The cornea is the transparent membrane that acts as the window to the eyes, bending or refracting light to help the eye focus.
The iris is the colored part of the eye, which opens and closes to control entering light.
The pupil is the black opening at the center of the iris through which light passes.
The aqueous humor is the clear, watery fluid that fills the space between the cornea and the lens, providing nutrition to the surrounding parts.
The lens is a transparent, elastic elliptical structure that bends light rays, helping the eye focus for seeing up close and far away.
The vitreous humor is the clear, jelly-like fluid that fills the back portion of the eye.
The retina is the lining at the back of the eye that contains layers of light-sensitive nerve cells called rods and cones.
The optic nerve is the bundle of nerve fibers that carries electrical signals from the retina to the brain.
