'''Rod cells''' are [[photoreceptor cell]]s in the [[retina]] of the eye that can function in lower [[light]] better than the other type of visual photoreceptor, [[cone cell]]s.  Rods are usually found concentrated at the outer edges of the retina and are used in [[peripheral vision]]. On average, there are approximately 92 million rod cells (vs ~4.6 million cones) in the human retina.<ref>{{cite journal | last1 = Curcio | first1 = C. A. | last2 = Sloan | first2 = K.

However, rods have little role in [[color vision]], which is the main reason why colors are much less apparent in dim light.
