A system and method simplify a Head Mounted Display (HMD) design employing an array of individual Transparent Organic Light Emitting Diode (TOLED) (or similar transparent emitter) elements or a group of sub-elements between dual microlens (ML) elements to create a transparent visual display. The ML elements present both the ambient imagery and synthetic TOLED symbology at the user eye. The user side ML array presents the TOLED image at a defined distance (e.g., several feet to infinity) (to prevent near focus eye strain) and the ML array on the subject side of the transparent visual display enables presentation of the ambient scene to the user eye. A spherical topography ensures that the transparent visual display optical path is along the user eye line of sight to optimize optical throughput and image clarity. A pixel pitch of the transparent visual display determines the visual acuity of the overlay.
