Abstract:
A system is provided comprising an optical filter. The optical filter comprises a Cu-porphyrin dye compound. The transmission spectrum of the system has an average transmission across the wavelength range of 460 nm-700 nm of at least 60%. The transmission spectrum of the system has an average transmission across the wavelength range 400 nm-460 nm that is less than 75%.

Claim (Index 1):
A system to reduce glare and provide retina protection, comprising:\n an optical filter comprising a Cu-porphyrin compound, wherein the Cu-porphyrin compound has a structure of: or a salt, or a tautomeric form thereof,\n wherein each of R 9  through R 28  is independently H, Cl, Br, F, sulfonic acid, carboxylic acid, or carboxylic ester, wherein at least one of R 9 -R 13 , at least one of R 14 -R 18 , at least one of R 19 -R 23 , and at least one of R 24 -R 28  are not H and wherein at least two of R 9 -R 13 , at least two of R 14 -R 18 , at least two of R 19 -R 23 , and at least two of R 24 -R 28  are H; or two of adjacent R 9  to R 28  form an aromatic ring structure, and \n wherein the system reduces glare and provides retina protection when light is incident to the optical filter.
