[0039] When performing some vision screening tests, the vision screening device needs to observe and capture the entire human iris in order to make the test results more accurate. However, due to the differences and diversity of the human eye, the iris of many people's eyes will be partially blocked by the lower eyelid, causing deviations in the test results or even making the test impossible to complete. There are currently two main types of vision screening devices on the market. One is a portable handheld vision screening device (the user holds the device 1 meter away from the person being tested), and the other is a desktop vision screening device that requires the person being tested to place their forehead on the predetermined position of the device. The above problems exist in both types of tests.

[0040] In order to solve the above problems, the present invention proposes an auxiliary structure, an auxiliary panel and a vision screening instrument for opening the lower eyelid, aiming to provide an auxiliary structure, an auxiliary panel and a vision screening instrument for opening the lower eyelid that are conducive to improving the inspection results. Figures 1 to 3 A schematic structural diagram of an embodiment of the auxiliary structure for opening the lower eyelid provided by the present invention.

[0041] Please refer to Figure 1 In one embodiment of the present invention, the auxiliary structure 100 for opening the lower eyelid includes a seat body 101 and a contact 102; the seat body 101 is arranged relative to the lower eyelid of the human body, and has an eye contact position; the contact 102 is protruding from the end surface of the seat body 101 relative to the lower eyelid of the human body, and is arranged on one side relative to the eye contact position, so that when the seat body 101 moves toward the direction of the lower eyelid of the human body, the contact 102 squeezes the lower eyelid of the human body.

[0042] The technical solution of the present invention adopts the contact 102 which is protruding from the end surface of the base body 101 relative to the lower eyelid of the human body and is arranged on one side relative to the eye contact position. When the base body 101 moves toward the direction of the lower eyelid of the human body, the contact 102 squeezes the lower eyelid of the human body, thereby causing the lower eyelid of the human body to move toward the lower eye socket, thereby avoiding the lower eyelid of the human body covering the iris area, thereby making the examination result of the patient more accurate, thereby improving the accuracy and efficiency of the examination result.

[0043] For further information, please refer to Figure 1 , the contact 102 is tilted in the direction away from the eye contact position. It can be understood that, in some embodiments, the contact 102 is vertically protruded from the base body 101, so when the base body 101 moves toward the lower eyelid of the human body, the contact 102 squeezes the lower eyelid of the human body, and the amount of movement of the lower eyelid of the human body toward the lower eye socket is insufficient, but the lower eyelid is squeezed into the eye socket, which is very likely to cause discomfort to the patient. Therefore, in other embodiments, the contact 102 is tilted in the direction away from the eye contact position, thereby converting the amount of squeezing the lower eyelid by the contact 102 into the amount of movement of the lower eyelid downward. With this arrangement, on the basis of avoiding the lower eyelid blocking the iris area, more attention is paid to the patient's detection experience, thereby ensuring the accuracy and efficiency of the detection on the one hand, and providing comfortable services for the patient at the same time.

[0044] For further information, please refer to Figure 1 , the angle between the contact 102 and the horizontal plane is a, wherein 5°<a<45°. It is understandable that, in some embodiments, the vertical protrusion between the contact 102 and the seat body 101 causes discomfort to the patient during the test. In order to further improve the comfort of the patient during the test, the contact 102 is tilted in the direction away from the eye contact position. This arrangement not only avoids the lower eyelid from blocking the iris area, but also pays more attention to the patient's test experience, thereby ensuring the accuracy and efficiency of the test, and providing comfortable services for the patient. As for the required tilt angle, through a large number of embodiments, the angle between the contact 102 and the horizontal plane is a, among which 5°<a<45° is most appropriate. If the angle is too small, it will still make the patient's glasses uncomfortable. If the angle is too large, it will be difficult to move the lower eyelid toward the lower eye socket, and the lower eyelid will easily block the iris area, causing inaccurate detection. Therefore, it is most appropriate to control the tilt angle to 5°-45°. Among them, in the most preferred embodiment, the angle between the contact 102 and the horizontal plane is 15°.

