Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens technology, specifically to a satellite point diffusion verification multi-point fogging multi-effect lens and eyeglasses. Background Technology
[0002] In the modern visual environment, high-contrast scenes (such as electronic screens and indoor reading) have become a potential risk factor for the development of myopia.
[0003] To address this, a type of frosted lens has emerged that suppresses vision progression by reducing contrast. The center of the lens is the optical correction zone, and multiple diffusion points are distributed around the outer edge of the optical correction zone. These diffusion points form a frosted area to reduce contrast. However, in existing frosted lenses, the contrast difference between the diffusion points within the diffusion zone and the central correction zone of the lens is significant. This not only affects the vision progression suppression effect due to the imbalance in fogging values, but also causes discomfort when wearing the lens, impacting the user experience.

On the other hand, its smaller diameter diffusion points have a transitional function, reducing visual obstacles caused by changes in contrast differences.
[0027] This invention utilizes the cooperation of the main core diffusion area, satellite diffusion area, and transition diffusion area. On the one hand, it provides a certain haze value while ensuring the light transmittance of the lens, thereby reducing the contrast and inhibiting the progression of vision problems.

Detailed Implementation
[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0044] Example 1:
[0045] This invention provides a satellite point diffusion verification multi-point fogging multi-effect lens, for reference. Figure 1 As shown, the satellite point diffusion core multi-point fog and sand multi-effect lens includes a lens body 1, and at least a portion of the lens body 1 is provided with a point diffusion area, which includes a transition point diffusion area 2, a main core point diffusion area 3 and a satellite point diffusion area 4.
[0046] The transition point diffusion region 2 is located in the middle of the lens body 1. The main core diffusion region 3 and the transition point diffusion region 2 are both located outside the transition point diffusion region 2. The main core diffusion region 3 and the satellite point diffusion region 4 overlap.
[0047] The main core diffusion region 3 includes multiple main core diffusion points 31, and the satellite diffusion region 4 includes multiple 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.
[0048] When in use, the user wears the satellite point diffusion verification multi-point fogging multi-effect lens. After the light is refracted by the lens body 1, it is focused onto the retina.
[0049] When light passes through the point diffusion area, the imaging contrast is weakened by the scattering effect of the diffusion point, thus the high contrast signal overstimulates the eyeball, thereby inhibiting the progression of vision problems.
[0050] In the above process, the main core diffusion region 3 is mainly used to reduce the contrast, so that the lens reaches a certain haze value, thereby weakening and balancing the contrast, making the light softer, and thus reducing the excessive stimulation of the eyeball by high contrast signals.
[0051] The satellite dot diffusion area 4 assists the main core dot diffusion area 3 in reducing contrast. While ensuring the light transmittance of the lens, it further increases the haze value to reduce contrast and sacrifice less clarity to maintain higher light transmittance. On the other hand, since the diameter of the satellite dot diffusion area 41 is smaller than that of the main core diffusion area 31, it can also further reduce the contrast and reduce the visual obstruction caused by excessive haze value. The purpose of designing the satellite dot is to further reduce the contrast, maintain a better visual experience, and make wearing more comfortable.
[0052] The transition point diffusion zone 2 is used to bridge the contrast difference between the central correction zone of the lens body 1 and the main core diffusion zone 3 and satellite diffusion zone 4, playing a role in connecting and balancing, and further improving wearing comfort.
[0053] Example 2:
[0054] Example 2 is based on Example 1:
[0055] like Figures 1 to 12 As shown, the transition point diffusion region 2 includes a center point diffusion region, which includes multiple center diffusion points 21, the diameter of which is smaller than the diameter of the satellite diffusion points 41.
[0056] All central diffusion points 21 have the same diameter.
[0057] The central diffusion point 21 has the smallest diameter and the lowest haze value, which can ensure the light transmittance of the central correction area, ensure the vision correction effect, and not affect the lens measurement power. At the same time, by providing a lower base haze value, it reduces the discomfort caused by large contrast difference.
[0058] Specifically, the central point diffusion area is located 3 to 7 mm outside the optical center of the lens body 1.
[0059] As an optional implementation, the transition point diffusion region 2 includes a gradient point diffusion region, which is located outside the center point diffusion region. The gradient point diffusion region includes a plurality of gradient diffusion points 22, the diameter of which is larger than the diameter of the center diffusion point 21 and smaller than the diameter of the main core diffusion point 31; the diameter of the gradient diffusion points 22 gradually increases from the inside to the outside.
