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 initially number is the power, or magnification, of the binocular. With an 8x 32 binocular, the object being viewed appears to be eight era quicker 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 quicker 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 grow 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. Go your point of focus to the wall, and both the pen and the magazine will grow 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 grow sharp to your eye. Using the same thought, 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.
