Lens decentration is the displacement of the optical center of a spectacle lens relative to the pupillary center.

Lens decentration means the optical center of a spectacle lens is displaced from the center of the pupil. Looking through a powered lens away from its optical center can create a prismatic effect, shifting the apparent position of what you see.
