A great part of using them properly is knowing how to focus binoculars. It’s safe to say that it’s one of the biggest myths when it comes to binoculars. Even though it sounds like a piece of cake, a lot of users don’t know how to focus their models. And that’s nothing to be embarrassed about. There are numerous brands that produce different types of binos. Plus, there are several types of focusing systems, too. All of that may additionally confuse the user.
As we all understand, focusing means a lot when you go outside. Whether it’s hunting or birdwatching or something else entirely, you should know how to focus and calibrate your model. It’s how you can get the most out of the whole outdoor experience.
That’s why today’s post will deal with why you should focus, the types of focusing, steps, and useful tips.
Why You Need to Focus Your Binoculars
People who have no or very little experience in binoculars may ask themselves this. What’s the purpose of focusing anyway?
When you step out of the door and start using the binos, you must know how to focus. It’s a way of fixing the faults in the visuals or your own eyesight. With the focus, you get clear visuals that accent the details in the observed object. In short, you can see a lot when you zoom in when you use a properly focused and calibrated binocular model.
Also, focusing helps you eliminate the burring which may appear in visuals. There are no spots or weird shadows while observing. If you experience a double vision, focusing will take care to get rid of that.

Mastering the Focus and Calibration
First, we’re going to talk about the center focus system that most binos have out there. If a model has this system, there is a focus wheel paced at the center.
You do simple focusing when you look with both eyes. At the same time, you make small modifications by turning the center wheel. When the image in front of you is detailed and clear, you can stop.
You’ll notice that both of the barrels move and adjust when you focus. It’s useful to know that this kind of modification doesn’t calibrate the model. We’ll cover that bit in a second.
How to Calibrate
Instead of the center focus wheel, calibration includes a diopter ring. In most cases, it’s placed on the right barrel. In some models, it can be on the left ocular. Calibrating means that you focus one barrel at a time while at the same time you’re playing with the diopter ring. With it, you can adjust the differences between the visual ranges of both eyes. This comes especially handy for individuals who have eye situations like nearsightedness.
The calibration process occurs once. That’s when you use the binoculars for the first time. Note that you may have to do it again if you borrow them to someone else or if someone plays with the binos.
To be more precise, you begin by picking an object. Preferably, it should be around thirty feet distanced from you. That’s around ten meters. Then, look through the eyepieces. Most frequently, you shut your right eye first. Twist the focus wheel until the object you’ve chosen is perfectly in focus when you look with your left eye. Open your eyes. After that, close the left eye and adjust the wheel until you have achieved the focus you want. You know you’ve succeeded when you open you open both eyes now and see the object clearly. It’s useful to know that some models are capable of locking the preferred settings. To confirm that, you can consult with the manual.
Additional Tips for How to Focus Binoculars
Glasses wearers should be extra careful when buying and focusing binos. The eyepieces, as well as the rings, should be able to fold up and down. If they can do that, you can operate with binos without taking your glasses off. So, it’s advised to try on binoculars in the store. Also, check the eye relief distance in the specifications section.
Moreover, some users experience fatigue and have to strain their eyes to focus. If that happens to you, too, know that there may be something wrong with the model. It’s possible that something is wrong with the alignment. Don’t hesitate to reach out to the seller or the manufacturer to deal with it.
Additionally, if you don’t want to close each of your eyes, close the objective lens with your hand. While you’re doing that, make sure your hand isn’t touching the glass.
What about Binoculars with a Fixed Focus System?
Another name for this focus system is the individual focus. The abbreviation IF is common. It differs from the central focus system by not having the center focus wheel. Instead, every eyepiece has a diopter scale.
What’s interesting is that the adjustment is the same for both of these systems. Just if you want to focus with your right eye, you don’t twist the center focus wheel. But, you use the diopter on the appropriate side. The same for the left side, too.
With the individual focus system, you don’t have to re-focus a lot. That’s one of the perks of the system. If you are, by any chance, re-focusing, then something may be wrong with the model. So, it’d be best to call the manufacturer.
All things considered, focusing isn’t a very tough task like so many people think. In fact, once you know how to do it, it’s fun and exciting. Whether you’re planning to go birdwatching, go on a safari, travel or even attend a sports event or a concert, you should know how to focus your binos. Only that way you’ll get the most out of the model. And now that you understand how focusing is done properly, you may say goodbye to poor visuals.
