OPHTHALMIC LENSES INCORPORATING A DIFFRACTIVE ELEMENT

摘要

An ophthalmic lens (100) is provided that comprises a correction lens having a first focal region (110) having a first focal power and a second focal region (122) having a second focal power different from the first power. The ophthalmic lens further comprises a diffractive element (120) having a diffractive element focal power that is additive to the second focal power. In some embodiments, the second focal power is a multi-focal region that may be a progressive addition region or an electro-active region.
