Lutein- Your screen emits the exact wavelength that it absorbs

Blue light (peak ~440nm) from screens and LEDs falls within the absorption spectrum of macular pigment (lutein + zeaxanthin, peak absorption 460nm). Macular pigment literally filters the specific wavelength your screen emits most. The "blue light protection" positioning for lutein isn't marketing spin, it's physics.Publications of interest:https://pmc.ncbi.nlm.nih.gov/articles/PMC11933726/, https://pubmed.ncbi.nlm.nih.gov/22465791/, https://pmc.ncbi.nlm.nih.gov/articles/PMC4698938/
