Technical Field

[0001] The utility model generally relates to the technical field of myopia therapy, and more specifically relates to a red light irradiation device for myopia therapy. Background Art

[0002] In recent years, with the popularization of electronic screen scenes, the increase in students' study pressure and duration, the problem of myopia among young people has become more and more serious. In terms of myopia prevention and control, the method generally recognized by the domestic medical community is to delay the progression of myopia by irradiating the fundus with low-intensity red light. Usually, the main components of low-intensity red light irradiation equipment are two lens barrels, each of which irradiates the pupil of one eye. Among them, the movement of the eyeball relative to the red light irradiation lens barrel can be in multiple directions, and the movement in each direction will cause the intensity and distribution of the light entering the pupil to illuminate the fundus to change, thereby deviating from the ideal value. However, traditional red light irradiation equipment requires the user to manually or electrically adjust the relative position between the eyeball and the red light irradiation lens barrel or the pupil distance of the eyeball, which makes the traditional red light irradiation equipment low in intelligence, reduces the irradiation efficiency, and also affects the irradiation effect.

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. It should be understood that the embodiments described in this specification are only partial embodiments provided by the utility model to facilitate a clear understanding of the solutions and to comply with legal requirements, and are not all embodiments that can implement the utility model. Based on the embodiments disclosed in this specification, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] As described in the above background technology, the movement of the eyeball relative to the red light irradiation lens barrel can be in multiple directions. Movement in each direction will cause the intensity and distribution of the light entering the pupil to illuminate the fundus to change, thereby deviating from the ideal value and reducing the irradiation effect. It is understandable that since the tissue of the fundus is relatively fragile, doctors usually design the best irradiation effect to control the red light irradiation of the fundus. Among them, when designing the best irradiation effect, it can usually be assumed that the relative position between the eyeball and the lens of the red light irradiation device is fixed. In this scenario, if the aforementioned relative position changes, the irradiation effect will be different and decrease. The following will combine Figure 1a-1f Describe the differences in illumination effects corresponding to several different relative positions.

[0024] Figure 1a-1fis an exemplary schematic diagram showing the differences in illumination effects corresponding to several different relative positions. Figure 1a As shown in , it is assumed that the relative position, direction and distance between the red light irradiation lens barrel 101 and the eyeball 102 are all in an ideal state, that is, the central axis of the red light irradiation lens barrel 101 coincides with the central axis of the ocular surface (e.g., pupil) 105, the central axis is perpendicular to the tangent plane of the ocular surface (e.g., pupil) 105, and the distance between the red light irradiation lens barrel 101 and the ocular surface (e.g., pupil) 105 makes the red light energy falling on the fundus (i.e., the effective utilization rate of red light) reach the designed expected threshold. When irradiating, the red light is provided by the red light source 103 in the red light irradiation lens barrel 101, and irradiated to the ocular surface (e.g., pupil) 105 and the fundus 106 through the front lens group (e.g., lens or plane mirror) 104. In this scenario, the energy and energy distribution of the red light falling on the fundus 106 or the ocular surface 105 are in an ideal state. That is, the irradiation effect is optimal.

[0025] Compared with the above Figure 1a The ideal state shown, Figure 1b The relative direction and distance between the red light irradiation lens barrel 101 and the eyeball 102 shown in the figure remain unchanged, but the relative position deviates, for example, the eye surface (such as the pupil) 105 moves upward for a distance relative to the central axis of the red light irradiation lens barrel 101. In this scenario, since part of the red light deviates from the eye surface (such as the pupil) 105, the energy and energy distribution of the red light falling into 106 or the eye surface 105 are less, resulting in reduced irradiation effect.

[0026] Compared with the above Figure 1a The ideal state shown, Figure 1c The relative position and direction between the red light irradiation lens barrel 101 and the eyeball 102 shown in the figure remain unchanged, but the relative distance changes, for example, the distance between the red light irradiation lens barrel 101 and the eyeball 102 increases. In this scenario, the energy and energy distribution of the red light falling on the fundus 106 or the ocular surface 105 are also less, resulting in a reduced irradiation effect.

