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 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.

Abstract: An optical device includes variable optical material that alters at least one of: incident ambient light, spectral content of incident ambient light or direction of incident ambient light through the optical device in response to a stimulus provided by the device. The device can sense intensity and/or spectral characteristics of ambient light and provide appropriate stimulus to various portions of the optical device to activate the variable optical material and alter at least one of: incident ambient light, spectral content of incident ambient light or direction of incident ambient light.
