Vision is the sense most relied upon by humans. While most of us take sight for granted, it is the result of very
complex reactions. Light strikes the eye, setting off a series of electrochemical reactions within the eye. These reactions are interpreted by the brain,
creating the images that we see. There is a lot about sight that we do not yet
understand, however research is uncovering more and more about how the eye
works. By knowing how the eye operates, there are many fun and interesting
effects that can be observed.
This section focuses on how the optical
system creates the images that we see around us. Topics include the construction
of the eye and the workings of the optical center of the brain.
