Sometimes targets will often "seem" to drift, blur or wobble against their background making focusing a good shot on them very difficult. This effect is known as parallax.
Scopes such as this have Parallax adjustment which basically means you are able to adjust the scope using the twist dial in this case on the lens to factor it out of the equation and get a vastly improved range of focus.
The effect varies in intensity and effect at different ranges so the scope features a range of adjustment settings.
Parallax yard settings from 15 yards adjusted by the objective i.e., it is an AO "Adjustable Objective" scope.
