Description

Technical Field

[0001] This utility model relates to the field of ophthalmic optical instrument technology, and in particular to a visual function adjustment training instrument and system. Background Technology

[0002] With the widespread use of electronic products such as computers, mobile phones, and tablets, they have become indispensable tools in people's lives, work, and studies. Related eye diseases are also on the rise. For example, prolonged use of electronic products can lead to visual function problems, including myopia, and various eye problems such as decreased vision, reduced contrast sensitivity (the ability to distinguish grayscale differences), and temporary imbalance of binocular vision caused by eye strain (or visual fatigue). Visual function problems not only seriously affect the efficiency of users' lives, studies, and work, but can also cause long-term harm to eye and mental health. For example, high myopia can lead to ocular degeneration, and in severe cases, blindness; long-term uncorrected visual fatigue can induce or aggravate dry eye syndrome, glaucoma, and macular degeneration; chronic visual fatigue can lead to tension headaches and even cervical spondylosis (due to compensating for vision problems with poor posture).

[0003] Accordingly, existing technologies provide various visual function adjustment / training products capable of preventing and controlling myopia and amblyopia, and relieving eye strain, including various eye masks, eye patches, eye therapy devices, visual phototherapy devices, and eye physiotherapy equipment. Among these, visual phototherapy devices utilize artificial light sources to prevent and treat various visual function problems. By irradiating the eye (mainly the fundus) with light, they target different tissues of the eyeball to relieve eye strain and prevent and control myopia and amblyopia. Specifically, the irradiation light used in visual phototherapy devices includes various colorless or colored light sources such as lasers, visible red light, far-infrared light, red-green divergent light, and violet light. For example, Chinese patent ZL202021337384.3 discloses a high-red light structure for relieving myopia fatigue. This high-red light structure includes a mounting plate with multiple semiconductor lasers disposed on the same surface. Each semiconductor laser outputs visible high-red light with a wavelength of 635nm-645nm and a power of 0.285mW-0.6mW. This solution can generate visible high-red light to relieve myopia fatigue while achieving a low-power output, further stimulating structures such as the retina and choroid, increasing blood circulation in the choroid, promoting dopamine secretion, and effectively controlling axial elongation, thereby relieving myopia fatigue. For example, Chinese patent application CN202180063281.3 discloses a choroid thinning suppression device, which has a light source emitting violet light with wavelengths in the range of 360nm to 400nm, and irradiates the violet light to suppress choroid thinning. This device may also have a control mechanism to control the irradiance and irradiation time of the violet light, and is applicable to eye diseases selected from those based on insufficient or reduced blood flow, such as age-related macular degeneration, glaucoma, diabetic retinopathy, macular edema, eye fatigue, retinal vascular occlusion, triangle syndrome, central serous chorioretinopathy, retinitis pigmentosa, presbyopia, and cataracts, and is expected to be used for their prevention or treatment. Considering the home-use and portability of phototherapy devices, existing technologies also provide various portable visual phototherapy devices. For example, Chinese patent ZL201910879955.1 discloses a myopia prevention and control device based on a mobile terminal. The myopia prevention and control device includes a connector, a control module, and a light-emitting module. The red light or near-infrared light emitted by the light-emitting device directly irradiates the retina and choroid through the pupil. The low-intensity red light and near-infrared light can effectively and safely exert their photochemical effects, improve the metabolic rate and blood circulation of the retina and choroid, thereby playing a role in preventing myopia and slowing down or stopping the progression of myopia. The above-mentioned device is compatible with various mobile terminals, is small in size and portable, and realizes the function of eye protection and myopia prevention and control while using a mobile terminal.For example, Chinese patent application CN202010542370.3 discloses a near-infrared light fundus therapy device, including a head-mounted main body and a controller. The head-mounted main body is equipped with a near-infrared light source electrically connected to the controller. The near-infrared light source is used to irradiate the fundus of the user being tested. The near-infrared light source has multiple preset light output powers. The controller is used to control the near-infrared light source to select the corresponding preset light output power to adapt to the fundus disease condition of the user being tested.

