Patent ID: 7004585

Claim:
An ophthalmic lens worn on the surface of an eye and having a blended design for a segmented optical zone, comprising an anterior surface and an opposite posterior surface, wherein the anterior surface includes a vertical meridian, a horizontal meridian, a central optical zone having at least a first optical zone for primary gaze, a second optical zone for down-gaze and an optical blending zone between the first and second optical zones, wherein the ophthalmic lens is characterized by having minimal or no ghost images or blur when transitioning between the first and second optical zones, wherein the first optical zone is located in the upper portion of the central optical zone and the second optical zone is located in the lower portion of the central optical zone, wherein the optical blending zone has a surface that ensures a smooth surface transition from the first optical zone to the second optical zone and that allows the first and second optical zone to be designed independently and optimally so that ghost images or blur from the first and second optical zones is minimized or eliminated, wherein the apex of first optical zone coincides with the center of the central optical zone, wherein the vertex center of the second optical zone is located at the intersection point of the vertical meridian or a line which is parallel to the vertical meridian and passes through the center of the central optical zone with its boundary line with the optical blending zone, and the distance between the vertex center of the second optical zone and the apex of the first optical zone is 1.5 mm or less.
