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.
- TylerE 3y agoRed is also really low contrast, at least at non-night-vision destroying lumen levels.
- Galaxeblaffer 3y agosays 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. earlier posted article https://medicalxpress.com/news/2016-04-debunking-digital-eyestrain-blue-myths.html https://medicalxpress.com/news/2016-04-debunking-digital-eye...

- joshvm 3y agoIf 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.
- mlyle 3y agoThe 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.
- TylerE 3y agoLux != lumen. Lux is lumen per unit area.
- BenjiWiebe 3y agoIsn't that what they are saying? 0.5 lumen spread out over 2000 sq feet is still more lux than the night sky?
- mlyle 3y ago> Lux != lumen. Lux is lumen per unit area. Yes... that is why I divided by area. It's kind of sad how many of us end up so impatient over common mistakes that we screw up just as badly in our eagerness to snap at people. Obviously it's fudged a bit. The LED is not an isotropic emitter, and it's not at the center of a spherical room with perfectly reflective walls. In practice, I suspect the amount of blue illumination from one dim blue LED in a large bedroom and the night sky are pretty much equal.
- mainframed 3y agoI'm not referring to anything. I just found it hilarious that the guy, to whom I replied, linked an article which contradicted himself. I have no stance on this. I don't even care. I can sleep well at night.

- TheRealPomax 3y agoIt'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 =)
- ketzo 3y agoThat's the point -- the blue is to help break the cycle further and keep you awake, when your body insists otherwise!