[0004] However, existing visual phototherapy devices can usually only perform light adjustment training, have limited functions, and have fixed modes, resulting in limited visual adjustment and training effects. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a visual function adjustment training device and system. The visual function adjustment training device provided by this invention includes a display panel and a light stimulation unit. The front of the display panel includes a display for outputting visual stimulation information. Visual stimulation can promote the enhanced development of cells in the brain's visual center and improve vision. The light stimulation unit is used to radiate light of a preset wavelength to illuminate the user's eyes, such as visible red light and infrared light, which irradiate the retina and choroid through the pupil, promoting blood flow and metabolism in the retina and choroid. Thus, the synergistic effect of visual stimulation information and light illumination improves the adjustment and training effect of visual function.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A visual function accommodation training device includes a display panel and a light stimulation unit.

[0008] The front of the display panel includes a display for outputting visual stimulus information;

[0009] The light stimulation unit includes an illumination area located on the outer periphery of the front of the display panel. The illumination area is equipped with light-emitting elements to radiate light of a preset wavelength for the user to see, thus illuminating the user's eyes.

[0010] Furthermore, it also includes a base, in which a controller is installed. The controller is electrically connected to the display panel and the photostimulation unit to control their operation. Each electrical component is connected to a power source via wires. Operation buttons are provided on the base corresponding to the controller for user operation.

[0011] The display panel is fixedly mounted on the base; or, the display panel is mounted on the base via a movable connector, allowing the display panel to be flipped or moved in a plane relative to the base.

[0014] The display panel and the photostimulation unit have an idle state and an operating state.

[0015] Initially, the display panel and the light stimulation unit are idle and not working.

[0016] When the set time arrives, the display panel and the light stimulation unit are triggered to switch from the idle state to the working state. In the working state, the light-emitting element of the light stimulation unit radiates light, and the display outputs visual stimulation information.

[0017] When the set working time is reached, the display panel and the light stimulation unit are triggered to switch from the working state to the idle state and stop working.

[0018] Furthermore, in the working state, the light-emitting element of the light-stimulating part operates in one of the following ways:

[0019] Method 1: The light-emitting component emits light at a constant brightness;

[0020] Method 2: The light-emitting component adjusts the brightness of the light according to a preset time cycle, so that the brightness presents an alternating dynamic change or a gradual dynamic change. The dynamic change of brightness triggers the pupil reflex and trains the iris muscle's regulatory ability.

[0021] Furthermore, the operation buttons include a mode selection button, which includes a display mode button and a light stimulation part illumination mode button;

[0022] The display mode button is used by the user to set the mode in which the display outputs visual stimulus information.

[0023] The light emission mode button of the light stimulation part is used for the user to set the light emission mode of each light emission element of the light stimulation part; when the light emission elements in the light stimulation part adopt the same light emission mode, an isotropic uniform illumination area is formed; when the light emission elements in the light stimulation part adopt different light emission modes, an anisotropic non-uniform illumination area is formed.

[0024] Furthermore, the light-emitting element of the light-stimulating part is a red light source, forming a red light illumination area outside the display;

[0025] The red light source is a light-emitting diode or a laser, which can radiate visible red light and / or infrared light. The visible red light and / or infrared light irradiate the retina and choroid through the pupil, promoting blood flow and metabolism in the retina and choroid.

[0026] Furthermore, the light stimulation section includes a texture pattern composed of multiple illuminated color blocks. The visual elements of the light stimulation section are constructed by forming the texture pattern in the light stimulation section, thereby increasing the spatial frequency of the light stimulation section.

[0027] Furthermore, the photostimulation unit is provided with multiple different texture patterns, each texture pattern including multiple light lamp color blocks, and the size, shape and / or arrangement of the light lamp color blocks in different texture patterns are different;

[0028] By forming multiple texture patterns in the light stimulation area, the visual elements contained in the unit length space of the light stimulation area are increased, so as to form a high spatial frequency stimulus in the light stimulation area.

[0029] Furthermore, the visual stimulus information is a visual target presented on the display, and the visual target is a grating, Gabor stimulus, face, number, natural stimulus, picture, dot and / or graphic;

[0030] The display is a CRT display, a liquid crystal display, a plasma display, an electroluminescent display, or an organic light-emitting display.

