Compare monoculars by price. When you shop for a monocular, you should look online at several models and brands to compare their prices. Take into consideration what you are looking for in terms of magnification power, the lens, the size, and the weight of the monocular. Try to compare several retailers online as well so you can get the best price for the monocular model you want.[13]
Some monoculars are filled with nitrogen to keep out hydrogen and oxygen, which can form condensation inside the device and cause rust. As long as the structural integrity of the device is intact, the nitrogen prevents internal fogging. Some cheap monoculars are not fog-proof. Internal fogging can be frustrating and might eventually cause damage. It's a question of balancing price against performance.
Depending on the focus type, binoculars can come either with an individual eyepiece focus or with a center focus. From what we’ve seen, individual focus binoculars provide excellent results in regards to medium and long distance work. When the user is visualizing the game beyond 30 to 40 yards, IF binoculars don’t even need any focusing at all, but that’s not the main reason they’re so popular among various types of buyers, including the military. In actuality, they are much easier to waterproof and have no external parts, therefore being a lot more durable.

These are great binoculars and we bought them for gifts, too. Even though they are sturdy, my son broke his first pair after about a year. He was running around the mall and trying out lawn mowers or something, and he threw them far across the building to divert my husband and me from the manhunt. I was able to put it together again but it seems like a precision instrument, so I bought another one for him recently. We'll use the repaired one as a toy and the new one for real adventures. We went to the beach yesterday to see seals out on the water, and my son was really thrilled with them. The manufacturer/vendor provides instructions about using the supplied strap for kids, but instead of that I bought a pack of wrist straps separately and we use a small wrist strap.
This is potentially the most important spec you will be looking at. Binoculars will have a number indicating their magnification power. The higher the number the better the distance they can view over or the more detailed the image will be. However, the more powerful the binoculars are the smaller the field of view will be; you will need to focus on specific points on the landscape.
^ Monocular individuals face increased challenges with driving. These specifically relate to depth perception and peripheral vision. Keeney, et al., state, "nationwide, monocularly impaired individuals have seven times more accidents than the general population with which they were compared." He recommends monocularly impaired drivers be denied class 1 licenses, (commercial driver license for transport of people), and that they be warned by their doctors regarding increased risk of accident with driving
When you want close-up views of distant objects, but have limited space for optical gear, a quality monocular is your best bet. Sometimes, a binocular or spotting scope is simply too large and cumbersome to bring along on family trips to the beach, sports games, or on camping excursions to scenic locations. The Orion 10x42 Waterproof Monocular is conveniently compact and portable, so you can enjoy magnified views of distant wildlife, birds, scenery, sporting events, and even the Moon without packing a lot of bulky equipment. What's more, its rugged, rubber-armored body and waterproof construction make the Orion 10x42 Monocular ideal for use in virtually any weather conditions. The Orion 10x42 Waterproof Monocular is advantageously small in size, but it provides big optical performance thanks to its 42mm aperture objective lens and quality BK-7 roof prism. All optical surfaces of the 10x42 Waterproof Monocular are fully multi-coated to ensure maximum light throughput so you can enjoy bright, vivid views, even in low-light conditions during dusk and pre-dawn hours. The monocular's wide 5.9 degree field of view provides a nicely sized window with 10x power magnification, so it's easy to track moving target objects during use. But what if that bird you're looking at decides to land on the very tree you're standing under? Not to worry -the Orion 10x42 Monocular features an amazing near focus distance of just 20-Inches - more than adequate for viewing even extremely close-by quarry with 10x power magnification. Eyeglass wearers will appreciate the Orion 10x42 Waterproof Monocular's comfortable, 17mm long eye relief, as it allows you to leave corrective lenses on during use. For those who don't wear glasses, or who prefer to remove them when using optical instruments, the 10x42 Monocular features a twist-up rubber eyeguard to help properly position your eye to take in the entire field of view comfortably.
A constant question I am asked is, “What’s the difference between nitrogen and argon?” A quick Google search will return many links to forums where people have very strong opinions on the matter and will get into any number of online arguments over the subject. The short answer is that, performance-wise, there really isn’t much of a difference between the two for the clear majority of people. Both gases will keep moisture out and prevent internal fogging. If you do a deep-dive into the chemistry and look at a diagram of each molecule, you will see that argon molecules are larger than nitrogen molecules. Because of this, some manufacturers feel the larger argon molecules will have a harder time leaking out from the seals, keeping the inert gas inside longer and thus maintaining their water/fog-proof properties over a longer period of time. From a practical standpoint, as long as you have an optic with either of these inert dry gases versus having none, you’re ahead of the game.

One of the features that make these binoculars impressive is the clarity you get, even when you view your surroundings with minimal ambient light. Things get even better once you switch on the IR illuminator. The quality is so good on the Pro Nexgen, you might find it hard believing that the device uses generation 1 technology. When the IR is off, you get more detail and less distance. The range is increased when IR is on although the quality tends to reduce. Since the binoculars work well without IR, you do not have to use your batteries all the time. According to the manufacturer, you can have up to 80 hours of battery life with the Nexgen. It’s important to note that the Pro Nexgen uses the CR123A battery type, which does not come cheap.
Another factor you must check is how a set of nighttime binoculars is powered. You want to choose one whose source of power is convenient for you and the battery life is long enough for your expeditions. A set that uses separate batteries means you can swap batteries if the current battery is depleted and continue with your observation but an onboard rechargeable battery is cost efficient in the long run. 

Peripheral vision – At the outer extremes of the visual field, parallel lines become curved, as in a photo taken through a fish-eye lens. This effect, although usually eliminated from both art and photos by the cropping or framing of a picture, greatly enhances the viewer's sense of being positioned within a real, three-dimensional space. (Classical perspective has no use for this "distortion", although in fact the "distortions" strictly obey optical laws and provide perfectly valid visual information, just as classical perspective does for the part of the field of vision that falls within its frame.)
