[0002] In the modern visual environment, high-contrast scenes (such as electronic screens, indoor reading, etc.) have become potential risk factors for myopia development.

[0044] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.
[0045] Embodiment 1:
[0046] The present invention provides a satellite point diffusion composite multi-point fog and sand multi-effect lens. Referring to Figure 1 as shown, the satellite point diffusion composite multi-point fog and sand multi-effect lens includes a lens body 1, and at least a part of the lens body 1 is provided with a point diffusion region, and the point diffusion region includes a transition point diffusion region 2, a main core point diffusion region 3 and a satellite point diffusion region 4.
[0047] The transition point diffusion region 2 is arranged at the middle position of the lens body 1, the main core point diffusion region 3 and the transition point diffusion region 2 are both arranged outside the transition point diffusion region 2, and the main core point diffusion region 3 and the satellite point diffusion region 4 coincide.
[0048] The main core point diffusion region 3 includes a plurality of main core diffusion points 31, the satellite point diffusion region 4 includes a plurality of satellite diffusion points 41, the diameter of the satellite diffusion points 41 is smaller than the diameter of the main core diffusion points 31, and the satellite diffusion points 41 and the main core diffusion points 31 are arranged alternately.
[0049] When in use, the user wears the satellite point diffusion composite multi-point fog and sand multi-effect lens, and after the light is refracted by the lens body 1, it is focused on the retina.
[0050] When light passes through the point diffusion area, under the scattering effect of the diffusion point, the imaging contrast is weakened, so that the high-contrast signal over-stimulates the eyeball, thereby playing a role in inhibiting the deepening of myopia.
[0051] In the above process, the main core point diffusion area 3 is mainly used to reduce the contrast, so that the lens reaches a certain haze value, and in the way of weakening and balancing the contrast, the light is made softer, thereby reducing the over-stimulation of the high-contrast signal to the eyeball.
[0052] On the one hand, the satellite point diffusion area 4 assists the main core point diffusion area 3 in reducing the contrast. On the basis of ensuring the light transmittance of the lens, the haze value is further increased to weaken the contrast while sacrificing less clarity to maintain a higher light transmittance. On the other hand, since the diameter of the satellite diffusion point 41 is smaller than the diameter of the main core diffusion point 31, it can also play a role in further weakening the contrast, reducing the obstacle of visual occlusion discomfort caused by too high a haze value. The purpose of designing the satellite point is to further weaken the contrast and maintain a better visual experience to make wearing more comfortable.
[0053] The transition point diffusion area 2 is used to transition the contrast difference between the central correction area of the lens body 1 and the main core point diffusion area 3 and the satellite point diffusion area 4, playing a role of connection and balance, and further improving the wearing comfort.
[0054] Embodiment 2:
[0055] Embodiment 2 is based on Embodiment 1:
[0056] As Figures 1 to 12 shown, the transition point diffusion area 2 includes a central point diffusion area, and the central point diffusion area includes a plurality of central diffusion points 21, and the diameter of the central diffusion point 21 is smaller than the diameter of the satellite diffusion point 41.
[0057] The diameters of all the central diffusion points 21 are the same.
[0058] The diameter of the central diffusion point 21 is the smallest and its haze value is the lowest, which can ensure the light transmittance of the central correction area, ensure the myopia correction effect, and does not affect the lens measurement photometry. At the same time, through the lower basic haze value provided by it, the discomfort caused by the large contrast drop is reduced.
[0059] Specifically, the central point diffusion area is arranged on the outer side of the optical center 3-7 mm of the lens body 1.
[0060] As an alternative embodiment, the transition point spread region 2 includes a gradient point spread region which is disposed outside the central point spread region. The gradient point spread region includes a plurality of gradient spread points 22. The diameter of the gradient spread points 22 is greater than the diameter of the central spread point 21 and less than the diameter of the main core spread point 31. The diameter of the gradient spread points 22 gradually increases in the direction from the inside to the outside.
[0061] With such an arrangement, the transition of the contrast change is made more natural, further improving the wearing comfort.
[0062] As an alternative embodiment, the point spread region covers the entire lens body 1.
[0063] Specifically, the lens body 1 is circular, and the regional shapes of the central point spread region, the gradient point spread region, the main core point spread region 3 and the satellite point spread region 4 are all circular.
[0064] As an alternative embodiment, the diameter of the main core spread point 31 is two times or more than two times the diameter of the satellite spread point 41, which can help improve the fog value while sacrificing less clarity, and has a high light transmittance while achieving a high fog value, reducing the visual obstacles caused by a high fog value and a low light transmittance.
