Abstract
Implementations of the present invention relate to apparatuses, systems, and methods for blocking, attenuating, or filtering neuroactive wavelengths of the visible light spectrum and reducing or preventing the symptoms affiliated with exposure to those wavelengths. Nanoparticles of a predetermined composition, size, and structure are dispersed in a host medium to create an optical notch filter, thereby attenuating only a narrow range of the visible spectrum.
