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. The spectacles, methods and systems 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.
