The light continues to pass through the pupil, making it dilate and the image more focused. Moving towards the back of the eye, a layer that contains cells sensitive to light is called the retina. Cone and rod cells sit on the retinas outer layer and absorb distinct bundles of energy. Cones help one perceive color and detail, while rods show black, lights, and whites.
