Rod and cone cells are part of either retina or eye lens?

The rod and cone cells are part of a delicate membrane called the retina. Rods and cones are light-sensitive cells that respond to the intensity of light and colour of objects, respectively, by generating electrical signals.

Near the centre of the retina, there is an oval-shaped pigmented area, a little region about 5.5 millimetres in diameter that’s responsible for central vision, and is densely packed with photoreceptor cells called rods and cones that respond to light and also send electric nerve impulses into the optic nerve and to the mind. 

While the lens is a transparent bi-convex structure which is suspended behind the iris of the eye and functions to focus light rays onto the retina.
