Optical Magnifying Glass
The magnification
of a magnifying glass depends upon where it is placed between the
user's eye and the object being viewed, and the total distance
between them. The magnifying power is equivalent to angular
magnification (this should not be confused with optical power,
which is a different quantity). The magnifying power is the ratio
of the sizes of the images formed on the user's retina with and
without the lens.
