It often uses infrared light sources and cameras to track pupils and obtain the position and direction of gaze. However, due to errors and efficiency issues, in order to improve the user experience, electronic devices often need to undergo extensive human eye testing. However, human eye testing is not only time-consuming and inefficient, but also easily causes eye fatigue. Utility Model Content

[0072] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0073] Reference below Figures 1-13 The simulated eyeball structure provided by an embodiment of the present application is described, and the simulated eyeball structure includes a shell 100 , a simulated iris component 200 , a simulated cornea component 300 , a simulated lens component 400 and a simulated retina component 500 .

[0074] The housing 100 forms a receiving cavity 101 with an opening. It should be noted that the shapes and sizes of the housing 100, the opening, and the receiving cavity 101 can be adjusted according to the structure and size of the actual eyeball, and this embodiment does not impose any specific restrictions on this.

[0075] The simulated iris 200 is disposed at the opening to form a simulated pupil 201 , and the aperture of the simulated pupil 201 is adjustable.

[0076] It can be understood that the aperture of the simulated pupil 201 is adjustable, thereby allowing the simulated eyeball structure to simulate the natural reaction of the simulated pupil 201 under different conditions (such as lighting, age, or degree of interest in the current scene, etc.), increasing the authenticity and adaptability of the simulated eyeball structure, and further improving the accuracy of subsequent tests.

[0077] The simulated cornea member 300 is mounted on the housing 100 and protrudes in a direction away from the opening.

[0078] For the convenience of description, the opening is set on the front side of the shell 100, the axis of the simulated pupil 201 is parallel to the front-to-back direction, and the simulated cornea component 300 is connected to the edge of the shell 100 at the opening and protrudes forward, which not only helps to simulate the refraction process of light entering the simulated eyeball, but also enables a cavity to be formed between the simulated cornea component 300 and the simulated iris component 200 for accommodating the simulated aqueous humor component 600, further ensuring the integrity and complexity of the simulated eyeball structure and improving the accuracy of subsequent tests.

[0079] The simulated lens 400 is positioned within the housing 101, adjacent to the simulated iris 200, to adjust the focal length for viewing objects at varying distances. The simulated retina 500 is positioned within the housing 101, on the side of the simulated lens 400 away from the simulated iris 200, to receive and convert optical signals to produce a clear image.

[0080] It can be understood that the simulated lens component 400 is located on the rear side of the simulated iris component 200, and the simulated retina component 500 is located on the rear side of the simulated lens component 400, that is, the simulated cornea component 300, the simulated iris component 200, the simulated lens component 400 and the simulated retina component 500 are arranged in sequence from front to back, and the aperture of the simulated pupil 201 is adjustable to more accurately replicate the optical properties and physiological reactions of the human eye, ensuring the authenticity, adaptability and practicality of the entire simulated eyeball structure, reducing fatigue and errors encountered in actual measurements by real people, and thus improving the efficiency and accuracy of subsequent tests.

[0081] According to the simulated eyeball structure provided in the embodiment of the present application, the simulated cornea component 300, the simulated iris component 200, the simulated lens component 400 and the simulated retina component 500 are arranged in sequence from front to back, and the aperture of the simulated pupil 201 is adjustable to more accurately replicate the optical properties and physiological reactions of the human eye, thereby ensuring the authenticity, adaptability and practicality of the entire simulated eyeball structure, reducing problems such as fatigue and errors encountered during actual measurements by real people, and thus improving the efficiency and accuracy of subsequent tests.

[0082] In some embodiments, as Figure 2 As shown, the simulated eyeball structure further includes a simulated aqueous humor component 600 , which is disposed on a side of the simulated iris component 200 away from the simulated lens component 400 .

