A wearable ophthalmic device is disclosed. The device may include an outward facing head-mounted light field camera (e.g., 16) 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 (e.g., 76) to access the numerical light field image data, and to computationally introduce an amount of optical power to the numerical light field image data based on the viewing distance from the user to an object to generate modified numerical light field image data. The device may also include a head-mounted light field display (e.g., 62) to generate a physical light field corresponding to the modified numerical light field image data.
