Abstract
A thin film coating for an ophthalmic lens is provided, that comprises alternating layers of high and low index materials. The coating attenuates the transmission of light and has a spectral reflectance curve characterized by a reflectance of at least about 90% in a range from 320 nm to 420 nm, by 50% at 440 nm, by 5% or less at 460 nm, and wherein the spectral reflectance curve is monotonically or strictly decreasing between 420 nm to 460 nm.
