|20150153489||Light filters that minimize suppression of melatonin and loss of color perception - 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.||06-04-2015|
|20150017109||Phototherapeutic Near IR Fluorescent Light Filters - Ophthalmic lenses and light filters containing special additives that have fluorescence emission in the near infrared region of wavelengths—in order to enhance phototherapy for the human eye when it is exposed to sunlight and artificial lighting.||01-15-2015|
|20150015844||Light filters that simulate the transmission spectra of the ocular lens pigment with age - This invention relates to the use of light filters, for example sunglass lenses, that have transmission spectra characteristic of the pigment found in the human ocular lens and that correspond to different age groups and different darkness.||01-15-2015|
|20140139803||Ophthalmic lenses with melanin and ocular lens pigment having low fluorescence - 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.||05-22-2014|
|20130078205||Compound, Composition, and Method for Protecting Skin from High Energy Visible Light - A compound, composition, and method for the protection of skin from the harmful effects of radiation, and particularly the harmful effects of high energy visible (HEV) radiation, are disclosed. The compound is a melanin derivative that can be formulated into compositions containing the melanin derivative and a suitable carrier. The composition is topically applied to the skin to reduce the risk of photoaging and improve skin repair due to damage from radiation.||03-28-2013|
