Optical sights are devices used to enhance aiming accuracy for firearms, archery, and other precision sports. They work by using lenses to magnify the target and provide a clearer view, allowing users to align their shots more effectively. Common types include rifle scopes, red dot sights, and holographic sights. These sights can be mounted on various weapons and are designed for different shooting scenarios. They often feature reticles, which are crosshairs or other aiming points, to help shooters focus on their target. Optical sights are popular among hunters, competitive shooters, and military personnel for their ability to improve targeting precision.
