TermDefinition
Cornea The cornea is the clear, dome-shaped surface that covers the front of the eye. It helps focus light that enters the eye.
Retina The retina is a thin layer of tissue at the back of the eye that senses light and sends images to the brain through the optic nerve.
Lens The lens is a transparent structure behind the iris that changes shape to focus light on the retina for clear vision.
Iris The iris is the colored part of the eye that controls the size of the pupil, regulating how much light enters the eye.
Pupil The pupil is the black circular opening in the center of the iris that allows light to enter the eye.
Optic nerve The optic nerve carries visual information from the retina to the brain, where images are processed.
Eyelid The eyelid is a fold of skin that protects the eye, spreads tears, and helps keep the eye moist.
Tear duct The tear duct drains tears from the eye into the nose to keep the eye lubricated and clear of debris.
