Multifocal ophthalmic lens

An ophthalmic lens configured to be inserted in or onto an individual's eye in order to provide vision correction over a wide range of viewing distances, the lens comprising:

• (a) a lens body having an optical axis and having an anterior face and a posterior face, one of said faces having first and second annular zones which are arranged in a concentric manner around said optical axis;
• and
• (b) means for providing in each of said first and second zones a first region having a first vision correction power and a second region having a second vision correction power which is significantly different from said first vision correction power, the vision correction power between the first and second optical powers being progressive.

A multifocal ophthalmic lens for providing variable vision correction power, said lens having first and second zones with the second zone lying radially outwardly of the first zone, each of said zones having a first region with near vision correction power, a second region with far vision correction power and an intermediate vision region between the first and second regions, the intermediate vision region including progressive intermediate vision correction powers which are intermediate the near vision correction power and the far vision correction power and which provide vision correction for intermediate distances.

An ophthalmic lens adapted to be carried by or in the eye for providing variable vision correction power, the corrective power being caused to vary progressively in a radial direction in an annular zone from a first vision correction value through an intermediate vision correction value to a second vision correction value and then back through the intermediate vision correction value to the first vision correction value and the intermeidate vision correction value being between the first and second vision correction value.

An ophthalmic lens adapted to be carried by or in the eye for providing variable vision correction power, the corrective power being caused to vary progressively in a radial direction in an annular zone from an intermediate vision correction power through a far vision correction power and a near vision correction power and then back to the intermediate vision correction power and the intermediate vision correction power being between the first and second vision correction powers.

A multifocal ophthalmic lens for providing variable vision correction power and adapted to be carried by the eye, said lens having a plurality of zones, the vision correction power of each of said zones varying progressively between a near vision correction value and a far vision correction value and then back toward an intermediate vision correction value, the intermediate vision correction value being between the near and far correction values.

An ophthalmic lens for providing variable vision correction power, said lens having a plurality of annular zones, the correction power of each of said zones varying progressively in a radial direction between a near vision correction power and a far vision correction power, and the correction power varying throughout each of said annular zones and in transition between each of said annular zones.