[0031] Furthermore, the light stimulation unit also includes a second illumination area located on the back of the display panel, in which light-emitting elements are arranged to radiate light of a preset wavelength for the user to see, thus illuminating the user's eyes;

[0032] The light-emitting elements of the second illumination area are arranged across the entire back of the display panel; or, depending on the position of the illumination area on the front of the display panel, the light-emitting elements of the second illumination area are arranged on the back of the display panel, and no display is provided in the second illumination area.

[0033] This invention also provides a visual function adjustment training system, the system comprising a visual function adjustment training device and a user terminal connected in communication.

[0034] The visual function adjustment training device is the aforementioned visual function adjustment training instrument, used for relieving visual fatigue, training visual function, or preventing myopia.

[0035] The user terminal acts as a host computer, used to communicate and interact with the visual function adjustment training instrument, control the operation of the visual function adjustment training instrument, and receive feedback data from the visual function adjustment training instrument.

[0036] Compared with the prior art, this utility model, by adopting the above technical solution, has the following advantages and positive effects: The visual function adjustment training device provided by this utility model includes a display panel and a light stimulation unit. The front of the display panel includes a display for outputting visual stimulation information. Visual stimulation can promote the enhanced development of brain visual center cells and improve vision. The light stimulation unit is used to radiate light of a preset wavelength to illuminate the user's eyes. For example, visible red light and infrared light irradiate the retina and choroid through the pupil, which can promote blood flow and metabolism in the retina and choroid. Thus, the adjustment and training effect of visual function is improved through the synergistic effect of visual stimulation information and light illumination. Attached Figure Description

[0050] The visual function adjustment training device and system disclosed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated; they can be combined with each other to achieve better technical effects. In the accompanying drawings of the following embodiments, the same reference numerals appearing in each drawing represent the same features or components, which can be applied to different embodiments. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0051] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of the utility model. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the utility model, should fall within the scope of the technical content disclosed in the utility model. The scope of the preferred embodiments of this utility model includes other implementations, wherein functions may be performed not in the order stated or discussed, including substantially simultaneously or in reverse order, according to the functions involved. This should be understood by those skilled in the art to which the embodiments of this utility model pertain.

[0052] Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0053] In the description of the embodiments of this application, " / " means "or", and "and / or" is used to describe the relationship between related objects, indicating that there can be three relationships. For example, "A and / or B" means: A and B exist alone, B exists alone, and A and B exist simultaneously. In the description of the embodiments of this application, "multiple" refers to two or more.

[0054] Explanation of technical terms

[0055] Spatial frequency refers to the frequency of change in image detail per unit visual angle, usually measured in cycles per degree (cpd, cycles per degree). This metric refers to the distribution of the number of recurring patterns in a visual scene, such as the repetition of visual elements like lines, edges, or grids. Existing research shows that the visual cortex of the brain has a high contrast sensitivity to spatial frequency; the higher the spatial frequency, the more it stimulates the central cells of the visual cortex, enhancing their activity. The level of spatial frequency is closely related to visual function. High spatial frequency information contains small, detailed information, such as fine lines, fine textures, or small font text, which are typically used to depict the finer parts of an image. According to retinal imaging quality theory, high spatial frequencies (such as fine textures, dense stripes, or grids) require precise eye focusing, which can stimulate the retina to release dopamine, thus promoting visual function development. On the other hand, high spatial frequency information is usually accompanied by high contrast, which can enhance the retina's sensitivity to defocused signals, thereby regulating eye growth. In contrast to high spatial frequency information is low spatial frequency information, which contains larger, less detailed information, such as large shadows, outlines, or broad areas of color. This information is crucial for obtaining the overall layout and dynamic changes of a scene, such as identifying the basic shape and orientation of objects, or maintaining environmental consistency in light changes. Example

[0056] See Figure 1 As shown, this utility model provides a visual function adjustment training device 100, which includes at least a display panel 110 and a light stimulation unit.

[0057] The display panel 110 and the photostimulation unit 120 are connected to an associated controller, which operates the display panel and the photostimulation unit, preferably a microcontroller. In one embodiment, the controller is disposed on the display panel and electrically connected to the display and the photostimulation unit (in this case, the visual function adjustment training device may include the aforementioned controller), thereby controlling the operation of the display panel and the photostimulation unit. In another embodiment, the controller is not disposed on the display panel, but is disposed independently relative to the display panel. In this case, the controller can be electrically connected to the display and the photostimulation unit via a transmission line and control the operation of the display panel and the photostimulation unit.

