Abstract
The object of this invention is to provide optical articles having one or more transmittance-attenuating dyes. Each dye attenuates transmission of a certain wavelength range. Different dyes can be combined in different concentrations to tune the transmittance spectrum through a lens. The transmittance-attenuating dyes can be incorporated into different optical articles using different production methods.
