The document lists 10 parts of the human eye and their functions: the pupil controls the amount of light entering the eye; the iris controls the size of the pupil; the cornea and crystalline lens focus light; the aqueous and vitreous humours maintain the shape and provide nutrients to the eye; the retina contains light-sensitive cells that detect light; the optic nerve carries visual signals to the brain; the ciliary muscles change the shape of the lens for focusing; and the sclera provides the eye's shape and protective outer coating.
