Abstract
In embodiments of eyebox adjustment for interpupillary distance, a first optical lens receives light of an image from a display optic at a projected orientation of the light, and the first optical lens deviates the light of the image by a deviation angle from the projected orientation of the light. A second optical lens receives the light of the image from the first optical lens at the deviation angle, and the second optical lens alters the deviated light of the image back to the projected orientation of the light for viewing the image. Left and right eyeboxes align with respective left and right eyes that view the image, and a distance between the left and right eyeboxes approximately correlates to an interpupillary distance between the left and right eyes. The light of the image can be laterally shifted to increase or decrease the distance between the left and right eyeboxes.
