Introduction
Vision is a biological phenomenon in which electromagnetic radiation interacts with specialized cells that when stimulated cause a chemical change. This chemical change starts a cascade of neurological events resulting in perception of the organism's external environment. The majority of this website focuses on the human retina, the part of the eye that interacts with electromagnetic radiation and sends information to the brain for further processing. In addition you will find basic information about research into the development of an artificial retina in the future.
