The camera part 21 may include multiple cameras and a camera mounting cover. The camera mounting cover may be arranged in a honeycomb shape, and multiple cameras may be arranged on the camera mounting cover so that the multiple cameras are combined in a honeycomb shape. The camera mounting cover can automatically adjust the camera shooting distance and angle under the control of the control component to make the pictures output by the camera part 21 clearer, which is convenient for identifying eye symptoms.

[0054] Among them, multiple cameras can have a certain magnification, and the magnification can be set according to the slit lamp magnification. The optical magnification can be set to 8 to 40 times, or the magnification can be infinitely variable. In addition, each camera has an independent focus function, which can be suitable for different people to perform eye surface anatomical details, and finally form an overall three-dimensional clear picture to the video terminal, which is magnified and displayed in real time.

[0055] In some embodiments, as shown in Figure 2, the control component may include a first circuit board, and the display component 30 may include a transparent display screen 31. The transparent display screen 31 may be electrically connected to the first circuit board. The transparent display screen 31 can be used to display a visual mark, and the visual mark can be used to be followed by the eyes so that the eyes move with the icon, allowing the camera to capture pictures of the eyes in more states.

[0056] Among them, the sight mark can be set as a circular icon, a ring icon, an animated icon, etc. The circular icon can guide the patient's eyes to follow the sight mark, and can perform ocular surface and fundus examinations according to changes in eye position; the ring icon is similar to a corneal topography, and can be used for corneal topography, tear film rupture time and other examinations; the animated icon can attract younger children to cooperate in completing eye examinations.

[0070] The microphone 42 may also be a microphone or earphones, and the microphone can provide voice prompts and give corresponding prompts according to the patient's answers.

[0071] As shown in FIG3 , the headband portion 40 may include a headband body 43 and a fixing strap 44 . The headband body 43 may be arranged in a circular shape, and the fixing strap 44 may be arranged above the headband body 43 to make the multi-lens ophthalmic examination device more stable when worn on the head.

[0072] Please refer to Figures 5 to 10, Figure 5 is a flow chart of the multi-lens ophthalmic examination method of the present application; Figure 6 is a specific flow chart of step S100 in Figure 5; Figure 7 is a specific flow chart of step S100 in Figure 5; Figure 8 is a flow chart before step S200 in Figure 5; Figure 9 is a specific flow chart of step S200 in Figure 5; Figure 10 is a structural schematic diagram of the preset orientation in step S210.

[0073] The present application also proposes a multi-lens ophthalmic examination method based on a multi-lens ophthalmic examination device, as shown in FIG5 . The multi-lens ophthalmic examination method includes:

[0074] Step S100: After the inspection distance between the multi-lens ophthalmic inspection device and the inspected person's eyes is adjusted, the display component displays an optotype so that the eyes can focus on the optotype;

[0075] Step S200: the camera assembly photographs the eyes to obtain a plurality of eye images;

[0076] Step S300: The control component performs mosaic processing on all the eye images to obtain a panoramic image of the eye retina.

[0077] Specifically, first, the inspection distance between the multi-lens ophthalmic examination equipment and the eyes of the examinee can be adjusted so that the optimal shooting distance can be achieved between the multi-lens ophthalmic examination equipment and the eyes of different examinees according to different conditions of different examinees, so that the captured eye pictures are clearer, and the display component is controlled to display the sight mark so that the eyes look at the sight mark, or follow the sight mark to make the eyes show different states under different viewing angles, and the camera component is controlled to shoot the eyes to obtain a series of eye pictures under different viewing angles, and all the eye pictures are pieced together to obtain a panoramic picture of the eye retina. The eye pictures that can be obtained are more comprehensive, and there will be no occasional omissions that may occur in manual inspection.

[0078] In some embodiments, as shown in FIG6 , the step S100 of displaying an optotype on the display assembly after adjusting the inspection distance between the multi-lens ophthalmic inspection device and the examinee's eyes so that the examinee's eyes focus on the optotype specifically includes:

[0079] Step S110: After the inspection distance between the multi-lens ophthalmic inspection device and the inspected person's eyes is adjusted to 3-5 cm, the display component displays an optotype so that the eyes can focus on the optotype.

