Description

Technical Field

[0001] The present invention relates to the technical field of myopia glasses, and in particular to a vision control lens and glasses. Background Art

[0002] Myopia glasses work by diverging light so that the image is focused on the retina, thus overcoming the myopia problem of the image focusing in front of the retina. For myopic people whose eyes are in the developmental stage, since the peripheral optical focus of the myopia lens falls behind the retina, the eye axis will be forced to grow to receive this part of the visual information, which is not conducive to the normal development of the eye and affects normal vision.

[0003] At present, some myopia glasses have defocused micro lenses at the periphery of the lens to change the relative position of the optical focus of the periphery of the lens and the retina, thereby preventing abnormal eye development. However, the existing method of setting defocused micro lenses will result in insufficient visual clarity of the lens and cannot meet the user's vision correction needs. Summary of the invention

[0004] The present invention provides a vision control lens and glasses to solve at least part of the technical problems that the defocused microlenses included in the existing myopia lenses lead to insufficient vision clarity of the lenses and cannot meet the vision correction needs of users.

[0005] According to one aspect of the present invention, there is provided a vision control lens, comprising a lens body and defocused microlenses, wherein the defocused microlenses cover the entire lens body, and two adjacent defocused microlenses are spaced apart;

[0006] The diameter of the defocused microlens is less than 1 mm, and the ratio of the distance between two adjacent defocused microlenses to the diameter of the defocused microlens is (0-0.5):(0-1).

[0007] According to the vision control lens provided by the present invention, by distributing defocus microlenses on the lens body, an all-round defocus effect can be formed, so that the optical focus of all light rays passing through the lens body falls on the retina or in front of the retina, thereby avoiding the problem that the optical focus of a part of the lens body falls behind the retina, resulting in unclear vision. At the same time, because the defocus microlenses can make the optical focus of the lens body fall on the retina or in front of the retina, the eyeball does not need to stretch and grow to adapt to the optical focus behind the retina, avoiding the problem of forced growth of the eye axis, and ensuring the normal growth of the eyeball.

[0008] Furthermore, by controlling the diameter of the defocused microlenses and the spacing between adjacent defocused microlenses, the spacing between the defocused microlenses on the lens body, i.e., the slit width, is made small enough, so that the diffusion effect of the entire lens body for red light with a wavelength greater than 650nm can be enhanced to improve the blood circulation of the fundus, so that the diffused red light can be used to induce the retina to secrete more dopamine, so as to utilize dopamine to effectively inhibit the growth of the eye axis, prevent and control the occurrence of myopia and the increase in degree. Moreover, the diffused light is soft, less irritating to the human eye, and has high reliability.

[0009] In a further preferred embodiment, the number of the defocused microlenses is 3700 to 4300.

[0010] The defocus effect can be further enhanced by arranging a large number of defocus microlenses on the lens body to ensure that the optical focus of the light passing through the lens body falls on the retina or in front of the retina as much as possible to ensure clear vision. At the same time, it can avoid abnormal growth of the eye axis and effectively slow down the progression of myopia.

[0011] In a further preferred embodiment, the vertex power of the defocused microlens is +2.5 to +4.5D.

[0012] In this solution, the top focal length of the defocused microlens is limited so that the light refracting ability of the defocused microlens can satisfy the requirement of correcting the optical focus of the light passing through the lens body to the retina, thereby avoiding the problem of unclear vision and axial length growth caused by the optical focus of the light passing through the lens body falling behind the retina.

[0013] In a further preferred embodiment, the lens body is circular, and the defocused microlenses are distributed around the center of the lens body. The lens body is constructed to be circular and the defocused microlenses are distributed around the center of the lens body, so that it can adapt to the structure of the human eyeball, so as to cooperate with the eyeball to correct vision.

[0014] In a further preferred embodiment, the diameter of the lens body is 75 mm. In this case, the lens body can better cooperate with the human eyeball to ensure that the optical focus of the light passing through the lens body and irradiating the eyeball is focused on the retina or in front of the retina, which helps the human eye to see objects clearly.

[0015] In a further preferred embodiment, a distance between two adjacent defocused microlenses in the circumferential direction is the same as a distance between two adjacent defocused microlenses in the radial direction.

[0016] By arranging the defocused microlenses at equal distances, all the defocused microlenses can be evenly distributed on the lens body, and the gap width between adjacent defocused microlenses is small enough, thereby enhancing the diffusion effect of the lens body for red light and achieving the effect of suppressing the growth of the eye axis by red light diffusion.

[0017] In a further preferred embodiment, the diameter of the defocused microlens is 0.4-0.8 mm.

[0018] By reducing the diameter of the defocused microlenses, as many defocused microlenses as possible can be arranged when the surface area of ​​the lens is limited. At the same time, since the size of the defocused microlenses is reduced, it is beneficial to reduce the gap width between each defocused microlens, which can further enhance the diffusion effect of the lens body on red light.

