Points to Consider before you Buy Binoculars in India
Binoculars, in its simplest definition, are magnification tools consisting of two telescopes mounted on a metal or plastic frame so that a spectator can view the images as if they were much closer.
In a nutshell, binoculars use a series of lenses, elements and prisms to produce an enlarged vision of distant people, places or things. The use of two parallel optical tubes allows you to observe with both eyes open, which is more comfortable and natural than using a telescope or telescope that requires you to keep an eye closed.
Whether you are a serious wildlife observer or just want a better view of the antics of the garden's blue tits, decent binoculars will bring you terrible pleasure. Make sure you have a good idea of how you will use them before buying.
What to look for when buying binoculars
At its most basic level, the main purpose of any binoculars is to enlarge the view and then bring distant objects more clearly into the view making them appear closer or larger. Therefore, it is obvious that the most important thing to know and get is to what extent a particular pair magnifies the view and in fact how much magnification is needed for what you intend to use them for.
The number that comes immediately after magnification when looking at the name on binoculars indicates the size (diameter) in millimeters of the main objective lenses (those are the largest at the end of the binoculars). So, using the examples above, an 8x42 binoculars have 42mm diameter lenses. A 10x42 will also have the same lenses (42mm), but with a higher magnification.
The basic design of binoculars falls into two broad categories which are largely the result of what type of prism they use inside them to correct the image and flip the right side after it has passed through the lens.
Also consider external features such as waterproofing, frame material, eyepieces, dioptric adjustment, optics, lens coatings, prisms and prism coatings.
