Patent ID: 8308295

Claim:
An ophthalmic lens having a fitting point, comprising: a far distance zone having a far distance optical power; a mostly spherical power region on a front surface of the lens for providing additive optical power to the far distance optical power for providing an intermediate distance zone of the lens; a discontinuity, as viewed through the lens, located between the far distance zone and said mostly spherical power region; a progressive optical power region on a back surface of the lens that overlaps as viewed through the lens at least a portion of said mostly spherical power region for providing additive optical power to said mostly spherical power region, the progressive optical power region and the mostly spherical power region together providing a near distance zone of the lens; and a plateau of optical power located in a portion of said progressive optical power region for providing vertical stability of vision in said intermediate distance zone, wherein said mostly spherical power region and said progressive optical power region contribute to a total add power of the lens; and at least one of wherein: said plateau of optical power has a vertical length of approximately 1 millimeter to 3 millimeters, or said plateau of optical power has a vertical length of approximately 2 millimeter to 6 millimeters.
