A peep sight is a small round or oval disc with a hole in the middle. It is placed between the strands of the bowstring at eye level. A peep sight acts a rear sight, precisely aligning the bowstring and target. Slighting is more precise when two locations between the archer's eye and the bull's-eye aligned than when just one is aligned. It can improve aiming accuracy.