[0083] It is understood that the simulated aqueous humor component 600 is located between the simulated cornea component 300 and the simulated iris component 200. Specifically, the simulated cornea component 300, the simulated aqueous humor component 600, the simulated iris component 200, the simulated lens component 400, and the simulated retina component 500 are arranged in order from front to back. The simulated aqueous humor component 600 is used to simulate the refraction of light by the aqueous humor in the human eye. For example, the refractive index of the material used to make the simulated aqueous humor component 600 is 1.336 to further enhance the realism of the simulated eyeball structure. It should be noted that the simulated aqueous humor component 600 can be solid or liquid, and this embodiment does not impose any specific limitations on this.

[0084] In some embodiments, as Figure 1 and Figure 2 As shown, the simulated cornea component 300 includes a simulated cornea layer, which is sprayed or coated on the surface of the simulated aqueous humor component 600 away from the simulated iris component 200. For example, the refractive index of the material making up the simulated cornea component 300 is 1.376 to further enhance the realism of the simulated eyeball structure.

[0085] It is understandable that forming a simulated corneal layer on the front of the outer surface of the simulated aqueous humor component 600 by spraying or coating can not only accurately control the thickness and uniformity of the simulated corneal layer, reduce the possibility of optical distortion, but also reduce production costs.

[0086] Of course, in some other embodiments, the simulated cornea component 300 can also be directly made of a material with a refractive index of 1.376, adhered to the front side of the simulated aqueous humor component 600 and connected to the edge of the opening of the shell 100. This embodiment does not impose specific restrictions on this.

[0087] In some embodiments, by coloring the material used to make the simulated iris part 200, the iris characteristics (color or texture) of different races corresponding to the human eye can be simulated, thereby increasing the diversity and applicability of the simulated eyeball structure, allowing it to better adapt to the needs of different scenarios and further improving the comprehensiveness and accuracy of the test.

[0088] In some embodiments, as Figures 3 to 6As shown, the simulated iris component 200 includes a first substrate 211 having a first opening formed therein. The simulated iris component 200 also includes a plurality of movable portions 212 spaced apart around the first opening. The free ends of the movable portions 212 collectively enclose a simulated pupil 201. When the intensity of the light received decreases, the free ends of the movable portions 212 can move away from the center of the simulated pupil 201 to expand the aperture. When the intensity of the light received increases, the free ends of the movable portions 212 can move toward the center to narrow the aperture. It should be noted that the number, shape, and size of the movable portions 212 can be designed based on actual needs and are not specifically limited in this embodiment.

[0089] It can be understood that the outer edge of the first substrate 211 is connected to the inner edge of the opening, the axis of the first opening is parallel to the front-to-back direction, the fixed end of each movable part 212 is connected to the inner edge of the first opening, and the free ends of all the spaced-apart movable parts 212 together form a simulated pupil 201.

[0090] At the same time, the movable portion 212 moves relative to the first substrate 211 according to changes in light intensity, thereby simulating the dynamic adjustment ability of the human eye to light changes, improving the simulation accuracy of the simulated eyeball structure to the real visual environment, and helping to improve the accuracy of subsequent tests.

[0091] That is, when the ambient light intensity of the simulated eyeball structure becomes smaller, such as Figure 3 and Figure 4 As shown, the free end of the movable portion 212 bends backward, thereby increasing the distance between the free ends of two adjacent movable portions 212, thereby increasing the aperture of the simulated pupil 201 and increasing the amount of light entering the front surface of the simulated lens 400, thereby simulating the pupil dilation characteristic of the human eye when viewing weak light.

[0092] When the ambient light intensity of the simulated eyeball structure increases, such as Figure 5 and Figure 6 As shown, the free end of the movable portion 212 bends forward, that is, the free end of the movable portion 212 extends toward the inner edge symmetrically arranged at the connection between the first opening and the fixed end of the movable portion 212, thereby reducing the distance between the free ends of two adjacent movable portions 212, thereby reducing the aperture of the simulated pupil 201 and reducing the amount of light entering the front surface of the simulated lens component 400, thereby simulating the characteristic of pupil constriction when the human eye sees strong light.

