Abstract

See full text

A system of ophthalmic lenses contains a first lens for a first eye of a subject and a second lens for a second eye of a subject. The first lens includes a first lens shape having a first base refractive power and a first diffractive pattern imposed on the first lens shape, the diffractive pattern having a first lower diffraction order with a first lower diffractive power and a first higher diffraction order with a first higher diffractive power. The first lens includes lower and higher optical powers equal to the first base refractive power plus the first lower and higher diffractive powers, respectively. The second lens includes a second lens shape having a second base refractive power and a second diffractive pattern imposed on the second lens shape, the second diffractive pattern having a second lower diffraction order with a second lower diffractive power and a second higher diffraction order with a second higher diffractive power. The second lens includes lower and higher optical powers equal to the second base refractive power plus the second lower and higher diffractive powers, respectively. The first higher optical power has a negative LCA and the second lower optical power has a negative LCA. The second base refractive power does not equal either the second lower optical power or the higher optical power.