[0027] Compared with the above Figure 1a The ideal state shown, Figure 1d The relative position and distance between the red light irradiation lens barrel 101 and the eyeball 102 shown in the figure remain unchanged, but the relative direction changes, for example, the eye surface (such as the pupil 105) is shifted upward, so that the angle between the central axis of the red light irradiation lens barrel 101 and the tangent plane of the eye surface (such as the pupil) 105 is greater than 90°. In this scenario, the energy and energy distribution of the red light falling on the fundus 106 or the eye surface 105 are less, resulting in a reduced irradiation effect.

[0028] Figure 1eIt shows the relative position of the two eyes, such as the pupil distance. In this scenario, when the pupil distance between the two eyes changes, the energy and energy distribution of the red light falling on the fundus or the ocular surface will be less, resulting in a reduced illumination effect.

[0029] In addition to the above relative positions and directions of the ocular surface (e.g., pupil), pupil size also affects the irradiation effect, e.g. Figure 1f Compared with the above Figure 1a The ideal state shown, Figure 1f The relative position, direction and distance between the red light irradiation lens barrel 101 and the eyeball 102 shown are unchanged, but the pupil 105 is smaller. In this case, the ability of the red light to pass through the pupil and enter the fundus is reduced, resulting in a reduced irradiation effect.

[0030] In the implementation scenario, the traditional red light irradiation device requires the user to manually or electrically adjust the relative position, distance or pupil distance between the eyeball and the red light irradiation lens barrel, so that the relative position, distance or pupil distance is at an ideal value, which greatly reduces the irradiation efficiency. In addition, the relative position, distance or pupil distance is only a relatively simple situation in the XYZ direction movement, and for more complex situations (such as direction changes, pupil size), it cannot be achieved by traditional red light irradiation equipment. Based on this, the utility model provides a red light irradiation device to improve the irradiation efficiency and accurately and timely adjust the red light irradiation component to the ideal position to ensure a good irradiation effect.

[0031] The following will be combined Figure 2-Figure 8 The red light irradiation device according to the embodiment of the utility model is described in detail.

[0032] Figure 2 2 is an exemplary structural block diagram showing a red light irradiation device 200 for myopia treatment according to an embodiment of the present invention. Figure 2 As shown in FIG. 2 , the red light irradiation device 200 may include a red light irradiation component 201, a positioning component 202 and a moving component 203. The red light irradiation component 201, the positioning component 202 and the moving component 203 will be described in detail below.

[0033] In one embodiment, the red light irradiation component 201 can be used to irradiate the fundus with red light. In an implementation scenario, the red light irradiation component 201 may include but is not limited to a red light source and a lens group. Among them, the aforementioned red light source can be used to provide red light to irradiate the surface of the eyeball (i.e., the ocular surface) or the fundus. The aforementioned lens group may include a front lens group and a rear lens group, and the front lens group and the rear lens group may each include one or more lenses (e.g., convex lenses and / or concave lenses) or plane mirrors. In the implementation scenario, the aforementioned front lens group is arranged in front of the red light source, and the rear lens group is arranged behind the red light source, so as to irradiate the red light to the fundus, thereby irradiating the fundus with red light.

[0034] In one embodiment, the positioning component 202 can be used to collect ocular surface images and determine positioning information based on the ocular surface images. The positioning component 202 may include at least two cameras and an image analysis module. In the implementation scenario, the at least two cameras may be arranged on both sides of the red light irradiation component 201. The specific positions of the two cameras at the red light irradiation component 201 and the angles relative to the red light irradiation component 201 may be set according to the actual scenario, and the utility model does not limit this. Based on the aforementioned arrangement, the at least two cameras may be used to collect ocular surface images from different angles. Furthermore, the ocular surface images at different angles may be analyzed via the image analysis module to obtain ocular surface features, and then determine positioning information based on the ocular surface features.

[0035] For example, firstly, two ocular surface images at different angles can be detected by an image analysis module to obtain ocular surface features. Then, the spatial position of the ocular surface feature is calculated by the difference in the position of the same ocular surface feature detected on the two ocular surface images, so as to determine the positioning information according to the spatial position of the ocular surface feature. Based on the determined positioning information, the distances in which each direction deviates from the ocular surface feature can be reflected. Therefore, the red light irradiation component 201 can be moved in one or more moving directions based on the distances in which each direction deviates from the ocular surface feature, so as to adjust the red light irradiation component 201 to the target position to irradiate the fundus.

