You'll need to choose the magnification power of your binoculars. There is also the Golden Ring binoculars for added brightness and clarity.
You may use your binoculars for sporting (watching your favorite team from the stands), hunting (they won't weigh you down or take much space), birdwatching (you can hold them steady for long periods without tiring), or just everyday nature lovers. If you are a backpacker or will be doing your birding on a bicycle, then you may wish to consider mid size or even compact binoculars. But the optical surfaces still need protection from scratches and other damage.
As with the aperture of a camera lens, the size of objective lens determines the amount of light that can enter your binoculars. Binoculars for deer hunting might not be the best type that you would use for hunting rabbits. Choosing a telescope is not an easy choice to make and is one that really needs research.
The average binoculars user should go for a pair having magnification between 7 and 9x. So, get out there.
