The central part of the retina, the Fovea, is composed only of cone cells. Anything that needs to be examined in detail is automatically brought to focus on the fovea. The rest of the retina fulfils the function of attracting our attention to movement and change. This is termed as Central Vision. As light decreases, the sensing task is passed over from the cones to the rods.
