Binoculars are used for a lot of things. Since the dawn of time, man has looked up at the heavens and wondered the beauty it may contain.
Binoculars have two specifications marked on the body of the binocular in the form of 7x 50, where the first number represents the magnification, in this case 7 times, and the second the aperture ,50mm in this case. There are many different features to look for when making your purchase. When choosing a night binocular first decide what you are going to use it for.
A simple coating was devised to prevent this, by allowing more light to pass through the lens, and less to be reflected back. Most binocular lens protectors are replaceable. In order to define the quality performance of their products, binocular makers present the field of view in mathematical conversions that show a variance of fields.
The larger the second number after the "x", the more light that enters the binocular and the image will become brighter. Enjoy you view!
