All binoculars have a pair of numbers ##x##, for example, 10x42.
The first number is the power (magnification) and the second number is the size of the lens (42mm). In this example, the 10 means 10 times closer than seeing the subject with only your own eyesight.
The lower the magnification, the brighter the subject will appear and the wider the area that you will be able to see. So, decide on what you are normally looking at: birds, landscape, etc.
The more powerful binocular will be harder to keep steady because of the small FOV (field of view). If you are going to use the binoculars at dusk a lot, you will need a larger lens size (maybe a 50mm instead of the 42mm lens. The larger the lens size, the more light that is let into your eyes.
The coated lens also affects the brightness of the subject that you are looking at. Coated lenses increase the amount of light that will make it all the way through the binoculars to your eyes. The more light, the more contrast.
The coating of the lens will increase the cost of the binoculars.
There are various coating options available ranging from coated - fully coated - multicoated - fully multicoated. Coated lenses are the lowest quality. Fully coated lenses are quite economical and can work well for you, depending on your needs. Multicoated or fully multicoated lenses are both very good choices. Fully multicoated lenses give the best light transmission and brightest images, and therefore the most desirable
Field of view is the width of the area you see through the binoculars usually shown as metres at 1,000 metres e.g. 119 metres FOV at the 1,000m view.
If you want to watch a yacht race and take in as much the action as possible you would look at a wide FOV. If you wanted closely examine small objects from a distance you would look at a narrower FOV. The narrower the FOV, the larger the magnification.
The field of view is normally in the binocular specifications and is often printed on the binoculars as well.
