Field glasses, commonly known as binoculars, are optical devices designed for viewing distant objects. They consist of two telescopes mounted side by side, allowing users to see with both eyes. This design provides a three-dimensional view, making them ideal for activities like birdwatching, hiking, and sporting events. Field glasses come in various sizes and magnifications, catering to different needs. They typically feature adjustable eyepieces and a central focusing mechanism. Many models are also waterproof and fog-proof, enhancing their usability in various weather conditions. Popular brands include Nikon, Leica, and Bushnell.
