摘要： A method for the determination of a progressive ophthalmic lens for a given wearer comprises the stages of: determining the axial length (LA) of the wearer's eye, determining an ergorama associating a sight point with each direction of viewing under wearing conditions. determining power and resulting astigmatism defect targets for each direction of viewing under wearing conditions, the targets being a function of the axial length of the wearer's eye. calculating the power required on the lens for each direction of viewing by successive iterations in order to obtain the target power defect and the target resulting astigmatism.

摘要： A method for the determination by optical optimization of a personalized progressive ophthalmic lens intended to be inserted into a frame chosen by a given wearer for whom a power addition has been prescribed in near vision, the method comprising the stages of: measuring parameters representing the frame chosen by the wearer; choosing an initial distribution of power and resulting astigmatism defect targets for each direction of viewing under wearing conditions in an ordinary frame; calculating transformation coefficients using the measured parameters representing the chosen frame and standard parameters; calculating a personalized distribution of the power and resulting astigmatism defect targets on the lens by applying the calculated transformation coefficients to the initial distribution. The method makes it possible to retain the proportion of the distribution between the far-vision, near-vision and intermediate-vision zones whatever the size and the shape of the frame chosen.