[0093] In other embodiments, the simulated iris component 200 may comprise only a movable portion 212 with multiple spacer rings disposed within the first opening, with the free ends of the movable portions 212 collectively enclosing the simulated pupil 201. When the intensity of the received light decreases, the free ends of the movable portions 212 may move away from the center of the simulated pupil 201 to expand the aperture. When the intensity of the received light increases, the free ends of the movable portions 212 may move toward the center to narrow the aperture. The fixed end of the movable portion 212 may be disposed on a surface of the simulated aqueous humor component 600 proximal to the simulated lens component 400, or on the inner wall of the accommodating cavity 101.

[0094] It can be understood that by arranging the fixed end spacer rings of multiple movable parts 212 on the rear surface of the simulated aqueous humor part 600, or arranging the fixed end spacer rings of multiple movable parts 212 at the inner edge of the opening, the function of the first substrate 211 is replaced, and while realizing the change in the aperture of the simulated pupil 201, it plays a role in reducing the disassembly and assembly process and reducing the manufacturing cost.

[0095] In some embodiments, as Figure 3 、 Figure 5 and Figure 6 As shown, the distance between the two side surfaces of each movable portion 212 that are arranged opposite to each other and close to the adjacent movable portion 212 gradually decreases in the direction away from the connection between the movable portion 212 and the first opening, that is, the two sides of the movable portion 212 are inclined toward the middle, thereby facilitating the fine realization of the aperture change of the simulated pupil 201. It should be noted that the angle of the side inclination of the movable portion 212 can be designed according to actual needs, not only as Figure 5 As shown, it can simulate the pupil of the human eye to be reduced to the minimum aperture, and can also be Figure 6 As shown, the situation where the aperture is approximately 0 is simulated, further expanding the adjustable range of the aperture of the simulated pupil 201, thereby improving the use range and adaptability of the simulated eyeball structure.

[0096] In some embodiments, as Figures 3 to 6 As shown, the movable portion 212 is made of a photosensitive material so as to bend to different degrees when exposed to different light intensities to adjust the aperture. The photosensitive material includes but is not limited to photorefractive crystals.

[0097] It can be understood that, by mounting the fixed end of the movable portion 212 made of a photosensitive material on the inner edge of the first opening, the free end of the movable portion 212 can be deformed autonomously according to changes in light intensity, that is, when the ambient light intensity of the simulated eyeball structure decreases, the eyeball structure is deformed. Figure 3 and Figure 4As shown, the free end of the movable portion 212 bends backward and outward to be as far away from the first opening as possible and close to the rear surface of the first substrate 211, thereby increasing the distance between the free ends of two adjacent movable portions 212, thereby increasing the aperture of the simulated pupil 201; when the ambient light intensity of the simulated eyeball structure increases, as shown in FIG. Figure 5 and Figure 6 As shown, the free end of the movable portion 212 extends toward the center of the first opening, thereby reducing the distance between the free ends of two adjacent movable portions 212 , thereby reducing the aperture of the simulated pupil 201 .

[0098] It should be noted that, no matter whether the first substrate 211 is provided or not, the movement process of the free end of the movable portion 212 is similar.

[0099] In some other embodiments, the simulated iris component 200 further includes a light sensor for obtaining light intensity on a side of the movable portion 212 close to the simulated cornea component 300 to drive the free end of the movable portion 212 to bend accordingly to adjust the aperture.

[0100] It can be understood that the light sensor measures the intensity of light entering the simulated eyeball structure in real time and sends a signal according to the detected intensity of light, thereby achieving the corresponding bending of the free end of the movable portion 212, that is, when the intensity of ambient light in the simulated eyeball structure becomes smaller, such as Figure 3 and Figure 4 As shown, the free end of the movable portion 212 bends backward and outward to be as far away from the first opening as possible and close to the rear surface of the first substrate 211, thereby increasing the distance between the free ends of two adjacent movable portions 212, thereby increasing the aperture of the simulated pupil 201; when the ambient light intensity of the simulated eyeball structure increases, as shown in FIG. Figure 5 and Figure 6 As shown, the free end of the movable portion 212 extends toward the center of the first opening, thereby reducing the distance between the free ends of two adjacent movable portions 212 , thereby reducing the aperture of the simulated pupil 201 .

