the photosensitive module 20 is configured to output a corresponding voltage value to the control module 30 according to ambient light;
the control module 30 is connected to the liquid crystal lens 40, and is configured to output a voltage signal to the liquid crystal lens according to the voltage value;
wherein, the charge retention rate of the liquid crystal lens 40 is more than 98%.
In the lens control system of sunglasses according to this embodiment, the liquid crystal lens with the charge retention rate greater than 98% is used as the spectacle lens, so that when the control module outputs a voltage to the liquid crystal lens, the charge of the liquid crystal lens moves to IT0 glasses at two ends of the liquid crystal lens, and the liquid crystal lens becomes a lens or a sunglass; since the liquid crystal lens can hold electric charges, the resistivity between the IT0 glasses at the two ends is high, so that the movement of the electric charges is hindered, and the liquid crystal lens can continuously keep the same state as that when the control module outputs the voltage.
Preferably, the control module 30 is an IC chip 4051, and the minimum operating voltage of the IC chip 4051 is 0.9V and the minimum operating current is 50 nA.
Because the working voltage of the IC chip 4051 is low, the lens control system of the sunglasses can use a battery with a smaller volume, thereby further reducing the influence of the battery on the appearance of the sunglasses to the maximum extent and improving the aesthetic degree of the sunglasses.
Preferably, the voltage signal output by the control module 30 to the liquid crystal lens 40 is a low-frequency alternating current voltage signal, and the frequency of the low-frequency alternating current voltage signal is 1/60Hz to 1/100 Hz.

Specifically, a threshold is preset in the IC chip 4051, and when the voltage value output by the photosensitive module 20 is greater than the threshold, the IC chip 4051 outputs a corresponding high voltage or low voltage to the liquid crystal lens.
In the lens control system of sunglasses according to this embodiment, a threshold is preset in the IC chip 4051, and when the voltage value output by the photosensitive module is greater than the threshold, the IC chip 4051 outputs a corresponding high voltage or low voltage to the liquid crystal lens, so that the liquid crystal lens can be instantly switched to the sunglasses state or the lens state when the liquid crystal lens moves from a place where light is strong to a place where light is weak or from a place where light is weak to a place where light is strong.
In this embodiment, the liquid crystal lens of the sunglasses adopts a liquid crystal lens in a negative display mode; therefore, when the voltage value output by the photosensitive module 20 is larger (i.e. the illumination intensity of the environment is strong) until the voltage value is greater than or equal to the threshold preset in the IC chip 4051, the control module 30 generates a voltage signal with a smaller value; when the voltage value output by the photosensitive module 20 is smaller (i.e. the illumination intensity of the environment is weak) until the voltage value is smaller than the threshold preset in the IC chip 4051, the control module 30 generates a voltage signal with a larger value.
Specifically, the IC chip 4051 is provided therein with a voltage boosting circuit for boosting the input voltage of the control module 30, so that the power supply module can operate as long as it is configured as a small low-voltage battery.
