The first and second lens bodies are mated together along the first and second interface sides and the first and second recesses are aligned to form a cavity. A lightguide insert is provided that has a shape and a size to fit within the cavity defined by the first and second recesses. The lightguide insert includes an in-coupling region to receive display light into the lightguide insert and an out-coupling region to direct the display light out of the lightguide insert through the first lens body.
