Abstract
An opto-physical material comprises a curable matrix composition and an effective amount of an ultraviolet light additive dispersed therein. The opto-physical material has a refractive index ranging from 1 to 1.8 at 589 nm wavelength and a light transmission value of 30% or less at any wavelength in the ultraviolet light spectrum. In addition, a test value of an optical physical property for the opto-physical material does not differ by more than 5% from a predetermined value of the optical physical property when the predetermined value is measured under the same measurement conditions for an opto-physical material comprising a comparative curable matrix composition lacking the ultraviolet light additive, wherein the optical physical property is selected from color shift in the visible light spectrum, light diffusivity at any wavelength in the light spectrum, light transmission in the visible light spectrum, and combinations thereof.
