The numbers describe the configuration of a binocular. Let’s take 8×42 binoculars as an example. The first number (8) refers to the magnification, or, how many times closer an object will appear when looking through the binocular compared to looking through eyes only. The second number (42) indicates the diameter of the objective lens (the light-gathering lens) of the binocular and is measured in millimeters.
