1. An article, comprising:
a first ophthalmic lens comprising a first spectral filter, an first absorptive linear polarizer, and a first quarter wave plate arranged between the first spectral filter and the first absorptive linear polarizer; and
a second ophthalmic lens comprising a second spectral filter, an second absorptive linear polarizer, and a second quarter wave plate arranged between the second spectral filter and the second absorptive linear polarizer,
wherein the first spectral filter substantially blocks visible light having wavelengths corresponding to a first portion of a spectral sensitivity range of a first type of cone and substantially passes visible light having wavelengths in a second, non-overlapping portion of the spectral sensitivity range, and
the second spectral filter substantially blocks visible light having wavelengths in the second portion of the spectral sensitivity range and substantially passes visible light having wavelengths in the first spectral sensitivity range.
