    • The invention relates to spectacles. Said spectacles comprise 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. They further comprise 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. The spectacles also have a closed loop control system for controlling the transmission of the liquid crystal cell, a desired value for the brightness at the level of the eye being predetermined, and the closed loop system using the brightness measured by the sensor in the viewing direction of the eye as the actual value.
    • 本发明涉及眼镜。 所述眼镜包括具有液晶单元(LC)的眼镜片,透射(TR)可以在透射和阻挡之间切换。 此外,眼镜包括可以检测眼睛的观察方向的眼睛跟踪器(ET)。 它们还包括用于测量入射到其上的可见光的亮度的至少一个传感器(IL,IR),所述传感器布置在眼镜镜片的眼睛侧,并测量通过至少一个眼镜镜片进入的亮度 空间解决的方式。 传感器可以从眼睛跟踪器检测到的眼睛的观察方向确定入射到其上的可见光的亮度。 眼镜还具有用于控制液晶单元的透射的闭环控制系统,预定眼睛水平的亮度的期望值,以及使用传感器在观察方向上测量的亮度的闭环系统 的眼睛作为实际值。
