To clearly see an object far away, the ciliary muscle is relaxed, which stretches the fibers connecting it with the lens, flattening the lens. Too much light being let in could damage the retina; too little light makes sight difficult. Further, synaptic convergence means that several rod cells are connected to a single bipolar cell. day) plays a major role in

The fovea is a dip in the retina directly opposite the lens, which is densely packed with cone cells.[14][17] Within the anterior segment and the posterior segment. Each sensor has its own lens and photosensitive cell(s).
