Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a dynamic defocusing lens for left and right eye rotation and eyeglasses having the same. Background Technology

[0002] Left-right eye fusion: During normal vision, the human eyes fuse the images seen by the left and right eyes into a complete, three-dimensional image; this process is called image fusion. This technology, through special optical design, ensures that the left and right eyes can accurately fuse their respective images at different viewing distances and angles, providing the wearer with a clear and comfortable visual experience. It also helps improve the coordination between the two eyes and enhances visual stability.

[0003] Dynamic scattering: The lenses employ special materials and microstructure designs, resulting in dynamic scattering when light passes through them. This scattering is not random but dynamically adjusted based on factors such as the eye's gaze direction and viewing distance, causing the light to form a specific distribution on the retina, thereby achieving precise stimulation of the retina.

[0004] Defocus effect: By designing different optical zones on the lens, peripheral light is defocused in front of the retina, while the central zone ensures clear central vision. This defocus state can simulate the effect of orthokeratology lenses, inhibiting excessive elongation of the eye axis, thereby slowing down the progression of myopia. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a dynamic defocusing lens for left and right eye rotation and a frame eyeglass with the same lens.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a dynamic defocus lens for left and right eye rotation and a frame eyeglass with the same, including a lens, wherein the lens has a plurality of microlens protrusions distributed on it, the plurality of microlens protrusions being distributed in a multi-segment spiral shape and distributed in three layers: inner, middle and outer. The microlens protrusions distributed in the inner layer are the first defocus enhancement area, the microlens protrusions distributed in the middle layer are the second defocus enhancement area, and the microlens protrusions distributed in the outer layer are the third defocus enhancement area. A small optical zone is provided at the center of the lens.

[0008] The lens consists of a base layer, a blue light blocking layer, a polarizing layer, a wear-resistant layer, and a hydrophobic layer in sequence. One side of the base layer is covered with a blue light blocking layer, and the other side of the blue light blocking layer is covered with a polarizing layer. Both the other side of the polarizing layer and the other side of the base layer are covered with a wear-resistant layer, and the other side of the wear-resistant layer is coated with a hydrophobic layer.

[0009] Specifically, the diameter of the small optical area is 7.5 millimeters.

[0010] In detail, there are 12 spirally distributed microlens protrusions, and each spiral has 75 individual microlens protrusions, for a total of 900 microlens protrusions. The interval between adjacent microlens protrusions on any spiral line is 0.1 mm.

[0011] In detail, the refractive power intensity of the first defocus enhancement zone is 4.50D, the refractive power intensity of the second defocus enhancement zone is 4.00D, and the refractive power intensity of the third defocus enhancement zone is 3.50D.

[0012] In detail, the base layer is made of synthetic resin material.

[0013] In detail, the blue light blocking layer is made of blue light blocking film material.

[0014] In detail, the polarizing layer is made of polarizing film material.

[0015] In detail, the wear-resistant layer is made of a transparent polyurethane film material.

[0016] In detail, the hydrophobic layer is made of an organosilicon resin coating material.

[0017] In detail, a pair of glasses includes a frame and a nose pad fixed to the frame. A nose pad is fixed to the side of the frame facing the cheek, and ear pads are rotatably provided on both sides of the frame.

[0018] The design scheme proposed in this utility model has the following beneficial effects in application:

[0019] 1. Improved wearing comfort: The dynamic scattering characteristic makes the light propagation in the lens more uniform and softer, reducing adverse visual phenomena such as glare and halo. Wearers can feel a comfortable visual effect under different lighting conditions.

[0020] 2. Enhanced Myopia Control: Optimized left-right eye fusion and precise defocus design make this technology more effective in myopia control. It can more effectively stimulate peripheral retinal cells, regulate axial growth, and slow the progression of myopia.

[0021] 3. Personalized customization: The parameters of the lenses can be adjusted according to the wearer's age, degree of myopia, axial length, binocular vision function, etc., such as defocus, scattering degree, and optical area size, to meet the needs of different people.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-4 A dynamic defocusing lens for left and right eye rotation and eyeglasses with the same, comprising a lens 1, wherein a plurality of microlens protrusions are distributed on the lens 1, the plurality of microlens protrusions are distributed in a multi-segment spiral shape and are distributed in three layers: inner, middle and outer. The microlens protrusions distributed in the inner layer are the first defocusing enhancement area 12, the microlens protrusions distributed in the middle are the second defocusing enhancement area 13, and the microlens protrusions distributed in the outer layer are the third defocusing enhancement area 14. A small optical area 11 is provided at the center of the lens 1.

[0029] Central optical zone: The small optical zone is located in the central area of ​​the lens, typically with a diameter of about 6-8 mm. This area is primarily responsible for providing clear central vision, enabling the wearer to see distant objects clearly. Its refractive power matches the wearer's myopia prescription.

[0030] Small optical zone: By reducing the diameter of the lens's optical zone, a smaller central corneal treatment zone and a defocus ring closer to the pupil can be obtained, resulting in a steeper and wider peripheral myopic defocus, which can better control axial elongation. For children and adolescents whose myopia is progressing rapidly, the effect of slowing down myopia development may be more significant.

[0031] Small optical zone: mainly suitable for children and adolescents whose myopia progresses rapidly, especially younger people with greater potential for axial length growth, which can better leverage its advantages in myopia prevention and control;

[0032] Lens 1 consists of a base layer 1001, a blue light blocking layer 1002, a polarizing layer 1003, a wear-resistant layer 1004, and a hydrophobic layer 1005. One side of the base layer 1001 is covered with the blue light blocking layer 1002, and the other side of the blue light blocking layer 1002 is covered with the polarizing layer 1003. The other side of the polarizing layer 1003 and the other side of the base layer 1001 are both covered with the wear-resistant layer 1004, and the other side of the wear-resistant layer 1004 is coated with the hydrophobic layer 1005.

