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.
