Abstract: An optical lens for a human eye is disclosed herein. In a described embodiment, the optical lens is in the form of a contact lens 100 which comprises a plurality of alternating optic zones 102 arranged between a centre 104 and a periphery 106 of the contact lens 100. The alternating optic zones 102 include a plurality of annular vision correction regions CZ1CZ5 having first refractive powers for correcting myopic refractive errors to create a focused retina image. The first refractive powers are more hyperopic at the lens' periphery 106 than at the lens' centre 104. The optic zones 102 further includes a plurality of annular vision defocus regions DZ1DZ5 having second refractive powers for creating a defocused retina image, wherein the plurality of annular vision defocus regions (DZ1DZ5) are arranged to alternate with respective ones of the plurality of annular vision correction regions (CZ1CZ5). With such a configuration, the contact lens 100 is useful for slowing myopia progression.
