The human eye is the second most complex organ in the human body after the brain. Although the eye is only the size of a ping-pong ball, it has 2,000,000 working parts! To understand how the eye works, we first need to understand the main parts of the eye. This is the anatomy of the eye.

The eyeball is a spherical structure, about 2.5 centimetres (1 inch) in diameter, located in a protective, conical cavity inside the skull called the orbit or socket.

The thick, white outer layer of the eyeball is called the sclera.

The front surface of the eye has a bulge called the cornea.

The space behind the cornea is filled with a clear fluid called aqueous.

Behind the cornea is the iris. The iris is a coloured area with a hole in the centre called the pupil.

Behind the iris and pupil is the lens.

The light-sensitive layer inside the eye is called the retina. The retina is covered by optic rod cells and cone cells.

The inside of the eyeball is filled with vitreous humor.

The optic nerve is a bundle of nerve fibres in the back of the eyeball that leads to the brain. Six muscles surround the eyeball and help it move.
