Abstract
An optical observation instrument, in particular a spectacle, a reading aid or a telescope, comprises an optical element, in particular a spectacle lens, adapted to be controllably adjustable in its refractive power, a sensor, and a control unit for adjusting the refractive power as a function of signals from the sensor. The sensor is a brightness sensor. In a method of controllably adjusting a refractive power of an optical element in an optical observation instrument an optical parameter is captured by means of a sensor and the refractive power is adjusted as a function of a signal from the sensor. By means of the sensor the brightness of the light impinging on the optical instrument is captured.