[0065] As Figure 12 shown, currently, some users still have problems of esotropia, exotropia, hypertropia or hypotropia. For users with exotropia, when they use their eyes, there are three actions: convergence, accommodation, and miosis. Under the same reading distance condition, the convergence accommodation amplitude of users with exotropia is greater than that of users with normal eye positions. Therefore, for users with exotropia problems, their vision often deteriorates faster.
[0066] In view of this, the present invention provides the following embodiments with the function of correcting strabismus.
[0067] Embodiment 3
[0068] The difference between Embodiment 3 and Embodiment 2 lies in:
[0069] As Figure 2 、 Figure 3 and Figure 5 shown, on the lens body 1, the left side of the diameter in the vertical direction is set as the left region 13, and the right side of the diameter in the vertical direction is set as the right region 14.
[0070] The left region 13 and the right region 14 of the present invention are referenced to the left eye. The side away from the bridge of the nose is the left, and the left region 13 is the outer region for the user. The side close to the bridge of the nose is the right, and the right region 14 is the inner region for the user.
[0071] The point diffusion region is arranged within the right region 14, that is, the point diffusion region is arranged within the inner region.
[0072] In this way, the regional shapes of the central point diffusion region, the gradient point diffusion region, the main core point diffusion region 3, and the satellite point diffusion region 4 are all right semi-circular.
[0073] Embodiment 3 is mainly for users with esotropia.
[0074] Since the point diffusion region is concentrated in the right region 14, the contrast of the light passing through the right region 14 is weakened by the point diffusion region, and correspondingly its light transmittance is small. While the left region 13 has no point diffusion region set, so its contrast is large and the light transmittance is correspondingly large. In this way, when looking at things, the user will unconsciously look outwards. Over time, it can play a role in balancing and exercising the medial and lateral rectus muscles, making the pulling forces of the medial and lateral rectus muscles balanced, thereby playing a role in correcting esotropia, and avoiding the irreversible risks brought by strabismus surgery.
[0075] Embodiment 4
[0076] The difference between Embodiment 4 and Embodiment 3 lies in:
[0077] On the lens body 1, the left side of the diameter in the vertical direction is set as the left region 13, and the right side of the diameter in the vertical direction is set as the right region 14.
[0078] The point diffusion region is arranged within the left region 13, that is, the point diffusion region is arranged within the outer region.
[0079] In this way, the regional shapes of the central point diffusion region, the gradient point diffusion region, the main core point diffusion region 3, and the satellite point diffusion region 4 are all left semi-circular.
[0080] Similar to Embodiment 3, Embodiment 4 is mainly for users with exotropia.
[0081] Embodiment 5
[0082] The difference between Embodiment 5 and Embodiment 2 lies in:
[0083] Reference Figure 3 and Figure 6 As shown, on the lens body 1, the left side of the diameter in the vertical direction is set as the left region 13, and the right side of the diameter in the vertical direction is set as the right region 14.
[0084] The point diffusion region is arranged in both the left region 13 and the right region 14. The density of the main core diffusion points 31 in the left region 13 is less than the density of the main core diffusion points 31 in the right region 14, and the density of the satellite diffusion points 41 in the left region 13 is less than the density of the satellite diffusion points 41 in the right region 14.
[0085] In this way, the contrast of the left region 13 is greater than that of the right region 14, and the light transmittance of the left region 13 is greater than that of the right region 14.
[0086] That is, the point diffusion regions are provided both in the inner region and the outer region. The density of the diffusion points in the inner region is greater than that in the outer region. The contrast of the inner region is less than that of the outer region, and the light transmittance of the inner region is greater than that of the outer region.
[0087] In this way, during the process of viewing objects, the user will unconsciously look outwards. Over time, it can play a role in balancing and exercising the medial rectus muscle and the lateral rectus muscle, making the pulling forces of the medial rectus muscle and the lateral rectus muscle balanced, thereby playing a role in correcting esotropia.
[0088] In Example 5 for users with esotropia, compared with Example 3, since the point diffusion region is also provided in the left region 13, the change in contrast is more gentle, and it is more comfortable to wear on the basis of ensuring the vision inhibition effect.
[0089] Example 6
[0090] The difference between Example 6 and Example 5 is that:
[0091] The density of the main core diffusion points 31 in the left region 13 is greater than that of the main core diffusion points 31 in the right region 14, and the density of the satellite diffusion points 41 in the left region 13 is greater than that of the satellite diffusion points 41 in the right region 14.
[0092] In this way, the contrast of the left region 13 is less than that of the right region 14, and the light transmittance of the left region 13 is less than that of the right region 14.
[0093] That is, the density of the diffusion points in the inner region is greater than that in the outer region. The contrast of the inner region is greater than that of the outer region, and the light transmittance of the inner region is greater than that of the outer region.
[0094] Similar to Example 5, Example 6 is for users with exotropia.
