Patent abstract
A device and method for determining the defective vision of an optical system include a controllable optical element. The objective and subjective determination of the correction values are more greatly combined in that a measuring and controlling device forms a control loop with the controllable optical element, and the optical characteristics of the controllable element can be changed manually.