[0033] It should be further noted that the diameter of the small optical area 11 is 7.5 mm.

[0034] It should be further noted that there are 12 spirally distributed microlens protrusions, and each spiral has 75 individual microlens protrusions, for a total of 900 microlens protrusions. The interval between adjacent microlens protrusions on any spiral line is 0.1 mm.

[0035] It should be further noted that the refractive power intensity of the first defocus enhancement area 12 is 4.50D, the refractive power intensity of the second defocus enhancement area 13 is 4.00D, and the refractive power intensity of the third defocus enhancement area 14 is 3.50D.

[0036] It should be further noted that a frame 2 is fixed to the surface of the lens 1, a nose pad 21 is fixed to the side of the frame 2 facing the cheek, and ear pads 22 are respectively rotatably installed on both sides of the frame 2.

[0037] Defocus ring: Surrounding the small optical zone is a defocus ring formed by microlenses. Through special optical design, light forms a certain amount of defocus signal in front of the retina, thereby inhibiting excessive elongation of the eye axis and achieving the purpose of delaying the development of myopia.

[0038] The first defocus enhancement zone is 4.50D, the second defocus gradient zone is 4.00D, and the third defocus gradient zone is 3.50D. The zoned gradient defocus design is fully utilized to avoid defocus interference with static saturation.

[0039] Defocus intervention within a 50.10mm aperture range;

[0040] The 4.50D is the first defocus enhancement zone, and the first to third defocus gradient zones [+4.50D to +3.50D].

[0041] The study results indicate that, in order to sustainably slow down axial elongation, the applied myopic defocusing intervention should occur within a 20-degree field of view from the fovea. The best results are achieved when the applied myopic defocusing occurs within a 15-degree field of view from the fovea, as shown in the figure below:

[0042]

[0043] More dots = higher fill factor, this lens has a fill factor of up to 52%;

[0044] The fill factor is the ratio of the effective defocus area to the total design area within a specific region of a defocused lens. It reflects the degree to which the effective defocus area is utilized in the lens's design and is usually expressed as a percentage. The fill factor is calculated as: Fill Factor = (Effective Defocus Area / Total Design Area) × 100%.

[0045] The fill factor is closely related to the myopia control effect of defocus lenses. A higher fill factor means that there are more areas on the lens that can generate effective myopic defocus, thus acting more comprehensively on the peripheral retina, which may have a better inhibitory effect on axial elongation and thus enhance the myopia control effect.

[0046] It should be further noted that the base layer 1001 is made of synthetic resin material. Synthetic resin lenses have high impact resistance and are not easily broken, reducing the risk of injury caused by lens breakage. This is especially important for people engaged in sports or work. Synthetic resin lenses are generally much lighter than glass lenses, making them more comfortable to wear and reducing pressure on the bridge of the nose and ears.

[0047] It should be further explained that the blue light blocking layer 1002 is made of blue light blocking film material. Prolonged use of electronic devices (such as computers, mobile phones and tablets) can lead to eye fatigue, dryness and discomfort. The blue light blocking film can filter some harmful blue light, reduce the burden on the eyes, and improve visual comfort. The blue light blocking film can reduce the effect of blue light on melatonin, help improve sleep quality. In addition to filtering blue light, the blue light blocking film can also reduce glare and reflection, improve visual clarity and contrast, and make the field of vision clearer and more comfortable.

[0048] It should be further noted that the polarizing layer 1003 is made of polarizing film material. Polarizing film can effectively filter reflected light from horizontal surfaces (such as water, snow and roads), reduce glare, and improve visual comfort and clarity. By filtering unnecessary reflected light, polarizing film can make the field of vision clearer and sharper, especially in strong light environments, such as places with direct sunlight or strong reflection.

[0049] It should be further noted that the wear-resistant layer 1004 is made of transparent polyurethane film material. Transparent polyurethane has excellent light transmittance, reaching more than 90%, and is suitable for optical lenses, displays and other applications that require high transparency. Transparent polyurethane has high strength, high elasticity and good wear resistance, and can withstand greater impact and pressure.

[0050] It should be further noted that the hydrophobic layer 1005 is made of silicone resin coating material. The silicone resin coating has good hydrophobicity, which can reduce the adhesion of water droplets on the surface and improve the waterproofness and easy cleaning of the product. The silicone resin coating has excellent heat resistance and can maintain stable performance in high temperature environments. The silicone resin coating has excellent chemical resistance and can resist the corrosion of most organic solvents, acids, alkalis and oils.

[0051] The advantages of this invention are: improved wearing comfort: the dynamic scattering characteristics make the light propagation in the lens more uniform and softer, reducing adverse visual phenomena such as glare and halo, and the wearer can feel a comfortable visual effect under different lighting conditions.

[0052] Enhanced myopia control: Optimized left-right eye fusion and precise defocus design make this technology more effective in myopia control. It can more effectively stimulate peripheral retinal cells, regulate axial growth, and slow the progression of myopia.

[0053] Personalized customization: The parameters of the lenses can be adjusted according to the wearer's age, degree of myopia, axial length, binocular vision function, etc., such as defocus, scattering degree, and optical area size, to meet the needs of different people.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
