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.

First claim

What is claimed is:

1 . An eyewear display comprising:
a lens retention ring in a first lens rim in a frame of the eyewear display, the lens retention ring comprising two ends positioned at a first side of the first lens rim, wherein the lens retention ring extends within the first lens rim between the two ends; and a detachable rim piece at the first side of the first lens rim, the detachable rim piece covering a cavity in which the two ends are positioned, wherein 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.

2 . The eyewear display of claim 1 , wherein the lens retention ring is configurable in the open state when the detachable rim piece is detached at the first side of the first lens rim, and wherein the lens retention ring is configurable in the closed state when the detachable rim piece is attached at the first side of the first lens rim.

3 . The eyewear display of claim 1 , wherein the lens retention ring is disposed between a waveguide carrier and a rear frame component of the frame of the eyewear display, wherein a waveguide is disposed on or integrated into the waveguide carrier.

4 . The eyewear display of claim 3 , further comprising a sealing ring positioned between the lens retention ring and the waveguide carrier.

5 . The eyewear display of claim 3 , further comprising a carrier pin in the waveguide carrier, wherein the lens retention ring comprises an opening in which the carrier pin is positioned.

6 . The eyewear display of claim 1 , further comprising a removable locking clip to lock the lens retention ring in the closed state when inserted into the cavity, the removeable locking clip to force the two ends of the retention ring closer together in the closed state from the open state.

7 . The eyewear display of claim 6 , wherein the removable locking clip comprises two notches, each notch to receive one of the two ends of the lens retention ring, wherein the removable locking clip comprises a protrusion to fit into a hole at the first side of the first lens rim.

8 . The eyewear display of claim 1 , wherein upon detaching the detachable rim piece, the lens retention ring is configurable in the open state by applying a separating force between the two ends of the lens retention ring.

9 . The eyewear display of claim 8 , wherein the lens retention ring comprises an elastic link joining the two ends of the lens retention ring, wherein the elastic link, in a relaxed state absent of the separating force, forces the two ends of the lens retention ring together in the closed state.

10 . The eyewear display of claim 1 , wherein the detachable rim piece is a detachable nose piece, and the first side of the first lens rim is a nose piece area of the first lens rim.

11 . The eyewear display of claim 10 , wherein the detachable nose piece comprises a locking mechanism to attach the detachable nose piece to the first lens rim at the noise piece area.

12 . The eyewear display of claim 1 , wherein the lens retention ring is partially enveloped with a silicone overmold, wherein the lens retention ring is in the closed state absent of a separating force between the two ends and is in the open state when the separating force is applied between the two ends to stretch the silicone overmold.

13 . A method comprising:
removing a detachable rim piece from at least one lens rim of two lens rims of an eyewear display to expose a cavity, the at least one lens rim comprising a lens retention ring, the lens retention ring comprising two ends positioned under the detachable rim piece in the cavity; triggering the lens retention ring to transition from a closed state to an open state, wherein the two ends are farther apart from one another in the open state than in the closed state; inserting an eye side lens within the at least one lens rim, wherein the eye side lens comprises a curvature corresponding to a vision correction prescription; triggering the lens retention ring to transition from the open state to the closed state to lock the eye side lens into the at least one lens rim; and re-attaching the detachable rim piece to the at least one lens rim to cover the cavity.

14 . The method of claim 13 , wherein triggering the lens retention ring to transition from a closed state to an open state comprises removing a locking clip attached in the cavity.

15 . The method of claim 14 , wherein triggering the lens retention ring to transition from the open state to the closed state to lock the eye side lens into the at least one lens rim comprises reattaching the locking clip to the loading cavity.

16 . The method of claim 13 , wherein triggering the lens retention ring to transition from a closed state to an open state comprises applying a separating force between the two ends of the lens retention ring.

17 . The method of claim 16 , wherein triggering the lens retention ring to transition from the open state to the closed state to lock the eye side lens into the at least one lens rim comprises removing the separating force.

18 . The method of claim 16 , further comprising removing a placeholder lens from the at least one lens rim prior to inserting the eye side lens within the at least one lens rim, the eye side lens occupying a void left by the removal of the placeholder lens.

19 . An eyewear display comprising:
a lens retention ring in a first lens rim in a frame of the eyewear display, the lens retention ring comprising two ends positioned at a first side of the first lens rim, wherein the lens retention ring extends within the first lens rim between the two ends, wherein 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; and
a detachable rim piece at the first side of the first lens rim, wherein upon being removed, the detachable rim piece triggers the lens retention ring to transition from the closed state to the open state.

20 . The eyewear display of claim 19 , wherein the detachable rim piece comprises one or more prongs, wherein upon being attached to the first side of the first lens rim, the one or more prongs apply a force to the two ends to cause the lens retention ring to be in the closed state.
