In many cases, the refractive focusing power provided by the lens's central 10 region corresponds to a far-focusing power that is substantially equal to one of the diffractive focusing powers while the other diffractive power corresponds to a nearfocusing power. As such, in m:ny cases, the focusing properties of the lenses are dominated by the far-focus ability, especially for small pupil sizes. 1651525.3it0,
