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.

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.

Great Value
I have compared many binoculars before purchasing this pair and have no regrets what-so-ever. They are a great all-purpose binocular. The 7x magnification along with a larger 50mm aperture gives a very clear image, even indoors.
I regularly take them to hockey games and the wider field-of-view keeps the action in your sight.
The perma-focus keeps images sharp. Remember that they are set assuming you are looking through with at least almost 20/20 vision so you can not use them without corrective lenses.

I love these!
These binocs are very similar to the ones they replaced that cost 5x as much. The old ones got tossed because they were showing a double image after living in my backpack for 2 years or so. The Bushnells may or may not have the quality of optics that the more expensive units did but the "Permafocus" or infinite depth focus makes it so you just pick them up and look. If what you are looking at is further than about 75' away it will be clear. This is really great when multiple users are using them as you don't have to reconfigure them for each persons eyes. It is also good for scanning a wide area as you don't have to adjust focus for close or far. This also makes them great for watching sports where things move fast.
I decided to try these because we have some older 10x50 units that use the same "Permafocus" design under a different brand that got bought by Bushnell and they have been working great for over 10 years. I hope I will be able to say the same about these.

Good for brightly lit subjects if you're young, have 20-20 vision, and both eyes are the same
These things work by setting the focus to infinity and reducing the opening on the ocular (eye piece) side. That maximized the range of distances that are in focus and reduces the amount of light that gets in. The result is a slightly dimmed and more possibly in focus image. For noon-time football or other midday activities it's OK. Of indoor things like plays or evening activities, not so much.
If you wear eye glasses these won't work well. There is no way to hold them comfortably against your glasses.
If you eyes are different, as they are for most people, these won't work well. There is no way to individually adjust the separate eye pieces (as there is for all but the most least expensive :) binoculars.
If you are old, as I am, and need reading glasses, as I do, these won't work well. See the reasons above.
If none of these apply then you will probably find these a good value. Otherwise, search out binoculars with the functions you need and leave the magic to the magicians.
