Abstract: Systems include three optical elements arranged along an optical axis each having a different cylinder axis and a variable cylinder refractive power. Collectively, the three elements form a compound optical element having an overall spherical refractive power (SPH), cylinder refractive power (CYL), and cylinder axis (Axis) that can be varied according to a prescription (Rx).

Abstract: A method for displaying an image using a wearable display system including directing display light from a display towards a user through an eyepiece to project images in the user's field of view, determining a relative location between an ambient light source and the eyepiece, and adjusting an attenuation of ambient light from the ambient light source through the eyepiece depending on the relative location between the ambient light source and the eyepiece.

Abstract: Techniques are described for operating an optical system. In some embodiments, light associated with a world object is received at the optical system. Virtual image light is projected onto an eyepiece of the optical system. A portion of a system field of view of the optical system to be at least partially dimmed is determined based on information detected by the optical system. A plurality of spatially-resolved dimming values for the portion of the system field of view may be determined based on the detected information. The detected information may include light information, gaze information, and/or image information. A dimmer of the optical system may be adjusted to reduce an intensity of light associated with the world object in the portion of the system field of view according to the plurality of dimming values.

Abstract: A wearable display system includes an eyepiece stack having a world side and a user side opposite the world side. During use, a user positioned on the user side views displayed images delivered by the wearable display system via the eyepiece stack which augment the user's field of view of the user's environment. The system also includes an optical attenuator arranged on the world side of the of the eyepiece stack, the optical attenuator having a layer of a birefringent material having a plurality of domains each having a principal optic axis oriented in a corresponding direction different from the direction of other domains. Each domain of the optical attenuator reduces transmission of visible light incident on the optical attenuator for a corresponding different range of angles of incidence.

Abstract: Techniques and mechanisms to facilitate implantation of an ophthalmic device in an eye. In an embodiment, the ophthalmic device includes multiple housing structures (housings), where components of the ophthalmic device are variously disposed in respective ones of such housings. The housings are flexibly coupled each to a respective other one of such housings. One or more flexible interconnects of the device allow for articulation of the housings during implantation in an eye. In another embodiment, first circuitry disposed in one housing facilitates operation of the ophthalmic device to sense a condition at the eye or to assist sight with the eye. Second circuitry, disposed in another of the housings, is electrically coupled with the first circuitry via a flexible interconnect.
