An optical sight is a device used to enhance the aiming accuracy of firearms, cameras, or other optical instruments. It typically consists of lenses that magnify the target and a reticle, which helps the user align their aim. Optical sights are commonly found on rifles, handguns, and even binoculars, making them essential tools for hunters, sport shooters, and military personnel. These sights come in various types, including red dot sights, scopes, and holographic sights. Each type offers different features, such as magnification levels and reticle styles, catering to specific shooting needs. By providing a clearer view of the target, optical sights improve precision and overall shooting performance.
