Are pervasive low blue light display features a waste of time?

University of Manchester scientists find that the common view on blue light is misguided.

Interesting. I use the blue light mode on my phone a lot, but not really for reducing the impact on my sleep etc - I use it just because I find it easier to read my screen in the dark with the filter enabled and brightness turned down - its just more comfortable :)

I don't use low blue light modes at all, I just leave the PC and the mobile alone for the last hour before bed.

I'm not a mouse.

How do you know that for sure, though?

I specifically replaced my old monitor for a low blue light model this year for this very reason so I'm really hoping this isn't true. I found using my PC at night use to wake me up. I've had low blue light on my phone for the same reason. I think it must have some affect as I have found it easier to fall asleep in some circumstances (but that could just be exhaustion from children waking me at night).

Well knocking out blue light on my screen would be daft in my case. I calibrate my screen so it is 'colour accurate' for the work that I do (design) and making it so 'white' is more of a yellow just isn't going to work.

It could also be a placebo effect - it works for you because you expect it to. But if it works, it works.

It's a rat study... In this case I can strongly argue against their findings, I've been using "low blue-light" since the time you had to install f.lux for it, and it already did a very noticeable difference when I started to use it, it was way more comfortable to use the PC when the filter was on at night, and I usually would go to bed sooner when using f.lux at night. Nowadays I'd say my brain/body have already adapted to think that yellow light means bed time as the effect is way stronger on me now. When I want to get things done at night, I must turn low blue light off, else I'll get sleepy very fast.

Someone better tell all of medical research that bridges009 isn't a mouse, they'll change methodology immediately.

Well if you insist on gaming when your asleep what did you expect?

I don't like to blow my own trumpet and it's not something I would normally boast about but, I'm not a cow.

I still use f.lux as it can be set to be a lot more gradual than the windows included one which is a hard switch. I like that you can set it by sunset in your area too. No idea if it works scientifically but if not the placebo works for me.

A lot of you is. Between 70 and 99% of your protein coding DNA is the same.

A low blue light mode still reduces the total amount of light, so even with the conclusions of this research it'd still be better than a non low blue light mode. All they're pointing out with this research is that blue light might not have the outsized effect most people believe it has, and just turning down brightness might be better.
