How Far Can I See With These Binoculars?
How far can I see with my binoculars? This is a very common question and If we’re being honest, this is actually a question that doesn’t really make sense when we are talking about binocular magnification. To explain: A binocular’s main goal is to magnify whatever you’re looking at, such as the moon, which is approximately 240,000 miles away. If you want to see even further than that, you can look at the sun which is 93 million miles away (not recommended unless you want to burn out the retina in your eyes!). So, it’s not really a question of how far can binoculars see, but how much you want to magnify the object you’re seeking to bring closer.
What Does Magnification Mean?
Magnification is how much larger an object appears when viewed through a binocular compared to how large the same object would appear when viewed with the naked eye from the same distance.
For example, if you are trying to decide between an 8x or 10x, an animal or person will appear ten times larger through the 10x binocular than with your normal eyesight. Or eight times larger with the 8x and so on.
Let’s simplify it even more. You’re standing at the edge of a 100-yard clearing. You’re looking at a tree line at the opposite end of the clearing. With a 10x power binocular, the trees will appear as if you’re only 10 yards versus what the tree line would look like with your unaided eye. Basically teleporting you 90 yards closer for a more detailed look.
What kind of vision does binoculars give you?
Binoculars do not simply give you a magnified view of objects – they also deliver a brighter and more detailed image. The large objective lenses collect more light than the naked eye, letting you see a larger collection of stars and nebulae in the night sky, and finer details in wild birds and flowers.
Another great visual attribute of binoculars is the stereoscopic field of view. By using both eyes, you can watch objects while maintaining the sense of depth. As a result, you can enjoy viewing a distant subject such as an actor on stage as if they were close by, with a realistic three-dimensional feel.
