The methods of the present invention also include the use of optimized light filters and illuminants for use in treating diseases sensitive to modulation of intrinsically photosensitive retinal ganglion cells. The usefulness of the present method is that it results in the treatment of diseases and/or conditions related to light.

Abstract: Customized spectral profiles, and filters and illuminants having a customized spectral profile, optimized to reduce light in one or more wavelength regions for which one or more pigments are relatively more susceptible to perceptible changes in appearance.

Abstract: Computer program products comprising tangible computer-readable media having instructions that are executable by a computer to generate a customized spectral profile, which can be used to generate a corresponding filter. The instructions can comprise: generating a trial source spectrum; determining an uncorrected lamp source spectrum; calculating one or more optical indices using the trial source spectrum or the uncorrected lamp source spectrum; and optimizing one or more of the optical indices by varying the trial source spectrum to generate the customized spectral profile.

Abstract: Methods for generating a customized spectral profile, which can be used to generate a corresponding filter, lamp or other type of illuminant. A trial spectrum can be generated. A reference spectrum can be determined or otherwise obtained. A SOURCE spectrum can be determined or otherwise obtained. One or more optical indices can be calculated using the trial spectrum and one or more of the optical indices are optimized by varying the trial spectrum to generate the customized spectral profile. A radiation force parameter can be used to minimize unsafe build-up of light in spectral regions. Adaptations of color rendering parameters can be used in the optimization process. Smoothing parameters can be used to enable easier design of filter structures. A reflectance camera can be used to measure reflectance data at one or more pixels of a digital representation of an object to be illuminated.
