Abstract: An article includes a first ophthalmic lens including a first spectral filter (e.g., a reflective or absorptive spectral filter), and a second ophthalmic lens including a second spectral filter (e.g., a reflective or absorptive spectral filter). 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 (e.g., S, M, or L cone) and substantially passes visible light having wavelengths in a second, non-overlapping portion of the spectral sensitivity range. 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.

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.

Abstract: A system includes a full-color electronic display, an eye-tracking module arranged to track an eye of a viewer of the display during operation of the system, at least one programmable processor, and a machine-readable medium storing instructions that, when executed by the at least one programmable processor to perform operations, including: (i) assessing uncorrected image data with one or more image frames, including determining an initial color of pixels in an image frame; (ii) assessing, based on data from the eye-tracking module, a location on the display where the viewer's eye is looking; (iii) modifying a color of red pixels from its initial color to a modified red color based on the location of the pixel relative to the location on the display where the viewer's eye is looking and the initial color of the pixel; and (iv) displaying, on the display, the image frames in which the one or more pixels have the modified color and other pixels have their initial color.

Abstract: Various techniques can be used to evaluate and reduce myopiagenic effects of electronic displays are disclosed. In one example, uncorrected image data corresponding to at least one uncorrected frame is assessed by identifying pixels having a red hue in the uncorrected frame(s). Modified image data is provided based on the uncorrected image data and the assessment. The modified image data corresponds to at least one corrected frame corresponding to the at least one uncorrected frame. Corrected frames are displayed, where one or more red-hued pixels in a corrected frame has a reduced degree of red saturation compared to the corresponding pixel in the uncorrected frame. The degree of red saturation in the red-hued pixels in the corrected frame is reduced based on a respective location of the pixels in the corrected frame.
