Description
Technical Field
[0001] The present invention relates to the technical field of glasses, and in particular to a pair of liquid crystal glasses with the functions of alleviating eye fatigue and visual training and a control method thereof. Background Art
[0002] In recent years, with the general improvement of people's living standards, electronic office and electronic products have become more and more popular. The application of electronic products has shown two characteristics: a large population and a trend of younger age. As a result, there are more and more eye problems. Statistics show that the incidence of myopia among primary school students has reached 40%. The incidence of dry eye, visual fatigue, cataracts, macular degeneration and other diseases in adults has increased year by year. How to avoid damage to the eyes caused by electronic products is an important health issue that people in modern society need to pay attention to.
[0003] Dry eyes and fatigue can lead to decreased visual quality and even induce keratitis. The front of a normal person's eye is the cornea, and there is a layer of tear film on the surface of the cornea, which is used to sterilize, protect, moisturize and nourish the cornea. A normal person blinks once every 4-6 seconds, and the tear film breaks up in more than 10 seconds. If the eyes are stared at the electronic screen for a long time, the number of blinks and eye movements will decrease. If the environment, temperature, humidity and other factors are added, the tear film will be incomplete and uneven, the corneal surface will lose moisture and protection, and symptoms of dry eyes such as dry eyes, fatigue, and foreign body sensation will appear. If dry eyes are not treated, the ocular surface will continue to be deprived of the moisturizing and sterilizing effects of tears, and eventually become irreversible dry eye disease, affecting visual function, resulting in decreased visual quality, and keratitis in severe cases.
[0004] Mobile phone screens and LED screens contain a lot of blue light, which is a high-energy short-wavelength light source second only to ultraviolet rays. It has strong penetrating power on eye tissues and can penetrate the front cornea and lens directly to the retina. The chronic damage of these short-wavelength lights to the retina is the main cause of age-related macular degeneration.
[0005] However, existing glasses can only block part of the harmful light and cannot achieve the effect of training vision and relieving eye fatigue. Therefore, it is necessary to provide a pair of glasses with the function of relieving eye fatigue to solve the above technical problems. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0043] The purpose of the present invention is to provide a liquid crystal glasses with the function of relieving eye fatigue and visual training and a control method thereof, which realizes eye protection mode and training mode by adjusting the brightness and flashing frequency of the liquid crystal lenses, and has multiple functions such as relieving eye fatigue and visual training.
[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0045] like Figures 1 to 9 As shown, the liquid crystal glasses with the functions of relieving eye fatigue and visual training provided by the present invention include a frame 1 and two temples 2 which are hingedly connected, the frame 1 is embedded with a liquid crystal lens 8, the temples 2 are hinged with the frame 1 and are embedded with magnets 4, the corresponding positions of the pile heads of the frame 1 are provided with magnetic sheets, and a magnetic connection structure is formed with the magnets, and the two temples 2 are both provided with mounting cavities, wherein an integrated circuit board 6 is provided in the mounting cavity of the right temple, and a power switch controller 3 and a micro battery electrically connected to the power switch controller 3 are provided in the mounting cavity of the left temple;
[0046] The integrated circuit board 6 includes a charging controller, an MCU, and a linear regulator and a mode switching controller electrically connected to the MCU. The linear regulator is electrically connected to the power switch controller 3 through an FPC soft flat cable passing through the frame, the power switch controller is electrically connected to the charging controller through an FPC soft flat cable passing through the frame, the mode switching controller is electrically connected to the linear regulator, and the mode switching controller is electrically connected to a touch interface 5, and the touch interface 5 is provided with two non-adjacent touch pads; the liquid crystal lens 8 is electrically connected to the MCU, and the MCU controls the brightness and flickering frequency of the liquid crystal lens 8;
[0047] When the temples are opened, the magnetic sensing surface of the power switch controller 3 is opposite to the magnet 4 and the distance is within 4 MM. The power switch controller 3 can sense the magnetic field generated by the magnet. After the power switch controller 3 senses the magnetic field generated by the magnet 4, the power switch controller 3 is turned on, and the power supply of the micro battery 9 is input to the linear regulator. After voltage stabilization, the stable output voltage is sent to the MCU and the mode switching controller, providing a stable power supply voltage for the two devices.
