Binoculars are used for a lot of things. First thing to consider when looking at Binoculars is how we are going to use them.
The best binoculars for astronomy use are 7 x 50 or larger. The first is the number of times magnification, and the second is the diameter of the objective lens. Pocket binoculars are aptly named; they can be carried in a shirt pocket and are perfect for theatergoers, travelers, and wildlife enthusiasts.
Such lens cloths take even fingerprints and stains of all sorts off your binocular lens. Binoculars with larger fields of view may work better, but the cost is considerably more. A pair of binoculars that reads 7x50 can magnify things seven times stronger than they actually are with a 50mm objective lens.
Furthermore, binoculars with a wide field of view allow a user to observe a wide area, making it easier to observe star clusters, comets, and galactic clouds. As you can see from this article, the best binoculars repair strategy is preventive.
