Abstract: The present disclosure provides metalloporphyrin and metallochlorin compounds (e.g., compounds of Formula (II) and (III)), which are useful in the preparation of optical devices (e.g., contact lenses, intraocular lenses, implantable contact lenses) that protect retinal pigment epithelium by the selective blocking of blue light. Also provided are precursor porphyrin and chlorin compounds (e.g., compounds of Formula (I)), and compositions and optical devices incorporating the compounds of the disclosure. Also provided are methods of selecting appropriate metalloporphyrin and metallochlorin compounds for incorporation into optical devices wherein the devices mitigate damage to retinal epithelial cells while balancing changes to luminous transmission, discomfort glare, color distortion, and disruption of circadian rhythms.

Abstract: Partially transparent devices and methods that reduce actual and/or perceived glare by incorporating absorbing materials are described. Actual and/or perceived glare can be reduced by multi-path absorption in the device. Perceived glare is further reduced by accounting for the psychophysics of human visual perception as a function of wavelength, orientation, and field illuminance.

Abstract: A system is provided that selectively blocks blue light in addition to having low overall transmittance values. The average value of the transmission spectrum of the system across the wavelength range 400 nm-470 nm is between 0% and 30% and the average value of the transmission spectrum across the wavelength range 470 nm-700 nm is between 0% and 70%. The transmission spectrum of the system has a first local minimum in transmission between 400 nm-470 nm.

Abstract: An improved dual-filter lens for protective eyewear that combines a first filter for blocking essentially 100% of UV light, and second filter for filtering blue light. The first filter may comprise a multi-layered dielectric mirror layer 14 or Rugate filter 50, and the second filter may comprise dye-impregnated lens layer(s) 16, 18 or Rugate filter 50. The first filter blocks essentially 100% of UV light, while the second filter establishes an increasing transmission profile that cuts on sharply at approximately 415 nm, and establishes an increasing transmission profile between approximately 415 nm to about 475 nm. The cut-on slope rises approximately 0.15% in transmissivity for every nanometer of increasing wavelength change, with a maximum filtering effect within the 440-465 nm range. These dual filters provide a balanced light transmission profile that reduces harmful tight transmission and prevents macular degeneration, cataracts and other ocular injuries, while still preserving visual acuity.

Abstract: Ophthalmic systems are provided that include both a photochromic component and a blue-blocking component.

Abstract: A system may be provided that comprises a substrate and a selective light wavelength filter that selectively blocks between 5 and 50% of light having a wavelength at or near 400-460 nm. The system may comprise any one of, or some combination of: a window, automotive glass, a light bulb, a flash bulb, fluorescent lighting, LED lighting, instrumentation, a display system, a visual system, a television, or a computer monitor.
