There is actually very little evidence as of now, that blue light emitted by screens actually causes any significant long time damage.
Also most modern phones have this built in.
As someone who worked nightshift for 18 years I really think it does at least help sleep wise. I blocked Blue light a few hours before I want to sleep and when waking I'd use a sad/sun light when waking up.
I don't do it now but I'm convinced that's one of the reasons I managed it for so long.
Basically I'm saying blue light wakes you up and helps set your body clock but avoiding blue light for a while helps you sleep. I was never aware of any claims blue light is unhealthy but I guess it makes sense as you could argue the sun itself is bad for you.
Yes and that behavior is actually pretty well researched. There is a specific band which will result in the brain not getting into "sleep mode" sloppy said.
But there is no scientific proof that it is damaging to your eyes or harming your health in any other way.
Yeah this articles the first I've heard myself of blue light being unhealthy. I've always fancied some glasses that block it like gunnar glasses or something if nothing else it's helped me justify that purchase..
And yeah to me it's pretty set in stone blue light wakes you up.
