Lose your focus and some of life's finest opportunities can pass you by. This
hard-earned lesson drove the creation of Bushnell's PermaFocus binocular series.
Simply raise these 8x32 binoculars to your eyes and you'll catch the action
instantly with stunning clarity--no adjustments necessary. That's because of its
unique focus-free feature that keeps you dialed in for instantaneous viewing at
virtually any distance.
PermaFocus binoculars are perfect for sporting events, nature observation, and
winter days when gloves would hinder the use of standard-focus binoculars. The
8x32 binoculars offer other benefits as well, including fully-coated optics for
superior light transmission and brightness and a nonslip rubber armor that
absorbs shock while providing a firm grip.
Note: Focus-free models are designed for viewing distant
subjects. The close-focus limit is subjective and dependent on the user's
eyesight.
Magnification (Power)
Binoculars are often referred to by two numbers. For this example: 8x 32. The
first number is the power, or magnification, of the binocular. With an 8x 32
binocular, the object being viewed appears to be eight times closer than you
would see it with the unaided eye.
Objective Lens
The second number in the formula (8x 32mm) is the diameter of the objective or
front lens measured in millimeters. The larger the objective lens, the more
light that enters the binoculars and the brighter the image.
The binocular's unique focus-free feature lets you instantly
capture the action on the field. |

How Do the Bushnell® PermaFocus® Binoculars Work?
No focus mechanism or control is needed on PermaFocus because its point of focus
preset for optimal distant viewing only (and of course, most people buy
binoculars because they want a closer view of sports action, animals or other
subjects that are at least 50 or 100 feet away), and it takes advantage of
common "depth of field" principles.
The PermaFocus design takes advantage of the fact that the farther away the
subject is located, the less focusing adjustment is required to obtain an
acceptably sharp image. Try holding a pen a foot or so away from your eyes with
one hand, and a magazine page about a foot behind that with the other hand. Hold
these objects up against a distant background such as a wall at least 10 or 15
feet away. Focus your eye on the pen. The print on the magazine page just a foot
behind it will not appear sharp. If you shift your eye's focus to the page, the
pen in front will be quite blurry. Your eyes will not be able to focus sharply
on both objects at the same time. Move your point of focus to the wall, and both
the pen and the magazine will appear extremely out of focus, when they are in
your field of vision at the same time. Now try looking at two objects that are
separated by a greater distance (such as two trees 50-100 feet apart), but much
farther away. The farther away they are, the greater the distance between them
can be, yet both will still appear sharp to your eye. Using the same concept,
these binoculars can deliver a high quality view of the players, cheerleaders,
coach and goalpost located at different distances from you, because they are all
far enough away from you to take advantage of the unique PermaFocus optical
design.
