Abstract: A wearable ophthalmic device may include a head-mounted light field display configured to generate a physical light field comprising a beam of light. Camera(s) on or in communication with the device may receive light from the surroundings, and a light field processor may determine, based on the light, left and right numerical light field image data describing image(s) to be displayed to the left and right eyes respectively. The left and/or right numerical light field image data can be modified to computationally introduce a shift based on a determined convergence point of the eyes, and the physical light field presented to the user can be generated corresponding to the modified numerical light field image data, e.g., to correct for a convergence deficiency of the eye(s).

Abstract: A virtual image generation system comprises a planar optical waveguide having opposing first and second faces, an in-coupling (IC) element configured for optically coupling a collimated light beam from an image projection assembly into the planar optical waveguide as an in-coupled light beam, a first orthogonal pupil expansion (OPE) element associated with the first face of the planar optical waveguide for splitting the in-coupled light beam into a first set of orthogonal light beamlets, a second orthogonal pupil expansion (OPE) element associated with the second face of the planar optical waveguide for splitting the in-coupled light beam into a second set of orthogonal light beamlets, and an exit pupil expansion (EPE) element associated with the planar optical waveguide for splitting the first and second sets of orthogonal light beamlets into an array of out-coupled light beamlets that exit the planar optical waveguide.

Abstract: A wearable ophthalmic device is disclosed. The device may include a head-mounted light field display configured to generate a physical light field comprising a beam of light. The head-mounted light field display may direct the beam of light into a user's eye, thereby producing a retinal reflex. The device may also include a head-mounted photodetector array configured to receive the retinal reflex and to generate numerical image data. The device may also include a light field processor configured to control the light field display, to analyze the retinal reflex using the numerical image data, and to determine an optical prescription for the user's eye based on the analysis of the retinal reflex.
