Abstract
Eyeglasses are described that have optical transmission curves capable of directing selected wavelengths of light to the eyes based on the response of intrinsically photosensitive ganglion retinal cells (IPGRC). In one embodiment, glasses for evening use are described that block blue portions of the visible spectrum. In another embodiment for evening use, blue portions are blocked but violet light is transmitted. In an embodiment for daytime use, blue light is transmitted and red light is blocked.