[0060] This setting makes the contrast transition more natural, further improving wearing comfort.
[0061] As an optional implementation, the dot diffusion region covers the entire lens body 1.
[0062] Specifically, the lens body 1 is circular, and the central point diffusion area, the gradient point diffusion area, the main core point diffusion area 3, and the satellite point diffusion area 4 are all circular in shape.
[0063] As an optional implementation, the diameter of the main core diffusion point 31 is twice or more than twice the diameter of the satellite diffusion point 41, which can help improve the fog value while sacrificing less clarity. It achieves a high fog value while also having high light transmittance, reducing the visual obstacles caused by high fog value and low light transmittance.
[0064] like Figure 12 As shown, some users currently have problems with esotropia, exotropia, hypertropia, or hypotropia. For users with exotropia, there are three actions when they use their eyes: convergence, accommodation, and pupil constriction. Under the same reading distance conditions, users with exotropia have a greater convergence and accommodation amplitude than users with normal eye position. Therefore, users with exotropia tend to experience a faster decline in vision.
[0065] In response, this utility model provides the following implementation method that has the function of correcting strabismus.
[0066] Example 3
[0067] The difference between Example 3 and Example 2 is that:
[0068] like Figure 2 , Figure 3 and Figure 5 As shown, the left side of the vertical diameter of the lens body 1 is designated as the left region 13, and the right side of the vertical diameter of the lens body 1 is designated as the right region 14.
[0069] The left region 13 and right region 14 of this utility model are referenced to the left eye. The side away from the center of the eyebrows is the left. The left region 13 is the outer region for the user, the side closer to the center of the eyebrows is the right, and the right region 14 is the inner region for the user.
[0070] The point diffusion area is set within the right region 14, that is, the point diffusion area is set within the inner region.
[0071] Thus, 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-circles.
[0072] Example 3 is primarily for users with esotropia.
[0073] Since the dot diffusion area is concentrated in the right region 14, the contrast of light passing through the right region 14 is weakened by the dot diffusion area, resulting in lower light transmittance. On the other hand, the left region 13 does not have the dot diffusion area, so its contrast is higher and its light transmittance is correspondingly higher. As a result, when viewing objects, the user will unconsciously look outward. Over time, this can help balance the internal and external rectus muscles, thereby balancing their tension and correcting esotropia, thus avoiding the irreversible risks associated with strabismus surgery.
[0074] Example 4
[0075] The difference between Example 4 and Example 3 is as follows:
[0076] The left region 13 is located on the left side of the vertical diameter of the lens body 1, and the right region 14 is located on the right side of the vertical diameter of the lens body 1.
[0077] The point diffusion area is set within the left region 13, that is, the point diffusion area is set within the outer region.
[0078] Thus, the central point diffusion region, the gradient point diffusion region, the main core point diffusion region 3, and the satellite point diffusion region 4 all have a left semi-circular shape.
[0079] Similar to Example 3, Example 4 is mainly for users with exotropia.
[0080] Example 5
[0081] The difference between Example 5 and Example 2 is that:
[0082] refer to Figure 3 and Figure 6 As shown, the left side of the vertical diameter of the lens body 1 is designated as the left region 13, and the right side of the vertical diameter of the lens body 1 is designated as the right region 14.
[0083] The point diffusion regions are provided 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 that in the right region 14, and the density of the satellite diffusion points 41 in the left region 13 is less than that in the right region 14.
[0084] Thus, the contrast of the left region 13 is greater than that of the right region 14, and the transmittance of the left region 13 is greater than that of the right region 14.
[0085] That is, both the inner region and the outer region are provided with the point diffusion area, the density of diffusion points in the inner region is greater than the density of diffusion points in the outer region, the contrast of the inner region is less than the contrast of the outer region, and the light transmittance of the inner region is greater than that of the outer region.
[0086] In this way, during the process of viewing objects, users will unconsciously look outward. Over time, this can help balance the internal and external rectus muscles, thereby correcting esotropia.
[0087] Example 5 is designed for users with esotropia. Compared to Example 3, Example 5 also has the dot diffusion area set in the left region 13, so the contrast change is softer and the wearing is more comfortable while ensuring the visual suppression effect.