[0095] Example 7
[0096] The difference between Example 7 and Example 2 is that:
[0097] Combined Figure 4 As shown, the upper side of the diameter of the lens body 1 in the horizontal direction is set as the upper region 11, and the lower side of the diameter of the lens body 1 in the horizontal direction is set as the lower region 12.
[0098] In the present invention, with the eye as a reference, for the upper region 11 and the lower region 12, the side close to the eyebrows is the upper side, and the side away from the center of the eyebrows is the lower side.
[0099] The point diffusion region is arranged in the upper region 11.
[0100] In this way, the contrast of the upper region 11 is less than that of the lower region 12, and the light transmittance of the upper region 11 is less than that of the lower region 12. The regional shapes of the central point diffusion region, the gradient point diffusion region, the main core point diffusion region 3, and the satellite point diffusion region 4 are all upper semi-circular shapes.
[0101] Similar to Embodiment 3, Embodiment 7 is mainly for users with exotropia.
[0102] Embodiment 8
[0103] The difference between Embodiment 8 and Embodiment 7 is that:
[0104] The upper side of the diameter in the horizontal direction on the lens body 1 is set as the upper region 11, and the lower side of the diameter in the horizontal direction on the lens body 1 is set as the lower region 12;
[0105] The point diffusion region is arranged in the lower region 12.
[0106] In this way, the contrast of the upper region 11 is greater than that of the lower region 12, and the light transmittance of the upper region 11 is greater than that of the lower region 12. The regional shapes of the central point diffusion region, the gradient point diffusion region, the main core point diffusion region 3, and the satellite point diffusion region 4 are all lower semi-circular shapes.
[0107] Similar to Embodiment 3, Embodiment 8 is mainly for users with esotropia.
[0108] Embodiment 9
[0109] The difference between Embodiment 9 and Embodiment 2 is that:
[0110] The upper side of the diameter in the horizontal direction on the lens body 1 is set as the upper region 11, and the lower side of the diameter in the horizontal direction on the lens body 1 is set as the lower region 12.
[0111] The point diffusion region is arranged in both the upper region 11 and the lower region 12.
[0112] The density of the main core diffusion points 31 in the upper region 11 is less than the density of the main core diffusion points 31 in the lower region 12, and the density of the satellite diffusion points 41 in the upper region 11 is less than the density of the satellite diffusion points 41 in the lower region 12.
[0113] In this way, the contrast of the upper region 11 is greater than that of the lower region 12, and the light transmittance of the upper region 11 is greater than that of the lower region 12.
[0114] Similar to Embodiment 5, Embodiment 9 is mainly for users with esotropia.
[0115] Embodiment 10
[0116] Embodiment 10 is different from Embodiment 9 in that:
[0117] The density of the main core diffusion points 31 in the upper region 11 is greater than the density of the main core diffusion points 31 in the lower region 12, and the density of the satellite diffusion points 41 in the upper region 11 is greater than the density of the satellite diffusion points 41 in the lower region 12.
[0118] Thus, the contrast of the upper region 11 is less than the contrast of the lower region 12, and the light transmittance of the upper region 11 is less than the light transmittance of the lower region 12.
[0119] Similar to Embodiment 5, Embodiment 9 is mainly for users with exotropia.
[0120] Embodiment 11
[0121] Embodiment 11 is based on any of the foregoing embodiments:
[0122] A defocusing area 5 is provided on the lens body 1, at least a part of the defocusing area 5 coincides with the point diffusion area, and the defocusing area 5 includes a plurality of defocusing parts.
[0123] The lens body 1 is configured as a concave lens, the defocusing part is configured as a convexity, and the satellite point diffusion composite multi-point fog and sand multi-effect lens is a myopia lens.
[0124] When light passes through the defocusing area 5, the defocusing part refracts the light, causing the light to be focused in front of the retina to form myopic defocus, and effectively suppressing the stretching of the eye axis through imaging ahead, thereby playing a role in suppressing the deepening of myopia.
[0125] This embodiment combines the defocusing effect with the contrast weakening effect, and the effect of suppressing the deepening of vision is more significant.
[0126] As an optional embodiment, the defocusing area 5 includes an inner defocusing area and an outer defocusing area. The inner defocusing area is arranged outside the transition point diffusion area 2 in a ring shape, the outer defocusing area is arranged outside the inner defocusing area in a ring shape, and the diameter of the defocusing part of the inner defocusing area is smaller than the diameter of the defocusing part of the outer defocusing area.
[0127] The inner defocusing area and the outer defocusing area cooperate with each other, adopt full defocus coverage, form a larger defocus area, have sufficient defocus signals, and can effectively ensure the myopic defocus effect.
[0128] As an optional embodiment, the inner defocusing area includes a plurality of first defocusing bands arranged in sequence from the inside to the outside. The first defocusing band includes a plurality of first defocusing parts 51 evenly distributed in the circumferential direction. The first defocusing band is configured as a circle or a regular hexagon, and the diameter of the first defocusing part 51 gradually increases in the direction from the inside to the outside.