[0019] In a further preferred embodiment, the distance between two adjacent defocused microlenses is 0-0.5 mm. In this case, a better red light diffusion effect can be achieved, thereby effectively inhibiting the growth of the eye axis and ensuring the normal growth of the eyeball.

[0020] In a further preferred embodiment, the defocused microlens is a convex lens. The convex lens can focus the optical focus of the light passing through the lens body on the retina or in front of the retina, thereby preventing the eye axis from growing and ensuring clear vision.

[0021] According to another aspect of the present invention, a pair of glasses is provided, comprising any one of the above-mentioned vision control lenses.

[0022] The glasses made using the above-mentioned vision control lenses not only have the effect of myopia glasses, but can also achieve a defocusing effect by using multiple defocusing microlenses on the lens body, so that the optical focus of the light passing through the lens body falls on the retina or in front of the retina, which is beneficial for the eyes to see objects clearly and can also avoid the stretching and growth of the eyeball; at the same time, the arrangement of the defocusing microlenses can enhance the diffusion effect of the lens body on red light, so as to effectively inhibit the growth of the eye axis and prevent the occurrence and degree of myopia.

[0023] In summary, the present invention provides a vision control lens and glasses, wherein the vision control lens comprises a lens body and a plurality of defocus microlenses arranged on the lens body, wherein the plurality of defocus microlenses cover the entire lens body, helping the human eye to see objects clearly, and the plurality of defocus microlenses are arranged according to certain rules, so that the slit width of each defocus microlens is as small as possible, thereby achieving a red light diffusion effect, and further utilizing red light diffusion to promote the secretion of dopamine, thereby inhibiting the growth of the eye axis through dopamine, and avoiding affecting the normal development of the eyeball.

[0040] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0041] Please refer to Figure 1 to Figure 2According to an embodiment of the present invention, the vision control lens provided at least includes: a lens body 100 and a defocused microlens 200, the defocused microlens 200 covers the entire lens body 100, and two adjacent defocused microlenses 200 are spaced apart; wherein, the diameter of the defocused microlens 200 is less than 1 mm, and the ratio of the spacing between two adjacent defocused microlenses 200 to the diameter of the defocused microlens 200 is (0-0.5):(0-1).

[0042] The lens body 100 is an effective part of the vision control lens for correcting myopia, and can prevent eye axis growth, slow down myopia, etc. In this article, the defocused microlenses 200 are all over the lens body 100, which means that all the defocused microlenses 200 are dispersed on the lens body 100, and adjacent defocused microlenses 200 are arranged at intervals and do not overlap each other.

[0043] Specifically, the lens body 100 is provided with a plurality of defocus microlenses 200, which may be convex lenses, and the optical focus of the light passing through the lens body 100 may be corrected by the defocus microlenses 200, so that the optical focus of the light passing through the lens body 100 falls on the retina or in front of the retina, ensuring that the human eye can see things clearly. Moreover, compared with the traditional lens in which the optical focus of the light passing through the lens body falls behind the retina, with the vision control lens in this embodiment, the eye axis does not need to grow to adapt to the position of the optical focus falling behind the retina, and the problem of abnormal eye axis growth can be avoided.

[0044] Furthermore, in this embodiment, the diameter of the defocused microlens 200 is controlled to be less than 1 mm and the ratio of the spacing between the defocused microlenses 200 and the diameter of the defocused microlens 200 is limited, which is beneficial to further suppress the eye axis growth based on the diffraction effect.

[0045] Specifically, based on the Fraunhofer diffraction principle, the size of the angular half width can be used as a sign of the strength of the diffraction effect. For a given wavelength, the angular half width is inversely proportional to the slit width (that is, the spacing between two adjacent defocused microlenses 200 in this embodiment), that is, the smaller the slit width, the greater the restriction on the light beam, and the more diffuse the diffraction field; on the contrary, when the slit width is larger and the light beam is almost freely propagated, the angular half width approaches zero. In addition, the angular half width is proportional to the wavelength. The longer the wavelength, the more significant the diffraction effect, and the shorter the wavelength, the more negligible the diffraction effect. For example, through Zemax OpticStudio optical software simulation, when the given wavelength is 650nm and the slit width is less than 0.32mm, the diffraction field shows obvious diffuse spots. Under the spacing range of adjacent defocused microlenses 200 defined in this embodiment, the defocused microlenses 200 can effectively diffuse the red light band. For example, the red light band of the incoming light with a wavelength greater than 650nm can be targeted and diffused, while the red light less than or equal to 650nm is not diffused and still follows the normal light path, retaining the spectral band that is beneficial to the human eye. By wearing the vision control lens of this embodiment, the vision control lens can target diffuse red light greater than 650nm to improve the blood circulation of the fundus, promote the secretion of dopamine by retinal pigment epithelial cells, increase the thickness of the choroid at the posterior pole of the eye, and increase the oxygen content of the sclera, thereby strengthening the sclera to achieve the effect of inhibiting the abnormal growth of the eye axis, and realizing the prevention and control of the occurrence and degree of myopia.