[0088] Example 6
[0089] The difference between Example 6 and Example 5 is that:
[0090] The density of the main core diffusion point 31 in the left region 13 is greater than that in the right region 14, and the density of the satellite diffusion point 41 in the left region 13 is greater than that in the right region 14.
[0091] Thus, the contrast of the left region 13 is less than that of the right region 14, and the transmittance of the left region 13 is less than that of the right region 14.
[0092] That is, the density of 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 transmittance of the inner region is greater than that of the outer region.
[0093] Similar to Example 5, Example 6 is for users with exotropia.
[0094] Example 7
[0095] The difference between Example 7 and Example 2 is that:
[0096] Combination Figure 4 As shown, the upper region 11 is located on the upper side of the horizontal diameter of the lens body 1, and the lower region 12 is located on the lower side of the horizontal diameter of the lens body 1.
[0097] The upper region 11 and lower region 12 of this utility model are referenced to the eyes, with the side closer to the eyebrows being the upper region and the side farther from the center of the eyebrows being the lower region.
[0098] The point diffusion zone is located within the upper region 11.
[0099] Thus, 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 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-circles.
[0100] Similar to Example 3, Example 7 is primarily aimed at users with upward strabismus.
[0101] Example 8
[0102] The difference between Example 8 and Example 7 is as follows:
[0103] The upper region 11 is located on the upper side of the horizontal diameter of the lens body 1, and the lower region 12 is located on the lower side of the horizontal diameter of the lens body 1.
[0104] The point diffusion zone is located within the lower region 12.
[0105] Thus, 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 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-circles.
[0106] Similar to Example 3, Example 8 is primarily aimed at users with hypotropia.
[0107] Example 9
[0108] The difference between Example 9 and Example 2 is that:
[0109] The upper region 11 is located on the upper side of the horizontal diameter of the lens body 1, and the lower region 12 is located on the lower side of the horizontal diameter of the lens body 1.
[0110] The point diffusion zone is set in both the upper region 11 and the lower region 12.
[0111] The density of the main core diffusion point 31 in the upper region 11 is less than that in the lower region 12, and the density of the satellite diffusion point 41 in the upper region 11 is less than that in the lower region 12.
[0112] Thus, the contrast of the upper region 11 is greater than that of the lower region 12, and the transmittance of the upper region 11 is greater than that of the lower region 12.
[0113] Similar to Example 5, Example 9 is primarily aimed at users with hypotropia.
[0114] Example 10
[0115] The difference between Example 10 and Example 9 is as follows:
[0116] The density of the main core diffusion point 31 in the upper region 11 is greater than that in the lower region 12, and the density of the satellite diffusion point 41 in the upper region 11 is greater than that in the lower region 12.
[0117] Thus, the contrast of the upper region 11 is less than that of the lower region 12, and the transmittance of the upper region 11 is less than that of the lower region 12.
[0118] Similar to Example 5, Example 9 is primarily aimed at users with upward strabismus.
[0119] Example 11
[0120] Example 11 is based on any of the foregoing examples:
[0121] The lens body 1 is provided with a defocus area 5, at least a portion of which overlaps with the dot diffusion area. The defocus area 5 includes multiple defocus portions.
[0122] The lens body 1 is set as a concave lens, the defocusing part is set as a convex part, and the satellite point diffusion verification multi-point fogging multi-effect lens is a myopia lens.
[0123] When light passes through the defocus zone 5, the defocus zone refracts the light, causing the light to focus in front of the retina, forming myopic defocus. By advancing the image, it effectively inhibits the stretching of the eye axis, thereby inhibiting the progression of myopia.
[0124] This implementation combines defocusing with contrast reduction, resulting in a more significant effect in inhibiting the progression of vision problems.
[0125] As an optional implementation, the defocusing area 5 includes an inner defocusing area and an outer defocusing area. The inner defocusing area is arranged around the outside of the transition point diffusion area 2, and the outer defocusing area is arranged around the outside of the inner defocusing area. The diameter of the defocusing portion of the inner defocusing area is smaller than the diameter of the defocusing portion of the outer defocusing area.
[0126] The inner defocus area and the outer defocus area work together to achieve full defocus coverage, forming a larger defocus area with sufficient defocus signal, which can effectively ensure the defocus effect for myopia.
