The eye is the organ with which we are able to see. Pictured here in front view with reddened conjunctiva (conjunctivitis). The eye consists of a lens system and specialized nerve cells that are responsible for the perception of light and color. The stimuli are passed through a cranial nerve (optic nerve) to the brain. The eye is richly supplied with vessels. In addition, muscles are attached to it, which are responsible for movement.
