How the amazing eye works

1. 
   A miniature camera is housed in Ray Flynn’s spectacles, records images of what is in front of him. The video data is sent to a small computer processor, which transforms the images into electrical impulses.
   
2. 
   The impulses are then transferred wirelessly to a tiny antenna implanted on the side of the eyeball.
   
3. 
   They are sent via a short cable to the electrodes on the surface of the retina.
   
4. 
   The electrodes stimulate the cells on the retina, creating a perception of patterns of light in the brain. The patient then learns to interpret these visual patterns as rough images
