Description

Technical Field

[0001] The invention belongs to the field of glasses, and in particular relates to ophthalmic examination glasses based on electrochromic materials. Background Art

[0002] In existing eye exams, vision tests are performed on one eye, typically using an eye chart. The examinee stands a certain distance from the chart and then covers the other eye with their hand or a hand-held mask. When covering one eye with their hand, the examinee may look through the gap in their hand and use the eye chart, resulting in inaccurate test results. Holding the mask over one eye for too long can cause hand fatigue, especially during pediatric exams, where children are reluctant to hold the mask and may cry due to fatigue. Summary of the Invention

[0003] The purpose of the present invention is to provide an ophthalmic examination spectacles based on electrochromic materials in order to solve the above problems existing in the prior art.

[0004] The objectives of the present invention can be achieved through the following technical solutions: A pair of ophthalmic examination glasses based on electrochromic materials, characterized in that it includes a frame and a first electrochromic device and a second electrochromic device installed on the frame, the first electrochromic device is provided with a first control device, the second electrochromic device is provided with a second control device, a first button is provided on one side of the frame, and a second button is provided on the other side of the frame, the first button is used for a person to press so that the first control device controls the first electrochromic device to be in a shielded state or to release the shielding, and the second button is used for a person to press so that the second control device controls the second electrochromic device to be in a shielded state or to release the shielding; the first control device and the second control device are both provided with regulators, and the two regulators are electrically connected to the first electrochromic device and the second electrochromic device respectively.

[0005] The working principle of the present invention is as follows: the examinee wears the glasses frame, and the first electrochromic device and the second electrochromic device are respectively located in front of the examinee's left and right eyes. Taking the case where the first electrochromic device is located in front of the left eye and the second electrochromic device is located in front of the right eye as an example, when performing a vision test on the left eye, it is necessary to cover the right eye (in the initial state, the first electrochromic device and the second electrochromic device are both in an unshielded state), press the second button, the second control device controls the second electrochromic device to be in a shielded state, and the second electrochromic device shields the right eye. After the vision test of the left eye is completed, the vision test of the right eye is performed, and the second button is pressed again, the second control device controls the second electrochromic device to be unshielded (i.e., in an unshielded state), press the first button, the first control device controls the first electrochromic device to be in a shielded state, and the first electrochromic device shields the left eye. When the first electrochromic device needs to be unshielded, press the first button again. By pressing the first button, the shielding state and the unshielded state of the first electrochromic device are switched, and by pressing the second button, the shielding state and the unshielded state of the second electrochromic device are switched. The unshielding of the electrochromic device is used to indicate that the electrochromic device is in a colorless and transparent state at this time (i.e., it cannot play a shielding role). The electrochromic devices are all in a shielded state to indicate that the electrochromic device is in a colored state at this time (i.e., it can play a shielding role on the line of sight). The first control device and the second control device control the first electrochromic device and the second electrochromic device to be in a shielded state or to unshield by controlling the output voltage of the corresponding regulator. Wearing the present invention, the left eye or right eye of the wearer is shielded by pressing the first button or the second button, which facilitates the vision test.

[0012] In the above-mentioned ophthalmic examination glasses based on electrochromic materials, a limit block is set on the outer side of the first air tube, and a limit groove is opened on the inner wall of the second air tube. The limit groove is set along the length direction of the second air tube. The movement of the movable frame drives the movement of the first air tube so that the limit block moves along the length direction of the limit groove. The limit groove is used to cooperate with the limit block to limit the moving distance of the first air tube.

[0013] In the above-mentioned ophthalmic examination glasses based on electrochromic materials, a first channel and a second channel are further provided in the frame, one end of the first channel is connected to the two return flow channels, the other end of the first channel is provided with a first opening, the frame is provided with an air port, one end of the second channel is connected to the air port, the other end of the second channel is provided with a second opening, and swing-type one-way valves are provided at the first opening and the second opening.

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1-12As shown, a pair of ophthalmic examination glasses based on electrochromic materials includes a frame 1 and a first electrochromic device 2 and a second electrochromic device 3 mounted on the frame 1, the first electrochromic device 2 is provided with a first control device 4, the second electrochromic device 3 is provided with a second control device 5, a first button 6 is provided on one side of the frame 1, and a second button 36 is provided on the other side of the frame 1, the first button 6 is used for a person to press so that the first control device 4 controls the first electrochromic device 2 to be in a shielded state or to release the shielding, and the second button 36 is used for a person to press so that the second control device 5 controls the second electrochromic device 3 to be in a shielded state or to release the shielding.

