    • The invention relates to a device for determining the center of rotation of an eye of a person relative to a frame of reference associated with the person or with said person's eyeglasses, making it possible to determine the visual axis of the person along at least two non-parallel directions by viewing a target, and to define an optimum point of intersection of said axes as the center of rotation of the eye, at least two relative positions of said target and of the person's head being measured. In the invention, said target is constituted by a light source and is disposed at one end of a tubular support, with the other end being for disposing facing the person's eye, the support carrying a first position sensor, a second position sensor being for placing on the person's head.
    • 本发明涉及一种用于确定人的眼睛相对于与该人或与该人的眼镜相关联的参考框架的旋转中心的装置,使得可以沿着至少两个非视觉角度来确定该人的视轴, 通过观察目标的平行方向,并且将所述轴的最佳交叉点定义为眼睛的旋转中心,测量所述目标和人的头部的至少两个相对位置。 在本发明中,所述目标由光源构成,并且设置在管状支撑体的一端,另一端用于面对人的眼睛,所述支撑件承载第一位置传感器,第二位置传感器用于放置 在人的头上。

    • An ophthalmic lens (10) comprises an optical component (1) and a layer (2) placed on a face of the optical component (1a). The layer (2) has a variable refractive index and is structured so that a second order derivative of the index with regard to a linear spatial coordinate along the face of the optical component (1a) is greater than a fixed threshold. The layer (2) makes it possible to alter the optical power and astigmatism of the lens (10) with regard to corresponding values only relative to the optical component (1). In the event that the ophthalmic lens (10) is a progressive lens, the layer (2) makes it possible to change an addition, a length of progression and/or a design of the progressive lens.
    • 一种眼用透镜(10)包括光学部件(1)和放置在光学部件(1a)的表面上的层(2)。 层(2)具有可变折射率,并且被构造成使得沿着光学部件(1a)的面的​​关于线性空间坐标的折射率的二阶导数大于固定阈值。 相对于相对于光学部件(1)的对应值,层(2)使得可以改变透镜(10)的光焦度和散光。 在眼镜(10)是渐进镜片的情况下,层(2)可以改变渐进镜片的相加,渐进长度和/或设计。