[0058] The front of the display panel 110 includes a display 111 for outputting visual stimulus information.

[0059] The display 111 can specifically be a CRT (cathode ray tube display), a liquid crystal display (LCD), a light-emitting diode display (LED), an organic light-emitting diode display (OLED), a plasma display, or an electroluminescent display.

[0060] The visual stimulus information specifically refers to visual targets presented on the display, which can be gratings, Gabor stimuli, faces, numbers, natural stimuli, pictures, dots, and / or graphics. Optionally, the attributes of the visual targets can be dynamically adjusted to achieve visual function regulation or training. The attributes include, but are not limited to, the spatial frequency, physical intensity, contrast, shape, color, number, orientation, direction of movement, and / or size of the visual targets.

[0061] Preferably, the display can output high spatial frequency visual stimulus information (such as images containing fine textures, dense stripes, or grids) and low spatial frequency visual stimulus information (such as images containing large shadows, outlines, and few details) for visual function adjustment and training.

[0062] As an example, and not a limitation, the display 111 can show an image containing black and white stripes (visual targets), allowing the user's eyes to be stimulated by different spatial frequencies and by contrasting gratings from various angles. Furthermore, a series of square wave stripes (as visual targets) with different spatial frequencies and high contrast sensitivity can be rotated to form a dynamic image, stimulating the visual cells in the fovea of ​​the user's eye from different angles. On the one hand, the stripes, as a stimulus source, can train most cone cells; on the other hand, the rotation of the stripes allows the visual cells to receive stripe stimulation of different spatial frequencies from various angles, thereby achieving a better conditioning training effect. Considering that excessive visual stimulation may cause eye fatigue, the visual function conditioning training device also includes a timer to control the duration of visual stimulation information output by the display. When the set time is up, the display stops displaying the visual stimulation information, and the screen can then turn off and enter a black screen state. The timer function of the display is prior art and will not be described in detail here.

[0063] The light stimulation unit includes an illumination area 112 located on the outer periphery of the front of the display panel. Light-emitting elements are arranged in the illumination area 112 to radiate light of a preset wavelength for the user's eyes. Preferably, multiple light-emitting elements are arranged in rows and columns in the illumination area 112 to form a light-emitting element array.

[0064] Depending on the needs of adjustment and training, the light-emitting element of the photostimulation unit can be any colorless (white) or colored source, such as radiating visible red light, far-infrared light, red-green diffused light, or violet light. In this embodiment, preferably, the light-emitting element of the photostimulation unit is a red light source, thus forming a red light illumination area outside the display.

[0065] The red light source is a light-emitting diode or a laser, which can radiate visible red light and / or infrared light. The visible red light and / or infrared light irradiate the retina and choroid through the pupil, promoting blood flow and metabolism in the retina and choroid.

[0066] Visible red light has a wavelength range of 620–750 nm, is visible to the human eye, and has low energy due to its long wavelength; near-infrared light has a wavelength range of 750–1400 nm, is invisible, and has stronger penetrating power; mid / far-infrared light has a wavelength range >1400 nm and a strong thermal effect. This embodiment mainly utilizes low-intensity visible red light and near-infrared light for illumination. More preferably, the wavelength range of the light emitted by the light-emitting element is 630-1000 nm, and the optical power of the light source is preferably 0.37–1.20 mW, which is currently a commonly used safe and effective range in clinical practice. In specific operation, the power can be set in conjunction with parameters such as the angle of attack to ensure safety, which is existing technology and will not be elaborated here.

[0067] Preferably, the photostimulation section includes a texture pattern composed of multiple illuminated color blocks. Each illuminated color block may include one or more light-emitting elements. By forming the texture pattern in the photostimulation section, visual elements (such as lines, edges, or grids) of the photostimulation section are constructed to increase the spatial frequency of the photostimulation section. Taking red light as an example, multiple red light color blocks are formed by controlling whether the light-emitting elements in the illuminated area are lit or not. The multiple color blocks are regularly or irregularly distributed in the photostimulation section to form regular or irregular textures.

