Parallax is defined as an object appearing as if it is positioned differently when it is looked at from different angles or different positions.
Parallax adjusts the target to the reticle (crosshair). The target image and the reticle must be on the same focal plane within the scope or there is room for apparent movement of the reticle on the target when the shooter'e eye moves (or is positioned differently at the scope).
