    Abstract: 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.

    Abstract: A refractor (100) includes: an enclosure having a front face containing a first optical window and a back face containing a second optical window aligned with the first optical window along an optical axis of observation; and at least one vision compensating device making it possible to observe along the optical axis of observation. The vision compensating device includes, between the first window and the second window, a first optical element having a spherical power along the optical axis, the spherical power being variable. The enclosure is mounted on an orientable holder (104) that is rotatable relative to a stationary portion (102) about a horizontal axis (H). A method for measuring refraction employing such a refractor is also disclosed.
