Aqueous humor - the clear, watery fluid inside the eye. It provides nutrients to the eye. Astigmatism - a condition in which the lens is warped, causing images not to focus properly on the retina. Binocular vision - the coordinated use of two eyes which gives the ability to see the world in three dimensions - 3D. Cones - cells the in the retina that sense color.

The inferior rectus: Attaches to the bottom of the eye and allows downward eye movement. The medial rectus: Attaches to the side of the eye adjacent to the nose and helps the eyes to shift inwards towards the nose. The lateral rectus: Attaches to the outer side of the eyes and moves the eyes toward the temples.

human eye, in humans, specialized sense organ capable of receiving visual images, which are then carried to the brain.. Anatomy of the visual apparatus Structures auxiliary to the eye The orbit. The eye is protected from mechanical injury by being enclosed in a socket, or orbit, which is made up of portions of several of the bones of the skull to form a four-sided pyramid, the apex of which.

Behind the anterior chamber is the eye's iris (the colored part of the eye) and the dark hole in the middle called the pupil. Muscles in the iris dilate (widen) or constrict (narrow) the pupil to control the amount of light reaching the back of the eye. Directly behind the pupil sits the lens. The lens focuses light toward the back of the eye.
Eye Anatomy
The main parts of the human eye are the cornea, iris, pupil, aqueous humor, lens, vitreous humor, retina, and optic nerve. Light enters the eye by passing through the transparent cornea and aqueous humor. The iris controls the size of the pupil, which is the opening that allows light to enter the lens. Light is focused by the lens and goes.

Structure of Human Eye. A human eye is roughly 2.3 cm in diameter and is almost a spherical ball filled with some fluid. It consists of the following parts: Sclera: It is the outer covering, a protective tough white layer called the sclera (white part of the eye). Cornea: The front transparent part of the sclera is called the cornea.

The iris is a flat, thin, ring-shaped structure sticking into the anterior chamber. This is the part that identifies a person's eye colour. The iris contains both circular muscles going around the pupil and radial muscles radiating toward the pupil. When the circular muscles contract, they make the pupil smaller.

The External Structure of an Eye. Sclera: It is a white visible portion. It is made up of dense connective tissue and protects the inner parts. Conjunctiva: It lines the sclera and is made up of stratified squamous epithelium. It keeps our eyes moist and clear and provides lubrication by secreting mucus and tears.
