VISUAL COMPENSATION DEVICE, METHOD FOR CONTROLLING VISUAL COMPENSATION DEVICE, AND BINOCULAR OPTOMETRY DEVICE

摘要

A visual compensation device making it possible to observe an observation optical axis (X) with an optical correction of variable power, comprises a lens (6) having, according to the optical axis, a variable spherical power as a function of a first control, and an optical assembly (2, 4) generating, along the optical axis, a cylindrical correction variable according to at least a second command applied to said optical assembly (2, 4). The visual compensation device also comprises a module for receiving at least one setpoint for said optical correction and a module for determining the first command and the second command according to said setpoint by means of a model taking account of the distance (e2) separating said lens (6) and said optical assembly (2, 4). A control method of a visual compensation device and a binocular optometry device are also provided.
