[0002] Myopia prevention glasses are designed for students. Currently, data shows that over 70% of high school and university students in my country are nearsighted, with many children starting to wear glasses from elementary or middle school. Among office workers, many face the problem of prolonged computer use, late nights, heavy workloads, and persistent eye strain. Excessive screen time, close-range viewing, and excessively bright or dim lighting are the main causes of myopia.

[0021] Example: This invention discloses a myopia control glasses, including a frame 1, a fogging lens 2 disposed within the frame 1, and a control circuit module 30 electrically connected to the fogging lens 2. The control circuit module 30 is a PCB circuit board, which is built into the outer shell of the frame 1 or placed near the bridge of the nose.

[0022] Combination Figure 1 and Figure 4 As shown, the control circuit module 30 includes a USB charging circuit 31, a battery power supply and detection circuit 32, a glasses opening and closing detection module 33, a microcontroller module 34, and an atomization drive circuit 35.

[0023] The USB charging circuit 31 connects to the battery power supply and detection circuit 32 to provide charging functionality. The battery power supply and detection circuit 32 also provides power to other hardware circuit modules. The glasses opening / closing detection module 33 detects changes in the temple opening / closing state and feeds back a first electrical signal to the microcontroller module 34. The fogging drive circuit 35 controls the fogging degree of the fogging lens 2 based on the control signal from the microcontroller module 34. The glasses opening / closing detection module 33 can use a limit switch. The limit switch can be installed at the hinge position between the temple and the frame 1 to sense whether the temple is open. The above structure is already implemented in existing technology and is only briefly described here; it is not considered the core technology of this solution.

[0024] This solution is based on the aforementioned hardware and has been improved by adding a sub-frame 5, combined with... Figure 1 , Figure 2 and Figure 3 The inner side of the frame 1 is fitted with a sub-frame 5 via a snap-fit ​​structure 6. The sub-frame 5 holds a prescription lens. The snap-fit ​​structure 6 includes a slot 61 and a latch 62. The slot 61 is located at the nose pad position of the frame 1, and the latch 62 is located at the bridge of the sub-frame. The fogging lens 2 is a plano lens.

[0025] according to Figure 4 As shown, a distance measuring module 36 can be installed on the outer bridge of the nose or at both ends of the eyeglass frame 1. The distance measuring module 36 senses the distance to obstructions directly in front of the eyeglass frame 1 and outputs a sensing signal to the microcontroller module 34. The distance range sensed by the distance measuring module 36 is set to 30cm. When the distance is greater than or equal to 30cm, the fogging function is turned off; when the distance is less than 30cm, the fogging function is turned on. The aforementioned distance measuring module 36 is an existing laser distance measuring hardware module, readily available and purchasable on the market. In this solution, its function is utilized, and it is installed in the middle or at both ends of the eyeglass frame 1 for distance measurement. This determines whether the eyeglass frame 1 is too close to objects. By measuring the distance, the fogging function is controlled, thereby alerting the user and promoting good eye habits.

The power regulation circuit 351 receives power from the battery and simultaneously provides power to the first drive circuit 352 and the second drive circuit 353. The first drive circuit 352 and the second drive circuit 353 have the same structure. The first drive circuit 352 is connected to pin P13 and provides a P2 terminal, which is used to connect one atomizing lens 2. The second drive circuit 353 is connected to pin P14 and provides a P4 terminal, which is used to connect another atomizing lens 2.

[0028] The power regulation circuit 351 includes a chip U2, an inductor L1, a diode D1, resistors R10, R15, and R4, and capacitors C15 and C14. The first pin of chip U2 is connected to one end of inductor L1 and the anode of diode D1. The second pin of chip U2, one end of capacitor C15, one end of resistor R15, and one end of capacitor C14 are all grounded. The third pin of chip U2 is connected to the other end of resistor R15 and one end of resistor R10. The fourth pin of chip U2 is connected to the twentieth pin of the microcontroller through resistor R4. The fifth pin of chip U2 is connected to the battery power supply terminal. The other end of capacitor C15 is connected to the other end of inductor L1. The cathode of diode D1 is connected to the other end of resistor R10 and the other end of capacitor C14, providing power to the first drive circuit 352 and the second drive circuit 353.