[0068] As an example, and not a limitation, let's consider the formation of alternating bright and dark stripes using an array of light-emitting elements. For instance, one or more columns of light-emitting elements can be controlled to illuminate (forming a bright stripe), while adjacent columns or more light-emitting elements remain off (forming a dark stripe), and so on. By controlling the light-emitting elements in the array to emit light according to this rule, regular, alternating bright and dark stripes with contrast can be formed. In this way, visual stimulation information (bright and dark stripes) is applied to the eyes while simultaneously illuminating them, improving the accommodation and training effects of visual function.

[0069] Considering the control of the light-emitting elements in the photostimulation section, the front of the display panel 110 may also be provided with a light-emitting area control button 1121 for controlling the operation of the light-emitting elements in the illumination area 112. Depending on the orientation of the light-emitting elements in the illumination area 112, there may be multiple light-emitting area control buttons 1121; this is merely an example and not a limitation. Figure 1 The example illustrates a scenario with two illumination zone control buttons 1121, corresponding to the on / off control of the light-emitting elements in the left and right sub-areas of the illumination zone, respectively.

[0070] Furthermore, when the illumination area 112 includes illumination color blocks, the front side of the display panel 110 may also include color block control buttons 1122 to adjust the size of the illumination color blocks, as an example and not a limitation. Figure 1 The example demonstrates setting three color block sizes for lighting color blocks, including large color block mode, medium color block mode, and small color block mode. Different color block modes correspond to different texture sizes. Compared to the large color block mode, the texture pattern in the medium color block mode contains more textures and has a higher spatial frequency. Compared to the medium color block mode, the texture pattern in the small color block mode contains even more textures and has the highest spatial frequency. At this time, there are three color block control buttons 1122. Users can select the texture refinement by touching the color block control buttons 1122. Figure 1 The example shows a texture pattern using a medium color block pattern. The texture pattern is a grid composed of multiple squares, each square being a color block, and each color block can include four light-emitting elements.

[0071] For example, this is meant as an example rather than a limitation. Figure 2 The example demonstrates a texture pattern using a small color block pattern. The texture pattern consists of multiple squares, with each square representing a color block, and each color block includes one light-emitting element. It should be noted that the outline shape of the color block is not limited to a grid; it can also be vertical stripes, horizontal stripes, diagonal stripes, L-shaped patterns, or zigzag textures, as long as they can form a texture on the outer perimeter of the display panel.

[0072] In this embodiment, the visual function adjustment training device 100 preferably adopts a seated structure. In this case, the visual function adjustment training device 100 also includes a base 120. See [link to documentation]. Figure 2 As shown, a controller may be installed in the base 120. The controller is electrically connected to the display panel and the photostimulation unit to control their operation. Each electrical component is connected to a power source via wires. The base 120 is equipped with operation buttons corresponding to the controller for user operation. For example, these operation buttons include, but are not limited to, a power switch button, a reset button, a switch button, and a confirm / cancel button. Optionally, the base may also be equipped with indicator lights, fault indicator lights, etc., to allow users to intuitively understand the working status of each component of the instrument.

[0073] The power source can be a built-in power source, in which case a battery can be installed in the base as a built-in power source; or it can be an external power source, in which case a power interface or power cord can be provided on the base to connect to an external power source—such as AC power. Preferably, the base is equipped with a rechargeable battery as a built-in power source, and the base is also equipped with a power interface, which can be connected to an external power source through a wire to supply power to the electrical components in the visual function adjustment training device, and / or to charge the rechargeable battery.

[0074] In one embodiment of this invention, the display panel 110 is fixedly mounted on the base 120. (See attached image) Figure 2 As shown.

[0075] In a specific implementation, the base 120 may include a base plate 121 for placing on a bearing surface, the base plate 121 is fixed with a support frame 122, and the display panel 110 is mounted on the base plate through the support frame 122.

[0076] In another embodiment of this invention, the display panel 110 is mounted on the base 120 via a movable connector, allowing the display panel 110 to be flipped relative to the base to adjust its angle, or to move in a plane to adjust its height and / or left / right position relative to the base. Specifically, the flipping movement can be achieved via a hinge axis, and the plane movement can be achieved via a track and a linear drive motor (including X-axis and Y-axis movement). These are existing flipping and plane movement mechanisms and are therefore considered prior art, and will not be elaborated upon further here.

