Any stain or mark on the surface of a binocular lens tends to scatter light, thereby producing low-contrast viewing. This article is intended to help cut through some of the confusion on getting a good pair of binoculars.
The power of the optics is expressed as two numbers, such as 7 x 35. Many people prefer to carry binoculars around freely, rather than in a case. By using your binoculars case for storage between observations, you will provide maximum protection for your binoculars.
They suck dirt off the lens surfaces leaving them crystal clear. Distance measuring is important, but binoculars with a wide field of view allow you to see a larger picture, and keep an eye on several objects at once. Apart from a large number of big companies, there are local manufacturers which produce night-vision binoculars at a much lower cost.
My personal experience has revealed binoculars in the two to five hundred dollar range perform well and I ve never missed a sighting because of their quality. If you want powerful night vision optics for a cheaper price, consider night vision monocular.
