Retina: The retina is the nerve layer that lines the back of the eye, senses light, and creates impulses that travel through the optic nerve to the brain. There is a small area, called the macula, in the retina that contains special light-sensitive cells. The macula allows us to see fine details clearly.

Third eye is the extension of what the mind knowingly perceives. It is the subconsious awareness of the surroundings and interactions of the environment.
