Abstract
Described are contact lenses containing light absorbing chromophores, wherein the light absorbing chromophore is concentrated in one or more select regions of the lens. Also described are methods for making such contact lenses.
Claims22
A contact lens comprising:
- a first region;
- a second region;
- a visible light absorbing chromophore;
- and
- a derivative of the visible light absorbing chromophore,
- wherein the first region contains the visible light absorbing chromophore and the second region contains the derivative of the visible light absorbing chromophore,
- and wherein the second region has a greater average percent transmission than the first region across a wavelength range of 400 nm to 600 nm.
