Abstract: 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.

Abstract: A method for the determination of a progressive ophthalmic lens for a give n 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 axi al length of the wearer's eye. - calculating the power required on the lens for each direction of viewing b y successive iterations in order to obtain the target power defect and the target resulting astigmatism.

Abstract: The invention relates to an ophthalmic lens for long-sighted and intermediate vision comprising a complex surface provided with an optical centre, a substantially umbilicated meridian line and an average size sphere progression on the top surface equal to or greater than 0.50 diopters. The complex surface is provided in the top part thereof with a long-sighted vision area which is formed by cylinder points equal to or less than 0.25 diopters and covers an angular sector focused on the optical centre and whose angle is equal to 160°. Said complex surface also comprises an average size substantially constant sphere on the meridian line in the long-sighted vision area and a progression length equal to or less than 12 mm. Said progression length is defined as a vertical distance between the optical centre and a median point for which the average sphere if greater than 85% of progression on the average sphere in the optical centre. The inventive lens is suitable for driving and prescribed to persons having additional prescription greater than a power progression, whereby a correction adaptable to the power prescription of a longsighted vision person is provided in the top part of the lens. The lower part of the lens ensures the correction needed for an intermediate vision person.
