As someone previously all-in w/ Blue Light glasses & using night features, there’s actually some research coming out that this is not really a thing either:
- #65 - Blue Screenlight is the Number 1 Sleep Myth of Our Time - Part 1!
- Forget What You Think You Know About Blue Light and Sleep | Time
I’m all for what’s ‘natural’ and chasing independence and being critical of whether or not companies have my best interest in mind. BUT I also don’t like denying science, and the science on blue light/EMF radiation/etc. is just not there.
My hunch is your health will improve by just limiting device exposure because you’ll be doing healthier things with your time than being on the internet 
So like @Ambrosio said just practice digital minimalism for your general mind & health.