[0045] In addition, please refer to Figure 1, the contact 102 is convexly provided with 2mm-20mm. It can be understood that not only the angle of the contact 102 is the key to move the lower eyelid to the lower eye socket, but also the protruding length of the contact 102 is an important factor. In some embodiments, the contact 102 is protruded too long, which may cause excessive squeezing of the patient's eyeball and affect the comfort. In other embodiments, the protruding length of the contact 102 is too short, which may have a poor effect on the movement of the patient's lower eyelid, or may cause the lower eyelid to block the iris area and cause inaccurate detection. Therefore, after a large amount of data verification, the contact 102 is convexly provided with 2mm-20mm as the most suitable length, wherein the most preferred embodiment is a convex length of 10mm.

[0046] In addition, the material of the contact 102 includes soft silicone. It is understandable that in order to open the patient's lower eyelid to obtain accurate detection data, the material of the contact 102 includes but is not limited to metal, hard plastic, etc., but in order to further improve the patient's experience and comfort during detection, the most preferred embodiment of the material of the contact 102 includes soft silicone. In this way, the impact and collision between the contact 102 and the patient's lower eyelid are reduced and absorbed by the soft silicone, and the soft silicone is more close to the skin, which further makes the patient feel comfortable.

[0047] The present invention also provides an auxiliary panel 200 for opening the lower eyelid, please refer to Figure 2 The auxiliary panel 200 for opening the lower eyelid includes a panel body 201 and the auxiliary structure 100 for opening the lower eyelid.

[0048] Among them, please refer to Figure 2 The plate body 201 is arranged in a ring shape and has an eye-contacting end surface corresponding to the human eye. Specifically, the auxiliary structure 100 for opening the lower eyelid is connected to the eye-contacting end surface. The plate body 201 and the seat body 101 can also be arranged in one piece.

[0049] For further information, please refer to Figure 2, the eye contact end surface is provided with two corresponding to the human eye, and the auxiliary structure 100 for opening the lower eyelid is provided with two, which are installed at the eye contact position in a one-to-one correspondence at intervals. It can be understood that in order to avoid the need to change the eye to test the other eye after testing one eye, the eye contact end surface is provided with two corresponding to the human eye, and the auxiliary structure 100 for opening the lower eyelid is provided with two, which are installed at the eye contact position in a one-to-one correspondence at intervals. With such a configuration, two eyes can be tested at one time without the patient having to take any action, which is more convenient.

[0050] For further information, please refer to Figure 2 , an avoidance groove 202 is concavely provided between the two eye-engaging end surfaces. It can be understood that, since the nose of the human face is between the two eyes and is protruding relative to the two eyes, in order to further provide the patient with a good detection experience and to prevent the auxiliary panel 200 for opening the lower eyelid from pressing the patient's nose during the detection process, the avoidance groove 202 is concavely provided between the two eye-engaging end surfaces, and the avoidance groove 202 is used to avoid or accommodate the bridge of the nose, so that the patient does not feel uncomfortable due to the pressure on the bridge of the nose during the detection process, and the comfort is further improved.

[0051] In addition, please refer to Figure 3 , a connection structure 203 is provided at the position of the plate body 201 facing away from the eye contact end surface. It can be understood that the auxiliary panel 200 for opening the lower eyelid is part of the vision screening instrument. In order to connect the auxiliary panel 200 for opening the lower eyelid with the vision screening instrument, a connection structure 203 is provided at the position of the plate body 201 facing away from the eye contact end surface. In some embodiments, the connection structure 203 may be a connection column and a connection hole, one of which is provided on the auxiliary panel 200 for opening the lower eyelid, and the other is provided on the vision screening instrument. When the connection column is inserted into the connection hole, the connection between the auxiliary panel 200 for opening the lower eyelid and the vision screening instrument is realized. Specifically, the connection structure 203 may also be a connection buckle. In this embodiment, the connection structure 203 is not specifically limited.

[0052] The present invention also proposes a vision screening instrument, which includes the auxiliary panel 200 for opening the lower eyelid. The specific structure of the auxiliary panel 200 for opening the lower eyelid refers to the above-mentioned embodiment. Since the vision screening instrument adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0053] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
