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 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 a lens module with a least one adjustable lens. The head-mounted device may be wirelessly paired to an electronic device such as a cellular telephone, watch, laptop computer, etc. To correct for presbyopia, the optical power of adjustable lenses in a head-mounted device may be adjusted when the user is viewing a close object. To allow for intelligent adjustments of the adjustable lenses while minimizing power consumption in the head-mounted device, the head-mounted device may receive sensor data and/or focal point change instructions from a paired electronic device. The paired electronic device may detect a trigger, analyze the user's attention to the paired electronic device, and send focal point change instructions to the head-mounted device based on the obtained information.

CPC classification number: G02B27/0172 , G02B3/14
Abstract: A lens module may include a first lens element, a lens shaping structure that is coupled to the first lens element, and a plurality of actuators that are configured to adjust a position of the lens shaping structure to adjust the first lens element. The lens module may also include a second lens element and a fluid-filled chamber between the first and second lens elements. To allow dynamic adjustments of the second lens element without requiring additional actuators, the second lens element may be a semi-rigid lens element. When the actuators adjust the curvature of the first lens element, the gauge pressure applied to the second lens element is changed. This causes a change in curvature of the second lens element. The actuators may therefore adjust the curvature of both the first and second lens elements even though none of the actuators are attached to the second lens element.

Abstract: A head-mounted device may have a display that displays computer-generated content for a user. The head-mounted device may have an optical system that directs the computer-generated image towards eye boxes for viewing by a user. The optical system may be a see-through optical system that allows the user to view a real-world object through the optical system while receiving the computer-generated image or the optical system may include a non-removable lens and a removable vision correction lens through which an opaque display is viewable. The optical system may include a removable lens. The removable lens may serve as a custom vision correction lens to correct for a user's vision defects. The optical system may have a projection bias lens that places computer-generated content at one or more desired virtual image distances and a corresponding compensation bias lens.
