The structure includes a frame that defines a display lens area and a free lens area, where the structure is wearable to position the display lens area across from a first eye of a user and the free lens area across from a second eye of the user. The display assembly includes a display surface provided in the display lens area. The panel attenuates light provided in the free lens area. ## Claims ### Claim 1 An electronic eyewear device comprising: a structure including a frame that defines a display lens area and a free lens area, the structure being wearable to position the display lens area across from a first eye of a user and the free lens area across from a second eye of the user; a display assembly including a display surface provided in the display lens area; and a panel to attenuate light provided in the free lens area, wherein a position of the panel with respect to the free lens area matches a position of the display surface with respect to the display lens area. ### Claim 2 (depends on 1) The electronic eyewear device of claim 1, wherein the display assembly renders an output including an image on the display surface that appears superimposed on a surrounding environment of the first eye. ### Claim 3 (depends on 1) The electronic eyewear device of claim 1, wherein an interior façade of the panel that directly opposes the second eye is opaque. ### Claim 4 (depends on 3) The electronic eyewear device of claim 3, wherein an exterior façade of the panel includes a visual design different from the interior façade of the panel. ### Claim 5 (depends on 1) The electronic eyewear device of claim 1, wherein the panel includes a material that changes opacity in response to an input. ### Claim 6 (depends on 5) The electronic eyewear device of claim 5, wherein the material is electrochromic. ### Claim 7 (depends on 1) The electronic eyewear device of claim 1, wherein the panel is physically manipulatable in orientation. ### Claim 8 (depends on 1) The electronic eyewear device of claim 1, wherein the panel obscures of a same portion of a field of view of the second eye of the user that is viewed through the display surface by the first eye of the user. ### Claim 9 (depends on 1) The electronic eyewear device of claim 1, wherein a size of the panel matches a size of the display surface. ### Claim 10 (depends on 9) The electronic eyewear device of claim 9, wherein both the panel and the display surface occupy only a portion and less than all of the free lens area and display lens area, respectively. ### Claim 11 (depends on 1) The electronic eyewear device of claim 1, wherein the panel is attached to the frame by a pivot, hinge or slider to allow the panel to move into and out of position in the free lens area. ### Claim 12 An accessory device for an electronic eyewear device, the electronic eyewear device comprising a display device to be positioned in front of first eye to display an image that then appears superimposed on a field of view as partially seen through the display device, the accessory device comprising: a panel formed of material to attenuate light; and a coupling mechanism to couple the panel to a structure of the electronic eyewear device to position the panel in a lens area of the structure corresponding to a second eye, the panel to attenuate light from a same area of the field of view over which the displayed image is superimposed. ### Claim 13 (depends on 12) The accessory device of claim 12, wherein an interior façade of the panel is opaque. ### Claim 14 (depends on 13) The accessory device of claim 13, wherein an exterior façade of the panel includes a visual design different from the interior façade of the panel. ### Claim 15 (depends on 12) The accessory device of claim 12, wherein the panel includes a material that changes opacity in response to an input. ### Claim 16 (depends on 15) The accessory device of claim 15, wherein the material is electrochromic. ### Claim 17 (depends on 12) The accessory device of claim 12, wherein the panel is physically manipulatable in orientation relative to the lens area of the structure. ### Claim 18 (depends on 12) The accessory device of claim 12, wherein the panel can be integrated with an eyeglass of the structure. ### Claim 19 (depends on 12) The accessory device of claim 12, wherein the coupling mechanism is a snap, clamp or magnetic coupling mechanism. ### Claim 20 An electronic eyewear assembly, the electronic eyewear assembly comprising: an eyewear device including a first lens and a second lens; a display component coupled to the eyewear device to generate display content on a display surface positioned on an interior of the first lens; and a panel coupled to the eyewear device to attenuate light directed through an exterior of the second lens, the panel corresponding to the display surface in size and in position relative to each respective lens.
