Terms to know

Cornea
The transparent part of the eye that covers the iris and the pupil and allows light to enter the inside.
Fovea
The center of the macula and gives the sharpest vision.
Iris
The colored tissue at the front of the eye that contains the pupil in the center. The iris helps control the size of the pupil to let more or less light into the eye.
Lens in the Eye
A clear disk that focuses light, as in a camera or microscope. In the eye, the lens is a clear, curved structure at the front of the eye behind the pupil. It focuses light rays that enter the eye through the pupil, making an image on the retina (light-sensitive layers of nerve tissue at the back of the eye).
Macula of the Eye
The part of the retina in the eye used for reading and seeing fine detail.
Optic Nerve
A bundle of more than 1 million nerve fibers that carries visual messages from the retina to the brain.
Peripheral Vision
Peripheral vision is a part of vision that occurs outside the very center of gaze. The loss of peripheral vision while retaining central vision is known as tunnel vision.
Retina
The light-sensitive tissue lining at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve.
