Abstract: 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 layer disposed on the optical path and includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. An illumination layer is also disposed on the optical path and is configured to propagate an evanescent activation light within the illumination layer. The illumination layer is also configured to leak the evanescent activation light towards the dimming layer to activate a darkening of the photochromic material of the dimming layer to dim the visible scene light.

Abstract: 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).

Abstract: A hybrid lens includes a primary lens element having a pair of opposing optical surfaces and a secondary lens element disposed directly over at least one of the optical surfaces. The primary lens element may include a 3D-printed layer, and the secondary lens element may be over-formed by casting. An electronic component such as a dimming component, a waveguide component, or an eye-tracking component may be integrated into the hybrid lens.

Abstract: 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.

Abstract: 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, wherein the dimming element includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. An illuminator, coupled to an edge of the dimming element, is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of the photochromic material to dim the visible scene light.