[0029] In the above circuit, the microcontroller's P13 and P14 pins output PWM1 and PWM2 signals, respectively, which drive the atomizing lens 2 through the first driving circuit 352 and the second driving circuit 353. The first driving circuit 352 includes switching transistors Q6, Q5, and Q3. The PWM1 signal is provided to the gate of switching transistor Q6 through resistor R21. The source of switching transistor Q6 is grounded, and its drain is connected to the intermediate signal S1 and, through resistor R13, to the gate of switching transistor Q5. The drain of switching transistor Q5 is grounded, and its source is connected to the drain of switching transistor Q3 and provides terminal P2, which is used to connect to the atomizing lens 2. The gate and source of switching transistor Q3 are connected to the output of the power supply regulation circuit 351, and the gate of switching transistor Q3 is connected to the intermediate signal S2 of the second driving circuit 353 through resistor R14. Switching transistor Q6 is an N-type MOSFET, while switching transistors Q3 and Q5 are P-type MOSFETs.

[0030] The second driving circuit 353 includes switching transistors Q7, Q2, and Q1. Signal PWM2 is provided to the gate of switching transistor Q7 through resistor R17. The source of switching transistor Q7 is grounded, and its drain is connected to the intermediate signal S2 and, through resistor R24, to the gate of switching transistor Q1. The drain of switching transistor Q1 is grounded, and its source is connected to the drain of switching transistor Q2 and provides terminal P4, which is used to connect to the atomizing lens 2. The gate and source of switching transistor Q2 are connected to the output of the power regulation circuit 351, and the gate of switching transistor Q2 is connected to the intermediate signal S1 of the second driving circuit 353 through resistor R9. Switching transistor Q7 is an N-type MOSFET, and switching transistors Q1 and Q2 are P-type MOSFETs.

[0031] Functional effect analysis of this scheme: The first drive circuit 352 and the second drive circuit 353 adopt a bridge topology circuit structure, which is suitable for PWM wave control and driving. The power supply for the first drive circuit 352 and the second drive circuit 353 is provided by the power conditioning circuit 351. The BAT+ terminal of the power conditioning circuit 351 is connected to the battery. When the P20 pin of the microcontroller module 34 provides a signal, the chip U2 starts to work. At the same time, the battery power passes through the inductor L1, allowing the DC current to flow smoothly. The diode D1 keeps the current flowing out in one direction. Through the voltage divider feedback of resistors R10 and R15, the voltage on the current output side is detected by voltage division. The third pin of the chip U2 is the feedback pin. Therefore, according to the voltage feedback, the output of the first pin is adjusted at any time, so that the output of the power conditioning circuit 351 can be more stable, and the DC current can be provided to the first drive circuit 352 and the second drive circuit 353. Compared with traditional drives, the first drive circuit 352 and the second drive circuit 353 can avoid the interference of PWM wave signals due to the power supply of the power conditioning circuit 351. This circuit, on the one hand, can modulate the power supply into a reliable DC current, overcoming the influence of PWM waves. On the other hand, it uses PWM1 and PWM2 to drive the signal separately, thereby avoiding signal resonance.

[0032] This invention enhances the intelligence of the glasses through a control circuit module 30. A battery-powered and detection circuit provides power to ensure the normal operation of other hardware. The microcontroller module 34 detects the opening and closing of the temples to identify whether someone is wearing the glasses. The fogging drive circuit 35 controls the fogging lens 2 to provide fogging alerts. Furthermore, the sub-frame 5 can be installed according to different user preferences. After being attached to the frame 1 using a snap-fit ​​structure 6, it can be worn by nearsighted users, while non-nearsighted users can remove the sub-frame for easier operation. The distance sensing module 36 is set to a distance range of 30cm. When the distance is greater than or equal to 30cm, the fogging function is turned off; when the distance is less than 30cm, the fogging function is turned on. This reminds users to maintain good viewing distance and eye habits.
