1. A method of at least treating or preventing at least one light responsive disorder in at least one mammal, said method comprising the steps of:

  • utilizing at least one light source, said at least one light source emitting optical radiation;

    causing said optical radiation to be commonly therapeutically effective in humans by employing a pre-established spectral composition that has been pre-identified as a maximally potent spectral composition in the regulation of at least one of the human circadian, photoneural, or neuroendocrine systems, said pre-established spectral composition comprising at least one enhanced spectral region comprising at least one peak of emitted light within the range of 435-488 nm;

    exposing at least a portion of the retina of at least one eye of at least one mammal to said pre-established spectral composition of optical radiation such that said light source is not mounted on the body of said at least one mammal;

    stimulating the photoreceptor system for at least one of the circadian, photoneural or neuroendocrine systems of said at least one mammal;

    and, enabling at least the treatment or the prevention of at least one light responsive disorder in said at least one mammal.
