Sunglass lens and sunglass optics for ocular photo-bio-stimulation

A sunglass lens or sunglass optic, wherein the sunglass lens or sunglass optic provides light transmission of 40% or more of ocular photo-bio-stimulation light measured within a light wavelength range of 450 nm-510 nm to an eye of a wearer of the sunglass lens or sunglass optic, wherein a light transmission curve spectra of the sunglass lens or sunglass optic when superimposed on or over a light absorption curve spectra of melanopsin and rhodopsin covers 50% or more of the melanopsin and rhodopsin absorption curve spectra, wherein a visible light transmission (VLT) of the sunglass lens or sunglass optic is 30% or less, wherein the sunglass lens or sunglass optic is designed to transmit an amount of red light, yellow light, and green light, sufficient to pass a regulatory traffic signal test or standard for color transmission of red light, yellow light, and green light, and wherein a visible light transmission peak of the sunglass lens or sunglass optic does not exceed 40% within a light wavelength range of 600 nm-750 nm.
