Description

Technical Field

[0001] This utility model belongs to the field of optical device technology, and specifically relates to a lens assembly and eyeglasses. Background Technology

[0002] In the field of adolescent vision health, amblyopia is a common visual developmental disorder. With the increase in close-range eye use and the higher frequency of electronic screen use among adolescents in modern society, the incidence of amblyopia is showing a steady upward trend.

[0003] Currently, the main methods for correcting amblyopia in adolescents fall into three categories: optical correction, occlusion therapy, and vision training. Optical correction, as a basic approach, adjusts the refractive state by wearing eyeglasses (such as single-vision or astigmatic lenses) to provide clear imaging of the retina. However, it only addresses the basic refractive error and cannot target the core mechanisms of amblyopia. Occlusion therapy forces the use of the amblyopic eye by covering the healthy eye, breaking the brain's inhibition of the amblyopic eye. However, it suffers from problems such as difficulty in precisely controlling the occlusion time (too long can lead to decreased vision in the healthy eye, while too short a time is insufficient), poor compliance among adolescents (due to appearance affecting social interaction), and lack of binocular vision coordination training. Vision training uses specific visual tasks (such as tracing or amblyopia training software) to exercise the visual function of the amblyopic eye. However, this method requires specialized equipment and continuous supervision, and its effectiveness is easily affected by individual cooperation and training intensity, making it difficult to develop standardized and universally applicable intervention programs.

[0004] In summary, the current field of amblyopia correction for adolescents urgently needs an optical correction device that can simultaneously address refractive correction, binocular vision activation, and personalized adaptation requirements. Through innovative lens structure design, this device could solve the technical pain points of existing technologies, such as "primarily monocular intervention with insufficient binocular coordination," "limited microstructural function and stimulation intensity," and "poor adaptability, unable to meet diverse refractive and amblyopia types." This would provide adolescent amblyopia patients with a more efficient, convenient, and easily adhered-to correction solution, thereby improving the overall efficacy of amblyopia intervention and reducing the negative impact of visual developmental abnormalities on the healthy growth of adolescents. Utility Model Content

[0005] This utility model is proposed based on the above-mentioned needs of the prior art. The technical problem to be solved by this utility model is to provide a lens assembly and glasses to improve amblyopia.

[0006] To solve the above problems, the technical solution provided by this utility model includes:

[0007] A lens assembly is provided, comprising: a first lens for the left eye, wherein the first lens has a plurality of first preset regions; and a second lens for the right eye, wherein the second lens has a plurality of second preset regions; when the first lens and the second lens overlap, the edge of the projection of the first preset region onto the preset surface in a preset direction is connected to or spaced from the edge of the projection of the second preset region onto the preset surface in the preset direction; the first preset regions and the second preset regions are shadow regions with light transmittance, or microlenses are provided in the first preset regions and the second preset regions, and when the image is formed in the human eye through the first lens and the second lens, different regions of the image have different contrasts.

[0008] Preferably, the preset direction is perpendicular to the preset surface.

[0009] Preferably, a microlens is provided in the first preset area and within the first preset area, and the optical power of the microlens gradually increases from the center of the lens in a radial direction outward; the optical power of the microlens is +1D to +5.5D.

[0010] Preferably, the first preset area is located outside the central field of view; the second preset area is located outside the central field of view.

[0011] Preferably, the first preset area and the second preset area are shadow areas with light transmittance. The shadow areas on the first lens have the same light transmittance, the shadow areas on the second lens have the same light transmittance, and the light transmittance of the first shadow area and the second shadow area are different.

[0012] Preferably, the plurality of first preset regions on the first lens are in the form of a constant-speed spiral, and the plurality of second preset regions on the second lens are in the form of a constant-speed spiral.

[0013] Preferably, the centers of the plurality of first preset regions are all on a first constant-velocity spiral line, and the centers of the plurality of second preset regions are all on a second constant-velocity spiral line; the first constant-velocity spiral line is represented as: Where α represents the distance between the starting point and the origin, β represents the pitch of the helix, θ is the helix angle, the origin is the center of the constant velocity helix, and x1 and y1 are the horizontal and vertical coordinates; the second constant velocity helix is ​​represented as: Where x2 and y2 are the horizontal and vertical coordinates.

[0014] Preferably, the first lens has a plurality of concentrically arranged annular regions, and the second lens has a plurality of concentrically arranged annular regions. The annular regions on the first lens and the annular regions on the second lens have the same inner diameter, outer diameter, and ring width. The first preset region and the second preset region are located within the annular regions, and their edges are connected to the inner and outer rings of the annular regions. The projections of the first preset region and the second preset region on the projection surface are still within the annular region of the projection.

[0015] Preferably, the projections of the first preset region and the second region onto the projection surface form concentric rings.

[0016] The invention also provides eyeglasses, including: a frame, any one lens group, and a first lens and a second lens disposed on the frame.

