1. An anti-glare apparatus, comprising:
a lens assembly having an incident side, the lens assembly comprising 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, at least one of the first driving electrode or the second driving electrode comprising 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 an 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;
wherein the controller is configured to adjust the driving voltage of at least one of the sub-electrodes based on the intensity signal of the incident light acquire by the camera to change the optical axis direction of the lens assembly;
wherein the controller is configured to determine whether the intensity signal of the incident light is greater than a threshold value;
the controller adjusts the driving voltage of the at least one of the sub-electrodes to change the optical axis direction of the lens assembly in response that the intensity signal of the incident light is greater than the threshold value, and
the controller controls driving voltages of the plurality of sub-electrodes to remain unchanged in response that the intensity signal of the incident light is not greater than the threshold value;
wherein
the controller is further configured to control whether to change the optical axis direction of the lens assembly based on a combination of the intensity signal of the incident light and the human eye's position;
wherein
the controller is configured to determine whether the light intensity signal of the lens assembly is greater than the threshold value and whether the human eye's position is in a path of a reflected light of the incident light by the reflective layer;
the controller adjusts a driving voltage of the at least one of the sub-electrodes to change the optical axis direction of the lens assembly in response that the light intensity signal of the lens assembly is greater than the threshold value and the human eye's position is in the path of the reflected light of the incident light by the reflective layer; and
the controller controls the driving voltages of the sub-electrodes to remain unchanged in response that the light intensity signal does not reach the threshold, and/or the human eye position is not in the path of the reflected light;
wherein the anti-glare apparatus comprises a plurality of areas, each of the plurality of areas comprises the lens assembly, and an optical axis of the lens assembly of each of the plurality of areas is independently adjustable by the controller;
wherein the first driving electrode of the lens assembly of each of the plurality of areas comprises the plurality of sub-electrodes and the second driving electrode of the lens assembly of each of the plurality of areas merge into an integral driving electrode;
wherein the anti-glare apparatus comprises at least one camera in each of the plurality of areas, and the at least one camera in each area of the anti-glare apparatus is configured to acquire the intensity signal of the incident light of the lens assembly of the corresponding area.
