The human eye diagram displayed at right (click on it to see an enlarged image) shows all of the major features of human ocular anatomy. The eye has three layers or coats:
The space between the lens and cornea, not labeled in the figure, is called the ocular chamber. It is filled with a watery fluid, the aqueous humor, and divided by the iris into an anterior and posterior chamber (the latter, which is hard to see in the figure, lies between the lens and iris). The main cavity of the eye is filled with the jelly-like vitreous humor. The optic disc, commonly known as the "blind spot," is the point where the optic nerve enters the back of the eye. The suspensory ligament, also known as the zonula ciliaris, holds the lens, while the ciliary muscles control the iris.
