[0002] Myopia is a social problem. Studies have shown that myopic defocus can effectively inhibit axial elongation and may even shorten the axial length. The so-called myopic defocus (also known as positive defocus) stimulation refers to the phenomenon where, when the human eye focuses on an image plane that can be clearly imaged on the retina, called the principal image plane, if another image plane or part of the principal image plane can be imaged simultaneously in front of the retina through optical means, a positive defocus stimulation is formed in optometry. Axial chromatic aberration (LCA) can generate myopic defocus stimulation under appropriate induction, thereby inhibiting axial elongation. Summary of the Invention

[0129] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0130] To facilitate understanding of the embodiments of this application, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this application.

[0131] Axial myopia defocusing has been shown to have a certain effect on inhibiting myopia. Its working principle is as follows: Figure 1 As shown, when the human eye focuses on an image plane, that image plane can be clearly imaged on the retina 1, and is called the principal image plane. If, through optical means, another image plane is presented in front of the retina 1 when the principal image plane falls on the retina 1, the two image planes work together to form axial myopic defocus, causing the eye to have a tendency to want to see the image presented in front of the retina 1 clearly, driving the retina 1 to move forward to inhibit the elongation of the eye axis, and may even reduce the degree of myopia.

[0132] Because different colors of light have different wavelengths and different refractive indices in the same medium, they focus at different focal points. Furthermore, when different colors of light enter the eye, due to their different wavelengths, some colors will focus in front of the retina, while others will focus behind it. If the focal point furthest from the retina can be controlled and directed onto the retina using optical means, the shorter wavelength light will focus in front of the retina, creating myopic defocus. This can, to some extent, inhibit the elongation of the eye axis and effectively alleviate or even treat myopia.

[0133] Example 1

[0134] This embodiment provides an image display method, such as Figure 2-4 As shown.

[0135] The image display method includes acquiring a first color value of a predetermined pixel in the image to be displayed. The first color value includes attribute values ​​of each primary color based on additive color mixing, wherein each primary color includes at least a first primary color and a second primary color, and the wavelength of the first primary color is at least 50 nm larger than the wavelength of the second primary color.

[0136] The presented image is composed of multiple pixels, which display a certain color according to a certain arrangement. That is, each pixel has coordinate parameters and color values, and a predetermined pixel has a first color value.

[0137] The primary colors in the first color value can be any of the primary colors that make up the three primary colors of optics, or any of the primary colors under a color mechanism based on the deformation of the three primary colors of optics, or any of the primary colors under other color mechanisms, as long as they can be primary colors in the color mechanism of additive color mixing. Preferably, the primary colors are the three primary colors of optics. This division mechanism is widely used, and most imaging screens use this mechanism to display different colors for each pixel.

[0138] Obtaining the first color value of a predetermined pixel in the presented image includes reading the coordinate parameters of the predetermined pixel and then reading the attribute values ​​of each primary color constituting the presented color under the coordinate parameters.

[0139] The difference between the first and second wavelengths is limited to greater than 50 nm to form myopic defocus through axial chromatic aberration and suppress axial elongation.

[0140] Furthermore, the primary colors in the color space of the presented image include the three primary colors R, G, and B. The first primary color includes the color presented when the G attribute value and B attribute value are 0 in the RGB three primary colors, and the R attribute value is greater than 0. The second primary color includes the color presented when the R attribute value and G attribute value are 0 in the RGB three primary colors, and the B attribute value is greater than 0. The corresponding intensity adjustment ratio needs to adjust the relative ratio of the attribute values ​​of the three primary colors R, G, and B.

[0141] For example, the obtained first color value is represented as (R ij G ij B ij ), where R ij G is the R attribute value of the pixel in the i-th row and j-th column of the presented image. ij To represent the G attribute value of the pixel in the i-th row and j-th column of the image, B ij To display the B attribute value of the pixel in the i-th row and j-th column of the image.

