The optic nerve consists of up to approx. The blind spot is next to the macula, where the optic nerve exits the eye. In contrast, the rods are located more toward the periphery of the retina. Cones in great numbers are concentrated at the centre of the retina, at the point of clearest vision (also referred to as the macula). The rods are responsible for vision at low light levels, while the cones are responsible for colour vision. It is made up of millions of light-sensitive neurons, known as rods and cones.
