[0003] The existing glasses on the market have single functions and can only help users correct their vision, but cannot relieve visual fatigue, correct users' sitting posture, or change users' eye habits. If users want to relieve visual fatigue, they can only rely on auxiliary tools that can relieve eye fatigue, such as steam eye masks, eye massagers, etc. Steam eye masks mainly use the slight heat of steam to promote blood circulation in the eyes, relieve tense eye muscles, and eliminate eye fatigue and discomfort, while eye massagers stimulate and exercise vertebral cells and optic nerves through point-to-point massage of important acupoints around the eyes, so as to relieve eye fatigue and restore the elasticity of the ciliary muscles.

[0040] Reference Figures 1 to 11 The working principle of the multifunctional protective glasses of the present invention is:

[0041] When the user clamps the host 4 on the pile head on the left side of the frame 1, the four female sockets 72 are electrically connected to the four probes 46 through their respective contacts 721, and the host PCB board 43 controls the power supply battery 44 to supply power to the heating wire 7. The heating wire 7 generates heat and transfers the heat to the front frame 11 and the rear frame 12. At the same time, the host PCB board 43 controls the frequency generator to release a specific frequency to act on the eye part, resonate with the natural frequency of the eye, and maintain vision. At this time, the glasses collect information such as the user's sitting posture, the distance between the glasses and the desktop, and the intensity of the ambient light through the gyroscope, light sensor and ranging sensor.

[0042] When the user's sitting posture is incorrect and the distance between the glasses and the table is abnormal, the host PCB board 43 controls the vibrator to vibrate and the speaker to sound an alarm. At the same time, the host PCB board 43 sequentially supplies power to the two lenses 5 through the connecting wire 81, the two conductive parts 8, and the four contact probes 84. The two lenses 5 heat up and change color. At this time, the user cannot see the objects in front of the eyes through the two lenses 5, and the user is reminded to correct the bad sitting posture and eye habits in time.

[0043] When the battery life of the host 4 is insufficient, the user can clip the control box 3 on the clothes, insert the USB plug 22 at one end of the USB cable 2 into the USB interface 331 of the control box 3, and connect the magnetic head 21 at the other end of the USB cable 2 to the magnetic seat 431 of the host 4 in a magnetic way, and snap the middle part of the USB cable 2 onto the wire buckle 61 of the left temple 6, so that the control box 3 can be electrically connected to the host 4, and power can be supplied to the heating wire 7 and the two lenses 5;

[0044] When the power of the external battery 34 in the control box 3 is insufficient, the control box 3 can be removed for charging.

[0045] The multifunctional protective glasses of the present invention control the heating wire 7 to generate heat through the host 4, heat the frame 1, generate heat in various parts of the frame 1, heat the eye area in all directions, promote eye blood circulation, and eliminate eye fatigue. At the same time, the user's sitting posture is collected by using a gyroscope and a distance measuring sensor. The host 4 controls the two lenses 5 to be powered on and heated, so that the lenses 5 change color, and the user's bad sitting posture and eye habits are corrected in time, thereby improving the eye habits and facilitating the user to use the glasses in various time periods and occasions.

[0046] The multifunctional protective glasses of the present invention are mainly aimed at specific personnel (such as students). They are compatible with ordinary similar frames. Biocomposite materials can be added to the frames to release information of functional materials, realize far-infrared physiotherapy functions, promote blood circulation, reduce visual fatigue and other functions, and are used to correct sitting posture and change eye habits. The frame 1 is provided with a functional module, and the heating wire 7 and the lens 5 are externally connected to the host 4. The frame 1 is provided with a contact 721. The host 4 is used to supply power to the heating wire 7 and the lens 5 to control the heating of the heating wire 7 and the lens 5. The control box 3 can also be externally connected to supply power to the heating wire 7 and the lens 5 to increase the endurance. The glasses are more suitable for people who wear them for a long time and are comfortable to wear.

[0047] The multifunctional protective glasses of the present invention collect information such as the user's sitting posture, the distance between the glasses and the desktop, and the intensity of the ambient light at this time through the settings of a gyroscope, a light sensor and a distance measuring sensor, and use a vibrator to vibrate and a speaker to sound an alarm to promptly correct the user's bad sitting posture and eye habits, thereby improving eye habits and reducing the probability of eye diseases such as astigmatism.

[0048] The multifunctional protective glasses of the present invention use digital intelligent control adjustable electric constant temperature far-infrared hot moxibustion eye-brightening technology. Acupoint moxibustion refers to irradiating specific far-infrared acupoints of the eye and performing electric constant temperature moxibustion on the acupoints. Physiologically stimulate the nerve receptors and peripheral blood microcirculation system around the eye, improve the blood circulation around the eye, regulate blood oxygen and nutrient metabolism and activate the ciliary muscle regulation function, relax the spasm and fatigue state of the extraocular rectus muscle and relieve the compression of the extraocular rectus muscle on the sclera. At the same time, the far infrared rays released by the digital intelligent control adjustable electric constant temperature far-infrared hot moxibustion eye-brightening instrument promote the secretion of dopamine in the eye to inhibit the growth of the eye axis, relax the ciliary muscle to regulate tension and spasm and regulate the ciliary muscle blood circulation system, improve the stress regulation ability and regulation range of the ciliary muscle, thereby reducing the false high myopia degree caused by the height of the ciliary muscle and the tension and spasm of the regulated spastic myopia and mixed myopia, and improving naked eye vision and corrected vision.

[0049] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
