Abstract: A prescriptive see-through eyepiece includes a meniscus lens body and an optical combiner. The meniscus lens body has an external scene side with a convex curvature and an eye-ward side with a concave curvature. The optical combiner is disposed within the meniscus lens body to combine image light incident through the eye-ward side with external scene light incident through the external scene side into a combined image. The optical combiner is partially reflective and imparts substantially no lensing power to the external scene light passing through. The optical combiner along with the concave curvature of the eye-ward side are configured to impart prescriptive lensing to the image light while the convex curvature of the external scene side and the concave curvature of the eye-ward side are configured to impart the prescriptive lensing to the external scene light.

Abstract: A Head Mounted Display (“HMD”) includes a display module, an optical combiner, control circuitry, and a lens. The display module generates image light and the optical combiner is for combining the image light with external scene light. The lens is positioned to receive the image light. The lens is capable of dynamically changing at least one lens property of the lens. The control circuitry controls the lens to dynamically change at least one lens property of the lens.

Abstract: An optical apparatus includes a first optical element having an eye-ward facing surface and an external world facing surface substantially opposite of the eye-ward facing surface. The optical apparatus also includes a diffractive optical element (“DOE”) disposed to substantially follow a curvature of the eye-ward facing surface of the first optical element. The DOE includes a partially reflective diffraction grating configured to direct a portion of image light in an eye-ward direction where the image light is incident through an eye facing side of the DOE. The curvature of the eye-ward facing surface of the first optical element has an optical power configured to collimate the image light within an eyebox sized area.

Abstract: A Head Mounted Display (“HMD”) includes a display module to generate image light, an optical combiner, a stacked switchable lens, and control circuitry. The optical combiner combines the image light with external scene light. The optical combiner includes a reflective element coupled to receive the image light and direct the image light in an eye-ward direction. The stacked switchable lens is optically coupled to receive the image light. The stacked switchable lens includes at least a first switching optic and a second switching optic. The control circuitry is configured to selectively activate the first switching optic and the second switching optic. The first switching optic is configured to direct the image light toward a first eyeward region when activated by the control circuitry. The second switching optic is configured to direct the image light toward a second eyeward region when activated by the control circuitry.
