Smart glass and a control method therefor. The smart glass comprises an LCD panel (104), an LCD drive module (103), a control module (101), a photosensitive module (106), a style storage module (105), and a communication module (102), wherein the control module (101) is configured to determine a light transmittance, a display mode and a display style of the LCD panel (104); and according to the light transmittance, the display mode and the display style, the control module (101) controls the LCD panel (104) to control the passing of light. Thus, the functions of a smart curtain and a smart sunshade film are realized, the problems in the prior art of an unsatisfactory effect of light regulation technology, space being occupied because of the use of shields such as a curtain, and the use thereof being inflexible and inconvenient are solved, the smart light control effect is improved, and a plurality of control modes are provided, which significantly improves the user experience.
