The eye is an amazing and complex organ.  The more we learn about it, the more we realize its complexity.  It is easiest to understand, however, if you think of it as a camera.  Even its anatomy is somewhat similar. 

    • Both the camera and the eye have a lens or lens system 
    • Both provide a way to collect incoming light 
    • Both provide an image that must be interpreted by  the brain.

A brief sketch of specific structures of the eye can be found in the above menu.  Each of these structures, when diseased, gives rise to problems, depending on their anatomic location and function. Understanding the basic anatomy and physiology of the eye is key in understanding vision problems and their treatment.