[0046] As a further preferred embodiment, based on the above-mentioned solution, the specific embodiment of the present invention may also include one or more of the following additions or combinations.

[0047] In some optional embodiments, the number of the defocused microlenses 200 is 3700 to 4300. In this embodiment, a large number of defocused microlenses 200 are distributed throughout the lens body 100. The use of a large number of defocused microlenses 200 can further enhance the defocusing effect, so as to ensure that the optical focus of all light rays passing through the lens body 100 falls on the retina or in front of the retina as much as possible, avoid the problem of unclear defocused vision due to insufficient number of defocused microlenses 200, ensure clear vision of the human eye, and avoid abnormal growth of the eye axis.

[0048] In some optional embodiments, the vertex power of the defocused microlens 200 is +2.5 to +4.5 D. The refractive power of the defocused microlens 200 within this vertex power range can meet the requirement of correcting the optical focus of the light passing through the lens body 100 to the retina, thereby avoiding the problem of unclear vision and eye axis lengthening caused by the optical focus of the light passing through the lens body 100 falling behind the retina.

[0049] Optionally, the top focal length of the defocused microlens 200 can be controlled to be +2.5 to +3D, in which case the defocusing effect of the defocused microlens 200 can be further enhanced to ensure that the human eye can see objects clearly.

[0050] In some optional embodiments, the lens body 100 is circular, and the defocused microlenses 200 are distributed around the center of the lens body 100. The lens body 100 is constructed to be circular and the defocused microlenses 200 are distributed around the center of the lens body 100, so that it can adapt to the structure of the human eyeball, so as to cooperate with the eyeball to correct vision. Specifically, in this embodiment, the defocused microlenses 200 are distributed all over the circular lens body 100, and the light passing through the defocused microlenses 200 on the lens body 100 will be defocused by the defocused microlenses 200, so that the optical focus of all the light passing through the lens body 100 can fall on the retina or in front of the retina as much as possible, so as to form a full range of vision correction, thereby ensuring clear vision.

[0051] In some optional embodiments, the diameter of the lens body 100 is 75 mm. In this case, the lens body 100 can better match the size of the human eyeball to ensure that the optical focus of the light passing through the lens body 100 and irradiating the eyeball is focused on the retina or in front of the retina, which helps the human eye to see objects clearly.

[0052] In some optional embodiments, the spacing between two adjacent defocus microlenses 200 in the circumferential direction is the same as the spacing between two adjacent defocus microlenses 200 in the radial direction.

[0053] Further references Figure 1 , all the defocused microlenses 200 are arranged on the lens body 100, and are distributed around the center of the lens body 100 and arranged equidistantly in pairs. Specifically, in the circumferential direction of the circular lens body 100, the spacing between adjacent defocused microlenses 200 is the same, and at the same time, in the radial direction of the circular lens body 100, the spacing between adjacent defocused microlenses 200 is also the same. By evenly arranging the defocused microlenses 200 on the lens body 100, the spacing between the defocused microlenses 200 can be made small enough, that is, the gap width between the defocused microlenses 200 is small enough, which is conducive to enhancing the diffusion effect of the lens body 100 for red light.

[0054] In some optional embodiments, the diameter of the defocused microlens 200 is 0.4-0.8 mm. Since the surface area of ​​the lens body 100 is limited, in order to minimize the spacing between adjacent defocused microlenses 200, the diameter of the defocused microlens 200 is controlled to be 0.4-0.8 mm in this embodiment, so that the gap width between adjacent defocused microlenses 200 can be minimized while ensuring the defocusing effect of the defocused microlens 200, and the diffusion effect of the lens body 100 on red light can be further enhanced.

[0055] In some optional embodiments, a coating layer is provided on one side of the lens body 100 to protect the lens body 100 .

[0056] Reference Figure 2 A coating layer with various functions can be set on the side of the lens body 100, and the coating layer can be plated on the side of the lens body 100 through a corresponding coating process, which can protect the lens body 100 and enable the lens body 100 to have various functions.

[0057] For example, the coating layer can be at least one of an anti-reflection film 110, a diamond film 120, and an ultra-waterproof film 130. The anti-reflection film 110 can be added with zirconium to increase the film hardness. The anti-reflection film 110 can reduce the reflected light on the lens surface, making the vision clear. The diamond film 120 can effectively enhance the overall hardness of the lens body 100 and increase the light transmittance. The ultra-waterproof film 130 can prevent the mirror surface from being contaminated with oil.

[0058] In order to make the purpose, technical solutions and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. However, the described specific embodiments are only used to explain the present invention and are not used to limit the present invention.