[0129] The outer defocus area includes a plurality of second defocus zones arranged in sequence from inside to outside. The second defocus zones include a plurality of second defocus portions 52 evenly distributed circumferentially. The second defocus zones are set as circular or regular hexagonal, and the diameters of all the second defocus portions 52 are the same.
[0130] With such a setting, in the defocus area 5, the defocus degrees of the defocus portions first gradually increase and then remain unchanged in the direction from inside to outside, which better conforms to the characteristics of the inner spherical structure of the eye retina. On the basis of ensuring the defocus effect, it has the function of stabilizing the eye position. At the same time, the increment of the defocus degree is small, and when wearing, the glasses are hardly perceptible sensorially, having good wearing comfort.
[0131] Similar to the foregoing Embodiments 3 to 10, the satellite point spread compound multi-point mist and sand multi-effect lens having a defocus area can also play a role in correcting strabismus.
[0132] As Figure 6 shown, Figure 6 The point spread areas are provided in both its left area 13 and right area 14. The contrast of its left area 13 is greater than that of the right area 14, and the light transmittance of the left area 13 is greater than that of the right area 14, which can play a role in correcting esotropia.
[0133] Similar to Figure 6 the implementation manner shown, by setting the contrast of the left and right areas, or setting the contrast of the upper and lower areas, it can also play a role in correcting exotropia, hypertropia, and hypotropia.
[0134] As Figure 11 shown, Figure 11 The point spread area is provided in its right area 14. The contrast of its left area 13 is greater than that of the right area 14, and the light transmittance of the left area 13 is greater than that of the right area 14, which can play a role in correcting esotropia.
[0135] Similar to Figure 6 the implementation manner shown, by setting the point spread area in the left area 13, upper area 11, and lower area 12, it can also play a role in correcting exotropia, hypertropia, and hypotropia.
[0136] Embodiment 12
[0137] The difference between Embodiment 12 and any of the above embodiments is that:
[0138] The lens body 1 is set as a convex lens, the defocus portion is set as a groove or a protrusion, and the satellite point spread compound multi-point mist and sand multi-effect lens is a hyperopic lens.
[0139] When the lens passes through the defocus area 5, the defocus part refracts the light rays, causing the light rays to focus behind the retina, forming hyperopic defocus. Through imaging lag, it effectively stimulates the growth of the eye axis, thereby playing a role in suppressing deeper hyperopia.
[0140] Example 13
[0141] Example 13 is based on any of the above examples:
[0142] The present invention provides a pair of glasses, which includes the satellite point spread composite multi-point mist sand multi-effect lens.
[0143] To further verify the inhibitory effect of the present invention on eyesight, the optometry results of 50 teenagers aged 7 to 17 with good visual function wearing the satellite point spread composite multi-point mist sand multi-effect lens for about one year were collected, as shown in the following table:
[0144]
[0145]
[0146]
[0147]
[0148]
[0149]
[0150] In the above table, the serial numbers 1 to 50 are the codes of teenagers aged 7 to 17.
[0151] In the table, left represents the left eye, right represents the right eye, S- represents myopic diopter, S+ represents hyperopic diopter, C represents astigmatic diopter, and A represents the astigmatic axis angle. For example, right S-2.50C-0.50A176△8BI specifically means: the optometry result of the left eye is 250 degrees of myopia, 50 degrees of astigmatism, the astigmatic axis angle is 176 degrees, and the exotropia is 8 prism diopters (△ is prism diopter, BI represents exotropia prism base inwards); for example, right S+6.00C-1.00A90△3.5BO specifically means: the optometry result of the right eye is 600 degrees of hyperopia, 100 degrees of astigmatism, the astigmatic axis angle is 90 degrees, and the esotropia is 3.5 prism diopters (△ is prism diopter, BO represents esotropia prism base outwards, △0 represents normal).
[0152] As can be seen from the above table, among 50 teenagers, only a small number had an increase in vision, and the increase in degree generally did not exceed 25°. Most of them maintained their vision unchanged, and there was also a part with a decrease in degree, and myopia was alleviated. In addition, a small number of esotropia patients wearing hyperopic defocus lenses had their esotropic eye positions effectively developed towards the orthotropic position through semi-occlusion and the optical stimulation of hyperopic defocus imaging lag, and the eye axis would grow faster and the hyperopic degree would regress faster compared with the situation without intervention before. Exotropia can mostly return to the normal state through wearing customized multi-point defocus plus diffusion suppression interference combined with appropriate eye position training. The present invention has a significant effect of inhibiting the deepening of vision, improving strabismus, and reducing hyperopia.