[0048] The temple is also provided with a charging controller electrically connected to the battery, and the charging controller is connected to a USB interface 7 .
[0049] The micro battery 9 is a polymer lithium ion battery.
[0050] The MCU is selected as BL23M1610, the mode switching controller is selected as TC332, the linear regulator is selected as BL8064, the charging controller is selected as BL4054, and the power switch controller is selected as A3212.
[0051] The liquid crystal lens 8 is made of glass or a flexible TN / STN twisted nematic liquid crystal lens. The polarizer on the lens is an anti-UV polarizer. The hardened film on the lens is made of TAC or nylon material with an anti-blue light layer.
[0052] like Figure 10 to Figure 11 As shown, the present invention also provides a control method for liquid crystal glasses with the functions of relieving eye fatigue and visual training, which is applied to the above-mentioned liquid crystal glasses with the functions of relieving eye fatigue and visual training, and comprises the following steps:
[0053] The initial state of the liquid crystal glasses after power-on is set to an eye protection mode, and the control method of the eye protection mode includes: touching the two touch pads from back to front successively, the blackness of the liquid crystal lens increases; touching the two touch pads from front to back successively, the blackness of the liquid crystal lens decreases;
[0054] When at least one of the touch pads is touched for a set time, the eye protection mode is switched to the training mode. In the training mode, the liquid crystal lens turns black, becomes transparent and flickers alternately under the control of the MCU, specifically including: touching two of the touch pads from back to front, the blackness of the liquid crystal lens remains unchanged, and the flickering frequency of the liquid crystal lens increases; touching two of the touch pads from front to back, the blackness of the liquid crystal lens remains unchanged, and the flickering frequency of the liquid crystal lens decreases.
[0055] The setting time is 1S to 10S.
[0056] The step of touching the two touch pads in sequence from back to front to increase the blackness of the liquid crystal lens specifically includes:
[0057] When sliding forward, the finger passes through two non-adjacent touch pads PAD2 and PAD1 in the touch interface from back to front. The two touch pads generate capacitance to the mode switching controller. The pins P13 and P12 of the mode switching controller output low-level signals to the MCU. The MCU determines that it is sliding forward based on the low-level signals detected from the two pads. When the MCU receives the forward sliding signal, it enables the PWM16 function of the MCU and adjusts the output waveform of the CLK and DAT pins (such as Figure 4 ), so that the waveform obtained on the liquid crystal lens (such as Figure 4 ) The time of Ton increases, and the time of Toff decreases (wherein the total time of Ton+Toff remains unchanged. 1000 / (Ton+Toff)=24~250. Under the condition that the total time of Ton+Toff remains unchanged (the flickering frequency remains unchanged), the time of Ton increases and the time of Toff decreases, the total time that the liquid crystal lens is lit per unit time increases, thereby achieving the effect of increasing the blackness of the lens.
[0058] Touching the two touch pads successively from front to back, so that the blackness of the liquid crystal lens decreases, specifically includes:
[0059] When sliding backward, the finger passes through two non-adjacent touch pads PAD1 and PAD2 in the touch interface from front to back, and the two touch pads generate capacitance to the mode switching controller. The pins P12 and P13 of the mode switching controller output low-level signals to the MCU in succession. The MCU determines that it is sliding backward based on the low-level signals detected from the two pads in succession. When the MCU receives the signal of sliding forward, it enables the PWM16 function of the MCU and adjusts the output waveform of the CLK and DAT pins (such as Figure 4 ), so that the waveform obtained on the liquid crystal lens (such as Figure 4)Toff time increases, Ton time decreases, wherein the total time of Ton+Toff remains unchanged, 1000 / (Ton+Toff)=24~250. Under the condition that the total time of Ton+Toff remains unchanged (flickering frequency remains unchanged), after the time of Toff increases and the time of Ton decreases, the total time that the liquid crystal lens is closed per unit time increases, thereby achieving the effect of reducing the darkness of the lens.
