Binoculars are optical devices that are like two telescopes attached to each other, side by side. This allows them to be used at the same time by a single person. The person using the binoculars uses one eye to look at each viewer, making them easier and more comfortable to use.
With telescopes or other single-view optical devices, it can be difficult to keep your other eye closed for as long as you need to. However, with binoculars, you can keep both eyes open and focused on what you want to see.
Binoculars often need to be set to see a certain distance in order for both eyes to focus effectively on the same thing. This is usually done through small adjustment controls located right on the binoculars. Binoculars can be small, giving a small amount of magnification to help you see not-so-distant objects, or they can be very powerful, allowing you to see extremely long distances.
Generally, the larger the binoculars, the more power they have, although this is not always true. Some higher-end binoculars are smaller, but give you much more magnification for their size than even the largest ones.
You can buy binoculars at almost any sporting goods store, and you can also order them online. Many mail order catalogs also sell binoculars along with other sports equipment. People use binoculars for all kinds of things.
They are used for hunting, hiking, nature watching, bird watching, and even watching the night sky. In fact, if you look at the stars through powerful binoculars, you will see more stars than you can see with the naked eye.
Binoculars can cost as little as $25, or as high as hundreds or even thousands of dollars, depending on the quality you need.
