Bushnell 8 x 32 Permafocus Binocular: Sports & Outdoors. 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. 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.

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 inch 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. The farther away they are, the greater the distance between them can be, yet both will still appear sharp to your eye.
