  • Patent number: 11619831
    Abstract: A soft contact lens comprises a plurality of light sources coupled to a plurality of optical elements. The plurality of light sources and the plurality of optical elements are embedded in a soft contact lens material. Each of said plurality of optical elements generates an image focused in front of a peripheral retina of a wearer. In some embodiments, each of the images is focused at a distance in front of the peripheral retina at a location, and each of the images comprises a depth of focus and a spatial resolution. The depth of focus can be less than the distance, and the spatial resolution greater than a spatial resolution of the peripheral retina at the location.

  • Publication number: 20230063265
    Abstract: A contact lens charging case comprises a container sized and shaped to receive an electronic contact lens (“eCL”) and charging coil to couple to a coil of the eCL. In some embodiments, the charging coil comprises a diameter larger than a diameter of the coil of the eCL, so as to decrease sensitivity of the location and orientation of the eCL in the container and improve coupling between the coils. In some embodiments, the charging coil is dimensioned so as to extend at least partially around the container that receives the eCL.

  • Publication number: 20230026753
    Abstract: An OCT axial length measurement device is configured to measure an area of the retina within a range from about 0.05 mm to about 2.0 mm. The area can be measured with a scanned measurement beam or plurality of substantially fixed measurement beams. The OCT measurement device may comprise a plurality of reference optical path lengths, in which a first optical path length corresponds to a first position of a cornea, and a second optical path length corresponds to a second position of the retina, in which the axial length is determined based on a difference between the first position and the second position. An axial length map can be generated to determine alignment of the eye with the measurement device and improve accuracy and repeatability of the measurements. In some embodiments, the OCT measurement device comprises a swept source vertical cavity surface emitting laser (“VCSEL”).

  • Publication number: 20220413318
    Abstract: An apparatus to treat refractive error of the eye comprises one or more optics configured to project stimuli comprising out of focus images onto the peripheral retina outside the macula. While the stimuli can be configured in many ways, in some embodiments the stimuli are arranged to decrease interference with central vison such as macular vision. The stimuli can be out of focus images may comprise an amount of defocus within a range from about 3 Diopters (“D”) to about 6 D. In some embodiments, the brightness of the stimuli is greater than a brightness of background illumination by an appropriate amount such as at least 3 times the background brightness. In some embodiments, each of a plurality of stimuli comprises a spatial frequency distribution with an amplitude profile having spatial frequencies within a range from about range of 1×10?1 to 2.5×101 cycles per degree.

  • Publication number: 20220390768
    Abstract: An apparatus to treat refractive error of an eye comprises an electroactive component configured to switch between a light scattering or optical power providing configuration to treat refractive error of the eye and a substantially transparent configuration to allow normal viewing. The electroactive component can be located on the lens away from a central axis of the lens to provide light to a peripheral region of the retina to decrease the progression of myopia. The electroactive component can be located on the lens away from the central axis of the lens in order for the wearer to view objects through an optical zone while the electroactive component scatters light. The electroactive component can be configured to switch to the substantially transparent configuration to allow light to pass through the electroactive component and to allow the lens to refract light to correct vision and allow normal viewing through the lens.
