Artificial Retina: The Race to Help the Blind SeeArgonne, Lawrence Livermore,Oak Ridge, Universities Pool Research in Artficial RetinaLight coming into the eye falls upon a photosensitive area at the back of the eye called the retina. The retina does the heavy lifting of converting the light into signals that the brain uses in order to see. The retina in the eye is somewhat analagous to the CCD in a digital camera where the light focused by the lens falls on the pixels of the CCD.
An artificial retina for blind persons would theoretically enable many blind people to see again. Several national labs and universities have formed an association to coordinate their work on the artificial retina. Argonne near Chicago is contributing it’s ultrananocrystalline diamond technology to make biocompatible implants. Lawrence Livermore, Los Alamos, Oak Ridge Labs as well as the University of California, USC and North Carolina State are in the partnership.