[0036] In some embodiments, it is also possible to determine whether the red light irradiation component has moved to the ideal position based on the target position. If it is not in the ideal position, continue to collect ocular surface images to determine the spatial position of ocular surface features; if it is in the ideal position, it is also possible to determine whether the pupil size and shape are in an ideal state. If so, red light is irradiated to the fundus. On the contrary, when the pupil size and shape are not in an ideal state (for example, the pupil is small), the user can be reminded to adjust the fundus state, such as reminding the user to "open their eyes wide" or "look forward", and then collect ocular surface images again, and repeat the above operations until the ideal state or ideal position is met. Based on this, positioning information can be obtained in real time, and the red light irradiation component can be adjusted accurately and timely to ensure a good irradiation effect.

[0037] In some embodiments, the image analysis module may include but is not limited to a neural network model, for example, a computer vision model. The ocular surface features may include but are not limited to the position, direction, shape and / or size of the pupil or iris.

[0038] In one embodiment, the above-mentioned moving component 203 may include at least one moving platform, which moves along a moving direction corresponding to it, and the moving component 203 is operated to move the red light irradiation component in at least one moving direction based on the positioning information, so that the red light irradiation component performs red light irradiation on the fundus. In an implementation scenario, the above-mentioned moving component 203 may include a plurality of moving platforms, wherein the plurality of moving platforms are slidably connected and the plurality of moving platforms are operated to move the red light irradiation component along the respective corresponding moving directions to achieve red light irradiation of the fundus. As an example, the above-mentioned plurality of moving platforms may include, for example, a first moving platform, a second moving platform, and a third moving platform. The first, second, and third moving platforms are slidably connected and the red light irradiation component is arranged on the first moving platform, and the first, second, and third moving platforms are operated to move the red light irradiation component along the respective corresponding moving directions to achieve red light irradiation of the fundus.

[0039] In an exemplary scenario, the first mobile platform can be arranged on the second mobile platform and moved on the second mobile platform via the first transmission mechanism to move the red light irradiation component in the first direction. In one embodiment, the first transmission mechanism may include a first transmission device and a first transmission track, which is arranged on the second mobile platform and extends in the first direction. Among them, the first transmission device can be used to drive the first mobile platform to move on the first transmission track to move the red light irradiation component in the first direction. Specifically, the first transmission track can be arranged on the second mobile platform and extend in the vertical direction of the plane where the second mobile platform is located. In this case, the first transmission mechanism drives the first mobile platform to move in the vertical direction along the plane where the second mobile platform is located to move the red light irradiation component in the first direction (for example, the Z direction).

[0040] In one embodiment, the second mobile platform is arranged above the third mobile platform via a second transmission mechanism, and moves above the third mobile platform via the second transmission mechanism to move the red light irradiation component in the second direction. In an implementation scenario, the second transmission mechanism may include a second transmission device and a second transmission track, and the second transmission track extends along the second direction. Among them, the second transmission device can be used to drive the second mobile platform to move on the second transmission track to move the red light irradiation component in the second direction. In an exemplary scenario, the second transmission track can be arranged vertically on the third mobile platform. In this case, the second transmission device drives the second mobile platform to move vertically above the third mobile platform to move the red light irradiation component in the second direction (for example, the Y direction).

[0041] In one embodiment, the third mobile platform can be moved on, for example, a base via a third transmission mechanism to move the red light irradiation component in a third direction. In an implementation scenario, the third transmission mechanism may include a third transmission device and a third transmission track, the third transmission track being arranged on the base, and the third transmission track extending along the third direction. Among them, the third transmission device can drive the third mobile platform to move on the third transmission track to move the red light irradiation component in the third direction. In an exemplary scenario, the third transmission track may extend in the horizontal direction of the plane where the base is located. In this case, the third transmission mechanism drives the third mobile platform to move in the horizontal direction of the plane where the third mobile platform is located to move the red light irradiation component in a third direction (e.g., X direction).

[0042] In some embodiments, the first, second and third transmission devices may be, for example, motors or electromagnets, and the first, second and third transmission paths may be, for example, slideways, slide rails or slide bars. Thus, the first and second mobile platforms or sliding brackets are driven by motors (or electromagnets) to move on corresponding slideways (or slide rails, slide bars), so as to realize independent and automatic movement of the red light irradiation component in one or more directions based on the positioning information determined by the positioning component. Figure 3-Figure 8 The red light irradiation device according to the embodiment of the utility model is described in detail.