[0060] in,
[0061] ①The unit of Ton and Toff is ms (milliseconds);
[0062] ②Ton is the high level time added to the liquid crystal lens. When the level is high, the liquid crystal lens is lit. Toff is the low level time added to the liquid crystal lens. When the level is low, the liquid crystal lens is turned off.
[0063] ③Ton+Toff is a conversion cycle, the total number of cycles converted within 1 second is the flashing frequency, and the flashing frequency is controlled at 24HZ~250HZ, that is: 1000 / (Ton+Toff)=24~250, (1 second=1000 milliseconds);
[0064] ④ When the flicker frequency is lower than 24HZ, the human eye can feel it. When it is greater than 24HZ, the human eye cannot feel the flicker. When it is greater than 250HZ, the power consumption of the liquid crystal lens will increase and affect the display blackness. Therefore, the flicker frequency range is 24HZ ~ 250HZ.
[0065] The eye protection mode can be used for daily use when watching electronic products, which can prevent UV and blue light, and protect the eyes from UV and blue light damage. Since the polarizer of the liquid crystal lens is a UV-proof polarizer, and the substrate is a TAC substrate with an anti-blue light coating, it can prevent UV and blue light.
[0066] In the eye protection mode, when the right temple is touched for a time greater than the set time (the set time is 1S-10S), the inductive capacitance generated by the right temple is transmitted to the mode switching controller. After receiving the inductive capacitance, the mode switching controller outputs a low level to the low-power MCU. After receiving the signal, the MCU executes the conversion instruction and switches the working mode from the eye protection mode to the training mode:
[0067] In training mode, the liquid crystal lens flashes at a frequency of 1 to 23 times per second, and the time it takes for the lens to turn black and transparent (Ton + Toff) can be adjusted for each flash. By adjusting the time it takes to turn black and transparent and the flashing frequency, the reaction speed of the eyes and the intensity of eye muscle training can be trained in stages.
[0068] Methods for adjusting and achieving a flashing frequency of 1 to 23 times per second:
[0069] When adjusted to the training mode, by sliding the right temple, the inductive capacitance generated by the right temple is transmitted to the mode switching controller. After receiving the inductive capacitance, the mode switching controller outputs a low level to the low-power MCU. After receiving the signal, the MCU executes the frequency conversion instruction.
[0070] In the training mode, the liquid crystal lens turns black, becomes transparent and flashes alternately under the control of the MCU. When the lens turns black, the human eye cannot see the external scene, and when the lens turns transparent, the external scene can be seen clearly.
[0071] Among them, when the two touch pads are touched successively from back to front, the blackness of the liquid crystal lens remains unchanged and the flickering frequency of the liquid crystal lens increases, specifically including:
[0072] When sliding forward, the finger passes through two non-adjacent touch pads PAD2 and PAD1 in the touch interface of the mode switching controller from back to front, and the two touch pads generate capacitance to the mode switching controller in turn. The pins P13 and P12 of the mode switching controller output low-level signals to the MCU in turn. The MCU determines that it is sliding forward based on the low-level signals detected from the two pads in turn. When the MCU receives the signal of sliding forward, it enables the PWM16 function of the MCU and adjusts the output waveforms of the CLK and DAT pins (such as Figure 4 ), so that the waveform obtained on the liquid crystal lens (such as Figure 4 )T-frame (Ton+Toff) time is reduced, Ton and Toff are reduced by the same unit, so as to achieve the effect of unchanged lens blackness and increased lens flickering frequency, flickering frequency = 1000 / T-frame.
[0073] Touching the two touch pads successively from front to back, the blackness of the liquid crystal lens remains unchanged and the flickering frequency of the liquid crystal lens decreases, specifically includes:
[0074] When sliding backward, the finger passes through two non-adjacent touch pads PAD1 and PAD2 in the touch interface of the mode switching controller from front to back, and the two touch pads generate capacitance to the mode switching controller. The pins P12 and P13 of the mode switching controller output low-level signals to the MCU in succession. The MCU determines that it is sliding backward based on the low-level signals detected from the two pads in succession. When the MCU receives the signal of sliding forward, it enables the PWM16 function of the MCU and adjusts the output waveforms of the CLK and DAT pins (such as Figure 4 ), so that the waveform obtained on the liquid crystal lens (such as Figure 4 )T-frame (Ton+Toff) time increases, Ton and Toff increase by the same unit, so as to achieve the effect of unchanged lens blackness and reduced lens flickering frequency, flickering frequency = 1000 / T-frame.
