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.

Abstract: An augmented reality (AR) or mixed reality (MR) eyewear display utilizes an antenna arrangement for eyewear that optimizes the performance of the antenna without sacrificing the functionality or modularity of the eyewear. In one implementation, the antenna arrangement includes a first conductor that functions as a ground for the antenna, a second conductor configured to help retain a lens, and an antenna feed configured to excite the second conductor, causing the second conductor to act as an antenna. The first and/or second conductor additionally acts as a lens retention feature by interfacing with a groove in a lens and the use of a locking clip that prevents the lens from becoming dislodged from the second conductor, thus enabling quick and easy installation or removal of the lens.

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.
