In the binoculars specs sheet, eye relief is a term used to describe the distance between your pupils and the back of the eyepiece lens.
To enjoy a brighter image, your eyes must be in some allowable range defined by the binocular manufacturer. If eye relief is too short, you cannot feel the sharpness and brightness of the image.
Also, it’s not just the length of eye relief that is important. Other technical parameters such as the magnification, field of view, prism design and quality, etc., are equally essential to look at for making a sound basis for the purchase.
For example, if you look through a pair of binoculars with very steep eye-relief angles, you will find it more challenging to focus your eyes on distant objects; also, it may cause distortion.
In some cases, you may find a pair of binoculars with short eye relief but with a large maximum magnification (for example, 10x or 15x), and it might be a waste of time and money if you are someone who needs a longer eye relief.
But you do not need to worry. This article is all about finding the best binoculars with an eye relief range to suit your requirements.

Frequently Asked Questions
1. What is long eye relief for binoculars?
Each binocular has some allowable distance between your eyes and the eye[piece lens. If you are within the defined range, you will enjoy the image quality fully. Else you will not be able to see the image around the edges. This is because your eyeglasses move your eyes further away from the eyepiece lens.
So, a long eye relief means that the binoculars allow a larger distance between the eyepiece lens and your eyes. This will ensure a quality image for both eyeglass wearers and non-wearers.
2. How much eye relief do you need?
There are no hard and fast rules to determine this. But, generally, the average eyeglass wearer needs an eye relief greater than 17mm.
3. What is the field of view?
FOV is just the horizontal distance or width that your binoculars can capture. For example, if your binoculars can capture 400ft of the horizontal area at 1000 yards of the target, then your FOV is 400ft. It decreases with higher magnification because the target’s image becomes bigger than before.
Long eye relief binoculars are suitable for sporting, birding, nature viewing, and celestial object viewing. They have a wide field of view, making it easier to look at birds or something far away.