[0075] Method to adjust the blackening and transparent dwell time:
[0076] In the training mode, when the finger touches the right temple in a short touch mode without sliding backward or forward, the two pads in the touch interface of the mode switching controller generate sensing capacitance at the same time or generate sensing capacitance individually and then output it to the mode switching controller. The mode switching controller pin outputs the corresponding low-level signal to the MCU. The MCU determines it as a short touch based on the received signal. Then the MCU enables the PWM16 function and adjusts the CLK and DAT pin output waveforms (such as Figure 4 ), so that the waveform obtained on the liquid crystal lens (such as Figure 4 ) The time distribution ratio of Ton and Toff is adjusted accordingly. Each time you touch, Ton increases and Toff decreases (the sum of Ton + Toff remains unchanged). When Ton increases to the maximum, it cycles to the minimum again, and then cycles again. Under the condition that the sum of Ton + Toff remains unchanged, by adjusting the time distribution ratio of Ton and Toff, the residence time of the lens turning black or transparent can be adjusted while the lens flashing frequency remains unchanged.
[0077] When used as a training glasses reaction speed for athletes,
[0078] In the first stage, the flashing frequency of the lens is adjusted to 5HZ (5 flashes per second), and the residence time of the lens turning black and transparent is 1:2.
[0079] In the second stage, the flashing frequency of the lens remains unchanged at 5HZ (5 flashes per second), and the dwell time of turning black and transparent is adjusted to 1:1, increasing the blackening time so that the human eye cannot see the external scenery for a longer time, thereby training athletes to catch and throw the ball.
[0080] In the third stage, while the flashing frequency of the lens remains unchanged at 5HZ (5 flashes per second), the dwell time between blackening and becoming transparent is adjusted to 2:1, further increasing the blackening time and further increasing the time that the human eye cannot see the outside world, thereby further training the athletes' sense of catching and throwing the ball.
[0081] In the fourth stage, the flashing frequency of the lens is adjusted from 5HZ to 10HZ (flashing 10 times per second), which increases the flashing frequency of external scenes seen by the human eye and further trains the reaction speed of the eyes.
[0082] The liquid crystal glasses with the functions of relieving eye fatigue and visual training provided by the present invention and the control method thereof adopt liquid crystal lenses that are UV-proof and blue-light-proof, and the flashing frequency and blackness of the liquid crystal lenses can be controlled by hardware circuits in combination with software; after wearing, UV and blue light can be protected, and the eye muscles can be trained by the flashing of the lenses, so that the eye muscles are well exercised, especially the blackness adjustment function of the lenses, which is more suitable for patients with cataracts and eye diseases to wear after surgery (patients with cataracts and eye diseases are afraid of light, and wearing ordinary sunglasses cannot meet everyone's needs in terms of blackness). The present application can adjust different blackness according to the different degrees of photophobia of different patients to adapt to different patients; in addition, in the training mode, the flashing function of the glasses can also be used to train the reaction speed and ball sense of the human eye, and is suitable for athletes such as basketball, tennis, and baseball, or people who need to improve the reaction speed and ball sense of the human eye.