[0077] In this embodiment, the operation buttons on the base 120 are preferably located on the base plate 121. The operation buttons may specifically include a control button 123 and a mode selection button 124.

[0078] The control button 123 may include an instrument power switch button, an illumination area control button, and a color block control button (at this time, the illumination area control button and the color block control button may not be set on the display panel).

[0079] The reminder trigger button 124 is used by the user to set the time for triggering the operation of the display panel and the light stimulation unit. The time includes the working cycle, start / end time and duration of the operation of the display panel and the light stimulation unit.

[0080] The display panel and the photostimulation unit have an idle state and an operating state.

[0081] Initially, the display panel and the light stimulation unit are in an idle state and do not work.

[0082] When the set time arrives, the display panel and the light stimulation unit are triggered to switch from the idle state to the working state (active state). In the working state, the light-emitting element of the light stimulation unit radiates light, and the display outputs visual stimulation information.

[0083] When the set working time is reached, the display panel and the light stimulation unit are triggered to switch from the working state to the idle state and stop working.

[0084] As a typical example, in this embodiment, the reminder trigger button 124 may include three adjustment buttons: a first adjustment button, a second adjustment button, and a third adjustment button.

[0085] The first adjustment button is used for the user to set the working cycle. For example, the first adjustment button may include three levels: 15 minutes, 30 minutes and 45 minutes, which respectively represent a working cycle of 15 minutes (the display panel and the light stimulation unit are activated once every 15 minutes), a working cycle of 30 minutes (the display panel and the light stimulation unit are activated once every 30 minutes), and a working cycle of 45 minutes (the display panel and the light stimulation unit are activated once every 45 minutes).

[0086] The second adjustment button allows the user to set the start / end time of the work – for example, the start / end time can be set to begin work at 9:00:00 AM (9:00:00) every day and end work at 6:00:00 PM (6:00:00) every afternoon (end time). At this time, with the instrument powered on (power switch on), the display panel and the light stimulation unit can enter working mode at exactly 9:00:00 AM, with the display panel outputting visual stimulation information and the light-emitting element of the light stimulation unit emitting light.

[0087] The third adjustment button is used to set the working duration of each operation (i.e., the working duration of each work cycle) – for example, the working duration can be set from 30 seconds to 300 seconds. Taking 30 seconds as an example, the display panel and the light stimulation unit work for 30 seconds each time, then switch to idle mode after 10 seconds of operation, stopping work and waiting for the next work cycle. For example, if the display panel and the light stimulation unit enter the working state at 9:00:00, they will exit the working state and enter the idle state at 9:00:10. At 9:30:00 (the work cycle is 30 minutes), the display panel and the light stimulation unit enter the working state again, and then exit the working state and enter the idle state at 9:30:10, thus repeating this cycle until 18:00:00, at which point the cycle terminates.

[0088] Preferably, in the operating state, the light-emitting element of the photostimulation unit operates in one of the following ways: Method 1: The light-emitting element emits light at a constant brightness. Method 2: The light-emitting element adjusts the brightness of the emitted light according to a preset time period, so that the brightness exhibits alternating high and low dynamic changes or gradual dynamic changes. These dynamic changes in brightness trigger the pupillary reflex, training the regulatory ability of the iris muscles (pupil sphincter and dilator muscles).

[0089] It should be noted that, in order to reduce visual fatigue caused by frequent dynamic changes in brightness, the frequency of dynamic changes in brightness should be controlled. Taking alternating high and low brightness as an example, the preferred cycle is 5 to 30 seconds. Taking a 30-second working time as an example, a cycle of 5 to 10 seconds can be selected, thereby controlling the light-emitting element to slowly alternate between high and low brightness.

[0090] In a preferred embodiment of this invention, the operation buttons on the base may further include mode selection buttons, which may specifically include a display mode button and a light stimulation part light emission mode button.

[0091] The display mode button is used by the user to set the mode in which the display outputs visual stimulus information. This is an example, not a limitation, and may include static mode and dynamic mode.

