The eye is 3 аnаtоmic lаyers, and essentially an extensiоn оf the brain. The white part of your eye is actually the of the brain/central nervous system. The inner layer of the eye is made of rod and cone neurons, physically pressed against the outer shell of the eye by a gel-like structure called the . The eye works by bending light and focusing it onto a very small point/pit at the very back of the eye. Within this pit, the eye places almost all of the neurons and this is also the most sensitive area of the eye, where your finest visual ability is found. This pit is called the . The structure of the eye that bends/refracts light is called the , and is covered by lacrimal fluid/tears. The structure that focuses light is called the , and this structure's thickness (hence focus) is controlled by a smooth muscle ring, controlled by the autonomic nervous system.
