Basic Eye Anatomy

Front

Eye

Back

The organ of sight that detects light and converts it into electro-chemical impulses in neurons.

Front

Retina

Back

The light-sensitive layer of tissue at the back of the inner eye that converts light images into nerve signals.

Front

Optic Nerve

Back

The nerve that transmits visual information from the retina to the brain.

Front

Rods

Back

Photoreceptors in the retina that are responsible for vision at low light levels.

Front

Cones

Back

Photoreceptors in the retina that are responsible for color vision and function best in relatively bright light.

Front

Photoreceptors

Back

Specialized cells in the retina that convert light into signals that can stimulate biological processes.

Rods and cones are photoreceptors.
