Answer
The innermost coating of the eye, covering the rear of inner surface is the retina. It is the screen on which the image is formed by the eye lens. Retina contains a large number of nerve fibres and blood vessels and act as a light sensitive screen to receive the images. The light sensitive cells get activated upon illumination and generate electrical signals. The sensation of vision in the retina is carried to the brain by optic nerve fibres, which are more than one million.
