Have you ever looked at a pair of binoculars and noticed two numbers separated by an "x"? And have you ever wondered what those numbers meant? For example, 8x42.

If so, today is your lucky day! Keep reading to learn everything you want about those pesky numbers on binoculars.

Let's start with the first number, shall we? This number is called magnification. Magnification is how many times closer the object will appear through the binoculars than it would to the naked eye. So, if you're looking at something 800 yards away and using 8x42 binoculars, that object will appear as if it's only 100 yards away.

The second number is called the objective lens. The objective lens is simply the diameter of the front lenses of the binoculars in millimeters. In our example above, those lenses would measure 42mm in diameter.

Now that we know what each number means let's talk about how they work together. The magnification power will always be listed first, followed by the objective lens. So, if you see a pair of binoculars that say 10x50, they have a 10x magnification power and 50mm objective lenses.

But wait, there's more! In addition to understanding what each number means on its own, it's also essential to know how they interact with one another. For instance, all else being equal, a higher magnification power will result in a smaller field of view. Conversely, a lower magnification power will give you a wider field of view. Additionally, a larger objective lens will result in brighter images and make the binoculars heavier and more difficult to hold steady.

Conclusion

Now that you know what those numbers mean enjoy all the world has to offer through your newfound knowledge! No longer will you look at a pair of binoculars and wonder what those pesky numbers mean. Now, you'll be able to tell exactly what each number signifies at a glance.

And who knows? Next time someone asks you about those numbers, you can also impart your newfound wisdom to them.