[0142] After obtaining the first color value, the attribute values ​​of each primary color in the first color value are adjusted according to the intensity adjustment ratio to obtain the second color value used for presentation. This includes: obtaining the intensity adjustment ratio coefficient of each primary color based on myopia defocus stimulation; adjusting the first color value according to the intensity adjustment ratio coefficient to obtain the second color value, wherein the difference between the attribute value of the first primary color and the attribute value of the second primary color in the second color value is greater than the difference between the attribute value of the first primary color and the attribute value of the second primary color in the first color value. That is, the absolute value of the difference between the attribute value of the first primary color and the attribute value of the second primary color is greater than the absolute value of the difference between the attribute value of the first primary color and the attribute value of the second primary color in the first color value. Since the presented image includes the attribute values ​​of each primary color, if the presented image is to be adjusted, the attribute values ​​of each primary color need to be changed. Furthermore, the second color attribute value is obtained by changing the attribute values ​​of each primary color in the first color value of the presented image according to the intensity adjustment ratio, thus constructing a new presented image.

[0143] It should be noted that the two steps of obtaining the first color value and obtaining the intensity adjustment ratio are not sequential. You can obtain the first color value first and then obtain the intensity adjustment ratio, or you can obtain the intensity adjustment ratio first and then obtain the first color value.

[0144] Methods for obtaining the intensity adjustment ratio include, but are not limited to, directly inputting the intensity adjustment ratio or obtaining an intensity adjustment ratio based on detection. Detection-based methods can yield more targeted and personalized intensity adjustment ratios, suitable for different observers' eye conditions. The intensity adjustment ratio obtained from detection can be achieved using software or methods other than those disclosed herein, and the presented image can be altered based on the obtained intensity adjustment ratio; alternatively, it can be obtained using the methods mentioned in this disclosure, and the presented image can be adjusted using the intensity adjustment ratio.

[0145] Since red light has a relatively long wavelength and blue light has a relatively short wavelength, for the three primary colors of light, therefore, as Figure 3 As shown, when red light 2 and blue light 3 enter the eye simultaneously, the focal point formed by red light 2 will fall behind retina 1, while the focal point formed by blue light 3 will fall in front of retina 1. Based on the relationship between wavelength and refractive index, the axial distance between the focal points of blue and red light in the human eye is approximately 0.5 mm. Under appropriate induction, this can produce myopic defocus stimulation. Normally, the focal points formed by blue light 3 and red light 2 are located in front of and behind the retina, respectively, creating traction forces in two opposite directions. When the light intensities change, the traction forces also change, thereby stimulating the lens's accommodation to balance the traction forces. By controlling the light intensity, the focal points formed by red light and blue light can be shifted forward. Figure 4 As shown, by increasing the brightness of red light 2 while decreasing the brightness of blue light 3, the focus of red light 2 is induced to be focused on the macula of the fovea of ​​retina 1, while the focus of blue light 3 and green light will be located in front of retina 1, thereby generating a force that pulls the retina forward, so as to inhibit or even shorten the axial length of the eye, thereby slowing down the degree of myopia.

[0146] Based on the above principle, it is necessary to obtain an intensity adjustment ratio suitable for the observer based on the optotype image, and adjust the intensity adjustment parameters of R, G, and B of the presented image to ultimately present an image that can effectively suppress the elongation of the observer's eye axis. The optotype image includes a first optotype image and a second optotype image. The first optotype image is in a first primary color, and the second optotype image is in a second color. The first optotype image appears as a first image in the observer's eye, and the second optotype image appears as a second image in the observer's eye. The method for detecting the intensity adjustment ratio includes the following steps:

[0147] The observer continuously observes the first target image at a preset distance from the first image. The brightness of the first target image changes from small to large until the edge of the first image falls on the observer's retina, thus obtaining a first critical target image. A first attribute value is obtained based on the first critical target image.

[0148] The first brightness variation from small to large includes increasing the R attribute value in the first visual target image until the edge of the first image falls on the observer's retina. At this point, the first visual target image is the first critical visual target image. During the brightness variation, the observer will continuously observe the first visual target image until the edge of the first visual target image can be clearly and sharply seen, thus obtaining the first critical visual target image for that observer. In the first critical visual target image, both the B and G attribute values ​​are 0, and the R attribute value is the first attribute value. This setting allows for adjustment based on the different eye conditions of different observers until a suitable first critical visual target image is obtained.