[0017] Compared with existing technologies, this invention sets microlenses in the preset areas of the first and second lenses, or sets the preset areas as shadow areas with a certain degree of light transmittance, so that the preset areas on the first and second areas are complementary, that is, the projections of the two are connected to each other or have gaps, allowing the two eyes to receive refined visual signals from different spatial areas. When the brain processes these complementary signals, it needs to actively integrate the information from both eyes to form a complete visual image, thereby breaking the inhibition of the amblyopic eye and forcibly activating the coordinated operation of binocular vision. Compared with the traditional occlusion therapy mode of "single strengthening of the amblyopic eye and ignoring binocular coordination", this design can simultaneously improve the visual acuity of the amblyopic eye and binocular vision function (such as fusion function and stereopsis), avoiding the problem of fluctuations in the visual acuity of the healthy eye and the disconnection of binocular vision function that may be caused by occlusion. The regular arrangement of preset area arrays and the gradual change in optical parameters can create an imaging effect of "clear center and gradual peripheral gradation" on the retina. This regular refractive difference can moderately stimulate retinal photoreceptor cells and visual neural pathways, promoting the development and maturation of visual function in amblyopic eyes. It is especially suitable for patients with amblyopia caused by form deprivation, making up for the shortcomings of traditional visual training that "relies on subjective cooperation and is difficult to quantify stimulation intensity." This design can enhance the contrast and recognition of visual signals through differentiated distribution of light intensity, making it easier for the brain to capture the visual information input from the amblyopic eye, while avoiding damage to the retina from strong light. It is suitable for amblyopic patients who are sensitive to light or have weak visual contrast perception, expanding the applicable scenarios of the correction program. Attached Figure Description

It is understood that the device is multifunctional and independent of its spatial orientation.

[0031] To facilitate understanding of the embodiments of this utility model, 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 utility model.

[0032] Example 1

[0033] This embodiment provides a lens assembly, such as Figures 1-7 As shown.

[0034] The lens group includes a first lens 1 and a second lens 2. Further, the first lens 1 and the second lens 2 have a base power ranging from -10D to +1D.

[0035] Both the first lens 1 and the second lens 2 have preset areas, and the preset area on the first lens 1 is complementary to the second preset area 5 on the second lens 2. The preset portion is located outside the central field of view 10, which has a range of 0° to 30°.

[0036] Specifically, the first lens 1 has multiple first preset regions 4, and the second lens 2 has multiple second preset regions 5. When the first lens 1 and the second lens 2 coincide in a preset direction, the edge of the projection of the first preset region 4 onto the preset surface in the preset direction is connected to or spaced from the edge of the projection of the second preset region 5 onto the preset surface in the preset direction. Specifically, the plane containing the first lens 1, the plane containing the second lens 2, and the preset surface are parallel, and the first lens 1 and the second lens 2 coincide in a preset direction, which is the normal direction of the preset surface. This ensures that when the first lens 1 and the second lens 2 are in the aforementioned overlapping state, the multiple first preset regions 4 projected by the first lens 1 onto the preset surface and the multiple second preset regions 5 projected by the second lens 2 onto the preset surface are independent of each other, that is, the projections of the first preset regions 4 and the second preset regions 5 onto the preset surface have no overlapping portions.

[0037] The arrangement of the first preset regions 4 on the first lens 1 includes, but is not limited to: adjacent first preset regions 4 being connected to each other; or adjacent first preset regions 4 being spaced apart from each other; or as follows: Figure 7 As shown, multiple first preset regions 4 are grouped together, and the multiple first preset regions 4 within each group are connected, with a certain interval between each group. The arrangement of the second preset regions 5 on the second lens 2 is similar to the arrangement of the first preset regions 4 on the first lens 1.

[0038] A first microlens 6 is disposed within a first preset region 4, or the first preset region 4 is a first shadow region 8 with a certain degree of light transmittance. Correspondingly, a second microlens 7 is disposed within a second preset region 5, or the second preset region 5 is a second shadow region 9 with a certain degree of light transmittance.

[0039] Furthermore, when the first lens 1 is provided with a first microlens 6, the second lens 2 is provided with a second microlens 7; when the first lens 1 is provided with a first shadow area 8, the second lens 2 is provided with a second shadow area 9.

[0040] When microlenses are placed in corresponding preset areas on both the first lens 1 and the second lens 2, the microlenses at different positions have different optical powers. The optical power gradually increases radially outward from the center; that is, the optical power of the microlenses closer to the center of the lens is smaller, and the optical power of the microlenses farther from the center gradually increases with distance. Specifically, the optical power range of the first microlens 6 and the second microlens 7 is +1D to +5.5D. This gradual transition provides a smoother viewing experience for the viewer. Alternatively, the microlenses on the first lens 1 have the same optical power, the microlenses on the second lens 2 have the same optical power, and the optical powers of the first microlens 6 and the second microlens 7 are different.