[0031] like Figure 3-4 As shown, the first electrochromic device 2 and the second electrochromic device 3 are both provided with a first transparent substrate layer 28, a first transparent conductive layer 29, an electrochromic layer 30, an ion conductive layer 31, an ion storage layer 32, a second transparent conductive layer 33, and a second transparent substrate layer 34.

[0032] The first transparent substrate layer 28 and the second transparent substrate layer 34 are both made of transparent materials such as glass, and the electrochromic layer 30 is made of electrochromic material.

[0033] The first control device 4 and the second control device 5 are both provided with a regulator 35, which has a built-in power supply. One path of the regulator 35 is electrically connected to the first transparent conductive layer 29, and another path of the regulator 35 is electrically connected to the second transparent conductive layer 33. The first control device 4 and the second control device 5 control the output voltage of the corresponding regulator 35 to control the first electrochromic device 2 and the second electrochromic device 3 to be in a shielded state or to release the shielding.

[0034] In further detail, a light shield 7 is provided around the first electrochromic device 2 and the second electrochromic device 3. The light shield 7 shields the area around the eyes, thereby improving the shielding effect.

[0035] In further detail, both light shields 7 include multiple air bags 8, and the air bags 8 are connected to the first air pipes 9. There are multiple first air pipes 9, and the first air pipes 9 are connected to the air bags 8 and correspond one to one.

[0036] In further detail, the frame 1 is provided with a movable frame 10, the airbag 8 is provided on one side of the movable frame 10, and the first air tube 9 is provided on the other side of the movable frame 10. A person can move the movable frame 10 to move it, and the movement of the movable frame 10 drives the airbag 8 and the first air tube 9 to move together.

[0037] In further detail, the frame 1 includes temples 11 and a frame 12. The frame 12 is provided with two circular flow channels 13. The circular flow channels 13 are provided with multiple second air tubes 14. The second air tubes 14 are sleeved around the first air tube 9. The first air tube 9 has a first air hole 15, and the second air tube 14 has a second air hole 16. The second air hole 16 is connected to the circular flow channel 13. The movable frame 10 can move relative to the frame 12 so that the first air hole 15 and the second air hole 16 are connected or dislocated. The first air tube 9 and the second air tube 14 correspond one-to-one.

[0038] A person moves the movable frame 10 away from the lens frame 12. The movement of the movable frame 10 drives the first air tube 9 to move along the length direction of the second air tube 14 until the first air hole 15 and the second air hole 16 are connected. Then the movement of the movable frame 10 is stopped. When the first air hole 15 and the second air hole 16 are connected, since the second air hole 16 is connected to the return channel 13, the air bag 8 is connected to the return channel 13 through the first air tube 9. By operating the movable frame 10 or the lens frame 12, the movable frame 10 moves relative to the lens frame 12 and approaches the lens frame 12. The movable frame 10 drives the first air tube 9 to move along the length direction of the second air tube 14. When the movable frame 10 and the lens frame 12 are attached together, the first air hole 15 and the second air hole 16 are misaligned, and the first air hole 15 and the second air hole 16 are not connected. Therefore, the air bag 8 is not connected to the return channel 13. This setting can achieve the connection and disconnection of the air bag 8 and the return channel 13.

[0039] To be more specific, a first channel 20 and a second channel 21 are further provided in the mirror frame 12. One end of the first channel 20 is connected to the two return flow channels 13, and the other end of the first channel 20 is provided with a first opening 22. The mirror frame 12 is provided with an air port 24. One end of the second channel 21 is connected to the air port 24, and the other end of the second channel 21 is provided with a second opening 23. Swing check valves 25 are provided at the first opening 22 and the second opening 23. The swing-type one-way valve 25 includes a spring 26 and a valve plate 27 for sealing the first opening 22 and the second opening 23. One end of the valve plate 27 is rotatably connected to the mirror frame 12, and the valve plate 27 is tilted to cover the first opening 22 and the second opening 23. One end of the spring 26 is connected to the valve plate 27, and the other end of the spring 26 is fixedly connected to the mirror frame 12. When the airbag 8 is deflated, the gas flows out from the first channel 20, pushes open the valve plate 27, and then flows to the second channel 21. When the airbag 8 is inflated, the gas flows into the second channel 21, pushes open the valve plate 27, and then flows to the first channel 20.