[0101] It should be noted that, no matter whether the first substrate 211 is provided or not, the movement process of the free end of the movable portion 212 is similar.

[0102] In some embodiments, the simulated iris member 200 further includes a first driver communicatively connected to the light sensor. The driving end of the first driver is connected to the free ends of each movable portion 212, and is configured to drive the free ends of each movable portion 212 to move synchronously. Specifically, the first driver can adjust the movable portion 212 based on the light intensity detected by the light sensor, thereby achieving changes in the aperture of the simulated pupil 201 under varying light intensity. It should be noted that the first driver can be at least one of an electric driver and a manual driver, thereby facilitating flexible selection of the driving method for the movable portion 212 based on different application scenarios and user needs.

[0103] In some embodiments, as Figure 7 As shown, the simulated iris component 200 includes a second substrate 221 and a rotating disk 222. The second substrate 221 is provided with a second opening forming the simulated pupil 201. The rotating disk 222 has at least two adjustment holes 2221 spaced apart and having different apertures. The axes of the adjustment holes 2221 are parallel to the axis of the simulated pupil 201. The rotating disk 222 is rotatably mounted on one side of the second substrate 221 and can rotate to align the axis of the desired adjustment hole 2221 with the axis of the simulated pupil 201, thereby achieving aperture adjustment. It should be noted that the number and size of the adjustment holes 2221 can be designed according to actual needs and are not specifically limited in this embodiment.

[0104] For example, if the axis of the adjusting through hole 2221 with a smaller aperture is selected to be aligned with the axis of the simulated pupil 201, the actual aperture of the simulated pupil 201 will become smaller; if the axis of the adjusting through hole 2221 with a larger aperture is selected to be aligned with the axis of the simulated pupil 201, the actual aperture of the simulated pupil 201 will become larger.

[0105] It can be understood that the outer edge of the second substrate 221 is connected to the inner edge of the opening, and the turntable 222 is rotatably arranged on the front or rear side of the second substrate 221, and the rotation axis of the turntable 222 is parallel to the front-to-back direction, and the axis of the adjustment hole 2221 is parallel to the front-to-back direction. At least two adjustment holes 2221 are spaced apart and arranged outside the rotation center of the turntable 222, that is, by rotating the turntable 222, the axis of the adjustment hole 2221 with different apertures can be selected to be aligned with the axis of the simulated pupil 201, that is, along the front-to-back direction, the projection of the surface of the turntable 222 at the edge of the adjustment hole 2221 can block part of the simulated hole, thereby changing the actual aperture of the simulated pupil 201 to simulate the changes in the human pupil under different conditions (such as age or light intensity).

[0106] In this embodiment, the turntable 222 is located on a side of the second substrate 221 away from the simulated aqueous humor component 600. Specifically, the turntable 222 is rotatably positioned on the rear side of the second substrate 221. This prevents the turntable 222 from affecting the position or volume of the simulated aqueous humor component 600, facilitates maintenance and control of the turntable 222's rotation, and helps improve the accuracy of the simulated eyeball structure and the human eye. Of course, in other embodiments, the turntable 222 can also be located on a side of the second substrate 221 closer to the simulated aqueous humor component 600, and this embodiment does not impose any specific limitations on this.

[0107] In some embodiments, as Figure 7 As shown, the aperture of the simulated pupil 201 is not less than the aperture of any adjustment through hole 2221, thereby ensuring that light always passes through the simulated pupil 201, so as to achieve a more realistic simulation of the physiological response of the human eye.

[0108] Similarly, the simulated iris member 200 also includes a second driver. A turntable 222 is mounted on the driver end of the second driver for rotating the turntable 222. Specifically, the second driver can adjust the rotation angle and direction of the turntable 222 as needed, thereby varying the aperture of the simulated pupil 201 under different conditions. It should be noted that the second driver can be at least one of an electric driver and a manual driver, facilitating flexible selection of the driving method for the turntable 222 based on different application scenarios and user needs.

