Abstract
Methods and devices are described that rely on interference filter designs to provide a precise and granular spectral behavior by allowing emissions of circadian-active blue and green light to reach a viewer. An example wearable device includes one or more windows positioned to allow light from a light source to propagate toward a position of a wearer's eyes, and a spectral filter that includes a coating positioned on one or more sections of the one or more windows. The spectral filter includes a multi-layer stack of dielectric material with alternate high and low indices of refraction. The number of the layers and a thickness of each layer are selected to provide designed transmission and blocking characteristics to allow circadian-active spectra to reach the wearer's eyes while blocking spectral content other than the circadian-active spectra. The designed transmission and blocking characteristics include a contiguous transmission region and two contiguous blocking regions.
