Hint: Eye is the important organ for the survival of all the organisms that provide vision. The image taken from the eyes is transported to the brain as the nerve impulse by the sensory neurons and the image perception or the processing takes place.
Complete answer:
The eye has numerous parts that must cooperate so as to deliver clear vision. Retina is the same as the film of the camera and hence they are called the film of the eye. Their main function of the retina is to receive the image and convert it into the electrical impulse. The retina is composed of ten layers of cells that cooperate to recognize light and transform it into electrical driving forces. These unique cells are called cones and rods and are known as photoreceptors.
Cones:
Cones are situated in the focal, or macula, part of the retina. These cells help recognize shading and bright areas. Additionally, the macula permits us to perform fine capacities like writing, reading and plainly perceiving individuals' facial differences (e.g., spots).
Rods:
Poles are situated in the fringe or external, part of the retina. These cells permit us to see in the poor lighting and furnish us with night vision.
Note: The layer of the retina has the blind spot in it. It is the area which has the optical neurons and this helps in the transferring of the image into the electrical impulses to the brain. In the brain, the visual recognition of an image takes place.
