1. A light filtering device, comprising a plurality of adjacent layers forming a stack, wherein:
each of said layers comprising at least one material having a refractive index; wherein the refractive index of each of said layers is different than the refractive index of each of said adjacent layer; each of said layers having a predetermined thickness, wherein said thickness and said refractive index for each of said layers provide optical interference yielding to transmittance spectrum for the light filtering device being substantially equal to:
(1−melatonin action suppression spectrum) |
