      That doesn’t change the fact tech companies just marketed it as an excuse to make one feel it is now “safe” to use their phone in bed in a flim-flam interpretation of science. You ever look at those blue filters on phones? Blue is still very present.

      Books still exist, other non-blue reading mediums, as do non-blue lights. Thus the “real science behind that” part.