[0040] When inflating the airbag 8, first move the movable frame 10 away from the lens frame 12, and the first air tube 9 moves along the length direction of the second air tube 14 until the first air hole 15 and the second air hole 16 are connected, so that the airbag 8 and the return flow channel 13 are connected.

[0041] The nozzle of the air pump is then inserted into the air port 24 to inflate the airbag 8. Gas enters through the air port 24, flows along the second channel 21 to the second opening 23, and pushes open the valve plate 27, which is tilted to cover the first and second openings 22 and 23. The valve plate 27 rotates and compresses the spring 26. After the valve plate 27 is pushed open, the gas flowing out of the second opening 23 flows through the first opening 22 into the first channel 20, then into the two return flow channels 13, and then through the second air hole 16 and the first air hole 15 into the first air pipe 9, and finally into the airbag 8, causing the airbag 8 to be fully inflated.

[0042] After inflation is completed, the air nozzle of the air pump is pulled out. Under the restoring force of the spring 26, the spring 26 pushes the valve plate 27 to rotate, and the valve plate 27 is tilted again to cover the first opening 22 and the second opening 23, and the valve plate 27 seals the first opening 22 and the second opening 23.

[0043] Then the tester wears the therapeutic glasses and presses the movable frame 10 toward one side of the tester's eye, so that the airbag 8 is pressed around the eye. During the pressing process, the gas in the airbag 8 is pressed out of the airbag 8. Due to the different shapes around the eye, the amount of gas pressed out of different airbags 8 is different. After the gas in the airbag 8 is pressed out of the airbag 8, it flows to the return channel 13 through the first air hole 15 and the second air hole 16, and then flows along the first channel 20 to the first opening 22. The gas pushes open the valve plate 27 which is tilted to cover the first opening 22 and the second opening 23. The valve plate 27 rotates the compression spring 26. After the valve plate 27 is pushed open, the gas flowing out of the first opening 22 flows into the second channel 21 from the second opening 23, and finally flows out to the outside atmosphere from the air port 24.

[0044] The spring 26 is used to press against the valve plate 27 so that the valve plate 27 cannot rotate without the push of the gas flowing out of the first opening 22 or the second opening 23 .

[0045] After pressing airbags 8 around the eyes, the frame 12 is pressed toward the movable frame 10, so that the movable frame 10 and the frame 12 are attached together. The first air holes 15 and the second air holes 16 are misaligned and disconnected, preventing the gas in the airbags 8 from flowing out into the circular flow channel 13. Through this operation, the amount of gas in different airbags 8 varies, resulting in different inflated sizes of the airbags 8. This allows the lens hood 7 to conform to the shape of the tester's eyes, achieving a better shielding effect.

[0046] For different testers, it is only necessary to repeat the above operation, move the movable frame 10 away from the frame 12, and then inflate the airbag 8. After the inflation is completed, press the movable frame 10 toward the side of the tester's eye. After the pressing is completed, press the frame 12 again so that the movable frame 10 and the frame 12 fit together.

[0047] To be more specific, a limiting block 17 is provided on the outside of the first air pipe 9, and a limiting groove 18 is provided on the inner wall of the second air pipe 14. The limiting groove 18 is provided along the length direction of the second air pipe 14. The movement of the movable frame 10 drives the first air pipe 9 to move, so that the limiting block 17 moves along the length direction of the limiting groove 18. The limiting groove 18 is used to cooperate with the limiting block 17 to limit the moving distance of the first air pipe 9.

[0048] When the first air tube 9 moves along the length of the second air tube 14, the stopper 17 moves along the length of the stopper slot 18. When the first air hole 15 and the second air hole 16 are aligned, the stopper 17 moves to the end of the stopper slot 18. When the stopper 17 moves to the end of the stopper slot 18 and is blocked by the side wall of the stopper slot 18, the first air hole 15 and the second air hole 16 are aligned. This arrangement limits the movement distance of the first air tube 9 so that the first air hole 15 and the second air hole 16 can be aligned.

[0049] In further detail, grooves 19 are provided on the upper and lower sides of the movable frame 10. The grooves 19 are used for inserting a finger into the movable frame 10. The fingertips of the person insert into the grooves 19, and then the movable frame 10 is moved away from the frame 12. The provision of the grooves 19 facilitates the person to move the movable frame 10 away from the frame 12.