[0043] In combination with the above description, it can be known that the embodiment of the utility model can automatically align the red light irradiation source with the ocular surface (such as pupil, iris) by adding a positioning component to the red light irradiation device for myopia therapy, thereby effectively improving the utilization rate of red light irradiation of the fundus and significantly improving the myopia therapy effect. Specifically, the positioning component collects the ocular surface image to determine the positioning information, and the mobile component automatically moves the red light irradiation component in one or more moving directions based on the determined positioning information. Among them, the aforementioned mobile component may include at least one mobile platform, such as a first, second and third mobile platform. By arranging the red light irradiation component on the first mobile platform and slidingly connecting the first, second and third mobile platforms, the red light irradiation component is moved along the corresponding moving directions to realize red light irradiation of the fundus. Further, the aforementioned at least one mobile platform operates based on the positioning information obtained in real time by the positioning component, and drives the first mobile platform, the second mobile platform and the third mobile platform to independently and automatically move the red light irradiation component in one or more directions in the XYZ direction via the corresponding transmission mechanism (such as the first, second and third transmission mechanism) to irradiate the fundus with red light. Based on this, not only can the irradiation efficiency be greatly improved, but the red light irradiation component can also be accurately and timely adjusted to the target position to ensure a good irradiation effect.

[0044] Figure 3 is an exemplary schematic diagram showing a red light irradiation component according to an embodiment of the present utility model. Figure 3As shown in the figure, the red light irradiation component 201 of the embodiment of the utility model may include a red light source 301 and a front lens group 302. As mentioned above, the red light source 301 is used to provide red light to irradiate the surface of the eyeball (i.e., the ocular surface) or the fundus, and the front lens group 302 may include one or more lenses (e.g., convex lenses and / or concave lenses) or plane mirrors to achieve red light irradiation of the fundus. Further, a positioning component is arranged around the red light irradiation component 201, and the positioning component may include at least two cameras and an image analysis module (not shown in the figure). For example, two cameras 303 are exemplarily shown in the figure, which are respectively arranged on both sides of the red light irradiation component 201, so as to collect ocular surface images from different angles. In the implementation scenario, the above two cameras 303 can each collect an ocular surface image. Based on the two collected ocular surface images, the two ocular surface images can be analyzed by the image analysis module to obtain ocular surface features (e.g., the position, direction, shape and / or size of the pupil or iris), and then determine the positioning information according to the ocular surface features. In some embodiments, the aforementioned image analysis module may be, for example, a neural network model or other computer vision model. Specifically, the position difference of the same ocular surface feature on two ocular surface images may be detected by, for example, a neural network model or other computer vision model, and then the spatial position of the ocular surface feature may be calculated to determine the positioning information according to the spatial position of the ocular surface feature. In an embodiment of the utility model, the red light irradiation component is automatically moved in at least one moving direction based on the determined positioning information via the moving component, so that the red light irradiation component is aimed at the eyeball 102 and is in the target position or ideal state, thereby achieving a good irradiation effect.

[0045] Figure 4 is an exemplary schematic diagram showing a red light irradiation device according to an embodiment of the present utility model. Figure 4 As shown in the figure, the red light irradiation device may include a moving component, and the moving component may include at least one moving platform. For example, three moving platforms are shown in the figure, namely, a first moving platform 401, a second moving platform 402, and a third moving platform 403. Further, the red light irradiation device also includes a red light irradiation component, and the red light irradiation component may include a red light source 301 and a front lens group 302 (that is, the above-mentioned Figures 1a-1f). As mentioned above, the aforementioned red light irradiation assembly can be arranged on the first mobile platform 401, the first mobile platform 401 can be arranged on the second mobile platform 402, and the positioning assembly 202 is arranged on both sides of the red light irradiation assembly. As an example, the first mobile platform 401 can be driven by the first transmission mechanism to move in the vertical direction along the plane where the second mobile platform 402 is located, so as to move the red light irradiation assembly in the first direction (for example, the Z direction). Further, the above-mentioned second mobile platform 402 can be arranged above the third mobile platform 403 via the second transmission assembly, and the second mobile platform 402 can be driven by the second transmission mechanism to move in a direction perpendicular to the third mobile platform 403, so as to move the red light irradiation assembly in the second direction (for example, the Y direction). In addition, the third mobile platform 403 can also be driven by the third transmission mechanism to move in the horizontal direction along the base, so as to move the red light irradiation assembly in the third direction (for example, the X direction).

