1. An ophthalmic lens comprising:
a polymerized lens comprising at least one polymer; and
a lens component configured to impart reduced light transmittance over a plurality of wavelength regions, comprising:
a first light transmittance-reducing dye configured to impart a first region of reduced light transmittance having a center located between about 485 nanometers and 510 nanometers;
a second light transmittance-reducing dye configured to impart a second region of reduced light transmittance having a center located between about 570 nanometers and 600 nanometers; and
a third light transmittance-reducing dye configured to impart a third region of reduced light transmittance having a center located between about 685 nanometers and 715 nanometers,
wherein reduced light transmittance is a reduction in % transmittance of at least 50% as compared to a region outside a reduced light transmittance region and between 400 nanometers and 680 nanometers,
wherein the ophthalmic lens comprises a polarizing wafer construct,
wherein the lens component configured to impart reduced light transmittance is an adhesive layer, and
wherein the adhesive layer resides between the polarizing wafer construct and the polymerized lens.
