Eyeball

The eyeball is the main structure of the eye that contains the optical elements, including the cornea, lens, and iris. The eye also has eyelids, tear glands, conjunctiva, and other structures that help maintain healthy eyes and vision. The eyeball is the most important sense organ and plays a key role in perceiving the world around us through vision.

From an anatomical point of view, the eye has three layers: the anterior one, called the sclera, the middle one, called the choroid, and the posterior one, called the retina. The back of the eyeball is divided into two parts by a septum called the choroid.
