[0002] As the incidence of myopia increases year by year, and myopia is developing towards a younger age and more severe trend, most of the reasons are due to not maintaining good eye habits in life and study, such as not keeping an appropriate distance when doing homework, and looking at electronic devices in dim light environments. Especially for students taking online classes, the time and frequency of using electronic products have increased, leading to frequent poor eyesight.

[0003] If children develop myopia too early, it will greatly increase the incidence of high myopia, leading to blinding eye diseases such as retinal detachment, retinal atrophy, and macular hemorrhage, which seriously endangers vision health. Therefore, how to control the development of myopia and reduce the incidence of myopia has always been a key issue of social concern. Summary of the invention

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] As the incidence of myopia increases year by year, and myopia is developing towards a younger age and more severe, premature myopia in children will greatly increase the incidence of high myopia, leading to blinding eye diseases such as retinal detachment, retinal atrophy, and macular hemorrhage, which seriously endangers vision health. Therefore, how to control the development of myopia and reduce the incidence of myopia has always been a key issue of social concern.

[0018] The present invention is based on the high-light theory and adopts a scattered light source to achieve myopia prevention and control. The high-light theory is introduced as follows: 1. The division of light entering the eye according to the high-level light theory The high-level light theory divides the light entering the human eye into two categories: one is the light that participates in imaging, called imaging light; the other is the light that does not participate in imaging and only provides light perception, called ambient light.

[0019] 2. The High-level Light Theory consists of the above three principles: Principle 1: When the light that forms visual perception (the total light entering the eye) 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 to controlling the occurrence, development and growth of myopia; otherwise, the more unfavorable it is.

[0020] Principle 2: When the ratio of imaging light and ambient light is constant, the greater the total amount of light that forms visual perception, the better the visual effect it can provide, the clearer the imaging, and the more beneficial it is to controlling the occurrence, development and axial length of myopia; conversely, the more disadvantageous it is.

[0021] Principle 3: The necessary condition for imaging 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, no image can be formed.

[0022] See also Figure 1 , based on the above theoretical basis. This embodiment provides a supplementary light instrument equipped with a scattered light source, including a beam frame 1, a left bracket 2 and a right bracket 3 are respectively arranged on both sides of the beam frame 1, and a nose bridge 4 is arranged on the lower side of the beam frame 1. The left bracket 2 and the right bracket 3 are used to be mounted on the auricle, and the nose bridge 4 is placed on the bridge of the nose, so that the beam frame 1 is mounted near the eye.

[0023] The crossbeam frame 1 is provided with a light emitting module 5, and the light emitting module 5 can adjust the angle of the emitted light source based on the eye distance and glasses wearing habits of Asian children.

[0024] The specific work is that the wearer places the left bracket 2 and the right bracket 3 of the fill light device on the auricle, the nose bracket 4 on the nose bridge, and sets up the fill light device on the head. Then the light emitting module 5 emits a light source, and the light source passes through the human eye refractive system and enters the corresponding pupil. When the light source emitted by the light emitting module 5 enters the corresponding eye, the propagation direction deviates from the image point (the image point is the image point formed when other light sources enter the corresponding eye), thereby increasing the light entering the eye while avoiding the light from participating in imaging, that is, increasing the ambient light while keeping the imaging light unchanged.

[0025] Detailed introduction of light-emitting module 5: See also Figure 1 and Figure 2 The light-emitting module 5 includes two groups of LED patch lights 51 arranged on the crossbeam frame 1, respectively located on both sides of the nose bridge 4, as well as a light sensor 52 arranged on the outside of the crossbeam frame 1 and a control chip 53 arranged inside the crossbeam frame 1, wherein the LED patch lights 51 and the light sensor 52 are both electrically connected to the control chip 53.

[0026] The light source emitted by the light module 5 is mainly composed of the light emitted by two groups of LED patch lights 51, and the light sensor 52 and the control chip 53 are mainly used to control the light intensity of the LED patch lights 51. As the wearer moves around, the intensity of the light in the external environment also changes, so the light intensity of the LED patch lights 51 needs to be adjusted accordingly to meet the appropriate ratio of ambient light to imaging light.

[0027] The specific operation is as follows: the external ambient light shines on the light sensor 52 , the light sensor 52 transmits the light intensity to the control chip 53 through an electrical signal, the control chip 53 transmits the electrical signal to the LED patch light 51 , and thereby adjusts the intensity of the LED patch light 51 .

[0028] When the light intensity in the external environment increases, the light sensor 52 senses an electrical signal and transmits it 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 light intensity in the external environment decreases, the light sensor 52 senses an electrical signal and transmits it to the control chip 53, and the control chip 53 controls the brightness of the two groups of LED patch lights 51 to decrease, thereby automatically adjusting the ambient light according to the intensity of the light in the external environment.

[0029] The approximate range of the external environment light intensity and the brightness of the LED patch lamp (51) is as follows:

[0030] See also Figure 1It should be noted that the specific position of each group of LED patch lights 51 is located on the side of the crossbeam frame 1 close to the head. The crossbeam frame 1 is provided with a placement groove 6 for placing the LED patch lights 51. The height distance of the LED patch lights 51 from the pupil is 2cm-3cm, and the horizontal distance of the LED patch lights 51 from the pupil is approximately 1.5cm-2cm.

[0031] The LED patch lamp 51 has a luminous wavelength of 500 nanometers to 900 nanometers, a warm white light, and an illumination of 100 LUX to 500 LUX.

[0032] See also Figure 1 and Figure 2 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 configured from the temporal side to the nasal side are 500 nanometers, 600 nanometers, 700 nanometers, 800 nanometers and 900 nanometers respectively.

[0033] See also Figure 3 and Figure 4 It should be noted that the angle range of the illumination direction of each group of LED SMD lights 51 to the corresponding pupil relative to the horizontal direction is 45 degrees to 60 degrees, that is, the light irradiated to the outside by each group of LED SMD lights 51, only the light at about 45 degrees to 60 degrees relative to the horizontal direction enters the pupil but does not participate in the imaging, thereby ensuring that the total amount of imaging light remains unchanged and the ambient light is increased to achieve the effect of preventing and controlling myopia.

[0034] See also Figure 3 The specific irradiation angle of the LED SMD lamp 51 is obtained by placing the LED SMD lamp 51 at the position of the pupil: 3CM in height and 2CM in level, and inputting the focal length f of the human eye into the astigmatic light source entry model. The optical design software ZWMAX is used to simulate the optical path diagram of the light entering the eye, and the optimal incident angle model is found. While increasing the light entering the eye, the light is prevented from participating in the imaging. That is, when the imaging light remains unchanged, the ambient light is increased to meet the angle of the high ambient light theory, thereby concluding that the angle of the LED SMD lamp 51 to the pupil is approximately in the range of 45 degrees to 60 degrees.

[0035] See also Figure 1 , and also includes a power supply 7. The power supply 7 is a button lithium battery, which is respectively installed on the side opposite to the left bracket 2 and the right bracket 3, and is hidden in the left bracket 2 and the right bracket 3, and also includes a charging port 8.

[0036] The power source 7 is electrically connected to the control chip 53 , and the charging port 8 is electrically connected to the power source 7 . When the power source 7 is low on power, the charger is plugged into the charging port 8 to charge the power source 7 .

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