[0083] Among them, first, wear when watching electronic products: when watching the screen of electronic products, wear this pair of glasses and adjust to the eye protection mode, which can block the blue light emitted by electronic products. When watching electronic products for a long time and the glasses are tired, adjust to the training mode to exercise the eye muscles and relieve eye fatigue; second, basketball, tennis, baseball and other athletes wear them. When basketball, tennis, baseball and other athletes need to improve the reaction speed of their eyes, wear these glasses and adjust to the training mode. In this mode, the lenses set eye obstacles for the athletes at a frequency of 1 to 23 times per second. In this way, the athletes' eye reaction speed is trained to improve the hit rate. Athletes at different stages can gradually improve the reaction speed of the glasses by setting different flashing frequencies and the time for blackening and becoming transparent when flashing; third, patients with eye diseases can wear them after surgery. Patients with eye diseases are afraid of light after surgery and usually need to wear sunglasses. However, patients at different stages have different degrees of photophobia. The best way to wear glasses is to adjust the darkness of the lenses according to the different degrees of photophobia of the patients to adapt to different patients with eye diseases and different stages of rehabilitation of the patients.

The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.

The integrated circuit board includes a charging controller, an MCU, and a linear regulator and a mode switching controller electrically connected to the MCU, the linear regulator and the power switch controller are electrically connected through an FPC soft flat cable passing through the frame, the power switch controller and the charging controller are electrically connected through an FPC soft flat cable passing through the frame, the mode switching controller is electrically connected to the linear regulator, and the mode switching controller is electrically connected to a touch interface, and the touch interface is provided with two non-adjacent touch pads; the liquid crystal lens is electrically connected to the MCU, and the MCU controls the brightness and flickering frequency of the liquid crystal lens; When the temple is opened, the power switch controller senses the magnetic field generated by the magnet, the power switch controller is turned on, the power of the micro battery is input to the linear regulator, and after voltage stabilization, the stable output voltage is sent to the MCU and the mode switching controller, providing a stable power supply voltage for the two devices; The control method of the liquid crystal glasses with the functions of relieving eye fatigue and visual training comprises the following steps: The initial state of the liquid crystal glasses after power-on is set to an eye protection mode, and the control method of the eye protection mode includes: touching the two touch pads from back to front successively, the blackness of the liquid crystal lens increases; touching the two touch pads from front to back successively, the blackness of the liquid crystal lens decreases; When at least one of the touch pads is touched for a set time, the eye protection mode is switched to the training mode. In the training mode, the liquid crystal lens alternately turns black, becomes transparent and flickers under the control of the MCU, specifically including: touching two of the touch pads from back to front, the blackness of the liquid crystal lens remains unchanged, and the flickering frequency of the liquid crystal lens increases; touching two of the touch pads from front to back, the blackness of the liquid crystal lens remains unchanged, and the flickering frequency of the liquid crystal lens decreases; Touching the two touch pads successively from back to front, so that the blackness of the liquid crystal lens increases, specifically includes: The two touch pads generate capacitance to the mode switching controller successively. The pins P13 and P12 of the mode switching controller successively output low-level signals to the MCU. The MCU determines that it is sliding forward according to the low-level signals detected successively from the two pads. When the MCU receives the signal of sliding forward, the PWM16 function of the MCU is enabled and the output waveforms of the CLK and DAT pins are adjusted, so that the time of the waveform Ton obtained on the liquid crystal lens increases and the time of Toff decreases, wherein the total time of Ton+Toff remains unchanged, 1000 / (Ton+Toff)=24~250. Under the condition that the total time of Ton+Toff remains unchanged, that is, the flickering frequency remains unchanged, after the time of Ton increases and the time of Toff decreases, the total time that the liquid crystal lens is lit per unit time increases, thereby achieving the effect of increasing the blackness of the lens; Touching the two touch pads successively from front to back, so that the blackness of the liquid crystal lens decreases, specifically includes: The two touch pads generate capacitance to the mode switching controller successively. The pins P12 and P13 of the mode switching controller successively output low-level signals to the MCU. The MCU determines that it is sliding backward according to the successively low-level signals of