Abstract: An eyepiece for a head wearable display includes a curved lightguide component, an input coupler, and an output coupler. The curved lightguide component guides display light received at an input region peripherally located from a viewing region and emits the display light along an eye-ward direction in the viewing region. The curved lightguide component includes an eye-ward facing surface that is concave and a world facing surface that is convex. The input coupler is disposed at the input region to couple the display light into the curved lightguide component. The output coupler is disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide component. The output coupler is partially transmissive to ambient light incident through the world facing surface. The display light is guided between the input coupler and the output coupler entirely by total internal reflection.

Abstract: An eyepiece for a head wearable display includes a first lens body having a first interface side in which a first recess is disposed and a second lens body having a second interface side in which a second recess is disposed. 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.
