Human eyeball is made up of three layers viz. 1) sclera, 2) choroid and 3) retina.

Anterior thin region of sclera is called cornea and the retina is the innermost layer of the eyeball.

The space present between cornea and lens is called aqueous chamber which contain thin watery fluid called aqueous humor.

The space present between lens and retina is called vitreous chamber which contain transparent gelatinous fluid called vitreous humor.

The aqueous humor and the vitreous humor maintain the shape of the eyeball.enlightened
