Monoculars are handhelds, small telescopes that are used for observing distant objects. The monocular has one lens and one eyepiece. The user looks through the eyepiece, which magnifies the image of the object being viewed. Monoculars are used for observing birds, animals, nature, hunting, or shooting.

You can attach your smartphone to most models and take photos or even videos. Monoculars become more and more popular for outdoor activities. Unlike binoculars, monoculars are generally lighter and easier to use. To be always at hand – that’s its purpose! Just imagine: when you hear birds singing in the long distance, you can see the singer and even witness a live bird dialogue.

What Are Monoculars Required For?

Monoculars are used for a variety of purposes, including bird watching, hunting, hiking, and stargazing. They are also useful for viewing objects that are too far away to be seen clearly with the naked eye, such as the Moon and planets in the night sky or a dash target. Monoculars are usually compact and lightweight, making them easy to carry with you on your travels. They are an essential piece of equipment for anyone who loves spending time outdoors and exploring the world around them.

Pros and Cons of Monoculars

Monoculars are a great tool for birders and other nature enthusiasts. They are small, lightweight, and easy to carry. But there are some drawbacks to using monoculars. One downside is that they can be difficult to use for extended periods of time. This is because you are using only one eye to look through the lens. This can cause eye fatigue and headaches. Another downside is that monoculars can be hard to keep steady.

This is because you are only using one hand to hold them. If you are looking at something far away, you may need to brace your hand against something to keep the monoculars steady. Overall, monoculars have some pros and cons, and considering them, you can choose the best bird-watching monoculars. But they are still an excellent tool for birders and nature enthusiasts.

Monoculars Buying Guide

The choice in favor of one or another model of the device will help to know its basic characteristics. What parameters are worth paying attention to when choosing a monocular? In this guide, we’ll show you what to look for when selecting a monocular and give you some product recommendations and help you choose the best monoculars for bird watching.

Magnification ratio

When choosing a monocular, the first thing to consider is magnification. You’ll want to make sure the monocular you select has the appropriate level of magnification for the task at hand. For example, if you’re using it for bird watching, you’ll need a higher magnification than if you were using it for general observing. This parameter indicates the degree of approximation of the object. For example, a telescope with a magnification of 10 times will make the object seem 10 times closer than it really is.

Field of view

This is the linear size of the area of space seen through the eyepiece. Here you should remember a simple rule: the higher the magnification of the instrument, the smaller its field of view.

Lens diameter

The next thing to consider is the size of the objective lens. Lens diameter (aperture) refers to the size of the front lens of the instrument in millimeters. The bigger the aperture, the less demanding the instrument to ambient light. For daytime use, a lens with a diameter of 25-30 mm is enough, and for observing at dusk, 40-50 mm. However, large objective lenses can make the monoculars heavier and more difficult to hold steady.

Type of prism

Another important consideration is the type of prism used in the monocular. There are two types of prisms—roof and Porro. Roof prisms are typically found in compact monoculars while Porro prisms are found in full-size monoculars. Roof prisms offer the advantage of being more compact, but they can be more expensive. Porro prisms offer a wider field of view and are typically less expensive.

Optics material

Material optics of monoculars varies depending on the manufacturer and price category. In brief, there are two types of materials: plastic and glass. Devices with plastic lenses are cheaper, but glass provides a clearer picture.

Other parameters

An important role when choosing a monocular is also played by: the material of the body of the optical device, the water resistance of the model, and the possibility of mounting it on a tripod.

Coatings on the lenses

Finally, you’ll want to consider the coatings on the lenses. These coatings help to reduce glare and improve image quality. The most common coatings are anti-reflective (AR) coatings.


It is more convenient to use the monocle using a tripod. The monocular focus is better on a tripod and produces a sharper image. As a rule, many monoculars come with a tripod, but it is of poor quality and does not give the same effect as a solid, stable tripod. I recommend buying a tripod separately in order to enjoy a stable picture.

If you are looking for a bird-watching monocular, you should use a monocular with high magnification (10x or higher). Such a monocular will allow you to enjoy the view of even the smallest bird species. But a powerful zoom requires great stability of the monocular. With these factors in mind, you will be able to choose the best monocular bird watching.

Monoculars for Bird Watching FAQ

Frequently asked questions about the types of monoculars for bird and their characteristics and use.

What’s better than binoculars or monoculars?

A monocular is a better choice for birding on a long distance trip because it takes up less space. However, binoculars are a good choice if weight is less of a concern or you need a fuller visual picture. It doesn’t matter what you choose binoculars or monoculars for bird watching. The main thing is to be comfortable to use.

Can I use the monocular for bird watching if I wear glasses?

Yes, you can use the monoculars for bird watching if you wear glasses. The eyecup of the monocular can be adjusted to accommodate your glasses, so you will still be able to see through the lens clearly. Additionally, many monoculars come with a neck strap, so you can keep your hands free while you’re bird watching.

What keeps monocles from fogging up?

Monocles don’t fog up because they are filled with an inert gas that prevents condensation from forming on the inner optical surfaces.

How can I clean my monoculars for bird watching?

To clean your monocular for bird watching, you will need a lens cleaning cloth and some lens cleaning solution. First, put a few drops of lens cleaning solution onto the lens cleaning cloth. Then, gently wipe the lens of your monocular with the cloth until it is clean.

What does tenfold magnification mean?

The magnification ratio is the binoculars’ ability to bring the object of observation closer by a certain number of times. For example, a binocular with 10x magnification will show you an object 100 meters in front of you as if it were 10 meters away.

What is the luminosity of a monocular?

The larger the lens, the greater the luminosity of the monocular. But you should understand that a large entrance lens is not always better, because enlarging the aperture makes the monocular heavier. Let us give you some examples: a 10×40 monocular has dimensions about half that of an average binocular, but a 5×15 monocular can be as big as your thumb.


A monocular for bird watching is an optical device used to observe distant objects. A monocular can be compared to a miniature low-power telescope or telescope. This device is held in your hand like binoculars, but you look through it with one eye, like a telescope. The technical characteristics of a monocular are similar to those of binoculars and telescopes, but its dimensions are much smaller.

A monocular is typically smaller and lighter than binoculars, making it easier to carry and hold steady. Many monoculars now come with digital features such as zoom and image stabilization. Monoculars are ideal for bird watching, hiking, nature observation, and other activities where you need to keep both hands free. They are also handy for stargazing, concerts, and other events where binoculars would be too bulky or intrusive. I hope this article has helped you choose the best monocular bird watching.
