    Abstract: Embodiments are described of an apparatus including an eyepiece having a front surface, a back surface spaced apart from the front surface, and an edge forming a perimeter of the eyepiece. The eyepiece includes an angled surface to direct light eye-measurement light reflected from an eye into the eyepiece and to direct display light out of the eyepiece to the eye. A first waveguide is formed in the eyepiece and extending from the angled surface to the edge, the first waveguide being optically coupled to a first portion of the angled surface having a first surface treatment. And a second waveguide is formed in the eyepiece and extending from the angled surface to the edge, the second waveguide being optically coupled to a second portion of the angled surface having a second surface treatment.

    Abstract: An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The light guide component includes an eye-ward facing surface, a world facing surface, and a recess disposed in the world facing surface in the viewing region. The recess has a recessed surface that is discontinuous with the world facing surface. An add-on component is disposed in the recess and has a first surface mated to the recessed surface and a second surface that forms a continuous outer surface with the world facing surface. A partially reflective layer is disposed along an interface between the recessed surface and the first surface of the add-on component.

    Abstract: An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location and emitting the display light at a viewing region. The light guide component includes an eye-ward facing surface having a reflection portion and a viewing portion, a folding surface oriented to reflect the display light received into the light guide component to the reflection portion of the eye-ward facing surface, and a first interface surface oriented to receive the display light reflected from the reflection portion of the eye-ward facing surface. A partially reflective layer is disposed on the first interface surface in the viewing region to reflect the display light through viewing portion of the eye-ward facing surface.

    Abstract: An eyepiece for a head wearable display includes a curved lightguide component, a curved see-through component, an output coupler, and a prescription layer. The curved lightguide component guides display light received at an input region and releases the display light along an eye-ward direction in a viewing region. 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 at least partially transmissive to ambient light incident through a world-facing side such that the viewing region is see-through. The curved see-through component is mated to the world-facing side of the curved lightguide component. The prescription layer has a first side mated to an eye-facing side of the curved lightguide component and a second side having a curvature that introduces prescriptive lensing to both the ambient light and the display light.

    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.
