  • Publication number: 20060139571
    Abstract: The lens presents horizontal prismatic refractive power that varies progressively along the main progression meridian (MM?) with the addition of horizontal prismatic power being greater than 2 prismatic diopters in absolute value, this addition of horizontal prismatic power being defined by the difference between the horizontal prismatic refractive power at the reference point (L) of the far vision zone and the horizontal prismatic refractive power at the projection point (P?) of the reference point (P) of the near vision zone (VP) on the vertical line passing through the reference point (L) of the far vision zone.

  • Patent number: 6789898
    Abstract: An ophthalmic lens having a complex surface and a toric or spherical surface is represented in a model using a prism reference point and a prescription point on the complex surface, the normal to the complex surface at the prism reference point, the local characteristics of the complex surface at the prescription point or around the prescription point, lens thickness measured along the axis defined by the normal to the complex surface, the plane tangential to the toric or spherical surface on the axis, and the curvatures of the toric or spherical surface. Representation of the lens in this model allows calculation of the toric or spherical surface without knowing all the characteristics of the complex surface. Calculations are simpler for the fitting of the lens into frames adapted to the wearer.