[0149] The preset distance is 3-5m, and the first visual target image is arranged within the observer's 0-5° field of view. Setting the preset distance aims to provide conditions for myopic defocus induced by axial chromatic aberration in the human eye. Because in near-vision scenarios, the focal point falls slightly behind the retina, resulting in less accommodative force being used than needed—a phenomenon known as accommodative lag—which causes or exacerbates myopia. Even when using axial chromatic aberration to stimulate lens accommodation and suppress axial elongation in near-vision scenarios, the negative effects of accommodative lag still outweigh the positive effects of axial chromatic aberration. Therefore, it is necessary to control the observer to view at a relatively far distance, specifically 3-5m. The field of view of the presented image is set so that the first and second images fall at the center of the eyeball, which is beneficial for stimulating the lens's accommodative function.

[0150] When the observer continuously observes the first critical target image at a preset distance from the first image, the second brightness of the second target image gradually increases until the edge of the first image is at a critical position about to leave the observer's retina, thus obtaining a second critical adjustment image. A second attribute value is then obtained based on this second critical image. Increasing the second brightness aims to enhance the stimulation of the second target image on the first critical target image. The second target image and the first critical target image form an axial chromatic aberration to produce myopic defocus, thereby inhibiting axial elongation and alleviating or even treating myopia. Furthermore, a second critical target adjustment image tailored to the observer's visual condition can be obtained based on different eye conditions.

[0151] The intensity adjustment ratio is obtained based on the first attribute value and the second attribute value. A third attribute value is set to be the same as the second attribute value, where the third attribute value represents the G attribute value. The ratio of the first attribute value, the second attribute value, and the third attribute value is the intensity adjustment ratio.

[0152] The above method can obtain a targeted intensity adjustment ratio adapted to different observers. This ratio can greatly reduce the elongation of the observer's eye axis by changing the displayed image to create myopia defocus.

[0153] The intensity adjustment ratio obtained from the first attribute value, the second attribute value, and the third attribute value is expressed as: R1:G1:B1, where R1 is the R intensity ratio adjustment coefficient, G1 is the G intensity ratio adjustment coefficient, and B1 is the B intensity ratio adjustment coefficient. When the first color value is (R ij G ij B ij When the intensity ratio is adjusted, the second color value (R) is obtained. ij ', G ij ', B ij '). Among them, R ij G is the R attribute value of the pixel in the i-th row and j-th column of the presented image. ij To represent the G attribute value of the pixel in the i-th row and j-th column of the image, B ij To represent the B attribute value of the pixel in the i-th row and j-th column of the image; R ij To display the R attribute value of the pixel in the i-th row and j-th column after adjusting the intensity ratio, G ij To display the G attribute value of the pixel in the i-th row and j-th column after adjusting the intensity ratio, B ij 'The B attribute value of the pixel in the i-th row and j-th column after the image is adjusted according to the intensity adjustment ratio.'

[0154] The correspondence between the first color value and the second color value is: R ij '=R ij , By reducing the G and B attribute values ​​to highlight the R attribute value, the image is made to appear reddish as much as possible. The entire image forms a longitudinal light difference, causing the observer to experience myopic defocus, which tends to pull the retina forward, thereby inhibiting axial elongation and even shortening the axial length.

[0155] After a preset time, the R intensity ratio adjustment coefficient is increased to R1'. Within the preset time, the observer can adapt to the reddish interface of the displayed image; after the observer adapts, the R intensity ratio coefficient is increased to enhance the proportion of red in the ratio, increase the myopic defocus effect caused by axial color difference, and suppress axial elongation more strongly, thus slowing down the degree of myopia. When the R intensity ratio adjustment coefficient is increased, the G intensity ratio adjustment coefficient and the B intensity ratio adjustment coefficient remain unchanged, resulting in a new intensity adjustment ratio, denoted as R1':G1':B1', where the first color value is represented as (R ij Gij B ij The second color value corresponding to the first color value is represented as (R). ij ', G ij ', B ij If '), then the correspondence between the first color value and the second color value is expressed as R. ij '=R ij ,

[0156] Once the preset time is reached, the R intensity can be adjusted again according to the observer's actual situation to further enhance the axial chromatic aberration of the presented image, causing the observer to experience stronger myopic defocus to further suppress axial elongation.

[0157] It should be noted that when the intensity adjustment ratio is changed once, the first color value of the image before the change is represented as (R). ij G ij B ij The resulting second color value is represented as (R). ij ', G ij ', B ij When the intensity adjustment ratio is changed, the previous second color value becomes the current first color value, and a new second color value is obtained based on the intensity adjustment ratio. As the intensity adjustment ratio changes, the previous second color value will be continuously assigned to the new first color value.
