Rod cell
open-in-new
<p>Rod cells are <a href="/facts/Photoreceptor_cell/Ap0DcW5N">photoreceptor cells</a> in the <a href="/facts/Retina/v0ISNX2S">retina</a> of the eye that can function in lower <a href="/facts/Light/jeofpMn4">light</a> better than the other type of visual photoreceptor, <a href="/facts/Cone_cell/JoQeEzoF">cone cells</a>. Rods are usually found concentrated at the outer edges of the retina and are used in <a href="/facts/Peripheral_vision/r436lpjQ">peripheral vision</a>. On average, there are approximately 92 million rod cells (vs ~4.6 million cones) in the human retina. Rod cells are more sensitive than cone cells and are almost entirely responsible for <a href="/facts/Night_vision/tm6ToQgg">night vision</a>. However, rods have little role in <a href="/facts/Color_vision/j3ou3Izz">color vision</a>, which is the main reason why colors are much less apparent in dim light. </p>
