Abstract
A wearable ophthalmic device is disclosed. The device may include an outward facing head-mounted light field camera to receive light from a user's surroundings and to generate numerical light field image data. The device may also include a light field processor to access the numerical light field image data, to obtain an optical prescription for an eye of the user, and to computationally introduce an amount of positive or negative optical power to the numerical light field image data based on the optical prescription to generate modified numerical light field image data. The device may also include a head-mounted light field display to generate a physical light field corresponding to the modified numerical light field image data.
