night when you should be in bed is so much more the problem than whatever color the light is. For you as human at least =)
says what evidence? it's pretty much been debunked for a long time, and the whole premise is apparently based on bad science. I'm pretty sure i read an article here on hn that showed that this whole blue light scare was based on old science with extremely limited sample sizes and extreme exposure. i tried to link to an article from 2016 that still says that it affects sleep because i hastily read the first part. trying to dig up the article i read seems to be hard, but at least I'm still pretty sure that the science is not settled on the matter at all.
If you're referring to melatonin then the science really isn't that clear. Most light suppresses melatonin production.
One of the biggest arguments against blue light (specifically) being disruptive is that the sky spectrum in the evening is also blue (so naturally you'd be exposed to it). Modern airliners use blue lights for overnight flights with red lights at "dawn". I suspect screen brightness is more of an issue than any particular colour.
The dynamic range of the eye is confusing for aspects like this.
The amount of blue light you're exposed to from the night sky is trivial. Outdoors on a moonless night is 0.002 lux (of which, my understanding, about half is airglow and fairly blueish).
Compare to a not-too-bright single blue LED in your bedroom, emitting 0.5 lumens. You could spread that over 2000 square feet of surfaces and still have more blue light around than comes from the night sky.
