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.

Abstract: A method of in-eye icon projection using an electronic device includes emitting light with a light source in response to detecting an image condition. The light is then projected onto a diffraction grating, and the diffraction grating, when illuminated with the light, produces image light of a fixed icon. An image of the fixed icon is formed in an eye of a user, and the image of the fixed icon occupies only part of the user's field of view. The image light has a limited divergence such that the image of the fixed icon is only viewable in a single user's field of view.

Abstract: An optical combiner includes an off-axis spatially multiplexed lens optically coupled to receive image light and direct the image light in an eye-ward direction. The off-axis spatially multiplexed lens includes a first sub-lens multiplexed with a second sub-lens. The first sub-lens and the sub-lens are configured to direct the image light to designated eyeward-regions.

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 an optical combiner, an image lens, and an external scene lens. The optical combiner has an eye-ward side and an external scene side and includes a partially reflective diffraction grating that is at least partially reflective to image light incident through the eye-ward side and at least partially transmissive to external scene light incident through the external scene side. A first mount is positioned to hold the image lens in an optical path of the image light to apply a first corrective prescription to the image light. A second mount is positioned to hold an external scene lens over the external scene side of the optical combiner to apply a second corrective prescription to the external scene light. The optical combiner combines the image light with the scene light to form a combined image that is corrected according to the first and second corrective prescriptions.
