摘要：
A lens (200, 300), particularly a contact lens or intraocular lens, for improving the image quality of incident polychromatic light exhibiting wave front errors, comprising a central zone (201, 203; 301, 303, 306; 251) and at least one annular zone (201, 202; 301, 302; 250), is characterized in that positive or negative optical wavelength differences exist between adjoining zones (201, 202; 201, 203; 301, 302; 301, 303, 306; 250, 251) of the lens in the direction of the lens axis, said differences being at least as large as the coherence length of polychromatic light.
