Abstract: A multi-material eyewear device that can be utilized in an augmented reality (AR) or mixed reality (MR) eyewear display system includes an upper portion composed of a different material from one or more lower portions. The upper portion has a higher stiffness or stiffness-to-mass ratio than the lower portions, is less RF-permeable than the lower portions, and/or has a higher thermal conductivity than the lower portions. One or more antennas bonded to, housed in, or coextensive with the lower portions operate with high performance and efficiency due to the lower portions having higher RF-permeability than the upper portions, while the multi-material eyewear device maintains a high overall stiffness or stiffness-to-mass ratio due to the stronger material of the upper portion.

Abstract: A display system comprises a first frame structure housing one or more processors and wearable proximate to a user's eye, and a second frame structure coupled to a light engine and various optical elements. The light engine generates display light indicative of graphical content, with the optical elements channeling the display light to the user's eye. The processors of the first frame structure control operations of the light engine via a selectively detachable connection between an electromechanical interface of the first frame structure and a corresponding electromechanical interface of the second frame structure.

Abstract: An eyewear display includes a frame comprising two lens rims and a nose bridge, a first lens rim of the two lens rims holding a lens stack including a first lens (e.g., a world-side lens) and a waveguide. A detachable rim piece is attached to the first lens rim, and, upon being detached from the first lens rim, the detachable rim piece exposes a loading cavity housing a lens retention component. The lens retention component is removable from the loading cavity to insert a second lens with a vision correction prescription within the lens stack of the first lens rim. The lens retention component is then re-inserted into the loading cavity to fix the second lens (e.g., an eye-side lens) into the lens stack of the first lens rim. The detachable rim piece is then re-attached to cover the loading cavity and the lens retention component.