the two pads. When the MCU receives the signal of sliding forward, the PWM16 function of the MCU is enabled and the output waveforms of the CLK and DAT pins are adjusted, so that the time of the waveform Toff obtained on the liquid crystal lens increases and the time of Ton decreases, wherein the total time of Ton+Toff remains unchanged, 1000 / (Ton+Toff)=24~250. Under the condition that the total time of Ton+Toff remains unchanged (the flickering frequency remains unchanged), the time of Toff increases and the time of Ton decreases, and the total time of the liquid crystal lens being closed per unit time increases, thereby achieving the effect of reducing the blackness of the lens; The units of Ton and Toff are ms; Ton is the high level time added to the liquid crystal lens, when the high level is on, the liquid crystal lens is lit; Toff is the low level time added to the liquid crystal lens, when the low level is on, the liquid crystal lens is turned off; Ton+Toff is a conversion cycle, the total number of cycles converted within 1 second is the flashing frequency, and the flashing frequency is controlled at 24HZ~250HZ, that is: 1000 / (Ton+Toff)=24~250; Touching the two touch pads successively from back to front, the blackness of the liquid crystal lens remains unchanged and the flickering frequency of the liquid crystal lens increases, specifically includes: The two touch pads generate capacitance to the mode switching controller successively. The pins P13 and P12 of the mode switching controller successively output low-level signals to the MCU. The MCU determines that it is sliding forward according to the low-level signals detected successively from the two pads. When the MCU receives the signal of sliding forward, it enables the PWM16 function of the MCU and adjusts the output waveforms of the CLK and DAT pins, so that the time of Ton+Toff in the waveform T-frame obtained on the liquid crystal lens is reduced, and Ton and Toff are reduced by the same unit, so as to achieve the effect of unchanged lens blackness and increased lens flickering frequency, flickering frequency = 1000 / T-frame; Touching the two touch pads successively from front to back, the blackness of the liquid crystal lens remains unchanged and the flickering frequency of the liquid crystal lens decreases, specifically includes: The two touch pads generate capacitance to the mode switching controller successively. The pins P12 and P13 of the mode switching controller successively output low-level signals to the MCU. The MCU determines that it is sliding backward according to the low-level signals detected successively from the two pads. When the MCU receives the signal of sliding forward, it enables the PWM16 function of the MCU and adjusts the output waveforms of the CLK and DAT pins, so that the time of Ton+Toff in the waveform T-frame obtained on the liquid crystal lens increases, and Ton and Toff increase by the same unit, so as to achieve the effect of unchanged lens blackness and reduced lens flicker frequency, flicker frequency = 1000 / T-frame; Method to adjust the blackening and transparent dwell time: In the training mode, when the finger touches the right temple in a short touch mode without sliding backward or forward, the two pads in the touch interface of the mode switching controller generate sensing capacitance at the same time or generate sensing capacitance individually and then output it to the mode switching controller, and the pin of the mode switching controller outputs a corresponding low-level signal to the MCU, and the MCU determines it as a short touch based on the received signal; then the MCU enables the PWM16 function and adjusts the output waveforms of the CLK and DAT pins, so that the time distribution ratio of the waveform Ton and Toff obtained on the liquid crystal lens is adjusted accordingly, and each time the touch is performed, Ton increases and Toff decreases, and T is cycled to the minimum value again after Ton increases to the maximum, and the cycle is repeated in sequence; under the condition that the sum of Ton+Toff remains unchanged, by adjusting the time distribution ratio of Ton and Toff, the residence time of the lens turning black or transparent can be adjusted under the condition that the flickering frequency of the lens remains unchanged; When used as a training glasses reaction speed for athletes, In the first stage, the flashing frequency of the lens is adjusted to 5HZ, and the residence time of the lens turning black and transparent is 1:2; In the second stage, the flashing frequency of the lens remains unchanged at 5HZ, and the dwell time between blackening and becoming transparent is adjusted to 1:1, increasing the blackening time so that the human eye cannot see the external scenery for a longer time, thereby achieving the goal of training athletes to catch and throw the ball; In the third stage, the flashing frequency of the lens remains unchanged at 5HZ, and the dwell time between blackening and becoming transparent is adjusted to 2:1, further increasing the blackening time, so that the time that the human eye cannot see the external scenery is further increased, thereby further training the athlete's sense of catching and throwing the ball; In the fourth stage, the flickering frequency of the lens is adjusted from 5HZ to 10HZ, which increases the flickering frequency of external scenes seen by the human eye and further trains the reaction speed of the eyes.
