E.E.X
The thin, transparent membrane that covers the white part of the eye (sclera) and the inner surface of the eyelids. It helps to lubricate the eye and protect it from foreign particles?
Conjunctiva
The white, outer layer of the eye that provides structural support and protection for the eye?
Sclera
The clear, dome-shaped outer layer of the eye that helps to focus light and protect the eye from damage?
Cornea
The colored part of the eye that controls the size of the pupil and regulates the amount of light entering the eye.
Iris
The black, circular opening in the center of the iris that allows light to enter the eye.
Pupil
The clear, flexible structure located behind the iris that helps to focus light onto the retina.
Lens
The ring-shaped muscle that surrounds the lens and helps to control its shape.
Ciliary body
The fibers that attach the ciliary body to the lens and help to hold it in place.
Suspensory ligament
The light-sensitive layer of tissue at the back of the eye that contains photoreceptor cells (rods and cones) that convert light into electrical signals.
Retina
The small, oval-shaped area near the center of the retina that contains a high concentration of cones and is responsible for central vision.
Macula
The small, central pit within the macula that contains only cones and is responsible for sharp, detailed vision.
Fovea
The nerve that carries visual information from the retina to the brain.
Optic nerve
The layer of tissue between the retina and the sclera that contains blood vessels that supply oxygen and nutrients to the eye.
Choroid
The clear, watery fluid that fills the space between the cornea and the lens and helps to nourish the cornea and lens.
Aqueous humor
The drainage channel located in the eye’s anterior chamber that helps to regulate the pressure inside the eye.
