The term 'SITE OF RODS AND CONES' is referring to the RETINA, which is a light-sensitive layer of tissue that lines the inside of the eye. It contains two types of photoreceptor cells, rods and cones, which are responsible for converting light into electrical signals that are sent to the brain. These signals are then interpreted as images. The RETINA is essential for vision, and without it, we would not be able to see.
