Abstract

An anti-glare apparatus includes a lens assembly having an incident side, the lens assembly including a layer of liquid crystal molecules, a first driving electrode and a second driving electrode respectively on both sides of the layer of the liquid crystal molecules, the first driving electrode or the second driving electrode including a plurality of sub-electrodes; a reflective layer on a side of the lens assembly opposite from the incident side; a camera, configured to acquire a human eye's position and acquire an intensity signal of incident light irradiating the incident side of the lens assembly; and a controller electrically connected to the first driving electrode, the second driving electrode, and the camera; where the controller is configured to adjust driving voltages of the sub-electrode based on the intensity signal of the incident light acquire by the camera to change the optical axis direction of the lens assembly.
