Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electronic device that applies light to the eye. Background Technology

[0002] Applying light to the eyes can achieve various visual rehabilitation purposes. For example, irradiating the center, periphery, and periocular area of ​​the fundus with red light of a specific wavelength can treat myopia, slow down and control the progression of myopia, relieve eye fatigue, and improve uncorrected visual acuity. Alternatively, guiding users to perform binocular fusion through light can promote the recovery of vision in amblyopic eyes.

[0003] In existing technologies, the light source forms a uniform circular light spot at a certain distance through optical conversion. This circular light spot covers the entire pupil, and the light entering the pupil is the effective light, which can be quantified as the light power entering the eye. Since the size of the human pupil varies, data shows that the pupil diameter is related to ambient light; as illuminance increases, the pupil diameter tends to decrease.

[0004] Under normal lighting conditions, the pupil diameter typically ranges from 2.5mm to 5mm. The human pupil has an involuntary adjustment function, constricting in bright light and dilating in dim light. In a dark room, the pupil diameter can reach 5mm-7mm, while under lighting conditions, it may decrease to less than 3mm. With a fixed light source output power, when the pupil diameter is 7mm, the light entering the eye is 7.8 times that when the diameter is 2.5mm. The light entering the eye's power is one of the most critical parameters for myopia and amblyopia treatment devices. Insufficient power leads to poor treatment results, while excessive power may cause discomfort or even burn the eye. Utility Model Content

[0007] An outer casing, the outer casing including a cavity;

[0008] Image sensor, the image sensor being used to acquire images of the user's eyes;

[0009] A light source, located within the cavity, wherein light emitted from the light source is guided and at least partially incident on the user's eyes;

[0010] A light-shielding component located on the light path of the light source, the light-shielding component including at least one light-shielding plate, the light-shielding component reducing the light power of the light source incident on the user's eye through the light-shielding plate when working;

[0011] The control unit is coupled to the image sensor, the light source, and the light-shielding component. The control unit is used to identify the eye state based on the eye image, control the light source and the light-shielding component to work simultaneously for a first preset time or the user's eye to reach a preset eye state; control the light-shielding component to turn off, and the light emitted from the light source to directly enter the user's eye for a second preset time.

[0012] Optionally, the light-shielding assembly includes a transmission mechanism and at least one light-shielding plate. When the light-shielding assembly is in operation, the transmission mechanism drives at least one of the light-shielding plates to move into the optical path of the light source.

[0013] Optionally, the transmission mechanism controls the movement of the light-shielding plate in a telescopic or rotary manner.

[0014] Optionally, the preset eye state includes reducing the pupil size to a preset size.

[0015] Optionally, it also includes a proximity sensor located on the side of the housing closer to the user when in use;

[0021] Optionally, the light source emits red light in the range of 630nm-700nm.

[0022] This invention provides an electronic device that uses light to treat the eye. An image sensor acquires an image of the user's eye, and a control unit identifies the user's eye state based on this image. If the control unit detects that the user's eye state has not reached a preset state, the device enters a treatment plan preparation stage, where the control unit controls the light source and light-shielding component to work simultaneously for a first preset time or until the user's eye reaches the preset state. When the control unit detects that the user's eye has reached the preset state, the device enters a treatment plan execution stage, where the control unit controls the light-shielding component to close, and the light emitted from the light source directly enters the user's eye for a second preset time, thus achieving eye treatment. This improves the device's safety when the user first uses it, while also guiding the user's eye state to reach the preset state more quickly, thereby enhancing the therapeutic effect of the electronic device.

[0029] Figure 1 This is a schematic diagram of the structure of an electronic device that allows light to act on the eye, as provided in an embodiment of the present invention. (Refer to...) Figure 1 The electronic device includes a housing 100, an image sensor 110, a light source 120, a light-shielding assembly 130, and a control unit 140. The housing 100 includes a cavity; the image sensor 110 is used to acquire images of the user's eyes; the light source 120 is located within the cavity, and the light emitted from the light source 120 is guided to at least partially enter the user's eyes; the light-shielding assembly 130 is located in the light path emitted from the light source 120, and includes at least one light-shielding plate, which reduces the light power of the light source 120 incident on the user's eyes during operation; the image sensor 110, the light source 120, and the light-shielding assembly 130 are all coupled to the control unit 140, which is used to identify the eye state based on the eye image, control the light source 120 and the light-shielding assembly 130 to work simultaneously for a first preset time or until the user's eyes reach a preset eye state; control the light-shielding assembly 130 to turn off, and the light emitted from the light source 120 to directly enter the user's eyes for a second preset time.

[0030] For example, the housing 100 includes a light source 120 for emitting light, at least a portion of which enters the user's eyes, enabling the image capture component 110 to capture an image of the user's eyes. The image sensor 110 is used to capture the user's eye image and identify the eye state based on the image. The eye image includes the user's left and right pupil sizes and interpupillary distance.

