ABSTRACT:
This disclosure relates to the application of a photoluminescent material with a plurality of nanocrystals, such as quantum dots or Cornell dots, each capable of absorbing electromagnetic energy at a first wavelength and emitting the absorbed energy as a desired wavelength in the direction of a human retina. Preferably, the emitted wavelength is chosen for its ability to suppress naturally occurring melatonin, i.e., blue light. The disclosure also contemplates the placement of the photoluminescent material over the entire surface of a lens or on a portion of the lens to optimize the exposure to the desired wavelength while reducing the overall luminescence. Finally, the photoluminescent material can be applied as a coating, as part of a material applied to the lens, either superficially or in/within the lens, as part of eyewear, or even as an optical treatment system.
