The at least one optics arm has first and second free ends that are removably connected to a second end of the central frame support at a point between the first and second free ends. The optics arm extends away from the central frame support and is configured to present information to the user via a display device. ## Claims ### Claim 1 An eyeglass optics side arm comprising: an optics temple having a first end; an optics pod having a first end and a second end; a display positioned on the first end of the optics pod; and a hinge assembly positioned at the first end of the optics temple, the hinge assembly including a first axis, the second end of the optics pod rotatably engaged with the hinge assembly, wherein the optics pod is configured to rotate about the first axis of the hinge assembly from a first folded position, where the second end of the optics pod is adjacent the first end of the optics temple, to a second elongated position, where the second end of the optics pod is at a distance away from the end of the optics temple greater than in the first position, wherein the optics pod is curved such that, in the first position, the optics temple is parallel with a portion of the optics pod and transverse to the display. ### Claim 2 (depends on 1) The eyeglass optics side arm of claim 1, wherein, in the first position, the end of the optics pod is in contact with the end of the optics temple. ### Claim 3 (depends on 1) The eyeglass optics side arm of claim 1, wherein the hinge assembly includes a first connection secured to the second end of the optics pod. ### Claim 4 (depends on 3) The eyeglass optics side arm of claim 3, wherein the hinge assembly includes a second connection secured to the end of the optics temple. ### Claim 5 (depends on 4) The eyeglass optics side arm of claim of claim 4, wherein the second connection is rotatably received within the first connection. ### Claim 6 (depends on 5) The eyeglass optics side arm of claim 5, further comprising a screw secured to the first connection, the screw being received within the first connection and the second connection. ### Claim 7 (depends on 1) The eyeglass optics side arm of claim 1, further comprising an image actuator assembly overlying the hinge assembly. ### Claim 8 (depends on 7) The eyeglass optics side arm of claim 7, wherein the image actuator assembly includes a spring and a button, the spring biasing the button away from the end of the hinge assembly along the first axis. ### Claim 9 A modular kit for an eyewear/head-mounted device assembly, the modular kit comprising: an eyeglass frame unit comprising a central frame support having first and second ends, and a connector extending from a first end of the central frame support; and an eyeglass optics side arm configured for removable connection to the connector mechanism and rotatably connected to the eyeglass frame unit, the eyeglass optics side arm comprising: an optics temple having a first end; an optics pod having a first end and a second end; a display positioned on the first end of the optics pod; and a hinge assembly positioned at the first end of the optics temple, the hinge assembly including a first axis, the second end of the optics pod rotatably engaged with the hinge assembly, wherein the optics pod is configured to rotate about the first axis of the hinge assembly from a first folded position, where the second end of the optics pod is adjacent the first end of the optics temple, to a second elongated position, where the second end of the optics pod is at a distance away from the end of the optics temple greater than in the first position, wherein the optics pod is curved such that, in the first position, the optics temple is parallel with a portion of the optics pod and transverse to the display. ### Claim 10 (depends on 9) The kit of claim 9, further comprising an image actuator assembly overlying the hinge assembly. ### Claim 11 (depends on 9) The kit of claim 9, wherein, in a first orientation, the connector is configured to overlie the hinge assembly and, in a second orientation, the connector is configured to be received within the hinge assembly along the first axis. ### Claim 12 (depends on 11) The kit of claim 11, wherein the eyeglass frame unit is configured to be rotated between a third position and a fourth position relative to the optics temple, and when the eyeglass frame unit moves from the third position to the fourth position, the connector moves relative to the optics temple and removably interlocks with the hinge assembly when the connector is received within the hinge assembly. ### Claim 13 (depends on 9) The kit of claim 9, wherein, in the first position the end of the optics pod is in contact with the end of the optics temple. ### Claim 14 (depends on 9) The kit of claim 9, wherein the hinge assembly includes a first connection secured to the second end of the optics pod. ### Claim 15 (depends on 14) The kit of claim 14, wherein the hinge assembly includes a second connection secured to the end of the optics temple. ### Claim 16 (depends on 15) The kit of claim 15, wherein the second connection is rotatably received within the first connection. ### Claim 17 Eyewear comprising: an eyeglass frame unit comprising a central frame support having first and second ends, and a connector extending from a first end of the central frame support; and an eyeglass optics side arm configured for removable connection to the connector mechanism and rotatably connected to the eyeglass frame unit, the eyeglass temple optics side arm comprising: an optics temple having a first end; an optics pod having a first end and a second end; a display positioned on the first end of the optics pod; a hinge assembly positioned at the first end of the optics temple, the hinge assembly including a first axis, the second end of the optics pod rotatably engaged with the hinge assembly, wherein the optics pod is configured to rotate about the first axis of the hinge assembly from a first folded position, where the second end of the optics pod is adjacent the first end of the optics temple, to a second elongated position, where the second end of the optics pod is at a distance away from the end of the optics temple greater than in the first position; and wherein the eyeglass frame unit is configured to be rotated between a third position and a fourth position relative to the optics temple, and when the eyeglass frame unit moves from the third position to the fourth position, the connector moves relative to the optics temple and removably interlocks with the hinge assembly. ### Claim 18 (depends on 17) The eyewear of claim 17, wherein, in the fourth position, the connector is received within the hinge assembly.
