[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] With the incidence of myopia rising year by year, and myopia trending towards younger ages and more severe cases, early onset of myopia in children significantly increases the incidence of high myopia, leading to blinding eye diseases such as retinal detachment, retinal atrophy, and macular hemorrhage, seriously endangering visual health. Therefore, how to control the development of myopia and reduce its incidence has always been a key social concern.

[0023] This invention is based on the high-resolution light theory and uses a diffused light source to achieve myopia control. The high-resolution light theory is introduced as follows:

[0024] 1. The classification of incoming light rays according to the high-resolution theory

[0025] The high-ambient-light theory divides the light entering the human eye into two categories: one category is light that participates in imaging, called imaging light; the other category does not participate in imaging, but only provides light perception, called ambient light.

[0026] 2. The theory of high-level illumination consists of the above three principles:

[0027] Principle 1: When the amount of light entering the eye that forms visual perception is constant, the lower the proportion of imaging light to the total light entering the eye and the higher the proportion of ambient light, the more beneficial it is for controlling the occurrence, development and axial elongation of myopia; conversely, the more beneficial it is for controlling the occurrence, development and axial elongation of myopia.

[0028] Principle 2: When the ratio of imaging light to ambient light is constant, the greater the total amount of light that forms visual perception, the better the visual effect, the clearer the image, and the more beneficial it is for controlling the occurrence, development, and axial elongation of myopia; conversely, the less beneficial it is.

[0029] Principle 3: The necessary condition for image formation is that the imaging light must be greater than the ambient light. When the imaging light is greater than the ambient light, the eye will form an image based on the visual image provided by the imaging light; otherwise, an image cannot be formed.

[0030] Please see Figure 1 Based on the above theoretical foundation, this embodiment provides a supplementary lighting device equipped with a diffused light source, including a crossbeam frame 1, with a left support 2 and a right support 3 respectively arranged on both sides of the crossbeam frame 1, and a nose bridge support 4 arranged on the lower side of the crossbeam frame 1. The left support 2 and the right support 3 are used to support the auricle, and the nose bridge support 4 is placed on the bridge of the nose, thereby positioning the crossbeam frame 1 close to the eyes.

[0031] The light-emitting module 5 is arranged on the cross beam frame 1, and the light-emitting module 5 can adjust the angle of the light source based on the eye distance of Asian children and the habit of wearing glasses.

[0032] Specifically, the wearer places the left support 2 and the right support 3 of the light supplement device on the auricles, places the bridge frame 4 on the nasal bridge, and sets up the light supplement device on the head position, and then the light-emitting module 5 emits light sources, which pass through the human eye refraction system and enter the corresponding pupil, and the light source emitted by the light-emitting module 5 deviates from the image point (the image point is the image point of other light sources entering the corresponding eye) when entering the corresponding eye, so that the light entering the eye can be increased while avoiding the participation of the light in imaging, that is, the environmental light is increased while the imaging light remains unchanged.

[0033] Specific introduction of the light-emitting module 5:

[0034] Please refer to Figure 1 and Figure 2 The light-emitting module 5 includes two groups of LED patch lights 51 arranged on the cross beam frame 1 and located on both sides of the bridge frame 4, and a light sensor 52 arranged on the outer side of the cross beam frame 1 and a control chip 53 arranged in the inner side of the cross beam frame 1, wherein the LED patch lights 51 and the light sensor 52 are electrically connected with the control chip 53.

[0035] The light source emitted by the light-emitting module 5 is mainly irradiated by the two groups of LED patch lights 51, and the light sensor 52 and the control chip 53 mainly control the light intensity of the LED patch lights 51. As the wearer moves around, the intensity of the external environmental light also changes, so the light intensity of the LED patch lights 51 needs to be adjusted to meet the appropriate proportion of the environmental light and the imaging light.

[0036] Specific operation: the external environmental light irradiates on the light sensor 52, and the light sensor 52 transmits the intensity of the light to the control chip 53 through the electrical signal, and the control chip 53 transmits the electrical signal to the LED patch lights 51, and adjusts the intensity of the LED patch lights 51 accordingly.

[0037] When the intensity of the external environmental light increases, the light sensor 52 transmits the sensing electrical signal to the control chip 53, and the control chip 53 controls the brightness of the two groups of LED patch lights 51 to increase; when the intensity of the external environmental light decreases, the light sensor 52 transmits the sensing electrical signal to the control chip 53, and the control chip 53 controls the brightness of the two groups of LED patch lights 51 to decrease, so as to automatically adjust the environmental light according to the intensity of the external environmental light.

[0038] The intensity of the external environmental light and the brightness of the LED patch lights (51) are roughly as follows:

[0039]

[0040] Please refer to Figure 1 , it should be noted that the specific location of each group of LED patch lights 51 is located on the side of the cross beam frame 1 close to the head, and the cross beam frame 1 is provided with a mounting groove 6 for placing the LED patch light 51, wherein the distance between the LED patch light 51 and the pupil in the height direction is 2cm-3cm, and the distance between the LED patch light 51 and the pupil in the horizontal direction is about 1.5cm-2cm.

[0041] And the selected light-emitting wavelength of the LED patch light 51 is 500nm to 900nm. Its light is warm white, and the illuminance is between 100LUX and 500LUX.

[0042] Please refer to Figure 1 and Figure 2 , wherein each group of LED patch lights 51 is composed of five patch lamp beads 511, and the wavelengths of the five patch lamp beads 511 arranged from the temporal side to the nasal side are 500nm, 600nm, 700nm, 800nm and 900nm respectively.

[0043] Please refer to Figure 3 and Figure 4 , it should be noted that the angle range of each group of LED patch lights 51 directed to the corresponding pupil light direction relative to the horizontal direction is 45 degrees-60 degrees, that is, the light emitted by each group of LED patch lights 51 only has about 45 degrees to 60 degrees relative to the horizontal direction to irradiate into the pupil but does not participate in imaging, so as to increase the ambient light under the condition that the total amount of imaging light is unchanged, and achieve the effect of preventing and controlling myopia.

[0044] Please refer to Figure 3 , wherein the specific irradiation angle of the LED patch light 51 is obtained by inputting the position of the LED patch light 51 to the pupil: high 3CM, horizontal 2CM, human eye focal length f into the eye model of the light source, through the optical design software ZWMAX, simulating the light path diagram of the light into the eye, finding the optimal incidence angle model, increasing the light into the eye while avoiding the light participating in imaging, that is, increasing the ambient light under the condition that the imaging light is unchanged, and the angle meets the high boundary light theory, so that the angle range of the LED patch light 51 directed to the pupil is about 45 degrees-60 degrees.

[0045] Please refer to Figure 1 , it also includes a power supply 7. The power supply 7 is a button lithium battery, which is installed on the opposite side of the left support 2 and the right support 3 respectively and hidden in the left support 2 and the right support 3, and also includes a charging port 8.

[0046] Wherein the power supply 7 and the control chip 53 are electrically connected, and the charging port 8 and the power supply 7 are electrically connected, when the power supply 7 is insufficient, the charger is inserted into the charging port 8 to charge the power supply 7.

[0047] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