[0109] In some embodiments, as Figure 8 As shown, the simulated iris 200 includes at least two adjustment portions 231. The adjacent sides of the adjustment portions 231 each form a notch, which together encloses the simulated pupil 201. The adjustment portions 231 can move closer or farther away from each other along the radial direction of the simulated pupil 201. It should be noted that the shape of the notch includes, but is not limited to, a square, a triangle, or an ellipse. In other words, the shape of the simulated pupil 201 can be square, diamond, or elliptical, and this embodiment does not impose any specific limitation on this.

[0110] It can be understood that when the adjustment parts 231 are close to each other, the aperture of the simulated pupil 201 formed by the gap becomes smaller; when the adjustment parts 231 are away from each other, the aperture of the simulated pupil 201 formed by the gap becomes larger, so as to simulate the changes in the human pupil under different conditions (such as age or light intensity).

[0111] In this embodiment, Figure 8As shown, the simulated iris 200 includes two opposing adjustment portions 231. Specifically, each adjustment portion 231 forms a notch near the other side. When the two adjustment portions 231 move closer together, the aperture of the simulated pupil 201 formed by the two notches decreases. When the two adjustment portions 231 move away from each other, the aperture of the simulated pupil 201 formed by the two notches increases, thereby simulating changes in the human pupil under different conditions (such as age or light intensity). Of course, in other embodiments, three or more adjustment portions 231 may be provided, and this embodiment does not specifically limit this.

[0112] Similarly, the simulated iris member 200 also includes a third actuator. An adjustment portion 231 is mounted on the actuator end of the third actuator, which is used to drive the multiple adjustment portions 231 toward or away from each other. This means that the third actuator can adjust the distance between the adjustment portions 231 as needed, thereby varying the aperture of the simulated pupil 201 under different conditions. It should be noted that the third actuator can be at least one of an electric actuator and a manual actuator, allowing for flexible selection of the actuator method for the adjustment portions 231 based on different application scenarios and user needs.

[0113] In some embodiments, as Figures 9 to 11 As shown, the simulated iris 200 includes a third substrate 241, a fourth substrate 242, and a plurality of mating portions 243. The third substrate 241 defines a third opening 2411 and a plurality of slide grooves 2412 disposed outside the third opening 2411. The fourth substrate 242 is spaced apart from the third substrate 241 and rotates relative to it. The fourth substrate 242 defines a fourth opening 2421 aligned with the axis of the third opening 2411. The mating portions 243 are mounted between the third and fourth substrates 241, 242, and are arranged to form the simulated pupil 201. Each mating portion 243 corresponds to a slide groove 2412 and can slide within the slide groove 2412 to adjust the aperture. It should be noted that the number of mating portions 243 can be designed based on actual needs and is not specifically limited in this embodiment.

[0114] It is understood that the axes of the third opening 2411 and the fourth opening 2421 coincide with each other and are parallel to the front-to-back direction, ensuring alignment of the fourth substrate 242 and the third substrate 241 during relative rotation. By rotating the fourth substrate 242 or the third substrate 241, one side of each mating portion 243 moves back and forth along the length of the slot 2412, thereby changing the aperture of the simulated pupil 201 formed by the other sides of all the mating portions 243, thereby simulating changes in the human pupil under different conditions (such as age or light intensity).

[0115] It should be noted that, in this embodiment, Figures 9 to 11As shown, the fourth substrate 242, the matching portion 243 and the third substrate 241 are arranged in sequence from front to back. Of course, in other embodiments, the third substrate 241, the matching portion 243 and the fourth substrate 242 are arranged in sequence from front to back, and this embodiment does not make specific limitations on this.

