METHOD FOR TAKING INTO CONSIDERATION DIFFERENT LONG-DISTANCE AND SHORT-DISTANCE PRISMATIC CORRECTIONS

摘要

The invention relates to a computer-implemented method, to a device for calculating or optimising a lens, and to a lens. Said method comprises the following steps: detecting a nominal optical power and/or a nominal astigmatism in a near reference point of the lens, determining a corrective value of the vertical and/or horizontal prism in the near reference point of the lens; modifying the nominal optical power and/or the nominal astigmatism in the near reference point on the basis of the corrective value of the vertical and/or horizontal prism of the lens; determining a continuous course of the nominal optical power and/or the nominal astigmatism along the main line of the lens on the basis of the modified optical power and/or nominal astigmatism in the near reference point; and calculating or optimising the lens on the basis of the modified nominal optical power and/or nominal astigmatism in the near reference point and the determined course of the nominal optical power and/or the nominal astigmatism along the main line.
