What are the parts of the eye and their function?

The human eye works by sending light through a series of specialized parts to the optic nerve directly to the brain. Light-processing parts include the cornea, pupil, crystalline lens, retina, and finally the optic nerve itself. Each part of the eye has a specific task to help the brain receive signals that it can translate into usable visual input.

What is the path of light through the eye?

Light enters via the clear cornea of the eye. Its intensity is controlled by the adjustable diaphragm, the iris. The light passes through the iris opening called the pupil, and is focused by the lens on the retina.

What is the normal anatomy of the eye?

The anatomy of the eyeball in humans includes a round pupil, though the pupil may be square or elliptical in other animals. Once light enters the eye, it forms an upside-down image on the back of the interior of the eyeball, the retina.

What is the function of the eye?

Eyes are organs of the visual system. They provide animals with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision.
