Abstract: An example head-mounted display device includes a light projector, an optical assembly arranged to direct light from a light projector to a user, and an actuator module. The optical assembly includes a variable focus lens assembly including a rigid refractive component, a shaper ring defining an aperture, and a flexible lens membrane between the shaper ring and the rigid refractive component and covering the aperture. The refractive component, the shaper ring, and the lens membrane are arranged along an axis. The refractive component and the lens membrane define a chamber containing a volume of fluid. The actuator module is configured to adjust an optical power of the variable focus lens by moving the shaper ring relative to the refractive component along the axis, such that a curvature of the lens membrane in the aperture is modified.

Abstract: A wearable device for projecting image light to an eye of a viewer and forming an image of virtual content in an augmented reality display is provided. The wearable device includes a projector and stack of waveguides optically connected to the projector. The wearable device also includes an eye tracking system comprising a plurality of illumination sources, an optical element having optical power, and a set of cameras. The optical element is disposed between the plurality of illumination sources and the set of cameras. In some embodiments, the augmented reality display includes an eyepiece operable to output virtual content from an output region and a plurality of illumination sources. At least some of the plurality of illumination sources overlap with the output region.

Abstract: In an example method for forming a variable optical viewing optics assembly (VOA) for a head mounted display, a prepolymer is deposited onto a substrate having a first optical element for the VOA. Further, a mold is applied to the prepolymer to conform the prepolymer to a curved surface of the mold on a first side of the prepolymer and to conform the prepolymer to a surface of the substrate on a second side of the prepolymer opposite the first side. Further, the prepolymer is exposed to actinic radiation sufficient to form a solid polymer from the prepolymer, such that the solid polymer forms an ophthalmic lens having a curved surface corresponding to the curved surface of the mold, and the substrate and the ophthalmic lens form an integrated optical component. The mold is released from the solid polymer, and the VOA is assembled using the integrated optical component.

Abstract: An open cell foam is used to create a seal between a camera and a shell piece. The shell piece, camera, seal and a transparent window form a closed front cavity. Because the cavity is closed, dust can remain away from a lens of the camera.
