You can purchase a set of binoculars based purely on their stats and hope that you get something that you enjoy. Or you can go to the store and pick them up, spin them around, see how they feel, and try to guess as to their quality. Or, you can keep reading and learn how to accurately evaluate a pair of binoculars for quality, fit, and overall suitability.

The first step is just to give it an overall visual inspection. How well does it look like it?s made? Does it feel solid, are any of the parts loose (that don?t seem like they should be), do any parts rattle or vibrate? Movement should be smooth and all of the pieces should feel as if they fit well together. Exercise all of the moving parts and check for anything unexpected.

Next you?ll want to inspect the main lenses, the objective lens. Ideally you should use a light to assist in your inspection, possibly a flashlight. Look deeply into the inside of the lenses, watching for any kind of blemish. This could be something as major and obvious as a scratch, but could also be dust or film or anything else. The lenses should appear absolutely perfect on the inside. You may need to move the binoculars around to get a good view into the deeper areas.

You should perform a similar inspection from the other end, where the eyepieces are. You won?t be able to get as good a view, of course, since the lenses are much smaller. You should also look through the binoculars. You should have a bright, clear, sharp image. Make sure that you are able to focus at various lengths, and that an independent focus on a single eyepiece can be adjusted for your vision. Also make sure that the two images (from each lens) line up to form a single image and do not leave you with double vision.

Do not get overly focused on just the center of your field of view. Validate that the edges do not bend or distort overly much, and that the majority of the view is clear and clean. It is only natural to have some minor degradation of quality at the very edges, but it shouldn?t be too noticeable and it shouldn?t extend very far in towards the center of the image.

Binoculars aren’t cheap. If you’re buying a nice pair, you can spend some good money. Like most people, you probably want to know that you’re getting a quality product for your money, so plan to spend some time getting to know the binoculars that you’re about to purchase. Don’t be afraid to play with them a bit and get comfortable before pulling out the credit card. After all, you wouldn’t buy a car without taking it out on the highway, right?

Whether you’re after the high power binoculars or best compact binoculars, test them thoroughly before you buy.

Binocular lens coatings are a common feature, but many people don?t particularly understand what they are, why they are needed, or what the descriptions of them mean when it comes to picking out a pair. They aren?t something you want to ignore though, as the coatings on your lenses can have a major effect on the overall viewing experience. Let?s examine the answers to each of these questions and see what that means for making a purchase decision.

Binoculars are made up of multiple different glass lenses arranged to direct light from the objective end (pointed at the subject) to the eye piece, where you are viewing the image. The unfortunate thing is that glass is not 100% perfect at transmitting light. Each glass surface will reflect some of the light that that strikes it, rather than passing it through.

As the image passes through each lens, this effect is additive and results in a significantly dimmer image reaching your eye than could otherwise be. Of course, you could simply graduate to larger objective lenses in order to compensate, but that will also increase the physical size and weight of the binoculars. A better solution is to simply increase the efficiency of the lenses that are already there.

That?s where binocular lens coatings come in. Lenses are coated with chemicals that reduce the light reflected, increasing the light that is allowed to pass through. Each one is a somewhat minor increase, but take altogether the light throughput can be increased by 50% or even more.

But the possibilities don?t end there ? it turns out that the coatings can be layered on top of each other. Each additional layer decreases the light reflection even more, which has led many manufacturers to coat their lenses multiple times, sometimes 10 or even more layers. This is applied to each lens in the binoculars, bringing the percentage of original light transmitted astonishingly close to 100.

The result is that you get the most possible light with the least hardware, the least bulk, and the least weight to cart around. Look at it as an efficiently play. Uncoated lenses are wasting a significant portion of the light coming in, and lens coatings simply reclaim that potential. Since this process adds virtually no weight, doesn?t have a detrimental effect on visibility, and vastly improves the brightness of an image, there?s no reason not to go for binoculars with lens coatings.

So don’t forget that whether you’re looking for high power binoculars or bausch & lomb binoculars, it’s important to understand what kind of lens coatings they offer. It can mean the difference between a so-so experience and a great one, an important distinction when you are spending good money on a pair of binoculars.