[0116] In some embodiments, as Figure 11 As shown, the mating portion 243 includes a rotating vane and a rotating shaft 2432. The first surface 24311 of the rotating vane slidably engages with a surface of the third substrate 241 adjacent to the fourth substrate 242, while the second surface of the rotating vane is mounted on a surface of the fourth substrate 242 adjacent to the third substrate 241. The rotating shaft 2432 protrudes from the first surface 24311 of the rotating vane and is slidably hinged to a corresponding sliding groove 2412. It should be noted that the connection between the rotating vane and the fourth substrate 242 includes, but is not limited to, welding, threaded connection, or clamping.

[0117] It can be understood that the rotating shaft 2432 protruding from the first surface 24311 of the rotating blade moves and rotates in the slide groove 2412, that is, when the rotating shaft 2432 moves in the slide groove 2412 toward the center of the third opening 2411, the aperture of the simulated pupil 201 formed between the rotating blades becomes larger; when the rotating shaft 2432 moves in the slide groove 2412 toward the center of the third opening 2411, the aperture of the simulated pupil 201 formed between the rotating blades becomes smaller.

[0118] In some embodiments, as Figure 11 As shown, the rotary blade has an inner arc surface 24313 and an outer arc surface 24314 that are relatively arranged. The inner arc surface 24313, the first surface 24311, the outer arc surface 24314 and the second surface are connected end to end in sequence. The part of the inner arc surface 24313 away from the rotating shaft 2432 forms a part of the inner edge of the simulated pupil 201 to further ensure the authenticity of the formed simulated pupil 201 and the accuracy of the aperture adjustment.

[0119] In some embodiments, as Figure 11 As shown, the curvature radius of the inner arc surface 24313 is smaller than the curvature radius of the outer arc surface 24314 , thereby further reducing the friction between the rotor and the third substrate 241 and the rotor.

[0120] Similarly, the simulated iris component 200 also includes a fourth driver. A fourth substrate 242 is mounted on the driver end of the fourth driver for driving the rotation of the fourth substrate 242. Specifically, the fourth driver can adjust the rotation angle and direction of the fourth substrate 242 as needed, thereby achieving variations in the aperture of the simulated pupil 201 under different conditions. It should be noted that the fourth driver can be at least one of an electric driver and a manual driver, thereby facilitating flexible selection of the driving method for the fourth substrate 242 based on different application scenarios and user needs. Of course, in other embodiments, the driver end of the fourth driver can also be mounted on the third substrate 241, as long as relative rotation between the third substrate 241 and the fourth substrate 242 is ensured. This is not specifically limited in this embodiment.

[0121] In some embodiments, in order to make the simulated lens element 400 have the function of simulating the human eye lens, three implementation modes are provided:

[0122] First, as Figure 12 As shown, the simulated lens component 400 includes a multifocal intraocular lens 410 , which is disposed in the accommodating cavity 101 .

[0123] It can be understood that the multifocal intraocular lens 410 is installed in the accommodating cavity 101 and is located behind the simulated pupil 201. The multifocal intraocular lens 410 is an optical lens that uses the optical principle of refraction or diffraction to separate the light incident on the surface of the multifocal intraocular lens 410 through the simulated pupil 201, generating multiple focal points to focus on the simulated retinal component 500, thereby always obtaining a clear image.

[0124] In some embodiments, as Figure 12 As shown, the multifocal intraocular lens 410 includes a plurality of radially spaced diffraction steps 411 on a surface facing away from the simulated iris element 200. These steps are used to generate multiple diffraction orders or focal points on the optical axis, so that when an object associated with an image is located at a corresponding distance from the eye, the image focal point is formed on the simulated retina element 500. It should be noted that the number and shape of the diffraction steps 411 can be designed based on actual needs and are not specifically limited in this embodiment. For example, the shape of the diffraction steps 411 includes, but is not limited to, an annular shape.

[0125] Second, in some embodiments, the simulated lens 400 includes a first lens, which is movably disposed in the accommodating cavity 101 along the axis of the simulated pupil 201 .

