The use of binoculars help to expand your horizons by allowing you to see a distant object as if it
were located very close to your eyes. When viewing sporting events, for trips, hunting, bird watching,
hiking, boating concerts or theater, your binoculars will enhance your view of the world.
Some Helpful Notes About Your Binoculars
Your binoculars are marked with a set of numbers, 10 X 50. The first number represents the power
or magnification of the binoculars, while the second number represents the objective diameter
expressed in millimeters.
Magnification is defined as the amount of increase over the actual image size. A 7 x binoculars
magnifies the image by 7 times life size, while a 10 x binoculars gives a 10 times magnification.
For example, using 10 x binoculars, an object which is 100 feet away would appear to be only 10
feet away.
Objective Diameter:
The light gathering capabilities of binoculars are determined by the objective diameter. Binoculars
with large objective diameters (above 50 mm) are designed for low-light conditions and astronomical
use. Binoculars with small objective diameters (under 30 mm) are ideal in bright light. Binoculars
that fall in the range between (30-50 mm) represent a good compromise between light gathering
capability and size.
Field Of View:
The field of view is the extent of the area seen through the binoculars. It is expressed either in angular
measure or in feet/meters at a range of 1,000 yards/meters. Thus binoculars with a field of view of 358
feet/119 meters will show you about 358 feet / 119 meters at 1,000 yards/1,000 meters. The greater
the magnification, the less the field of view is.
The interpupillary distance of the eyes varies from 55 to 70 millimeters. The adjustment of the
Binoculars to your individual interpupillary distance is made by bending the bodies about their hinges,
thus increasing or reducing separation of the eyepieces until the two circular fields of view fuse into
It is a well-known optical phenomenon that under normal conditions, a loss of over 5% of light occurs on
passing through and air-to-glass surface. The coating on the lens surface of your binoculars eliminates
this loss and restores the light to the transmitted beam. The coating has two advantages:
a. The image of field of view is considerably brighter due to the increased transmission of light.
b. Contrast and definition are improved because of the almost complete elimination of stray light
reflected between the various lens surfaces.
Keep the rubber lens caps on the Binoculars and store in it’s carrying case when not in use. Use a
soft lens cleaning cloth with lens cleaning solution to clean the lenses. A good camera shop should
carry these items.

Using the Binoculars
Hold the Binoculars up to both eyes so that both are looking through the lenses. With one hand on
each of the barrels, move the barrels up or down to adjust the distance between them, until you are
seeing one complete and normal looking view through both the Binocular lenses-see Figure 1.
To focus the Binoculars, select an object about 25 feet away. Look through the lenses with both
eyes. Turn the Focus Wheel until the object appears in focus (see Figure 1).
