  • ADJUSTING OPTICAL PROPERTIES OF GLASSES USING ADAPTIVE OPTICS AND SENSORS
    Publication number: 20250035963
    Abstract: Techniques involve a smartglasses device having sensors, processing circuitry, and a lens including an adaptive optical device. The processing circuitry is configured to receive, from the sensors, an indication that a context of the wearer has changed. In response to such an indication, the processing circuitry adjusts a voltage applied to the adaptive optical device. In some implementations, the adaptive optical device includes a liquid crystal optic that is configured to change an optical power of the lens in response to a change in applied voltage. In this way, the smartglasses device enables a wearer to see clearly in a variety of contexts without any manual adjustment of the frame or lenses.
