  • Light filters that minimize suppression of melatonin and loss of color perception
    Publication number: 20150153489
    Abstract: A light filter that utilizes UV and visible light-absorbing dyes with transmission spectra in accord with the action spectra for suppression of melatonin so as to permit a maximum production of melatonin in humans during night time exposure to high energy visible light.

  • Ophthalmic lenses with melanin and ocular lens pigment having low fluorescence
    Publication number: 20140139803
    Abstract: Fluorescence as a new source of haze caused by the light-filtering agent in ophthalmic lenses is introduced. A transparent ophthalmic lens comprising melanin as the light filtering agent with reduced fluorescence from melanin is described and the techniques used to quench the melanin fluorescence.
