Abstract
A head-mounted device may have a head-mounted support structure with a left side portion, a right side portion, and a transparent front portion forming a lens. The lens may extend across the front of a user's face between the left and right side portions. The lens may have a mirror coating or other optical coating that helps obscure objects on the inner side of the lens when viewed from an exterior region surrounding the head-mounted device. Left and right forward-facing cameras with overlapping fields of view may be used to capture visible-light images through the lens. The cameras may also be used for gaze tracking. Left and right light sources may provide eye illumination that reflects from the lens into left and right eye boxes. Images from the eye boxes may reflect from the lens towards the left and right forward-facing cameras.
