An artificial retinal system includes an external optical device having an image generator and a background light generator, and a retinal implant chip having a solar cell and a stimulus generator. The stimulus generator is disposed to receive a target image projected by the image generator and a background light provided by the background light generator, and receives the electrical power from the solar cell. The stimulus generator includes an image sensing stimulator operable to convert the target image into electrical stimuli, and a contrast enhancer for reducing effect of the background light on the electrical stimuli.

An optical aid comprises a projecting device and a retinal implant device. The projecting device includes an image projector for outputting a projected image and a light generator for emitting an auxiliary light that differs in wavelength from the projected image. The retinal implant device includes an optical-to-electrical converter and an image sensor. The optical-to-electrical converter converts the auxiliary light received thereby into electricity for powering the image sensor. The image sensor is disposed in such a way that the auxiliary light is not received thereby, and generates an electrical stimulus signal associated with the projected image.
