The retina.
The retina is the reflective tissue at the back of the eye on which images are projected.
Cornea
the eye receives visual images from our surroundings, these images are received by the cones and rods which are on the retina which is found in the eye, the images are translated (by the cones and rods) and sent as impulses to the brain through the optic nerve, the brain is then able to inter-prate these impulses into images we see.
The cornea is the transparent front part of the eye that covers the iris, ... Because transparency is of prime importance the cornea does not have bloodvessels; it receives nutrients!
Retina
The "retina".
Well that depends. If you are referring to the eye on a whole, then the answer is no, the eye is considered part of the optical system. But if you mean "is any part of the eye consider to be part of the nervous system?", then the answer is yes, the optical nerve situated at the back of the retina, is part of the nervous system
The part of your eye that receives no blood at all is the cornea. This is the clear and transparent part of the eye and it does not have any blood vessels.
Your is a complex part of your body. It works the same as a camera lens it has different parts that focus and adjust. The main parts consist of the retina and the cornea. The cornea has the lenses and the retina receives the images.
This part is called a Lens, on the camera and the glasses the are made of either optical glass or optical plastic, in the eye the lens in an organic material. Lens allow light to enter the camera, eye or glasses, and focuses that light on a surface such as the camera's film, the eye's retina, and the glasses wearer's eyes.
