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.
