Multifocal ocular lens having intermediate-distance vision correction region formed in central part of vision correction area

摘要

A multifocal ocular lens having a vision correction area (12) including at least one distant vision correction region (16, 18) having a first optical power value for distant vision correction and at least one near vision correction region (16, 18) having a second optical power value for near vision correction, wherein the vision correction area (12) further includes a central intermediate-distance vision correction region (14) which has a third optical power value (Pa) for intermediate vision correction between the first and second optical power values (Pb, Pc) and which is located in a central portion of the vision correction area such that the distant and near vision correction regions (16, 18) are located radially outwardly of the central intermediate-distance vision correction region.
