Abstract
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 100 nanometers, wherein the compounds are photostable. The compounds substantially mimic the visible light absorbance properties of macular pigment while remaining photostable. The compounds may be used in a variety of articles, including ophthalmic devices.
