Abstract
Methods and devices are described that relate to spectral filters and associated eyewear that are specifically designed to block emissions of circadian-active blue light to reach the observer. 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 comprises 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. The number and thicknesses of the layers are selected to provide designed transmission and blocking characteristics. The designed characteristics include a contiguous blocking region that blocks 98-100% of the circadian-active spectra and two contiguous transmission regions that transmit 80%-100% of the spectral content outside of the circadian-active spectra.