[0126] It is understandable that by moving the first lens in the front-to-back direction, the focal length can be dynamically adjusted, thereby simulating the focal length change of the human eye when observing objects at different distances, so as to further improve the authenticity of the simulated eyeball structure.

[0127] Similarly, the simulated iris component 200 also includes a fifth driver. The first lens is mounted on its driving end and is used to drive the movement of the first lens. This means that the fifth driver can adjust the movement distance and direction of the first lens as needed, simulating the change in focal length of an object at different distances. It should be noted that the fifth driver can be at least one of an electric driver and a manual driver, facilitating flexible selection of the driving method for the first lens based on different application scenarios and user needs.

[0128] Third, in some embodiments, as Figure 13 As shown, the simulated lens 400 includes a plurality of second lenses 420 distributed in an array, and the vertical distance between the center of each second lens 420 and the center of the simulated pupil 201 along the axis of the simulated pupil 201 is the same. It should be noted that the number, shape, and size of the second lenses 420 can be designed according to actual needs and are not specifically limited in this embodiment.

[0129] It can be understood that the multiple second lenses 420 are distributed in an array, and the vertical distance between the center of each second lens 420 and the center of the simulated pupil 201 along the axis of the simulated pupil 201 is the same, that is, the multiple second lenses 420 are distributed in the up and down direction to form a lens group, and the multiple lens groups are distributed in the left and right direction, so as to simulate the gradient refractive characteristics of the human eye lens, so that for the same object, each second lens 420 can obtain a corresponding image on the simulated retinal component 500, so that all the images can be processed and analyzed later to obtain a clear image corresponding to the object, so as to achieve a clear image of the object without the need for a fifth driving component.

[0130] It should be noted that the size of a single second lens 420 is much smaller than that of the first lens.

[0131] In some embodiments, the simulated retina component 500 includes a photosensitive element, which is attached to the inner wall portion of the accommodating cavity 101 away from the opening.

[0132] It can be understood that the photosensitive element is attached to the inner wall portion of the accommodating cavity 101 away from the opening, that is, the photosensitive element is attached to the rear part of the accommodating cavity 101, thereby simulating the position of the human eye's retina, and using the photosensitive element to convert the received light signal into an electrical signal, thereby simulating the process of the human eye's retina converting the light signal into a neural signal, so as to further improve the authenticity of the simulated eyeball structure.

[0133] In some embodiments, the simulated retina device 500 further includes a microprocessor in communication with the photosensitive element. The microprocessor is configured to receive and process electrical signals from the photosensitive element to obtain visual information. The microprocessor can also communicate with an external device (such as a tablet, computer, or smart phone) via wireless (Bluetooth transmission or drone transmission) or wired communication, enabling the simulated eye structure to have camera-like photography and image processing capabilities, thereby simulating the brain's process of receiving and processing visual information obtained by the human eye, further enhancing the realism of the simulated eye structure.

[0134] It should be noted that visual information includes image information and video information.

[0135] The embodiment of the present application further provides a testing device, which includes the above-mentioned simulated eyeball structure.

[0136] According to the test device provided in the embodiment of the present application, the simulated cornea component 300, the simulated iris component 200, the simulated lens component 400 and the simulated retina component 500 in the simulated eyeball structure are arranged in sequence from front to back, and the aperture of the simulated pupil 201 is adjustable to more accurately replicate the optical properties and physiological reactions of the human eye, thereby ensuring the authenticity, adaptability and practicality of the entire simulated eyeball structure, reducing problems such as fatigue and errors encountered during actual measurements by real people, and thus improving the efficiency and accuracy of the test.

[0137] In some embodiments, the testing device further includes a driving device and a control device, wherein the driving device is used to drive the movement of the simulated eyeball structure, and the control device is communicatively connected to the simulated eyeball and the driving device respectively.

[0138] It can be understood that the driving device enables the simulated eyeball structure to simulate human eye movements, such as gaze, tracking, and scanning, and the control device is responsible for coordinating and controlling the driving device and the simulated eyeball structure to achieve complex eye tracking simulation and testing.
