Artificial Vision

Artificial vision refers to the technology (usually, visual implants) that allows blind people to see. The main aim of visual implants is to relay the picture to the brain using either cameras or photoreceptor arrays. There are different types of implants used to stimulate vision; retinal, cortical, optic nerve, and biohybrid implants. None of the currently available technologies restores full vision, but they are often able to improve one's ability to recognize shapes and movements.