[0080] Specifically, the multi-lens ophthalmic examination equipment is worn on the head of the person being examined, and the distance between the display component and the eyes is adjusted to 3 to 5 cm. At this distance, the eyes can better focus on the transparent display screen, so that the eyes can pay more attention. The focal length of the camera can also be better adjusted to achieve better shooting effects. The above distance also makes it easier for the doctor to perform operations such as lifting the eyelids of the person being examined, and the captured image will not be blurred due to changes in the patient's head position or body position.

[0081] The distance between the eyes and the transparent display can be adjusted to 3cm, 3.5cm, 4cm, 4.5cm and 5cm. The above distances can be selected according to the conditions of different patients (such as age, sitting or standing posture during measurement, etc.) to achieve the best shooting effect.

[0082] Among them, after the examinee wears the multi-lens ophthalmic examination equipment as required, the distance between each component is adjusted, such as the distance between the inner transparent display screen and the eyes, the distance between the multiple outer cameras and the eyes, and the distance between the inner transparent display screen and the multiple outer cameras, to ensure that the inner transparent display screen has no contact with the eyes, the camera shoots the eyes as the center of the image, and the focal length of the camera is fine-tuned to make the image clearer.

[0083] In some embodiments, as shown in FIG7 , the step S100 of displaying an optotype on the display assembly after adjusting the inspection distance between the multi-lens ophthalmic inspection device and the examinee's eyes so that the examinee's eyes focus on the optotype specifically includes:

[0084] Step S120: After the inspection distance between the multi-lens ophthalmic inspection device and the inspected person's eyes is adjusted, the display component displays the sight mark in a first shape, so that the eyes can focus on the first shape.

[0085] Specifically, the first shape can be a flower or a small animal shape, so that the sight mark attracts the eyes' attention. If the person being examined is a child, setting the sight mark in the shape of a flower or a small animal can well attract the examinee's attention.

[0086] Among them, the first shape can also be set to a conventional circular light spot, or the sight mark can be controlled to change the eye position according to different directions, thereby increasing the shooting area and obtaining more pictures.

[0087] In some embodiments, as shown in FIG8 , the step S200 of controlling the camera assembly to photograph the eyes to obtain a plurality of eye images further includes:

[0088] Step S130: The light source emits outgoing light, so that the outgoing light illuminates the eye.

[0089] Specifically, the light source is controlled to emit light so that it illuminates the eye. The light source can emit slit light bands, diffuse light, green light, infrared light, cobalt blue light, etc. The different light sources can facilitate examinations of the anterior and posterior segments of the eye, or emit the most favorable light for different diseases, making the examination more accurate. For example, when the light source emits infrared light, the doctor can flip the examinee's eyelids and use the camera to take a picture of the meibomian glands. Under the infrared light, the meibomian glands can be clearly displayed on the camera. Alternatively, the light source can emit different light beams, so that different images of the eye are captured under different lighting conditions, leading to more accurate diagnosis of ophthalmic diseases.

[0090] In some embodiments, as shown in FIG9 and FIG10 , the step S200 of controlling the camera assembly to photograph the eyes to obtain a plurality of eye images specifically includes:

[0091] Step S210: the camera assembly photographs the eyes respectively according to preset positions to obtain a plurality of eye images corresponding to the preset positions.

[0092] Specifically, the camera assembly is adjusted to capture the eyes in preset positions, and a series of eye images corresponding to the preset positions are obtained. Different lenses can be focused on different examination sites according to the doctor's requirements for disease examination. The preset positions for the front of the eye examination can be set with different examination points according to the partial anatomical structures shown in FIG10 . The preset positions may include the conjunctiva 51, sclera 52, anterior surface of the cornea 53, posterior surface of the cornea 54, anterior chamber 55, pupil 56, iris 57, anterior lens capsule 58, lens nucleus 59, posterior lens capsule 60, The anterior vitreous body 61, the middle vitreous body 62, the posterior vitreous body 63, the retina 64, the choroid 65, the macula 66 and the optic disc 67. The posterior eye examination can take pictures of the eye at the middle vitreous body 62, the posterior vitreous body 63, the retina 64, the choroid 65, the macula 66, the optic disc 67 and other positions at one time according to the preset direction. The panoramic retinal 64 examination can focus on the retina 64 according to the required shooting part and shoot it. After using multiple lenses to shoot from different directions, the mosaic process is performed to obtain a panoramic retinal 64 picture.

[0093] Optionally, the cornea may be dyed and the dyed cornea may be photographed to obtain a more accurate picture of the eye.
