The bending of seismic rays at curved interfaces which act like optical lenses, resulting in focusing or defocusing wavefronts and distorting structure and velocities calculated from normal-moveout measurements. The distortion becomes greater as the curvature of the velocity lens increases and as the depth of the feature being studied increases.
