An ophthalmic lens that includes a lens material having two opposing curved surfaces, the curved surfaces defining a lens axis; and a light scattering region surrounding a clear aperture. The clear aperture and the light scattering region are substantially centered on the lens axis, and the light scattering region has a plurality of spaced apart scattering centers (e.g., on a lens surface and/or embedded in the lens material) sized and shaped to scatter incident light, the scattering centers being arranged in a pattern that includes a random variation in spacing between adjacent dots and/or a random variation in dot size.

Ophthalmic lenses with light scattering for treating myopia

A method includes providing an ophthalmic lens having a prescribed optical power, the ophthalmic lens having a surface having a base curvature corresponding to the prescribed optical power, and exposing a material at the surface to laser radiation sufficient to locally reshape the material to form a plurality of lenslets on the surface. The lenslets each have a corresponding optical power that differs from the prescribed optical power of the ophthalmic lens.

Ophthalmic lenses for reducing myopic progression and methods of making the same

An ophthalmic lens includes a first region corresponding to a first area of an optical surface of the ophthalmic lens and a second region corresponding to a second area of the optical surface of the ophthalmic lens different from the first area The second region has an optically-switchable component switchable between a first optical state and a second optical state different from the first optical state. In the first optical state the second region partially scatters or defocuses light incident on the second area.

Ophthalmic lenses with dynamic optical properties for reducing development of myopia

Methods and devices for treating a human child having myopia are disclosed. For example, a human child having myopia can be treated by wearing spectacles having one or two myopia control spectacle lenses.

Methods and devices for reducing myopia in children

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.

Using binocular rivalry for expanding color perception

A method of making a contact lens includes providing a cylindrical blank for the contact lens, the cylindrical blank including a first portion and a second portion. The first portion is formed from a homogenous, optically clear material and the second portion is formed from an inhomogeneous, optically-scattering material. The method includes shaping the cylindrical blank to provide the contact lens. The contact lens includes a first region surrounded by a second region, the first region being formed from the homogenous, optically clear material and the second region being formed from the inhomogeneous, optically-scattering material.

Contact lenses for reducing myopia and methods for making the same

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.

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.

Evaluating and reducing myopiagenic effects of electronic displays

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.
