Binoculars
Binoculars are an optical device used for viewing distant objects with both eyes. They consist of two telescopes mounted side by side, allowing for a wider field of view and greater depth perception. Binoculars are commonly used for activities such as birdwatching, hunting, wildlife observation, and stargazing. They come in a variety of sizes and magnifications, with the most common being 8x42 and 10x50. The first number represents the magnification power, while the second number indicates the diameter of the objective lens in millimeters. Higher magnification allows for closer views, but can also result in a narrower field of view and more noticeable hand shake. Binoculars are a versatile and portable tool for exploring and observing the world around us.
