What is a Monocular and What is it Used For?

A monocular is an optical device similar to binoculars in functioning. The tool, however, requires one eye for viewing distant objects clearer. It is essentially a telescope that refracts light by its passage through various lenses and prisms. However, it is more compact and lighter in weight compared to an actual telescope.

A monocular is more powerful than a pair of binoculars with the same functioning. However, it makes viewing distant objects about 50 percent easier. You can easily view objects at far greater distances easily using a monocular compared to a pair of binoculars.

What Makes a Great Monocular?

If you are wondering what features come together to form a perfect monocular, then wonder no more. Below, we have compiled a list that allows you to point out the aspects of an excellent monocular:


The more compact the design, the easier it is to carry it around. Compact design is also lightweight and extremely portable.


Choose a product that offers magnification to suit your needs. Higher magnification means you can see objects far away even more easily. However, higher optical power means a higher price, as well.

Prism Types

Three types of prisms are available for varying the optical range of a monocular. Roof prisms are good for long distances, Porro prisms are excellent for shorter distances, and Galilean prisms are best-suited for shorter ranges.

Prism Grades

These are the BaK-4 and BK-7 prisms with BaK-4 being superior and providing excellent light transmission.

Lens Sizing

The larger the lens, the larger its diameter will be. A larger lens will ensure a higher quality zoom in of the distant objects. A larger size, however, will make the monocular heavier.


Lens coatings comes in various levels. These include the simple coating and multi-coating for increased image quality and full coating for the best possible results. However, the price goes up with each layer of coating that is added to the monocular. It all depends on what you want to use your monocular for.

Review of the Best Monocular

Now, that you understand what features you need to look at when purchasing a monocular, let us look at some of the best ones up for sale in the market.

  • Easy to Carry it With Yourself Wherever You Go
  • Extremely Portable as it’s Lightweight and Has a Compact Design
  • Affordable, as it Offers Exactly What it Promises for a Fair Amount
  • A Magnification of 12x Helps in Viewing an Extremely Clear, Sharp, and Precise Image


  • The Included Tripod is Not Sturdy Enough to Hold Up the Monocular
  • The Field of View is Too Narrow and Does Not Allow You to Capture a Large View

Wingspan Optics’ Monocular has been created to allow you to see objects a whopping, 12 times closer and with increased clarity. The 50 mm lens incorporated into the design makes Wingspan’s monocular one of the best of all those up for sale. The robust, sturdy, and durable external armor helps you to have a firm grip and protects the equipment from damage.

Apart from giving you a clearer view, Wingspan’s monocular is both waterproof and fog-proof. This feature prevents moisture, dust particles, and other impurities from entering the monocular. As a result, internal fogging and lens clouding, both are kept at bay.

What good is a monocular that cannot be guided with just one hand? Definitely, no good and Wingspan’s monocular proves exactly that. Its perfect design allows smooth control with simply one hand. This monocular is perfect for bird watching, sightseeing, and even for watching wildlife.

Bottom Line

All in all, this is a great piece of equipment for a fair price. The monocular offers what it promises except it does not come with a lanyard and a sturdy tripod stand.

This high definition monocular has been specially designed to ensure easy gripping whilst you view everything up-close in high definition. No shaky viewing and no hand aches, this monocular is perfect for sightseeing and even bird-watching.

The lens is made from high-quality optical glass, which has a premium full, multi-coating. The Bak-4 prism is a fully glass-made prism that ensures extraordinary light transmission to allow the user to view everything with endless precision and brightness.

Unlike most others, Roxant’s monocular offers a wide view that is 6x30. This allows you to see more of what you are interested in, all in one go.

The monocular comes with its own retractable eyecup, so anyone can use it regardless of whether they make use of spectacles, or not. It also has its own carry pouch, belt loop, cleaning cloth, and neck strap.

Bottom Line

Although lightweight and portable with a sturdy build, this monocular fails to focus and provide the magnification that most people expect out of it. Due to this, it seems to be pricier than most other, similar models.

Bottom Line

Whilst some people are all applause for its clarity, some others seem to dislike it because of its cloudy view and narrow field of vision. This monocular is also not the best tool to use in bright light as it gives off a lot of glare.

As if all of this was not enough, Occer added even more features to this monocular. The device is not only water-resistant, but it is also compact and can be used easily with one hand.

Types of Monoculars

Now that you have compared and assessed various models available in the market, what you need to know more about is the types or kinds of monoculars that exist. There are two main types of prism monoculars which include the Porro prism and roof prism monoculars. Let’s get started:

  • Roof Prism Monocular

Roof prism monoculars are more compact and easier to hold but are more expensive.

  • Porro Prism Monoculars

These are affordable and have a good quality but are not as compact as roof prism monoculars. They cause strain on the hands if you hold them for longer periods. A variation known as the inverted Porro prism is, however, as compact as the roof prism monoculars.


Conclusively, a monocular is a great piece of equipment you would want to invest in if your hobby includes bird watching, sight-seeing, star-gazing, wildlife observation, hunting, and even just spying. There are various models available with various magnifications and power. So, pick one that suits your needs best.

People Also Ask

The following are questions that people usually ask when first getting to know about monoculars:

Are Monoculars Spotting Scopes?

Monoculars are mini versions of a spotting scope. A larger monocular with a bigger lens and wider field of view is referred to as a spotting scope. It is obviously larger and heavier.

What Powers a Monocular?

A monocular is similar to a binocular but only has one lens. It is used to magnify distant objects so you can see far away easily. It does not need any external power as it runs on optics and light transmission. However, one suited for night vision or one that is digital will require batteries to function.

What Do Lens Coatings Do?

A monocular is a modified refracting telescope that uses optics and light transmission to function and magnify images. The lens coatings offered on lenses help refract light perfectly. The better the coating, the lesser the loss of light during refraction and the stronger the light transmission channel. Hence, a powerful coating results in a powerful, bright, and sharp view.

What Do the Numbers on a Monocular Mean?

The two numbers mentioned with any monocular indicate the magnification and lens diameter. For example, if it says 10x42 in front of the monocular’s name, it means that the lens can magnify objects by about ten times and that the diameter of the lens is 42 mm.
