MAGNIFICATION
(POWER)
Binoculars are often referred to by two numbers separated with an "x".
For example; 8x32. The first number is the power or magnification of
the binocular. With an 8x32 binocular, the object being viewed appears
to be eight times closer than you would see it with the unaided eye.
OBJECTIVE
LENS SIZE
The second number in the formula (8x32) is the diameter of the
objective or front lens. The larger the objective lens, the more light
that enters the binocular, and the brighter the image.
