Binoculars are a great way to get a closer look at things, but only if you know how to use them correctly. Many people don’t realize that there is a secret to getting the best possible view through binoculars. The secret is called eye relief, and it can make a big difference in what you see.
In this article, we will show what you need to know about binocular’s eye relief and how to use them to your advantage. Also, we will explore how to measure it, and how to choose the right amount of eye relief for you. Let’s start –
What is eye relief in binoculars?
When you are looking for binoculars, you may come across the term “eye relief.” But what is eye relief in binoculars? One of the most important, yet least understood, features of binoculars is eye relief.
Well, the distance between our eye and the binocular eyepiece lens is known as the eye relief distance. It is important because it determines how much of the field of view you will be able to see. If the eye relief is short, you will not be able to see the entire field of view. And if the eye relief is too long, you will have to hold the binoculars away from your face, which can be uncomfortable.
How much eye relief do you need?
The eye relief distance is mostly dependent on how you will be using them. For example, if you wear eyeglasses while using binoculars, you will need more eye relief than someone who does not wear glasses. Here’s a quick guide to help you determine how much eye relief you need.
In case you wear glasses or sunglasses, you should choose binoculars with at least 15mm of eye relief. This will ensure that your glasses don’t interfere with your view of the eyepieces. If you don’t wear glasses, you can get away with less eye relief, but we still recommend at least 10mm for a comfortable view.
However, more than 20mm is regarded as long eye relief whereas less than 13mm is considered short eye relief.

How to measure eye relief?
When shopping for binoculars, it is important to know how to measure eye relief. To determine eye relief, hold the binoculars up to your eyes and look through them at an object in the distance. Then, move the binoculars back and forth until you can see the object. Once you have found the sweet spot, measure the distance from your eyes to the lenses of the binoculars. This is your eye relief.
Note: Keep in mind that eye relief varies from person to person. What works for one person may not work for another.
Why is binocular’s eye relief important?
Before you buy a pair of binoculars, it is important to understand the concept of eye relief. Here are three reasons why eye relief is important when choosing binocular’s.
Eye relief is important because if the eye relief length is too small, you will not see the whole field of view. As some people need more than others. And that’s the main reason why binoculars have different eyepieces is to provide different levels of eye relief.
Again, if you wear glasses, we already mentioned that you will need even more eye relief. As a result, you will be able to see through both the lenses of your glasses and the eyepieces of the binoculars. If you don’t have enough eye relief, you will only be able to see part of the image, not the complete image of the distant objects.
Moreover, it allows you to see the entire image without having to move your head around. It also helps you focus on the image and makes it easier to hold the binoculars steady. Besides, binoculars with suitable eye relief are more comfortable to use. Because you don’t have to put your eyes right up against the lenses to see clearly
So far, it’s crucial to find a binocular that has enough eye relief for you because otherwise, you won’t be able to use it properly as well as comfortably.
Frequently Asked Questions(FAQs):
Can I adjust the eye relief power in binoculars?
Yes, you can typically adjust the eye relief power in binoculars. This is done by moving the eyepieces in or out of the barrels. Most binoculars have a diopter adjustment knob that lets you fine-tune the focus for each eye.
What is a good eye relief for binoculars?
When looking through binoculars, your eyes should be positioned in such a way that you are comfortable and can see through the entire lens. The ideal eye relief for binoculars is 10-16mm. This range allows for a wide field of view and a comfortable viewing experience.
What if I don’t wear glasses while using binoculars?
If you don’t wear glasses while using binoculars, you may experience some discomfort. This is because the eye relief, or the distance between your eyes and the lenses, is not ideal. Without glasses, your eyes are closer to the lenses and this can cause strain. Additionally, you may not be able to see the full field of view. Wearing glasses will provide you with a comfortable experience and you can see everything.
Eye relief is an important aspect if you want to be able to use them properly. With a little bit of knowledge, you can make sure that you get the most out of your binoculars and enjoy using them for many years to come. Whatever the activities are e.g birding, hiking, wildlife viewing, whale watching, and many more, right eye relief is a must.
By keeping the above tips in mind, you can be sure to find a pair of binoculars that will be comfortable for you to use.
