Distance magnification aids such as monoculars and binoculars are used for viewing print and objects in the distance such as TV, pedestrian signals, train indicator boards, whiteboards, screen presentations, cinemas, concerts and sporting events.
The magnification level of monoculars and binoculars are specified by two numbers (E.g. 8 x 20). The first number indicates that the telescope has 8x magnification and the second number indicates a 20mm diameter front lens.
As the magnification of the distance viewing aid increases the area seen through the device (the field of view) decreases. Because of the reduced field of view, pinpointing the object you are looking for will take practice.
