Binoculars can be great fun for anyone. There is a lot of versatility when it comes to them, and the entire family can end up using the same pair of binoculars for different reasons. You can use binoculars for birdwatching, for helping you cheat while trying to play a game of high stakes hide and seek, when you are gone out hunting, or to even look at the stars if you want. Now, you might be curious about a lot of things when it comes to binoculars, and one of those questions might be how far can you see with 10x50 binoculars and so on, and before we get to answering that question, it is important that we understand the basics of binoculars beforehand.
What Are Binoculars
A lot of people tend to confuse binoculars and telescopes, and while they might serve the same purpose, there is a difference between the two. Binoculars essentially involve a pair of telescopes that are aligned at natural eye level, allowing us to be able to at distant objects from a magnified view using both of our eyes instead of just one.

The Anatomy of a Binocular
- Objective lenses – These are the lens that is placed furthest away, and almost opposite to the user’s actual eye. Their purpose is to capture light and to direct that light towards the eyepiece in order for the person to be able to see.
- Eyepiece Lenses – These are the lens which we place closest to our eyes. They are the smaller lens in this scenario. The eyepiece helps to focus the light and the image, allowing us to be able to see it. We can also change the focus on the eyepiece lens, allowing us to blur or increase the sharpness of whatever we might be looking at.
- Focus Wheel – This is located near the eyepiece and it allows us to align and focus on the picture to whatever extent we want.
- Prisms – These are located between the objective lens and the eyepiece lens. Their purpose is to fix the image orientation since the image is originally created in an inverted form. So, the prism reorients the image.
- Chassis – This can be described as the body of the binoculars.
What Magnification Means
Before we answer our burning question, it is important that we understand what exactly we mean when we are talking about magnification. Magnification is how much larger an object can be seen via a binocular lens as compared to seeing the same object from the normal naked eye.
If you want to learn the magnification of your binocular lens, then you only have to look at the first number of your lens. So, if your binoculars have a 6X30 magnification, the 6X is the amount of magnification that your lens provides. This means that the image will be magnified as 6 times bigger than its actual size, hence the 6X figure. The second figure represents the measurement of your objective lens. This figure is usually estimated in millimeters. So, 6X30 binocular means that you can observe any object up to 6 times bigger than its actual size, and through a 30mm lens.
If you happen to have a 10X50 binocular lens, then it means that you can see an object magnified up to 10 times bigger than its actual size via a 50mm objective lens. This is a pretty decent amount of magnification, and there is quite a lot that you can do with a 10X50 binocular lens, and this includes:
- Bird spotting, especially birds that hide in thicker foliage and trees will be a lot easier because the 50mm lens will allow for more light to enter your field of vision.
- If you are someone that enjoys stargazing or being out at night, then you can see the moon really clearly on a clear night. In fact, you can even see craters along the surface of the moon with these binoculars.
- Interestingly, you can even see other planets through these binoculars during days when the planets are clearer and appear to be closer to the earth. While you will not get clear views, you can still view all of the eight planets through these binoculars.
- If you go to clearer skies with less light pollution, you can even spot other galaxies and clusters through these binoculars.
While you might be tempted to get the highest magnification binoculars, it is important to understand that these kinds of binoculars require a lot more stability. They get easily disturbed and it will take a while for images to stabilize, so fast movements and smooth transitions are impossible when it comes to using high magnification binoculars. Most of us do not really need high magnification binoculars, and we can easily have our needs met with under 10X binoculars.
