The eye is one of the five sensory organs, and it is responsible for sight and vision. The eyes are composed of the cornea, pupil, iris, lens, retina, optic nerve, and tear ducts.
The cornea is the front layer of the eye. It has the shape of a dome and works by bending the light entering the eye. The pupil is the black dot in the center of the eye that expands in dim light and shrinks in bright light.
The iris is the muscle that controls the size of the pupil and the amount of light that enters the eyes. The lens is behind the iris and pupil. It helps to focus the light that enters your eye together with the cornea. The lens brings the image to a sharp focus allowing you to see details.
The retina is a layer of tissue, and it transforms the light coming into the eye into electrical signals. These signals are sent to the brain by the optic nerve.
Tear ducts, even though rarely talked about, help to keep your eyes moist and protect your eyes from irritation and infection. Every part of the eye helps make you see. Therefore, your eyes should be treated with utmost care.
