There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. ... Notice that the fovea is rod-free and has a very high density of cones

The retina has two types of cells that gather light: rods and cones.

The rods are around the outer ring of the retina and are active in dim light. Most forms of retinis pigmentosa affect the rods first. Your night vision and your ability to see to the side -- peripheral vision -- go away.

Cones are mostly in the center of your retina. They help you see color and fine detail. When retinis pigmentosa affects them, you slowly lose your central vision and your ability to see color.
