The frame assembly includes a face portion for supporting at least one waveguide that creates an eye box, a support rest for supporting the face portion on a user, and a coupling for adjusting the position of the face portion relative to the support rest. This enables movement of the waveguide eye box relative to the support rest to position the eye box in front of the wearer's eyes. ## Claims ### Claim 1 An adjustable waveguide assembly for augmented reality eyewear, the waveguide assembly comprising: a frame comprising a first prism and a first projector operable to project light containing an image into the first prism; at least one waveguide movably mounted in the frame and adapted to move horizontally with respect to eyes of a wearer, the at least one waveguide comprising a second prism configured to receive light from the first prism in parallel to the at least one waveguide and to reflect the light received from the first prism into the at least one waveguide at a predetermined angle; and at least one coupling for adjusting a horizontal position of the at least one waveguide relative to the frame, wherein, in response to operation of the at least one coupling, the second prism is movable relative to the first prism while receiving light from the first prism. ### Claim 2 (depends on 1) The adjustable waveguide assembly according to claim 1, wherein the at least one coupling comprises a threaded coupling. ### Claim 3 (depends on 2) The adjustable waveguide assembly according to claim 2, wherein the at least one waveguide comprises a first threaded element and the frame comprises a second threaded element that mates with the first threaded element. ### Claim 4 (depends on 3) The adjustable waveguide assembly according to claim 3, wherein the first threaded element comprises an external thread on the at least one waveguide, and the second threaded element comprises an internal thread in the frame. ### Claim 5 (depends on 4) The adjustable waveguide assembly according to claim 4, wherein the at least one waveguide comprises a threaded post, and the external thread extends around a circumference of the threaded post. ### Claim 6 (depends on 5) The adjustable waveguide assembly according to claim 5, wherein the frame comprises a rotatable dial defining a bore, and the internal thread extends inside the bore. ### Claim 7 (depends on 6) The adjustable waveguide assembly according to claim 6, wherein the dial is rotatable relative to the frame to axially displace the at least one waveguide relative to the frame. ### Claim 8 (depends on 1) The adjustable waveguide assembly according to claim 1, wherein the at least one waveguide comprises a first waveguide and a second waveguide. ### Claim 9 (depends on 8) The adjustable waveguide assembly according to claim 8, wherein the at least one coupling comprises a first adjustment coupling that movably connects the first waveguide to the frame, and a second adjustment coupling that movably connects the second waveguide to the frame. ### Claim 10 (depends on 9) The adjustable waveguide assembly according to claim 9, wherein the first waveguide comprises a first input coupler and a first output coupler, and the second waveguide comprises a second input coupler and a second output coupler. ### Claim 11 (depends on 10) The adjustable waveguide assembly according to claim 10, further comprising a second projector operable to project light containing an image into the second waveguide. ### Claim 12 (depends on 11) The adjustable waveguide assembly according to claim 11, wherein the first output coupler is configured to produce an image in a first eye box, and the second output coupler is configured to produce an image in a second eye box. ### Claim 13 (depends on 12) The adjustable waveguide assembly according to claim 12, wherein the first adjustment coupling is operable to adjust the position of the first eye box relative to the frame, and the second adjustment coupling is operable to adjust the position of the second eye box relative to the frame. ### Claim 14 (depends on 13) The adjustable waveguide assembly according to claim 13, wherein the first adjustment coupling is operable in a first direction to move the first eye box to the left relative to the frame, and operable in a second direction to move the first eye box to the right relative to the frame. ### Claim 15 (depends on 14) The adjustable waveguide assembly according to claim 14, wherein the second adjustment coupling is operable in the first direction to move the second eye box to the left relative to the frame, and operable in the second direction to move the second eye box to the right relative to the frame. ### Claim 16 (depends on 11) The adjustable waveguide assembly according to claim 11 further comprising a first housing attached to the frame and a second housing attached to the frame, the first housing containing the first projector and the second housing containing the second projector. ### Claim 17 (depends on 1) The adjustable waveguide assembly according to claim 1 further comprising at least one temple, the at least one temple attached to an end piece for supporting the waveguide assembly on a user's ear. ### Claim 18 (depends on 17) The adjustable waveguide assembly according to claim 17, wherein the at least one temple comprises a first temple and a second temple for supporting the waveguide assembly on a user's ears. ### Claim 19 (depends on 1) The adjustable waveguide assembly according to claim 1, wherein the at least one waveguide comprises a first lens and a second lens.
