Photostable mimics of macular pigment

Described are visible light absorbing compounds. The compounds have a visible light absorption maximum between 430 and 480 nm and a full width half maximum (FWHM) at the visible light absorption maximum of at least 35 nm and up to 150 nanometers, wherein the compounds are photostable. The compounds...

Beschreibung
Zusammenfassung:	Described are visible light absorbing compounds. The compounds have a visible light absorption maximum between 430 and 480 nm and a full width half maximum (FWHM) at the visible light absorption maximum of at least 35 nm and up to 150 nanometers, wherein the compounds are photostable. The compounds are also thermally stable. The compounds substantially mimic the visible light absorbance properties of macular pigment while remaining photostable and thermally stable. The compounds may be used in a variety of articles, including ophthalmic devices. Formula (I):
