The Ciliary Body is located
in each eye in the human body.
(Some animals have eyes structured in a very similar way to human eyes,
whereas some other animals have eyes that are structured and work in very
different ways.)
The ciliary body connects the choroid
with the iris,
and consists of three zones.
They are:
*_ The ciliary ring - which is attached to
the choroid,
*_ The ciliary
processes - which forms part of the attachment to the lens,
*_ The ciliary
muscle - which controls the curvature of the lens,
and therefore its accommodation to enable us to view both close and distant
objects according to where our vision is focused.
The subject of visual (also known as "physiological") optics
is a key component of many courses within the fields of both biology and
physics. It is also an essential consideration in the design of displays
and control units used in many applications from televisions and mobile
telephones to advanced aircraft. In the context of engineering "visual
optics" is one of several medical and psychological topics in the
important area of "Human Factors".
