视觉补偿装置、控制视觉补偿装置的方法及双眼验光装置
摘要：
本发明提供了一种允许沿观察光轴(X)以焦度可变的光学矫正进行观察的视觉补偿装置，所述视觉补偿装置包括：镜片(6)，所述镜片沿所述光轴具有根据第一控制可变的球镜度；以及光学组件(2，4)，所述光学组件沿所述光轴产生根据应用到所述光学组件(2，4)的至少一个第二控制可变的柱镜矫正。所述视觉补偿装置还包括用于接收所述光学矫正的至少一个设定点的模块、以及用于根据所述设定点借助于考虑到所述镜片(6)与所述光学组件(2，4)分离开的距离(β2)的模型来确定所述第一控制和所述第二控制的模块。还提出了一种用于控制视觉补偿装置的方法以及一种双眼验光装置。
摘要（英）：

A vision-compensating device allowing observation along an optical axis of observation with an optical correction of variable power includes a lens having, along the optical axis, a spherical power that is variable as a function of a first control, and an optical assembly generating, along the optical axis, a cylindrical correction that is variable as a function of at least one second control applied to the optical assembly. The vision-compensating device also includes a module for receiving at least one setpoint for the optical correction and a module for determining the first control and the second control depending on the setpoint by way of a mode taking into account the distance separating the lens and the optical assembly. A method for controlling a vision-compensating device and a binocular optometry device are also proposed.
