A lens meter having a projection system (5) provided with a projection light source (7) adapted to project a measuring beam onto a lens (l4) to be examined, and a light receiving system (6) provided with a light receiving element (l5) adapted to receive the measuring beam which has passed through the object lens (l4), the optical characteristics of the object lens (l4) being determined on the basis of a position in which the light receiving element (l5) receives the measuring beam which has passed through the object lens, comprising an object lens turning mechanism (l6) adapted to turn the object lens (l4) around a center (O) of a turning movement corresponding to that of a turning movement of an eyeball in a spectacle lens-worn state.
