![]() Rods function mainly in dim light and provide monochromatic vision. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rods and cones. The neural retina consists of several layers of neurons interconnected by synapses and is supported by an outer layer of pigmented epithelial cells. ![]() The retina serves a function which is in many ways analogous to that of the film or image sensor in a camera. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. ![]() The retina (from Latin: rete "net") is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs.
