Methods and devices are described that relate to spectral filters and associated eyewear that are specifically designed to mitigate the disruptive effects of electric lighting on the circadian clock that can cause sleep deprivation and other physiological and psychological maladies. An example wearable device for viewing a real or virtual environment includes one or more windows positioned 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 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 block circadian-rhythm-disruptive spectra from reaching the wearer's eyes while providing viewability of the real or virtual environment by allowing light outside of the circadian-rhythm-disruptive spectra to reach the wearer's eyes.

Sleep-aiding eyewear that prevents light which inhibits melatonin production from reaching the eye is described. The eyewear that is the object of the present disclosure has improved visibility over other methods of cutting off melatonin-inhibiting wavelengths of light, which enables the user to perform tasks, such as reading and typing, uninhibited. This is achieved in some embodiments using a Bragg grating comprising multiple layers of alternating reflective index material as a surface coating on the lens. This may be combined with lens-tinting, or antireflective coatings, in the eyewear. Furthermore, transition lenses which block melatonin-shifting light when there is a suitable external stimulus, such as blue light from a light emitting diode, are described. The presently described filters are also useful for electronic displays and functional light-transmitting materials.
