Seeing the light. How does my eye work?

 
 
This is a fun question that people are often interested in. One of the most common analogies used is that of a camera. A camera can be thought of as having a focusing system (lens), a screen or sensor (film or digital sensor) and a storage component (film or digital sensor/memory). Similarly the eye has a focusing system (the cornea AND the lens), a sensor which is called the retina, and a system to transmit, process and store the images. This last component comprises a significant portion of the brain! Despite the amazing progress of digital cameras, your brain is still far ahead and is likely to remain ahead for some time
