Abstract: An eyepiece includes a first lens body having a first interface side and a second lens body having a second interface side. At least one of the first and second interface sides includes a recess. The first and second lens bodies are mated together along the first and second interface sides to form a cavity at the recess. A lightguide insert is provided that has a shape and a size to fit within the cavity. 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.