[0046] Based on the above description, it can be known that, based on the positioning information determined by the positioning component 202, the red light irradiation component can be moved in one or more directions, such as the XYZ directions, to irradiate the fundus of the eyeball 102 with red light. It can be understood that Figure 4 : is a diagram showing the red light irradiation to the fundus of a single eye. In some embodiments, the red light irradiation component can be moved in one or more directions based on the positioning information of both eyes to irradiate the fundus of both eyes with red light, for example Figure 5 shown.

[0047] Figure 5 FIG. 2 is another exemplary schematic diagram showing a red light irradiation device according to an embodiment of the present utility model. Figure 5 The irradiation of the fundus of both eyes is shown in the figure. In this scenario, the red light irradiation device of the embodiment of the utility model may include two groups of mobile components, two groups of red light irradiation components and two groups of positioning components 202. Among them, each of the aforementioned groups of mobile components may include at least one mobile platform. For example, three mobile platforms are exemplarily shown in the figure, namely, a first mobile platform 401, a second mobile platform 402 and a third mobile platform 403. Each of the aforementioned groups of red light irradiation components may include a red light source 301 and a front lens group 302. Similar to the irradiation of the fundus of a single eye, each of the aforementioned groups of red light irradiation components is correspondingly arranged on the first mobile platform 401 in each group of mobile components, and the first mobile platform 401 is arranged on the second mobile platform 402 in each mobile component, and a group of positioning components 202 is arranged on both sides of each group of red light irradiation components. Furthermore, the second mobile platform 402 is arranged above the third mobile platform 403 in each mobile component based on its own third transmission mechanism (not shown in the figure). In some embodiments, the two groups of mobile components can be arranged together on a base (for example Figure 6 shown).

[0048] In the implementation scenario, based on the positioning information determined by each group of positioning components 202, each group of moving components can move the red light irradiation component in one or more directions in the XYZ direction to irradiate the fundus of both eyes with red light. Compared with the irradiation of the fundus of a single eye, the positioning of the fundus of both eyes not only considers the relative position, distance, direction change and pupil size between the single eye and the red light irradiation component, but also considers the pupil distance between the two eyes to ensure the red light irradiation effect. For more details about each movement direction, please refer to the above Figure 4 The utility model will not be repeated here.

[0049] Figure 6 is a schematic diagram showing an exemplary structure of a red light irradiation device for binocular myopia therapy according to an embodiment of the utility model. It should be understood that, Figure 6 The red light irradiation device shown is the above Figure 5 A specific embodiment of the red light irradiation device in the embodiment of Figure 5 The description also applies to Figure 6 .

[0050] like Figure 6 As shown in the figure, the red light irradiation device of the embodiment of the utility model may include two groups of mobile components, two groups of red light irradiation components and two groups of positioning modules. Each group of mobile components may include at least one mobile platform. For example, three mobile platforms are shown in the figure, namely, a first mobile platform 401, a second mobile platform 402 and a third mobile platform 403, and the red light irradiation components may include a red light source 301, a front lens group 302 and a rear lens group 601. The aforementioned positioning modules may each include two cameras 602 (i.e., the aforementioned Figure 3 The two cameras 303 shown in the figure are arranged on both sides of each group of red light irradiation components to collect eye surface images and determine positioning information. As mentioned above, each group of red light irradiation components can be arranged on the first mobile platform 401, the first mobile platform 401 is arranged on the second mobile platform 402, and is driven to move on the second mobile platform 402 via a first transmission mechanism. In one embodiment, the first transmission mechanism may include a first transmission device (such as an electromagnetic or motor, etc., not shown in the figure) and a first transmission path (such as a slideway) 603, and the first transmission path 603 extends in the vertical direction of the plane where the second mobile platform 402 is located. In the implementation scenario, the aforementioned first transmission device drives the first mobile platform 401 to move on the first transmission path 603 to move the red light irradiation component in a first direction (for example, the Z direction, as shown by arrow A).

