Key Takeaways: The Human Eye and Vision The main parts of the human eye are the cornea, iris, pupil, aqueous humor, lens, vitreous humor, retina, and optic nerve. It is mostly water and gives the eye its form and shape. The cornea and lens of the eye are analogous to the camera lens, while the retina of the eye is like the film. Vitreous Gel: A thick, transparent liquid that fills the center of the eye. It contains millions of photoreceptors (rods and cones) that convert light rays into electrical impulses that are relayed to the brain via the optic nerve. Retina: Light-sensitive tissue that lines the back of the eye. ![]() It changes size as the amount of light changes. Pupil: The opening in the center of the iris. Optic Nerve: The nerve that transmits electrical impulses from the retina to the brain. Retinal Detachment vector illustration diagram, anatomical scheme. Macula: The small area at the center of the retina responsible for what we see straight in front of us. Structure of the human eye and organization of the retina. Lens: A crystalline structure located just behind the iris – it focuses light onto the retina. Iris: The colored part of the eye that controls the amount of light that enters the eye by changing the size of the pupil. Nutrition of the eye is dependent upon blood vessels in the choroid.Ĭiliary Body: the part of the eye that connects the iris to the choroid.Ĭornea: The clear, dome-shaped tissue covering the front of the eye.įovea: A tiny pit located in the macula of the retina that provides the clearest vision of all. Let’s look at a few of the main parts of this vital organ:Īnterior Chamber: The space between the cornea and the iris, filled with the aqueous humor.Ĭhoroid: The vascular layer of the eye, containing connective tissue. It is made up of many distinct parts working in unison together and in order for the eye to work at its best, all parts must work well collectively.

While it may be tempting to believe that the visual pathway begins at the cornea (where light first makes contact with the eye), the actual pathway begins at the retina. ![]() ![]() The human eye has several structures that enable entering light energy to be converted to electrochemical energy.
