  • Patent number: 11982882
    Abstract: A system for the color coding of objects in the field of view of a plurality of spectacle wearers includes a pair of spectacles per spectacle wearer. Liquid crystal cells of at least one spectacle lens of the spectacles are so designed that a transmission (TR) of the liquid crystal cells may be switched between high and low transmission states. The system also includes one RGB light source per spectacle wearer and means for controlling or regulating the luminance times, color and intensity of the RGB light source such that the light source for a first spectacle wearer illuminates with a first color at a time of the state of high transmission of the liquid crystal cell and the light source for a second spectacle wearer illuminates at a time of high transmission of the liquid crystal cell of their spectacles with a second color different from the first.

  • Patent number: 11733548
    Abstract: The invention relates to spectacles, systems and methods for visibility enhancement, including by glare suppression. The spectacles, systems and methods for visibility enhancement includes spectacles and a spectacle lens having a liquid crystal cell (LC), the transmission (TR) of which may be varied by a suitable control and the liquid crystal cell (LC) designed so that the transmission (TR) of the liquid crystal cell (LC) may be switched between high and low transmission states.

  • Patent number: 10613352
    Abstract: The invention relates to spectacles, system and methods for visibility enhancement by glare suppression. The spectacles, system and methods for visibility enhancement by glare suppression includes a spectacle lens having a liquid crystal cell (LC) the transmission (TR) of which can be switched between transmitting and blocking. Furthermore, the spectacles comprise an eye tracker (ET) which can detect the viewing direction of the eye. spectacles, system and methods further include at least one sensor (IL, IR) for measuring the brightness of the visible light incident on it, said sensor being arranged on the eye side of the spectacle lens and measuring the brightness entering through the at least one spectacle lens in a spatially resolved manner. The sensor can determine the brightness of the visible light incident on it from the viewing direction of the eye detected by the eye tracker.

  • Patent number: 10444545
    Abstract: The invention relates to a system for visual enhancement. The system suppresses glare and includes a spectacle lens having a liquid crystal cell, the transmission of which can be switched between high and low transmission states. The system also includes at least one sensor for measuring the brightness of the visible light incident on it, the sensor being arranged on the eye side of the spectacle lens and measuring the brightness entering through the at least one spectacle lens. The system also includes a closed loop control circuit for regulating the transmission of the liquid crystal cell so that the times of the state of high transmission become shorter with increasing glare. The system includes a display for controlling the lighting times and the luminous intensity of the display during the state of high transmission of the liquid crystal cell.
