    • The invention relates to a method for determining an ophthalmic lens for a person (i.sub.1, i.sub.2, i.sub.3) to wear said lens, comprising the following steps: i) determination of the size (T.sub.1, T.sub.2, T.sub.3) or height of the eyes (H.sub.1, H.sub.2, H.sub.3) of the person to wear the lens; and ii) calculation of at least one characteristic of the ophthalmic lens according to the size (T.sub.1, T.sub.2, T.sub.3) or the height of the eyes (H.sub.1, H.sub.2, H.sub.3) of the person to wear the lens. The ophthalmic lens can be progressive strength or unifocal. The invention also relates to an optimization method and a method for producing an ophthalmic lens implementing such a definition method. The invention further relates to a set of lenses having at least one characteristic that depends on the size and the height of the eyes of the person to wear the lens.
    • 本发明涉及一种用于确定人(i,1,i,2,i,3)佩戴所述镜片的眼科镜片的方法,包括以下步骤:i)确定尺寸( T.sub.1,T.sub.2,T.sub.3)或穿戴镜片的人的眼睛高度(H.sub.1,H.sub.2,H.sub.3); 和ii)根据大小(T.sub.1,T.sub.2,T.sub.3)或眼睛的高度计算眼科镜片的至少一个特征(H 1,H 2,H.sub.3)佩戴镜头的人。 眼科镜片可以是渐进的强度或单眼。 本发明还涉及一种实现这种定义方法的眼科镜片的优化方法和制造方法。 本发明还涉及一组具有取决于穿戴镜片的人的眼睛的尺寸和高度的至少一个特征的透镜。

    • An ophthalmic lens including: a prescription control point (P); an upper area having, relative to the point (P), and average-power continuous variation ΔPuiSup that is monotonous between the point (P) and the point (Psup) (maximum variation point in absolute value) where the signed value of the variation ΔPuiSupMax=Pui(Psup)−Pui(P) is between −0.1 and −0.4 dioptres; a lower area having, relative to the point (P), an average power continuous variation ΔPuinf that is monotonous between the point (P) and the point (Pinf) (maximum variation point in absolute value) where the signed value of the variation ΔPuiinfMax=Pui(Pinf)−Pui(P) is between +0.1 and +0.4 dioptres; the average power gradient being lower than 4.10−2×ΔPuitotal, where ΔPuitotal=|ΔPuisupMax|+ΔPuiInfMax. Such a lens advantageously takes the accommodative dynamics of the eye into account and increases the visual comfort of the wearer.
    • 一种眼科镜片,包括:处方控制点(P); 相对于点(P)的上部区域和在点(P)和点(Psup)(绝对值的最大变化点)之间单调的平均功率连续变化DeltaPuiSup,其中变化的符号值 DeltaPuiSupMax = Pui(Psup)-Pui(P)在-0.1和-0.4屈光度之间; 相对于点(P)的下部区域具有在点(P)和点(Pinf)(绝对值的最大变化点)之间单调的平均功率连续变化DeltaPuinf,其中变量DeltaPuiinfMax的有符号值 = Pui(Pinf)-Pui(P)在+0.1和+0.4屈光度之间; 平均功率梯度低于4.10-2×DeltaPuitotal,其中DeltaPuitotal = | DeltaPuisupMax | + DeltaPuiInfMax。 这样的透镜有利地考虑了眼睛的调节动力学并增加了佩戴者的视觉舒适度。

    • An ophthalmic lens (1) for a given wearer (2), intended to be worn in an eyeglass frame, comprising: a prescription control point P corresponding to a downward gaze αP of between −10° and +25° and a lateral gaze displacement βP of between −10° and +10°; an upper area (11) defined by downward gaze values, α, for the wearer (2), of between αP−30° and αP, along a downward gaze path, and by lateral gaze displacement values, β, for the wearer (2), of between βP−30° and βP+30°, parallel to a lateral gaze displacement axis, a lower area (12) defined by downward gaze values, α, for the wearer (2), of between αP and αP+30°, along a downward gaze path, and by lateral gaze displacement values, β, for the wearer (2), of between βP−30° and βP+30°, parallel to a lateral gaze displacement axis; wherein: the power of the lens at point P is substantially equal to the prescription of the wearer, the upper area has, relative to the point P, along the downward gaze path, a continuous average power variation ΔPuiSup, monotonic between the point P and a point PSup, which is the point of the maximum amplitude in the variation of the power value, as an absolute value, and where the value of the average power deviation between the points PSup and P, ΔPuiSupMax=Pui(PSup)−Pui(P), is between −0.1 and −0.4 dioptres, the lower area has, relative to the point P, along the downward gaze path, a continuous variation in the average power ΔPuiInf, monotonic between the point P and a point PInf, which is the point of the maximum amplitude in the variation of the power value, as an absolute value, and where the value of the average power deviation between the points PInf and P, ΔPujInfMax=Pui(PInf)−Pui(P), is between +0.1 and +0.4 dioptres, and the average power gradient along the downward gaze path is less than 4.10−2×ΔPuitotal, where ΔPuitotal=|ΔPuiSupMax|+ΔPuiInfMax and said average power gradient is expressed in dioptres per degree
