Abstract: A lens module may include a transparent lens element, a lens shaping structure that is coupled to the transparent lens element, and a plurality of actuators that are configured to adjust a position of the lens shaping structure to adjust the transparent lens element. The lens shaping structure may include a plurality of extensions that are each coupled to a respective actuator. To ensure the lens shaping structure has desired curvature between the extensions, the lens shaping structure may have a portion in one or more segments between adjacent extensions that has a property with a different magnitude than an additional portion of the lens shaping structure. The portion between the adjacent extensions may have an increased or decreased rigidity relative to the additional portions. The portion between the adjacent extensions may have a different width, thickness, or Young's modulus compared to the additional portions.

Abstract: A lens module in a head-mounted device may include a fluid-filled chamber, a semi-rigid lens element that at least partially defines the fluid-filled chamber, and at least one actuator configured to selectively bend the semi-rigid lens element. The semi-rigid lens element may become rigid along a first axis when the lens element is curved along a second axis perpendicular to the first axis. Six actuators that are evenly distributed around the periphery of the semi-rigid lens element may be used to control the curvature of the semi-rigid lens element. The semi-rigid lens element may initially be planar or non-planar. For example, the semi-rigid lens element may initially have a spherically convex surface and a spherically concave surface. A tunable spherical lens may be incorporated into the lens module to offset a parasitic spherical lens power from the semi-rigid lens element.

Abstract: A head-mounted device may include one or more adjustable lens elements. The adjustable lens element may include a transparent substrate, a collapsible wall that forms an enclosed perimeter on the transparent substrate, and a flexible membrane on the collapsible wall that together define an interior volume. The interior volume may be filled with a fluid. The adjustable lens element may include a lens shaping component that applies a force to the collapsible wall to adjust a height of the collapsible wall relative to the transparent substrate, which in turn may be used to adjust the shape of the flexible membrane and thus the lens power of the lens element. The collapsible wall may have bellows that allow the collapsible wall to fold on itself when compressed, thereby minimizing unintended lateral movement of the collapsible wall.

Abstract: A transparent structure may have layers with curved cross-sectional profiles. The transparent structure may have inner and outer layers with curved portions formed by bending the layers. A display may be applied to one or more of the inner and outer layers. To reduce the strain applied to the display while being bent into a desired curvature, a carrier film may be used during bending operations. The carrier film may be modified with a patch or openings distribute the strain evenly across the display. Additionally or alternatively, a convex mold may be used to further decrease the strain on the display while being formed into the desired curvature.
