1. A method for specifying image quality of an optical object having at least one optical surface, comprising:
obtaining at least one wave aberration of a tested optical object;
calculating at least one modulation transfer function from the obtained wave aberration of the tested object;
obtaining modulation transfer functions from a plurality of other optical objects that are similar to the tested optical obiect;
determining image quality of the tested object using a relative score system derived from the calculated modulation transfer function of the optical object and the obtained modulation transfer function from a plurality of optical objects that are similar to the tested optical object.
