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.

Abstract: A rotational lens assembly reduces the size of a gap between a lens and a frame of an optical light engine projector assembly. The lens includes a thread structure arranged around the outside edge of the lens. The thread structure allows the lens to align and lock within the optical assembly via at least a partial rotation of the lens. In addition, the rotation of the lens during assembly results in a relatively small gap between the lens and the frame. The smaller gap, in turn allows the other components of the optical assembly to be manufactured with lower tolerances for variation, improving the overall performance of the optical assembly.

Abstract: An augmented reality (AR) or mixed reality (MR) eyewear display includes a frame with two lens rims. One of or both of the lens rims include eye-side lens installment features to remove or insert an eye-side lens into the lens rim. The lens rim includes a lens retention ring that extends around the lens rim between two ends of the lens retention ring positioned at a first side of the lens rim. The lens retention ring is configurable in an open state to remove or insert an eye-side lens in the first lens rim, and in a closed state to fix the eye-side lens in the first lens rim, wherein the two ends are farther apart from one another in the open state than in the closed state.
