Visio problems: myopia, if you have difficultly seeing far away objects, but good vision for nearby objects. They are about 500 times more sensitive to light than are the cones, but they do not give rise to colour sensations: the cones, which are colour receptors, function best in bright illumination. In humans, rods and cones are found throughout the retina except in the fovea, a small area in the centre of retina that contains only cones. [type text: typically, many rods are connected to the same bipolar cell, where the additive effect of the many signals may be enough to fire it. 10min to reach their maximum sensitivity, while cones take approx.
