Abstract: 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.

Abstract: Light filters that use yellow melanin or melanin like materials prepared to have a yellow color and a melanin transmission spectrum in combination with a photochromic dye are disclosed. The yellow form of melanin has minimal impact on the perception of light intensity with transmission values greater than 80%. The combination allows for a single light filter suitable for both night driving and sunglass applications and which also preserve color perception.

Abstract: The present invention relates to the use of water soluble melanin in solid plastic films of polyvinyl alcohol to be used in conjunction with other plastics to make laminated sheets or lenses. Such laminates will be used as filters to protect against photochemical damage from electromagnetic radiation.

Abstract: This invention relates to the field of eye protection and vision enhancement by filters of UV and the higher energy visible (HEV) light—such as sunglass lenses. More specifically, it relates to the process of tinting plastic films and sheets with solutions of synthetic melanin. Such plastic films may include sunglass lenses, and ophthalmic lenses in general, windows, light filters such as photograph covers, canopies, etc., and other similar media utilized to protect valuable goods from radiation damage.

Abstract: The present invention is directed to a transparent medium incorporating the oxidative polymerization product of 3-hydroxykynurenine, a synthetic version of the yellow-to-brown pigment that occurs in the ocular crystalline lens with age. Because this coloration in the ocular lens is believed to offer photoprotection to the retina, it may represent an ideal sun lens filter with an optical transmission spectrum that is compatible with the psychophysical and neurophysiological characteristics of the vision system.

Abstract: A cable length adjusting device includes a cable located within a conduit, which is fixed against displacement at longitudinally spaced positions. A first end of the cable includes a fitting fixed to a ball stud extending from a lever whose position is a reference position. At the opposite end of the cable a fitting engages a ball stud extending from another lever. A spring clip in a form of a compression spring forces a rod end, fixed to one end of the cable, away from the location of the second ball stud and toward the reference position. A cable adjusting screw fixes the rod and spring clip in position on the second fitting.
