Claim 0:
1. A method, comprising:
forming, on an ophthalmic lens, a plurality of spaced apart scattering centers sized and shaped to scatter light incident on the ophthalmic lens,
wherein the scattering centers are formed in a pattern such that each scattering center is the located at or near a corresponding array site of a two-dimensional array in which the spacing between array sites is a first distance, Dx, in one direction in a plane of the array and a second distance, Dy, in a second direction in the plane of the array, the second direction being orthogonal to the first direction,
wherein a center of each scattering center is displaced from a corresponding array site by an amount δx in the first direction and by an amount δy in the second direction, where

δx=Ax·Dx·RN[0,1], and

δy=Ay·Dy·RN[0,1],

wherein Ax and Ay are amplitudes that are between 0 and 1 and RN is a random number between 0 and 1.
