Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of myopia prevention and control, and particularly relates to a spectrum adjustment method and system for assisting myopia prevention and control. BACKGROUND

[0002] For photons, the number density and wavelength are two basic parameters. The number density represents the proportion of photons, and the wavelength represents the frequency of the photons. In the field of lighting, the illuminance and proportion represent the number density characteristics of the photons, and the color temperature and spectral power distribution represent the wavelength characteristics of the photons. Among them, the spectral power distribution (SPD) is an important parameter for describing the characteristics of a light source, which plays a crucial role in the human circadian rhythm, but researchers know little about its effect on myopia.

[0003] Previous researchers have explored the effects of different spectra on the growth of animal models' eyeballs. However, previous research has not reached a consensus on how spectral characteristics affect myopia. Hung et al. found through a rhesus monkey experiment that red light with a wavelength of 650 nm can inhibit the elongation of the eye axis of rhesus monkeys; Gawne et al. found through a study on tree shrews that red light with a wavelength of 626 nm can inhibit the growth of the eye axis of tree shrews. However, Liu et al. found through a study on young rhesus monkeys that red light with a wavelength of 610 nm can promote the growth of the eye axis of rhesus monkeys; Qian et al. found that long-wavelength monochromatic light induces myopia when studying the effects of 430 nm monochromatic light and 530 nm monochromatic light on the development of guinea pig eyeballs.

[0004] As can be seen from the above, in different previous studies, the effects of long-wavelength light and short-wavelength light on the development of axial myopia have different results, and there are contradictions among them. In addition, previous studies on the effects of wavelength on eye axis length mainly focus on red light and blue light, and the effects of yellow light and green light on eye axis development are not clear. SUMMARY

[0005] The research results of the present inventors show that long-wavelength blue light has better myopia inhibition effect than short-wavelength blue light; the myopia inhibition effect of long-wavelength red light is mainly concentrated in the two wavelength bands of 640-660 nm and 670-690 nm; green light with a wavelength of 525-555 nm not only can maintain and balance the color temperature of the light source, but also can enhance the myopia inhibition effect of blue light and yellow light to a certain extent. Therefore, appropriately adjusting the proportion combination of the four wavelength bands of 465-485 nm, 525-555 nm, 640-660 nm and 670-690 nm is expected to assist in myopia prevention and control. In view of this, the purpose of the present application is to provide a spectrum adjustment method for assisting myopia prevention and control, which adjusts the proportions of the four wavelength bands to help users prevent and control myopia and relieve the risk of myopia.

[0062] 2. Influence law of specific gravity

[0063] Assuming that the risk of myopia deepening is P, which is affected by the axial length AL of the user itself and is affected by different specific gravities, it can be regarded as a multivariate function of AL, I B , I G , I RI , I RII .

[0064] First, consider the influence of AL on P. The larger AL is, the greater the myopia baseline is, and the greater P is. When AL is less than a certain degree (no myopia or hyperopia), or greater than a certain degree (super high myopia), the change of P value caused by the change of AL will slow down. Through fitting, it can be obtained that the influence law of AL on P approximately conforms to the sigmoid function

[0065]

[0066] In the formula, , , , , are fitting parameters.

[0067] For a user with AL, different combinations of specific gravity cause different myopia risks. Suitable combinations of specific gravity will reduce P, while unsuitable combinations of specific gravity will increase P. However, regardless of the combination of specific gravity, the change in P caused by the unsuitable combination of specific gravity is within a certain range, that is, the effect of the combination of specific gravity on P is similar to the effect of AL on P. Therefore, the effect of specific gravity on P is mainly on K. The larger K is, the larger P is, and the higher the risk of myopia is. For users with different AL, the K value is affected by the combination of specific gravity in different ways, so K is affected by the combination of specific gravity and AL.

[0068] It is found that, I B , I G , I RI , I RII The effects on K are independent of each other, so I B , I G , I RI , I RII The effect law on K can be written as

[0069]

[0070] In the formula, , respectively, are the effect laws of I B , I G , I RI , I RII on .

[0071] In the visible light range, blue light and red light respectively show the characteristics of short wavelength and long wavelength, so their effects on K show opposite laws. Through fitting, the expressions of I are as follows:

[0072]

[0073]

[0074]

[0075] In the formula, , , , , , , , , , , , are fitting coefficients.

[0076] For green light, through fitting, it is found that K(IG The expression of K is as follows

[0077]

[0078] wherein, , , , are fitting coefficients, respectively.

[0079] By combining the above several formulas, the expression of K can be finally obtained as follows The expression of K is as follows

[0080]

[0081] 3. Optimal specific gravity

[0082] As can be seen from the expression of P, to make P minimum, K needs to be minimum. To obtain the minimum K value, the appropriate specific gravity combination scheme needs to be selected according to the AL value of the user. Assuming that the appropriate specific gravity combination scheme is (I B 0 , I G 0 , I Y 0 ,I R 0 ), then

[0083]

[0084]

[0085] wherein, , , , , , , , , , , , are fitting coefficients, respectively, and the combination range of (I B , I G , I RI , I RII ) values is shown in Table 1.