[0051] like Figure 6It is further shown in the figure that the second mobile platform 402 of each group of mobile components is arranged on the third mobile platform 403 via a second transmission mechanism. In one embodiment, the second transmission mechanism may include a second transmission device (such as an electromagnetic or motor, etc., not shown in the figure) and a second transmission track (such as a slide bar) 604, and the second transmission track 604 is vertically arranged on the third mobile platform 403, and a top plate 605 may also be provided on the top of the second transmission track 604. In this scenario, the aforementioned second transmission device can drive the second mobile platform 402 to move on the second transmission track 604 to move the red light irradiation component in a second direction (such as the Y direction, as shown by the arrow B).

[0052] Further, the two groups of third mobile platforms 403 can be driven to move in the horizontal direction along the plane where the base 606 is located via the third transmission mechanism. In one embodiment, the third transmission mechanism may include a third transmission device (such as an electromagnetic or motor, etc., not shown in the figure) and a third transmission track (such as a slideway) 607, and the third transmission track 607 is arranged on the aforementioned base 606 and extends in the horizontal direction of the plane where the base 606 is located. In the implementation scenario, the aforementioned third transmission device drives the third mobile platform 403 to move on the third transmission track 607 to move the red light irradiation component in a third direction (such as the X direction, as shown by the arrow C).

[0053] It is important to understand that the above Figure 6 The arrangement of the first, second and third mobile platforms is only exemplary, and the movement of the first, second and third mobile platforms relative to the first, second and third directions is also only exemplary and not restrictive. Based on the different arrangements of the first, second and third mobile platforms, the corresponding movement directions may be different. For example, the second mobile platform may also be arranged to move along the third direction, and is not limited to the movement along the second direction in the embodiment of the utility model.

[0054] In one embodiment, the red light irradiation device of the utility model embodiment may also include a control circuit, which can be used to control the moving component to move the red light irradiation component in at least one direction based on the positioning information, so that the red light irradiation component can realize red light irradiation of the fundus.

Among them, each camera can be arranged around or on both sides of the red light irradiation component 201, and each camera is used to collect an eye surface image. Based on the collected eye surface image, it can be analyzed by an image analysis module (such as a neural network model) to obtain eye surface features (such as pupils), and then determine the positioning information. It should be understood that the specific position of the aforementioned camera in the red light irradiation component 201 and the angle relative to the red light irradiation component 201 can be set according to the actual scene, and the utility model does not limit this.

[0056] Based on the positioning information determined above, the control circuit 701 can be used to control the mobile component to move the red light irradiation component 201 in at least one direction based on the positioning information. In an implementation scenario, the control circuit 701 can be, for example, a microcontroller unit (MCU), and the control circuit 701 can include one or more groups.

Alternatively, multiple groups of control circuits can be used to control each rotating structure to control the movement of the red light irradiation component, and the utility model does not limit this.

[0057] Figure 8 FIG. 1 is an exemplary flowchart showing a red light irradiation method for myopia treatment according to an embodiment of the present invention. Figure 8As shown in, at step S802, an ocular surface image is collected, and positioning information is determined based on the ocular surface image. For example, in an implementation scenario, the ocular surface images can be collected from different angles by using at least two cameras, and then the ocular surface images at different angles can be analyzed using an image analysis module to obtain the ocular surface features, so as to determine the positioning information based on the ocular surface features. In one embodiment, the aforementioned image analysis module can be, for example, a neural network model or other computer vision models. The aforementioned ocular surface features can be, for example, the position, direction, shape and / or size of the pupil or iris. Based on the obtained positioning information, at step S804, based on the positioning information, the red light irradiation component is moved in at least one direction so that the red light irradiation component can realize red light irradiation of the fundus. In one embodiment, the red light irradiation component can be moved in at least one direction by a moving component. Among them, the moving component can include at least one moving platform, such as a first, second and third moving platform. Among them, the red light irradiation component can be arranged on the aforementioned first moving platform, and the first, second and third moving platforms are slidably connected to realize moving the red light irradiation component in one or more directions. Therefore, based on the aforementioned positioning information, the aforementioned mobile component can move the red light irradiation component in one or more directions so that the red light irradiation component can achieve red light irradiation of the fundus. Based on this, the red light irradiation component can be accurately and timely adjusted to the ideal position to ensure a good irradiation effect.
