Perhaps this is well known but I discovered this only two weeks ago - you can buy yellow-tinted glasses to block blue light. I wear them for an hour or so before bed (which my partner mocks me for) but it really seems to help me get to sleep. I'm not sure if that's the placebo effect of course but it does seem to work.

Every computer or phone I own has a screen display filter to rid those blues. Really helps reduce the artificial stimulation for me.

Once you get used to it, turn it back on sometime temporarily. It's incredibly blinding.
