  • Optical observation instrument and a method of controllably adjusting a refractive power in such instrument
    Patent number: 8038296
    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.

  • Auto-focussing glasses and method for auto-focussing a pair of glasses
    Patent number: 7131725
    Abstract: A self-focussing spectacle as well as a method for self-focussing a spectacle are proposed. The spectacle comprises at least one spectacle lens of adjustable refracting power, and means for adjusting the refracting power of the spectacle lens as a function of a measured parameter representing a state of accommodation of a corresponding eye of a user of the spectacle. The means measure the refracting power of the eye directly.
