The disclosed system may include at least one gradient-index liquid crystal lens. The system may include a selection module that selects a viewing angle. The system may also include an adjustment module that dynamically adjusts a phase reset property of the gradient-index liquid crystal lens in response to the selected viewing angle. Various other devices, systems, and methods are also disclosed.

Gradient-index liquid crystal lenses with adjustable flyback regions

A device includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and a liquid crystal layer disposed between the primary electrode and the secondary electrode, where the primary electrode has a spatially variable electrical resistance.

An optical assembly is configured to receive visible scene light at the backside of the optical assembly and to direct the visible scene light on an optical path toward the eyeward side. The optical assembly includes a dimming element disposed on the optical path, where the dimming element includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. A display layer is disposed on the optical path between the eyeward side of the optical assembly and the dimming element. The display layer is configured to direct visible display light toward the eyeward side and also to direct activation light to the dimming element, where the activation light is within the range of light wavelengths to activate a darkening of the photochromic material to dim the visible scene light.

An apparatus, system, and method for a lens assembly for a head-mounted device includes a frame and a lens assembly. The lens assembly is configured to be carried by the frame. The lens assembly includes a lens bulk, an edge thickness, and a power layer. The edge thickness includes a predetermined thickness value that is configured to be compatible with (e.g., a slot in) the frame. The power layer is configured to be set to one of a number of predetermined power levels while maintaining the edge thickness within the predetermined thickness value. The power layer is configured to define a course power level of the lens assembly (e.g., in the range of −6.00 D to +6.00 D).