[0031] For example, the control unit 140 can identify the user's eye state based on the acquired eye image, and thereby control the state of the light source 120 and the light-shielding component 130. When the control unit 140 detects that the user's eye state has not reached a preset eye state, the control unit 140 controls the light source 120 and the light-shielding component 130 to work simultaneously for a first preset time or the user's eyes reach the preset eye state; when the control unit 140 detects that the user's eyes have reached the preset eye state, the control unit 140 controls the light-shielding component 130 to turn off, and the light emitted from the light source 120 directly enters the user's eyes for a second preset time.

[0032] For example, the first preset time is a pre-set duration for illuminating the user's eyes with the light source 120 under the cover of the light-shielding component 130, and the preset eye state includes the pupil size shrinking to a preset size. The second preset time is a pre-set duration for illuminating the user's eyes with the light source 120 turned off. The first and second preset times can be set according to actual needs, and this embodiment of the present invention does not impose specific limitations on them.

[0033] In one embodiment, when a user first comes into contact with the light emitted by the light source 120, the control unit 140 detects that the user's eyes have not reached the preset eye state. At this time, the control unit controls the light source 120 and the light-shielding component 130 to work simultaneously. After being partially blocked by the light-shielding component 130, the reduced power of the light shines on the user's eyes, allowing the user to gradually adapt to the light emitted by the light source 120 shining on their eyes, thus improving the safety of the electronic device. At the same time, the user's pupil size will relatively shrink, guiding the pupil to reach the preset eye state more quickly, thus improving the therapeutic effect of the electronic device. In specific implementations, the light transmittance of the light-shielding plate can be designed according to actual conditions, and this embodiment of the present invention does not impose any limitations on this.

[0034] It is understood that in this embodiment, the operation of the electronic device is divided into two treatment phases: a treatment plan preparation phase and a treatment plan execution phase. In the treatment plan preparation phase, the light source 120 is turned on for illumination, while a light-blocking component 130 is used to partially block the light, reducing its power. After the pupil has fully adapted, an eye image is acquired, and the eye state and pupil size are calculated using a recognition algorithm. Based on the pupil size and the set power level, the light output power is calculated, and then the treatment plan execution phase begins.

[0035] During the treatment process, the light-blocking component 130 is gradually deactivated so that it no longer blocks the light emitted from the light source 120, allowing the light source 120 to emit light at the set treatment power. Then, the eye condition and pupil size are monitored in real time during treatment, and abnormalities are addressed with appropriate strategies. For example, if an abnormal eye condition is detected, including but not limited to closed eyes, strabismus, or turning away, treatment is paused until the eye condition returns to normal, at which point treatment resumes.

[0036] It is important to note that, unlike existing technologies, this embodiment employs a preparation phase in the laser treatment process. During this phase, the light-shielding component 130 blocks part of the light emitted from the light source 120, reducing the light power irradiating the user's eyes. This allows the pupil to adapt effectively during the preparation phase. By using low-power irradiation during this preparation phase, the eye can adapt to the light, improving safety. Furthermore, under low-power light, the pupil constricts, becoming closer to the pupil state during the actual treatment, achieving a more stable state. It is crucial to understand that determining the pupil diameter is the most critical aspect of the entire treatment plan. If the image sensor 110 cannot accurately determine the true pupil diameter, it cannot correctly match the appropriate power for optimal treatment. Therefore, this preparation phase has two core functions: first, to allow the eye to adapt, improving safety; and second, to bring the pupil closer to the state required for treatment, resulting in more accurate light output, thus ensuring both safety and treatment effectiveness.

[0037] The electronic device provided in this embodiment of the invention uses an image sensor to acquire images of the user's eyes. A control unit identifies the user's eye state based on these images. When the control unit detects that the user's eye state has not reached a preset state, it enters a treatment plan preparation state, where the control unit controls the light source and light-shielding component to work simultaneously for a first preset time or until the user's eyes reach the preset state. When the control unit detects that the user's eyes have reached the preset state, it enters the treatment plan execution stage, where the control unit controls the light-shielding component to close, and the light emitted from the light source directly enters the user's eyes for a second preset time, thus achieving eye treatment. This improves the device's safety when the user first uses it, while also guiding the user's eye state to reach the preset state more quickly, thereby enhancing the therapeutic effect of the electronic device.

[0038] For example, continue to refer to Figure 1 The light-shielding assembly 130 includes a transmission mechanism 1301 and at least one light-shielding plate 1302. When the light-shielding assembly 130 is working, the transmission mechanism 1301 drives at least one light-shielding plate 1302 to move into the optical path of the light source 120. When the light-shielding assembly 130 is working, the light-shielding plate 1302 moves into the optical path of the light source 120, which can block part of the light emitted by the light source 120, reduce the power of the light emitted by the light source 120, make it easier for the eyes of first-time users to adapt, and improve the safety of electronic devices.

[0039] Exemplarily, the transmission mechanism 1301 controls the movement of the light-shielding plate 1302 in a telescopic or rotary manner. A spring can be provided between the transmission mechanism 1301 and the light-shielding plate 1302 to allow the transmission mechanism 1301 to control the movement of the light-shielding plate 1302 in a telescopic manner. A gear can also be provided between the transmission mechanism 1301 and the light-shielding plate 1302 to allow the transmission mechanism 1301 to control the movement of the light-shielding plate 1302 in a rotary manner. The connection method between the transmission mechanism 1301 and the light-shielding plate 1302 can be configured according to actual needs, and this embodiment of the present invention does not impose any limitations on this.

