The initial state of the liquid crystal glasses after being electrified is set to be an eye protection mode, and the control method of the eye protection mode comprises the steps of touching two touch pads from back to front, and increasing the blackness of a liquid crystal lens;
The method comprises the steps of touching at least one touch pad for a set time, switching the eye protection mode into a training mode, and alternately blackening and transparentizing the liquid crystal lens under the control of the MCU in the training mode, wherein the method specifically comprises the steps of touching two touch pads from back to front, keeping the blackness of the liquid crystal lens unchanged, increasing the flicker frequency of the liquid crystal lens, and touching two touch pads from front to back, keeping the blackness of the liquid crystal lens unchanged and reducing the flicker frequency of the liquid crystal lens.
Wherein the set time is 1S-10S.
The step of touching the two touch pads from back to front sequentially increases blackness of the liquid crystal lens, and specifically comprises the following steps:
When the liquid crystal display device slides forwards, fingers sequentially pass through two non-adjacent touch PADs PAD2 and PAD1 in the touch interface from back to front, the two touch PADs sequentially generate capacitors to the mode switching controller, pins P13 and P12 of the mode switching controller sequentially output low-level signals to the MCU, the MCU judges that the liquid crystal display device slides forwards according to the detected low-level signals of the two PADs, after the MCU receives the forward sliding signals, the PWM16 function of the MCU is enabled and the regulated CLK and DAT pins output waveforms (as shown in fig. 4), so that the time of a waveform (as shown in fig. 4) Ton obtained on a liquid crystal lens is increased, the time of Toff is reduced (wherein the total time of ton+toff is not changed.1000/(ton+toff) =24-250, and the total time of on a liquid crystal lens is increased in unit time after the time of ton+toff is reduced, so that the blackness of the lens is increased.
The step of touching the two touch pads from front to back sequentially reduces blackness of the liquid crystal lens, and specifically comprises the following steps:
When the MCU slides backwards, fingers sequentially pass through two non-adjacent touch PADs PAD1 and PAD2 in the touch interface from front to back, the two touch PADs sequentially generate capacitors to the mode switching controller, pins P12 and P13 of the mode switching controller sequentially output low-level signals to the MCU, the MCU judges that the MCU slides backwards according to the detected low-level signals of the two PADs, after the MCU receives the forward sliding signals, the PWM16 function of the MCU is enabled and the regulated CLK and DAT pins output waveforms (as shown in fig. 4), so that the time of a waveform (as shown in fig. 4) Toff obtained on a liquid crystal lens is increased, the time of Ton is reduced, wherein the total time of ton+toff is unchanged, 1000/(ton+toff) =24-250, the total time of Toff is increased under the condition that the total time of ton+toff is unchanged (flicker frequency is unchanged), and the total time of Ton, which is turned off in unit time is increased, and the effect of reducing the blackness of the lens is achieved.

The polarizer of the liquid crystal lens adopts the UV-proof polarizer, and the substrate adopts the blue-proof coating on the TAC substrate, so that the UV and blue light can be prevented.
In the eye protection mode, when the time for touching the right glasses leg is longer than the set time (the set time is 1S-10S), the sensing capacitor generated by the right glasses leg is transmitted to the mode switching controller, the mode switching controller outputs low level to the low-power consumption MCU after receiving the sensing capacitor, the MCU executes a conversion instruction after receiving the signal, and the working mode is switched from the eye protection mode to the training mode:
The liquid crystal lens flashes at a frequency of 1-23 times per second in the training mode, and the time (ton+toff) of blackening and transparentizing of the lens can be adjusted each time of flashing, and the response speed of eyes and the intensity of eye muscle training can be trained in stages by adjusting the time of blackening and transparentizing and the flashing frequency.

Method for adjusting darkening and transparence retention time:
In the training mode, when a finger touches the right glasses leg in a short touch mode, the finger does not slide backwards or forwards, two bonding pads in a touch interface of the mode switching controller generate induction capacitance simultaneously or generate induction capacitance singly and then output the induction capacitance to the mode switching controller, a pin of the mode switching controller outputs a corresponding low-level signal to be transmitted to the MCU, and the MCU judges that the touch is short according to the received signal. Then the MCU enables the PWM16 function and adjusts the CLK and DAT pins to output waveforms (as shown in FIG. 4), so that the time distribution ratio of the waveforms (as shown in FIG. 4) Ton and Toff obtained on the liquid crystal lens is correspondingly adjusted. For each touch, ton increases and Toff decreases (the sum ton+toff is constant), and loops back to the minimum value after Ton increases to the maximum, and loops back. Under the condition that the total ton+toff is unchanged, the time distribution ratio of Ton and Toff is adjusted, so that the residence time of the lens for blackening and transparentizing can be adjusted under the condition that the flicker frequency of the lens is unchanged.
When used as a reaction rate for athletes training eyeglasses,
In the first stage, the flicker frequency of the lens is adjusted to be 5HZ (flicker 5 times per second), and the retention time of blackening and transparentizing of the lens is 1:2.
In the second stage, under the condition that the flicker frequency of the lens is 5HZ (flicker is 5 times per second), the stay time for blackening and transparentizing is adjusted to be 1:1, the blackening time is increased, and the time for preventing people from seeing an external scene is prolonged, so that the ball feeling of a training player for catching and pitching is achieved.
And in the third stage, under the condition that the flicker frequency of the lens is 5HZ (5 times of flicker per second) and is unchanged, the stay time for blackening and transparentizing is adjusted to be 2:1, the blackening time is further increased, the time for preventing people from seeing an external scene is further increased, and therefore the ball feeling of a player for catching and pitching is further trained.
And in the fourth stage, the flicker frequency of the lens is adjusted from 5HZ to 10HZ (flicker 10 times per second), so that the flicker frequency of an external scene seen by the eyes of a person is increased, and the response speed of the eyes is further trained.
