The Aqueous Humour is
located at the front of each eye in the human body.
Note that this is spelt "Aqueous Humor" in textbooks that use American
spellings - the meaning is the same.
The aqueous humour is a watery fluid that fills the
chamber called the "anterior chamber
of the eye" which is located immediately behind the cornea and
in front of the lens - click
for diagram, and also the "posterior chamber of the eye" which is
a very narrow compartment located between the peripheral part of the iris,
the suspensory ligament of the lens, and the ciliary
processes.
The aqueous humour is very slightly alkaline salt solution that includes
tiny quantities of sodium and chloride ions.
It is continually produced, mainly by the capillaries of
the ciliary
processes, and drains away into Schlemm's canal, located at the
junction of the cornea and the sclera.
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".
