Abstract

Spline surfaces can be formed at will. They are always twice continuously dif-ferentiable, i. e. they have no jumps, bends or ripples. In the automobile industry they are used in the design of car bodies for the minimization of air resistance. In the field of optics splines are employed for the spectacle lens, Gradal HS. The form of the spline surface is defined by optical requirements. Splines have contributed to the successful reduction to a minimum of the unavoidable aberrations present in progressive addition lenses and to the binocular equilibrium of the remaining aberrations. Conventional surface structures will be used as a comparison.
