The entire staff of Family Eye Care of Elmwood Park wants to share this educational video on the anatomy of your eyes in hopes that it will provide our patients with a better understanding or the importance of having routine eye exams. Comprehensive eye exams are the best way to keep your eyes healthy and your vision intact. Watch the introduction to the eye video to learn more!
Our eyes allow us to appreciate the beauty of the world, experience the joy of learning new activities, and undertake new adventures. Knowing the anatomy of your eyes and having regular examination is the best way to keep your eyes healthy and your vision intact.
The sclera, also known as the white part of the eye, is the opaque, fibrous, protective outer layer. The pupil is the hole located in the center of the iris that allows light to enter the eye. It appears black because the light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffused reflections within the eye that mostly miss exiting the narrow pupil. The iris is a thin, circular structure in the eye responsible for controlling the diameter and size of the pupil. The color of the iris is often referred to as eye color.
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea with the anterior chamber and lens refracts light with the cornea accounting for approximately two-thirds of the eye’s total optical power.
The crystalline lens is a transparent, biconvex structure that, along with the cornea, helps to refract light to be focused on the retina. By changing shape, the lens functions to change the focal distance of the eye so it can focus on objects at various distances.
The retina is a light-sensitive layer of tissue lining the surface of the eye. It captures light sent through the cornea and crystalline lens to create an image by triggering nerve impulses that pass to various visual centers of the brain via the optic nerve. The macula and fovea are small f areas within the retina that contain rods and cones to determine the color and shape of the image you are viewing.
