    摘要： A pair of electronic eyeglasses includes an eyeglasses frame and an eyeglasses lens mounted within the eyeglasses frame. At least one femtoprojector is embedded within the eyeglasses lens. The femtoprojector includes an image source and an optical system that projects an image from the image source onto the retina of the wearer. The femtoprojector is small enough that is does not significantly interfere with the wearer's view through the eyeglasses lens.

    摘要： An electronic contact lens can address the effects of presbyopia, aiding a user in adjusting focus when viewing objects at different distances from the user. The electronic contact lens includes a liquid crystal matrix. When the electronic contact lens is configured to operate in a reading mode, an aperture is formed within the liquid crystal matrix by configuring elements of the liquid crystal matrix immediately surrounding the aperture to block light from passing through the surrounding elements. The resulting aperture increases the focus of light passing through the aperture as a result of the pinhole effect. The aperture can be centered within the user's visual axis, and the location within the liquid crystal matrix corresponding to the user's visual axis can be determined during a calibration of the electronic contact lens.

    摘要： In some designs, an eye-mounted display includes multiple femtoprojectors contained inside a contact lens. Femtoprojectors that project to peripheral regions of the retina can have lower resolution. In some designs, these peripheral femtoprojector optical system includes an optically transparent core with two ends. The image source is located at one end, and a lens element is located at the other end. The end with the image source is the same size or larger than the end with the lens element. The core may be a cylinder or a frustum, for example. The sidewall structure extending between the two ends is designed to reduce stray rays from the image source. For example, the sidewall structure may absorb stray rays or may redirect rays so that they do not exit the core or so that they do not enter the pupil of the eye.

    摘要： An electronic contact lens contains electrical components connected by an electrical interconnect. The electrical interconnect has a flat body, with electrical conductors running length-wise along the body. The flat body is oriented perpendicular rather than parallel to the inner and outer surfaces of the contact lens to reduce a visible profile of the interconnect, reducing the amount of light blocked from entering the eye. The body has a curvature shaped to conform to the curvature of the contact lens. As examples, the interconnect may be connected with an electrical component using a tab perpendicular to the flat body of the interconnect, or by forming an edge connection with electrical contacts of the component located along an edge of the component, or through one or more exposed vias formed on the component.

    摘要： An electronic contact lens includes multiple femtoprojectors within the contact lens. Different femtoprojectors project images onto different portions of the retina. The images can be aligned by an alignment circuit within the contact lens. The alignment circuit can adjust the physical position or orientation of one or more femtoprojectors. Additionally, the alignment circuit can configure a location within a femtoprojector array from which an image is projected. A user can provide an input to align the femtoprojectors. For instance, a user can provide an input to adjust a location from which a first femtoprojector projects a test image until the test image is aligned with a test image projected by a second femtoprojector. The alignment circuit can, based on the user's input, determine alignment information for the femtoprojectors, and the contact lens can project subsequent images based on the alignment information.

    摘要： A pair of eye-mounted displays includes a right eye-mounted display and a right eye-mounted display. Each eye-mounted display comprises a contact lens. A femtoprojector system in each contact lens projects an image onto a retina of a user's eye when the contact lens is mounted on the user's eye. When the pair of eye-mounted displays is mounted on the user's left eye and on the user's right eye, a left-eye image is projected onto the user's left eye retina and a right-eye image is projected onto the user's right eye retina. The two projected images only partially overlap within the user's binocular visual field.

    摘要： An augmented reality system including a source and a contact lens display can be used to project information from the contact lens display onto the retina of the wearer's eye. The source provides energy to the contact lens display and operates at a source frequency. The source includes a source circuit including a conductive coil. The contact lens display includes a resonant circuit including another conductive coil and a capacitive circuit. The resonant circuit receives energy from the conductive coil of the source via a magnetic field inductively coupling the conductive coils. The contact lens display additionally includes a feedback circuit to adjust the capacitance of the capacitive circuit to control a resonant frequency of the resonant circuit. The feedback circuit can control the capacitive circuit to maintain the resonant frequency of the resonant circuit near the source frequency as the wearer's eye blinks.
