lens surfacing process by grinding the back surface at an angle relative to the front surface. When the lens has nonzero power, grinding the back surface at angle to the front surface shifts the optical center of the lens. Consequently, for lenses of sufficient power, it is possible to produce a prismatic effect by simply movingor decenteringthe optical center of the lens Figure 2