[0040] For example, continue to refer to Figure 1 The electronic device also includes a proximity sensor 150, which is positioned on the side of the housing 100 closest to the user when in use, to detect the user's position relative to the housing 100. The proximity sensor 150 is coupled to a control unit 140, which, upon receiving a trigger signal indicating a position response, controls the actions of the image sensor 110 and / or the light source 120. The position response includes two actions: the user approaching the electronic device and the user moving away from the electronic device. When the proximity sensor 150 detects the user approaching the electronic device, the image sensor 110 captures an image of the user's eyes, and the control unit 140, recognizing the user's eye state, controls the light source 120 to turn on. When the proximity sensor 150 detects the user moving away from the electronic device, the image sensor 110 and / or the light source 120 turn off or reduce the output power of the light source 120 to wait for the user to approach again, reducing power consumption. Alternatively, a time limit can be set; if the user does not return within a certain time limit, such as 10 minutes, the device automatically shuts down to ensure safety and prevent eye strain caused by misalignment.

[0041] For example, the cavity also includes two lens tubes 160; each of the two lens tubes 160 is provided with a light source 120.

[0042] For example, an image sensor 110 is provided in both lens barrels 160.

[0043] For example, the electronic device also includes a supplementary light 170, which is disposed within the housing 100. The light emitted by the supplementary light 170 at least partially enters the user's eyes. Because the electronic device may block light when close to the user's eyes, the area around the eyes may be relatively dark. The supplementary light 170 provides supplementary light when the image sensor 110 acquires images of the user's eyes, making the images captured by the image sensor 110 clearer and improving the control unit 140's ability to recognize the user's eye images.

[0044] For example, the electronic device also includes a power supply assembly 180 for powering the entire electronic device.

[0045] For example, light source 120 emits red light with a wavelength of 630nm-700nm. The red light with a wavelength of 630nm-700nm achieves the purpose of treating myopia, delaying and controlling the progression of myopia, relieving eye fatigue, and improving uncorrected visual acuity.

[0046] Figure 2 This is a schematic diagram of a phototherapy scheme provided in an embodiment of the present invention, for reference only. Figure 2 The treatment process includes a treatment plan preparation phase t1 and a treatment plan operation phase t2. In the treatment plan preparation phase t1, after the light-blocking component blocks part of the light emitted from the light source, the light power output by the light source to the user's eye is yA, which is lower than the set power of the light source. It should be noted that this power phase does not necessarily operate at a fixed low power value; it can also output power with a linear curve or an oscillating curve.

[0047] During the treatment protocol's execution phase t2, the light power output from the light source to the user's eye is yB. ​​At t2, the shading effect of the light-shielding component is adjusted according to the safety strategy. Figure 2 Assuming that the diameter of the human eye pupil does not change during the treatment process, the output power of the light source remains constant during the treatment process.

[0048] The following example uses the pupil size of 50 test subjects under different light intensities. A reference pupil size of 4mm was set. The test subjects were exposed to no light, light with a first power of 0.03mW (light blocked by the light shield 1302), and light with a second power of 0.2mW (light not blocked by the light shield 1302). The effectiveness of the solution provided by this invention was illustrated by measuring the pupil size of the test subjects. The test data are shown below:

[0049]

[0050]

[0051] The test data in the table above shows that under the first power light irradiation, the pupil size in the early stages is closer to the pupil size during the treatment phase, and there is a significant difference compared to the dark conditions. Under dark conditions, the average pupil size of the 50 test subjects was 5.9 mm; under the first power light irradiation, the average pupil size was 3.3 mm; and under the second power light irradiation, the average pupil size was 3.0 mm. For ease of calculation, assuming the pupil is a perfect circle, the average pupil area of ​​the 50 test subjects under dark conditions was 27.8 mm². 2 The average pupil area under the first power illumination condition was 8.8 mm. 2 The average pupil area under the second power illumination condition was 7.2 mm. 2If the pupil area under no-light conditions, i.e., the pupil size acquired before light exposure, is used as the input parameter for calculating the emitted light power of the light source 130 that is not blocked by the light shield 1302, the actual output light power is only 25.9% of the designed treatment power, significantly reducing the treatment effect. By adding the capture of eye image information under the first power light exposure condition of the light source 120 after being blocked by the light shield 1302, i.e., acquiring the user's eye image under the first power light exposure condition, and using it as the input parameter for the emitted light power of the light source 120 that is not blocked by the light shield 1302, the actual output light power reaches 81.8% of the designed treatment power, and the treatment effect is close to that. Then, fine-tuning is performed according to the adjustment strategy during the treatment process to ensure safety while achieving the best treatment effect. That is, there is a power increase phase in the treatment stage. In this phase, the pupil size can be continuously approached to the most realistic pupil size in the treatment stage, which speeds up the adjustment efficiency.

[0052] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
