Photoprotection is the biochemical process that helps organisms cope with molecular damage caused by sunlight. Plants and other oxygenic phototrophs have developed a suite of photoprotective mechanisms to prevent photoinhibition and oxidative stress caused by excess or fluctuating light conditions. Humans and other animals have also developed photoprotective mechanisms to avoid UV photodamage to the skin, prevent DNA damage, and minimize the downstream effects of oxidative stress.

InactiveUS20050041299A1Increase contrastImprove visual acuityMountingsOptical partsRetinaLight filter
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.

Natural sunlight photostable composition
The present invention relates to photostable compositions that provide protection from ultraviolet radiation (“UVR”). The invention particularly relates to the sunscreens avobenzone, octocrylene and oxybenzone, forming a triplet sunscreen combination. Compositions of the present invention are generally substantially free of substantial amounts of other sunscreens. The triplet combination surprisingly provides and substantially maintains the initial SPF value of the sunscreen composition throughout the period of UVR exposure. Compositions of the invention are photostable such that each of sunscreen active in the triplet combination does not appreciably photodegrade. The present invention accurately communicates the amount of UVR photoprotection actually provided in natural sunlight and minimizes the amount of potential harmful free radicals formed as byproducts of photodegradation.
