Abstract: Eyeglasses and components thereof providing enhanced absorption to the wearer of light known for regulating mood and biological rhythms. The components include lenses designed to enhance and accentuate the absorption of particular wavelengths in the eye, including those wavelengths between about 400 and 490 nm, and for promoting this absorption in particularly sensitive areas of the eye.

Abstract: The invention relates to eyewear and lenses for controlling and/or blocking the absorption of particular bandwidths of light that can impact the physiology of the wearer. The eyewear lens is adapted to selectively permit the relatively greatest percentage of a light within a wavelength range of between about 400 and 490 nanometers. The eyewear lens selectively permits the passage of light of the given wavelength range over one or more subregions of the eyewear lens. The one or more subregions cover in total at most 25-50% of the lens. The peak transmission level within the range between about 400 and 490 nanometers is at least about 70% and the passage of light outside of the range between about 400 and 490 nanometers is less than about 70%.

Abstract: Systems, methods, and apparatus for providing a fluid and reduced-toxicity optical media with optical analysis and therapeutic energy delivery. An aspect of the invention provides an aqueous solution of increased-salinity of between about 1% and 35%. An increasing salinity in accordance with the invention provides improved transmissive efficiency at many wavelengths and less toxicity than many existing systems and methods. A catheter having integrated fibers for probing or treating internal lumens or other tissues can include a liquid-inflatable balloon or flushing mechanism using the solution for displacing blood or other obstructions in an optical path between the fiber and targeted tissue. Methods including spectroscopy can be employed with the solution for diagnosing medical conditions associated with diseased vessels or other tissues while reducing the risk of permanent damage resulting from the diagnosis.
