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, each designed for specific shooting scenarios. These sights can improve target acquisition speed and precision, especially at longer distances. Many optical sights also feature adjustable reticles, which help shooters compensate for factors like wind and bullet drop. Overall, they are essential tools for both recreational and competitive shooters.
