Abstract
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.
