Most of us own a pair of binoculars. We use binoculars to watch a match, or while hunting or even while trekking etc. It is used to view the objects, people or routes or structures that are far away, and out of sight for normal eye view. Binoculars use telescopes or refracting lenses, and serves as a magnifying glass. These refracting lenses are placed side by side, so that you can hold it right in front of your eyes.