[0041] When the shadow areas are set in corresponding preset areas on both the first lens 1 and the second lens 2, the shadow areas at different positions have different light transmittance. The light transmittance gradually decreases from the center outwards, meaning that the shadow area closer to the center of the lens has higher light transmittance, while the light transmittance of the shadow area farther from the center gradually decreases with distance. Or, as... Figure 5 and Figure 6 As shown, the shadow areas on the first lens 1 have the same light transmittance, the shadow areas on the second lens 2 have the same optical power, and the optical power of the first shadow area 8 and the second shadow area 9 are different.

[0042] The first lens 1 and the second lens 2 correspond to the left and right eyes of the human eye, respectively. The left and right eyes of the human eye form a composite visual field after passing through the first lens 1 and the second lens 2, respectively. After light passes through the first lens 1 and the second lens 2 and the microlenses or light-transmitting shadow areas set on them, an image is formed in the human eye. Different areas of the image have different contrasts. By changing the contrast of the image entering the eye, the treatment of amblyopia can be assisted.

[0043] Furthermore, the plurality of first preset regions 4 on the first lens 1 are arranged in a regular pattern, and the plurality of second preset regions 5 on the second lens 2 are arranged in a regular pattern.

[0044] In one feasible implementation of this embodiment, such as Figure 1 As shown, multiple first preset regions 4 form a constant-velocity spiral on the first lens 1, and multiple second preset regions 5 form a constant-velocity spiral on the second lens 2. Specifically, the centers of the multiple first preset regions 4 are all on the first constant-velocity spiral, and correspondingly, the centers of the multiple second preset regions 5 are all on the second constant-velocity spiral. The first constant-velocity spiral is represented as follows:

[0045]

[0046] Where α represents the distance between the starting point and the origin, β represents the pitch of the helix, θ is the helix angle, the origin is the center of the constant velocity helix, and x1 and y1 are the horizontal and vertical coordinates.

[0047] The second constant velocity spiral is represented as:

[0048]

[0049] Where x2 and y2 are the horizontal and vertical coordinates.

[0050] By setting the array formed by the preset regions on the first lens 1 and the second lens 2, the first preset region 4 and the second preset region 5 can be made complementary on the preset surface.

[0051] Furthermore, such as Figure 1 As shown, adjacent first preset regions 4 are connected, and adjacent second preset regions 5 are connected. When a first microlens 6 is provided in the first preset region 4 and a second microlens 7 is provided in the second preset region 5, adjacent first microlenses 6 are tangent, and adjacent second microlenses 7 are tangent.

[0052] Furthermore, the first lens 1 has multiple concentrically arranged annular regions, and the second lens 2 has multiple concentrically arranged annular regions. The annular regions on the first lens 1 and the second lens 2 have the same inner diameter, outer diameter, and ring width. The first preset region 4 and the second preset region 5 are located within the annular regions, and their edges are connected to the inner and outer rings of the annular regions. The projections of the first preset region 4 and the second preset region 5 on the projection surface 3 are still within the annular region of the projection.

[0053] The first lens 1 has multiple concentrically arranged annular regions, each annular region having at least one first preset region 4 occupying a portion of the annular region. Similarly, the second lens 2 has multiple concentrically arranged annular regions, each annular region having at least one second preset region 5 occupying a portion of the annular region. The annular regions on the first lens 1 and the corresponding annular regions on the second lens 2 have the same inner and outer radii, such that the first preset region 4 on the first lens 1 and the corresponding second preset region 5 on the second lens 2 are located in the same annular region. Furthermore, the first preset region 4 and the second preset region 5 form multiple concentric annular regions.

[0054] In one feasible implementation of this embodiment, such as Figure 4As shown, multiple annular regions are divided into multiple parts radially, forming a fan-shaped section between two adjacent radii used for radial division. This section is further divided into multiple sub-sections by the annular regions, with preset regions spaced at intervals within these sub-sections. Specifically, the sub-sections of the first preset region 4 and the second preset region 5 are complementary, causing their projections on the projection plane 3 to form multiple concentric annular rings, as shown... Figure 3 As shown.

[0055] In another feasible implementation of this embodiment, such as Figure 2 As shown, each ring is divided into multiple arc-shaped regions, and the number of arc-shaped regions in each ring is the same. Adjacent preset regions are set in the arc-shaped regions at intervals. The preset regions on adjacent rings are staggered, so that the lens has multiple constant-speed spiral curves formed by the preset regions that extend from the center of the lens to the edge of the lens.

[0056] Example 2

[0057] This embodiment provides a pair of eyeglasses.

[0058] The eyeglasses include a frame and the lens assembly as described in Embodiment 1, wherein the first lens 1 and the second lens 2 are disposed on the frame and correspond to the left and right eyes, respectively.

[0059] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