[0092] The light emission mode button of the light stimulation part is used to allow the user to set the light emission mode of each light-emitting component of the light stimulation part. As an example and not a limitation, it may include indoor mode, outdoor mode, sunrise and sunset mode, etc.

[0093] When all the light-emitting elements in the photostimulation section adopt the same light emission mode, an isotropic uniform illumination area can be formed, that is, a uniform illumination effect is formed; when the light-emitting elements in the photostimulation section adopt different light emission modes, an anisotropic non-uniform illumination area is formed, that is, a non-uniform illumination effect is formed.

[0094] In another embodiment of this invention, the photostimulation unit may also be provided with multiple different texture patterns (i.e., multiple texture patterns are formed in the illumination area), each texture pattern including multiple light lamp color blocks, and the size, shape, and / or arrangement of the light lamp color blocks in different texture patterns are different. In this way, by forming multiple texture patterns in the photostimulation unit, the visual elements contained in a unit length space of the photostimulation unit are increased, so as to form a high spatial frequency stimulus in the photostimulation unit.

[0095] See Figure 4 As shown, this example illustrates the scenario where different texture patterns are constructed in the left and right sub-regions of the illuminated area. In this case, two texture patterns are formed in the light-stimulated area, increasing the visual elements contained in a unit length of space within the light-stimulated area. Furthermore, more color blocks of different sizes, shapes, and arrangements can be used to construct more refined textures, thereby increasing the visual elements contained in a unit length of space within the light-stimulated area and improving visual function accommodation and training effects.

[0096] See Figure 5 As shown, an example is given of visual function modulation and training by outputting high spatial frequency visual stimuli information containing dense stripes through a display.

[0097] The display panel also has a back panel 113, which can be a standard back panel, see [link to documentation]. Figure 6 As shown.

[0098] Preferably, an illumination area is provided on the back of the display panel. In this case, the light stimulation unit may further include a second illumination area 114 located on the back 113 of the display panel, wherein an array of light-emitting elements is arranged in the second illumination area 114 to radiate light of a preset wavelength for the user to see, thereby illuminating the user's eyes.

[0099] The light-emitting element array of the second illumination area can be arranged across the entire back of the display panel. Alternatively, depending on the location of the illumination area on the front of the display panel, the light-emitting element array of the second illumination area can be arranged on the back of the display panel, but no display is installed in the second illumination area. See [reference needed]. Figure 7 As shown.

[0100] In this way, users can choose to adjust or train their visual functions through the front of the display panel or through the back of the display panel, depending on their actual adjustment or training needs.

[0101] Another embodiment of this utility model also provides a visual function adjustment training system.

[0102] See Figure 8 As shown, the system includes a visual function adjustment training device and a user terminal that are connected in communication.

[0103] The visual function adjustment training device is the aforementioned visual function adjustment training instrument, used for relieving visual fatigue, training visual function, or preventing myopia.

[0104] The user terminal acts as a host computer, used to communicate and interact with the visual function adjustment training instrument, control the operation of the visual function adjustment training instrument, and receive feedback data from the visual function adjustment training instrument.

[0105] The user terminal includes, but is not limited to, mobile phones, tablets, PDAs, or laptops. The communication method between the user terminal and the visual function adjustment training device can be wired or wireless (such as Wi-Fi or Bluetooth), and there are no restrictions on this.

[0106] Other technical features are described in the preceding embodiments and will not be repeated here.

[0107] In the above description, the disclosure of this utility model is not intended to limit itself to these aspects. Rather, within the scope of the target protection of this disclosure, the components can be selectively and operationally combined in any number. Furthermore, terms such as "comprising,"

[0108] The terms “encompassing” and “having” should be interpreted by default as inclusive or open-ended, rather than exclusive or closed, unless explicitly defined as such. All technical, scientific, or other terms shall be interpreted as understood by one of those skilled in the art, unless explicitly defined as such. Public terms found in dictionaries should not be interpreted in the context of the relevant technical documentation in an overly idealistic or impractical manner, unless explicitly defined as such in this disclosure. Any modifications or alterations made by one of ordinary skill in the art based on the foregoing disclosure are within the scope of the claims.
