Detailed explanation-1: -Retina: a light sensitive layer that lines the interior of the eye. It is composed of light sensitive cells known as rods and cones.
Detailed explanation-2: -The retina, which is the size of thumbnail, is filled with approximately 150 million light-sensitive cells. Two different types of receptors in the retina of each eye are responsible for the perception of fine detail and color (cones) and brightness (rods).
Detailed explanation-3: -Retina: The retina is the light-sensitive tissue at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve. Vitreous gel: The vitreous gel is a transparent, colorless mass that fills the rear two-thirds of the eyeball, between the lens and the retina.
Detailed explanation-4: -Rods and cones are the light-sensitive cells on the retina. Cones are sensitive to bright light and are capable of colour vision. Rods are sensitive to dim light and give twilight vision. They convert light waves into electrical impulses which are read by the brain.
