Rods

Summary Information: Rods

Rods: Rods are specialized visual receptors located in the retina of the eye. Rods detect light, but not color, and are vital to seeing in dim light or at night. Rods are more concentrated along the edges of the retina than in the center area.

Light flows through the cornea and the pupil onto the lens before it is projected onto the rods on the retina. The rods then transform light into electrical impulses that can be transmitted by the ganglion neurons, which make up the optic nerve, to the nervous system. Conditions that can afflict the rods include vitamin A deficiency and night blindness.
