FIELD GLASSES Meaning and
Definition
-
Field glasses, also known as binoculars, are handheld optical devices consisting of two aligned telescopes held together side by side, allowing for the observation of distant objects with enhanced detail and clarity. These devices are commonly used in a wide range of activities, including birdwatching, hunting, stargazing, and military operations.
Field glasses typically consist of a series of lenses and prisms that modify the incoming light to produce an enlarged and focused image. The lenses at the front of the device, known as the objective lenses, gather the light from the scene being observed. This light is then directed towards the eyepieces through a series of prisms and lenses, which invert and magnify the incoming image. The eyepieces, positioned at the back of the field glasses, allow the viewer to see the magnified image with both eyes simultaneously, providing a more immersive and comfortable viewing experience.
Field glasses come in various sizes, with different magnification levels and lens diameters. The specific specifications are often denoted by a combination of numbers, such as "8x42" or "10x50." The first number indicates the magnification power, meaning the object being observed will appear that many times larger than with the naked eye. The second number refers to the diameter of the objective lenses in millimeters, which affects the amount of light the device can gather.
Overall, field glasses offer users the ability to explore and study distant objects, making them invaluable tools in various outdoor pursuits and professional endeavors.

Etymology of FIELD GLASSES
The word "field glasses" is derived from the combination of two words: "field" and "glasses".
The term "field" originates from the Old English word "feld", which referred to an open expanse of land, typically used for cultivation or pasture. Over time, the meaning of "field" expanded to include various types of outdoor spaces.
The word "glasses" relates to the optical instrument used for vision correction or magnification. It comes from the Old English word "glæs", which originally referred to a transparent substance made from molten sand (silica). With advancements in technology, "glasses" eventually became synonymous with eyeglasses and other optical devices.
When these two words are combined, "field glasses" thus refers to optical instruments used for observing distant objects or scenes in open settings such as fields.
