The modules will be linked to retinal nerves that will send electrical impulses to the brain for processing.
Diseases such as age-related macular degeneration and retinitis pigmentosa damage the rods and cones in the eye that normally convert light to electrical impulses, but leave intact the nerve pathways to the brain.
