Description

Technical Field

[0001] This utility model relates to a defocus composite lens for fogging and eyeglasses with the same, belonging to the field of defocus lenses. Background Technology

[0002] Defocus lenses are specially designed eyeglass lenses intended to help improve vision problems by changing the focus of vision, especially in cases of eye strain and decreased vision caused by excessive close-up work. In recent years, with the widespread use of electronic devices, more and more people are experiencing vision problems such as myopia, hyperopia, and astigmatism. Traditional eyeglasses often rely on direct correction of vision, but defocus lenses, by creating a blurred visual effect, can slow the progression of myopia to some extent and improve eye comfort.

[0003] Regarding the aforementioned existing technologies, the inventors discovered that the effectiveness of existing defocus lenses in visual correction varies from person to person. While some studies show that they have a positive effect on slowing the progression of myopia, other studies indicate that their effect is not significant. Therefore, for some patients with eye diseases or those with more severe vision problems, the effect of defocus lenses may not meet expectations, and traditional vision correction solutions are still necessary. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a fog-viewing defocusing composite lens.

[0005] The fog-viewing defocusing composite lens provided in this application adopts the following technical solution:

[0006] A fog-viewing defocusing composite lens includes:

[0007] Lens substrate;

[0008] Multiple sets of defocused microlenses are nested sequentially from the inside out on one side of the lens substrate.

[0009] Multiple sets of annular fogging defocus areas are provided on the surface of the other side of the lens substrate, and the orthographic projection of each set of annular fogging defocus areas is located between the two connected sets of defocus microlenses.

[0010] Through the aforementioned technical solution, this application optimizes the lens structure and controls light scattering using a fogging defocusing technology. By precisely arranging microlenses on the lens surface to form a specific optical structure, a "defocused" effect can be created in the visual experience. This effect means that when observing at close and far distances, the light received by the retina is no longer sharp, but rather a softly scattered, blurred light and shadow. This blurred visual information can effectively reduce the eye's sensitivity to high-contrast scenes, thereby reducing the eye's accommodative burden and delaying the onset of visual fatigue.

[0011] Building upon this foundation, this application further incorporates multiple sets of annular fogging defocus areas, resulting in thousands of light-scattering micro-points on the lens from its edge to its center. These micro-points gently scatter light before it reaches the retina, reducing visual contrast at various distances. This design not only enhances visual comfort but also reduces eye strain to some extent. By reducing the retina's response to high-contrast signals, fogging defocus technology effectively reduces the "elongation" signals sent from the eye to the brain, thereby slowing axial elongation and serving as an effective means of controlling myopia progression. The light-scattering design reduces visual stress and eye comfort during prolonged close-range use of the eyes (such as using computers or mobile phones), minimizing common eye fatigue and dryness.

[0012] Furthermore, the multiple sets of defocused microlens groups are provided with 5-12 rings.

[0013] Furthermore, the multiple sets of annular fog defocus zones are provided with 6-13 rings.

[0014] Furthermore, each group of annular fog defocusing areas is provided with multiple fog viewpoints, the bandwidth of each group of annular fog defocusing areas is 0.6-1.0mm, and the distance between two adjacent groups of annular fog defocusing areas is 1.0-1.2mm.

[0015] Furthermore, each of the aforementioned fog viewpoints has a diameter of 0.1 mm, and the fog density of each group of the annular fog defocus zone is 5%-10%.

[0016] Furthermore, the defocusing amount of each defocused microlens group is 3.50 to 4.50D.

[0017] Furthermore, the multiple sets of defocused microlens groups are provided with 12 rings, and the number of microlenses provided in the multiple sets of defocused microlens groups is 852.

[0018] The technical solution of this application can be customized according to the retinal characteristics of users of different ages, especially teenagers and children. This personalized adaptation enables each user to obtain the best visual experience and ensures the most comfortable effect during use.

[0019] Furthermore, this application's technical solution further optimizes the structure by embedding 852 microlenses in each lens, forming a 12-ring microlens array. These microlenses not only provide effective scattering but also ensure the continuity of the defocus zone. This design adapts to the curvature of the retina, making the defocus signal more closely match the natural shape of the eyeball.

[0020] Secondly, this application provides a framed eyeglasses solution using the following technical solution:

[0021] A type of eyeglass includes the fog-viewing defocusing composite lens described in any of the above claims.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application optimizes the lens structure by controlling light scattering through a defocusing fogging technology. By precisely arranging microlenses on the lens surface to form a specific optical structure, a "defocused" effect can be created in the visual experience. This effect means that when observing at close and far distances, the light received by the retina is no longer sharp, but rather a softly scattered, blurred light and shadow. This blurred visual information can effectively reduce the eye's sensitivity to high-contrast scenes, thereby reducing the eye's accommodative burden and delaying the onset of visual fatigue.

[0024] 2. This application further incorporates multiple sets of annular fogging defocus areas, resulting in thousands of light-scattering micro-points from the edge to the center of the lens. These micro-points gently scatter light before it reaches the retina, reducing visual contrast at various distances. This design not only improves visual comfort but also reduces eye strain to some extent. By reducing the retina's response to high-contrast signals, fogging defocus technology effectively reduces the "elongation" signals sent from the eye to the brain, thereby slowing the growth of the eye axis and serving as an effective means of controlling myopia progression. The light-scattering design reduces visual stress and eye comfort during prolonged close-range use of the eyes (such as using a computer or mobile phone), reducing common eye fatigue and dryness.

[0025] 3. The technical solution of this application further optimizes the structure by embedding 852 microlenses in each lens, forming a 12-ring microlens array. These microlenses not only provide effective scattering but also ensure the continuity of the defocus zone. This design adapts to the curvature of the retina, making the defocus signal more closely match the natural shape of the eyeball. Attached Figure Description
