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.
Claims17
An article, comprising:
- a first ophthalmic lens comprising a first spectral filter;
- and
- a second ophthalmic lens comprising a second spectral filter,
- 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,
- wherein at least the first ophthalmic lens further comprises a filter array comprising the first spectral filter.
