Binoculars
Binoculars are optical instruments that are perfect for a variety of leisure and work. Binoculars not only enlarge the image of objects, but also provide a brighter and more detailed image. Large objective lenses collect more light than can be seen with the naked eye, allowing you to see a huge number of stars and nebulae in the night sky, mountains and hollows on the horizon, flower details and bird colors.
Another great visual attribute of binoculars is the stereoscopic field of view. By using both eyes, you can observe objects while maintaining a sense of depth. As a result, you can enjoy viewing a distant object, such as an actor on stage or an athlete on the field, as if they were nearby, with an immersive effect.
The body of the binoculars has a series of numbers, such as "6.5 x 21 7.5°". These important numbers allow you to find out the main characteristics of the binoculars. The first tells you the magnification factor, which tells you how many times the binoculars can magnify an object. The following shows the size of the objective lenses in millimeters, which informs you about their ability to gather light. The last one is the angle of view (called the real field of view) that you can see through the binoculars. Understanding these numbers will help you a lot when choosing binoculars.
