摘要： A progressive ophthalmic lens including a far vision zone, a near vision zone and an intermediate vision zone is provided having a relatively high, relatively wide near vision zone and a relatively wide intermediate zone. A surface correction(s) for reducing optical aberrations in peripheral regions of the lens may be provided within a pair of generally horizontally disposed opposed segments approximately ±22.5° above and below a generally horizontally axis passing through a fitting cross. Two or more progress ophthalmic lenses differing in prescribed addition power may be placed in series to provide a range of distance prescriptions for one or more of emmetropes, hyperopes and myopes. A method of designing the progressive ophthalmic lens is also disclosed.

摘要： A progressive ophthalmic lens element having a front surface that includes an upper viewing zone having a surface power suitable for distance vision, a lower viewing zone having a surface power suitable for near vision, and a corridor of relatively low astigmatism connecting the upper and lower viewing zones, the corridor being a part of an intermediate viewing zone having a surface power varying from that of the upper viewing zone to that of the lower viewing zone. The progressive ophthalmic lens element also has a back surface. The invention is then characterized by the front surface including at least one correction to improve optical performance of the lens element by at least partially compensating for a cylinder correction applied to, or to be applied to, the backsurface.

摘要： A progressive ophthalmic lens element is disclosed. The progressive ophthalmic lens element includes an upper viewing zone, a lower viewing zone, a corridor, and a peripheral region disposed on each side of the lower viewing zone. The upper viewing zone includes a distance reference point (DRP) and a fitting cross, and provides a first refractive power for distance vision. The lower viewing zone, which is for near vision, provides an addition power relative to the first refractive power. The corridor connects the upper and lower zones and provides a refractive power varying from that of the upper viewing zone to that of the lower viewing zone. Each peripheral region includes a zone of positive power relative to the addition power which provides therein a positive refractive power relative to the refractive power of the lower viewing zone. The zones of relative positive power are disposed immediately adjacent to the lower viewing zone such that the lower viewing zone interposes the zones of relative positive power.

摘要： An ophthalmic lens element is disclosed. The lens element includes a front surface and a rear surface, at least one which includes a horizontal meridian and a vertical meridian. A central region of the lens element includes a foveal vision zone providing a first power for providing clear foveal vision for a wearer. A peripheral region of positive power relative to the first power is also included. The peripheral region includes dual progressive zones located bilaterally of the vertical meridian and extending radially outwardly from the central region. The lens element provides a distribution of surface astigmatism which provides, on the horizontal meridian, a relatively low surface astigmatism in the central region and the progressive zones.