[0127] As an optional implementation, the inner defocus area includes a plurality of first defocus zones arranged sequentially from the inside to the outside. Each first defocus zone includes a plurality of first defocus portions 51 evenly distributed in the circumferential direction. The first defocus zone is configured as a circle or a regular hexagon, and the diameter of the first defocus portions 51 gradually increases from the inside to the outside.
[0128] The outer defocus area includes a plurality of second defocus zones arranged sequentially from the inside to the outside. Each second defocus zone includes a plurality of second defocus portions 52 evenly distributed circumferentially. The second defocus zone is configured as a circle or a regular hexagon, and all the second defocus portions 52 have the same diameter.
[0129] With this setting, the defocus degree of the defocus area 5 increases gradually from the inside out and then remains constant, which better matches the structural characteristics of the inner spherical retina of the eyeball. While ensuring the defocus effect, it also has the function of stabilizing the eye position. At the same time, the increase in defocus degree is small, and it is almost imperceptible to the eye when wearing the glasses, resulting in good wearing comfort.
[0130] Similar to Examples 3 to 10 above, the satellite point diffusion complex multi-point fogging multi-effect lens with defocus zone can also correct strabismus.
[0131] like Figure 6 As shown, Figure 6 Both the left region 13 and the right region 14 are provided with the dot diffusion area. 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, which can play a role in correcting esotropia.
[0132] Similar to Figure 6 The implementation shown can also correct exotropia, hypertropia, and hypotropia by setting the contrast between the left and right regions or the top and bottom regions.
[0133] like Figure 11 As shown, Figure 11 The right region 14 contains the dot diffusion area, and the left region 13 has a higher contrast than the right region 14. The light transmittance of the left region 13 is also higher than that of the right region 14, which can help correct esotropia.
[0134] Similar to Figure 6 The embodiment shown can also correct exotropia, hypertropia, and hypotropia by setting the point diffusion area in the left region 13, the upper region 11, and the lower region 12.
[0135] Example 12
[0136] The difference between Example 12 and any of the above examples is that:
[0137] The lens body 1 is configured as a convex lens, the defocusing part is configured as a groove or a protrusion, and the satellite point diffusion verification multi-point fogging multi-effect lens is a farsighted lens.
[0138] When the lens passes through the defocus zone 5, the defocused part refracts the light, causing the light to focus behind the retina, forming hyperopic defocus. Through image lag, it effectively stimulates the growth of the axial length of the eye, thereby inhibiting the progression of hyperopia.
[0139] Example 13
[0140] Example 13 is based on any of the above examples:
[0141] This utility model provides a pair of glasses, which includes the satellite point diffusion complex multi-point fogging multi-effect lens.
[0142] To further verify the visual impairment effect of this invention, refraction results were collected from 50 adolescents aged 7 to 17 with good visual function who wore the described satellite dot diffusion verification multi-point fogging multi-effect lens for approximately one year, as shown in the table below:

For example, right S-2.50C-0.50A176△8BI specifically means that the left eye's refraction result is myopia of 250 degrees, astigmatism of 50 degrees, astigmatic axis angle of 176 degrees, and exotropia of 8 prism diopters (△ represents prism diopters, and BI represents exotropia with the prism base facing inward). For example, right S+6.00C-1.00A90△3.5BO specifically means that the right eye's refraction result is hyperopia of 600 degrees, astigmatism of 100 degrees, astigmatic axis angle of 90 degrees, and esotropia of 3.5 prism diopters (△ represents prism diopters, BO represents esotropia with the prism base facing outward, and △0 represents normal).
[0151] As shown in the table above, among the 50 teenagers, only a small number experienced an increase in vision, and the increase was generally no more than 25 degrees. Most of them maintained their vision unchanged, and some even experienced a reduction in myopia, which was alleviated. In addition, a small number of esotropia patients wearing hyperopic negative defocus lenses experienced effective correction of their esotropia towards orthotropia through partial occlusion and optical stimulation with hyperopic negative defocus imaging lag. Their axial length increased faster than before without intervention, and their hyperopia decreased faster. Most exotropia patients were able to recover to a normal state by wearing custom-made multi-point defocus and point diffusion suppression interference combined with proper eye position training. This invention has a significant effect on inhibiting the deepening of vision, improving strabismus, and reducing hyperopia.
