    Abstract: Cette lentille optique est caractérisée en ce que la courbe représentative de sa proximité P, définie comme étant égale à l'inverse de la distance D à laquelle un rayon lumineux parallèle à son axe et de hauteur h par rapport à celui-ci recoupe cet axe, s'inscrit dans une zone comprise entre une courbe enveloppe inférieure (Pinf) et une courbe enveloppe supérieure (Psup) répondant aux équations suivantes : Pinf = f(h) = ( .SIGMA. A'i hi ) + PVL Psup = f(h) = ( .SIGMA. A"i hi ) + PVL dans lesquelles PVL est la proximité en vision de loin et A'i, A"i des coefficients numériques dépendant de l'addition de proximité ajoutée en vision de près à la proximité en vision de loin. Application à la réalisation de lentilles de contact, d'implants intra-oculaires, ou de lentilles intra-cornéennes pour presbytes.

    Abstract: This relates to an opthalmic lens of the type in which, for the definition of two separate vision zones, one, (ZVL), corresponding to far vision and the other, (ZVP), corresponding to near vision, the curve representing the power as a function of the height h with respect to the axis (A) lies within a zone between a lower envelope curve and an upper envelope curve satisfying specified polynomial equations in which the coefficients depend on the addition of power corresponding to the degree of presbyopia of the wearer. According to the invention, either of the two vision zones (ZVL or ZVP) is enhanced with respect to the other, the corresponding areas SVL, SVP being related to each other by the following relationship: for enhanced near vision: 1.8
