Abstract
Ophthalmic lenses including a spectral filters (e.g., a reflective or absorptive spectral filter) are disclosed. A first of the spectral filters substantially blocks light in a first portion of a spectral sensitivity range of a cone (e.g., S, M, or L cone) and substantially passes light in a second, non-overlapping portion of the spectral sensitivity range. A second spectral filter substantially blocks light in the second portion of the spectral sensitivity range and substantially passes light in the first spectral sensitivity range.
