Abstract
A visual prosthesis apparatus and a method for providing artificial vision are disclosed in the present disclosure. The visual prosthesis apparatus comprises a camera for capturing a video image, a video processing unit configured to convert the video image to stimulation patterns, and a retinal stimulation system configured stimulate neural tissue in a subjects eye based on the stimulation patterns. An artificial vision may be provided by capturing a video image, converting the video image to stimulation patterns, and stimulating neural tissue in a subjects eye based on the stimulation patterns.
