Field of view means the area that is being covered when you are using binoculars.
Field of view is another issue when choosing the right binoculars.
It is the degree by which an object will appear larger.
Therefore higher magnification will result in a narrower field of view.

This raises the question of what does 10 50 mean in binoculars especially in relation to the field of view.
If you own larger lenses that simply means you get to see more area as compared to binocs with smaller lenses.

For magnification 20x field of view is around 3 3 degrees 199yds 1000 ft.
Binoculars or field glasses are two telescopes mounted side by side and aligned to point in the same direction allowing the viewer to use both eyes binocular vision when viewing distant objects most are sized to be held using both hands although sizes vary widely from opera glasses to large pedestal mounted military models.
The first number followed by an x is the magnification.
If you need a powerful binocular with a reasonably wide field of view magnification 15x is the ideal choice which has around a field of view around 4 2 degrees.
Assuming you re less concerned about size and weight you can look at midsize and full size models 8x32 and 8x42 binoculars are popular with birders while 10 power magnification might seem helpful in looking at a small animal an otherwise identical pair of binoculars with a magnification of 8 will have a wider field of view which is key to locating birds.
Porro prism binoculars provide greater depth perception and generally offer a wider field of view.
It is determined by multiple components in the optic that includes the eyepiece thickness of the lenses position in its assembly and magnification.
The larger the value is the wider the viewfield available.
In porro prism binoculars the objective or front lens is offset from the eyepiece.
For example binoculars with a wider field of view are advantageous for locating fast moving wild birds within the viewfield.
