Description

Technical Field

[0001] The utility model relates to the technical field of myopia lenses, in particular to a point diffusion spectacle lens. Background Art

[0002] Myopia is a common vision problem, mainly caused by an excessively long eye axis or an overly strong refractive power of the lens, which causes the image of distant objects to fall in front of the retina, making the patient's view of distant objects blurry. In order to correct myopia, people usually wear myopia lenses. Myopia lenses mainly have concave lenses, which diverge light so that the image of distant objects can accurately fall on the retina, thereby improving vision. Traditional myopia lenses mainly focus on the function of correcting vision, that is, allowing patients to see objects clearly. However, as people conduct in-depth research on the problem of myopia, it is found that simply correcting vision cannot completely solve the problem of myopia development. Especially among adolescents, the incidence of myopia is constantly increasing, and the degree of myopia is also constantly deepening, which brings great troubles to patients' lives and studies.

[0003] In the current myopia lens market, most products focus on providing clear vision correction, but the effect of delaying the progression of myopia is not ideal. In real life scenarios, for example, students' eyes are constantly exposed to various light stimuli during a long period of study. Traditional myopia lenses cannot effectively control the gain of light. The front cells easily detect high-gain signals and send elongation signals to the eyes, which causes the eye axis to continue to grow, resulting in a gradual deepening of myopia. For example, in the daily use of electronic devices, the light intensity emitted by the screen is high, and traditional lenses cannot well alleviate this light, causing the eyes to be exposed to high-intensity light stimulation for a long time, further aggravating the development of myopia. In addition, some existing myopia lenses are relatively simple in functional design, and do not fully consider the physiological characteristics of the eyes and the mechanism of myopia development, and cannot fundamentally solve the problem of deepening myopia. Therefore, the technology in this field proposes a point diffusion lens to solve the above problems. Utility Model Content

[0004] In order to make up for the above deficiencies, the present invention provides a point diffusion spectacle lens, which aims to improve the problem in the prior art that myopia lenses may cause the user's myopia to worsen seriously when worn for a long time.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a point diffusion spectacle lens comprising a lens body, a dispersion reduction component, and an anti-fogging component, wherein the dispersion reduction component is disposed inside the lens body, and the anti-fogging components are disposed on both sides of the exterior of the lens body; a central area is disposed at the center of the lens body, a functional area is disposed between the lens body and the central area, and an auxiliary component is disposed inside the lens body, the auxiliary component being used to prevent worsening myopia of the user;

[0006] The auxiliary component includes a transparent lens, which is arranged at the inner center of a lens body. A plurality of light diffusion points are evenly arranged inside the lens body.

[0007] Furthermore, the transparent lens is located at the center area, and the functional area where multiple light diffusion points are evenly distributed.

[0008] Furthermore, the lens body is made of PC material or 1.67 resin raw material, and the thickness of the lens body at the center is 1 to 8 mm.

[0009] Furthermore, the dispersion reduction component includes a plurality of fluorite particles, and the plurality of fluorite particles are evenly distributed inside the lens body.

[0010] Furthermore, the anti-fogging component includes a light-transmitting film and a hydrophilic film, wherein the light-transmitting film is arranged on the outside of the lens body, and the hydrophilic film is arranged on the outside of the light-transmitting film.

[0011] Furthermore, the material of the light-transmitting film is a double-sided anti-reflection film or a high-transmittance and high-cleanliness UV film, and the material of the hydrophilic film is a polyvinyl alcohol film.

[0012] The utility model has the following beneficial effects:

[0013] 1. In the present invention, a central area is reserved at the optical center of the lens body for correction, and all peripheral functional areas are artificially fluorescent lighted using point diffusion technology to make them defocused and unable to form images. By reducing the gain through the use of moderate light, the high-gain signal detected by the front cells and the elongation signal sent to the eye are reduced, thereby delaying the growth of the eye axis and delaying the progression of myopia.

[0014] 2. In the present invention, a polyvinyl alcohol film is plated on the lens body. The hydroxyl groups on the molecular chains of the polyvinyl alcohol can attract water molecules. When water vapor contacts the surface of the lens body, the water vapor will be quickly adsorbed by the hydroxyl groups and spread out to form a uniform water film instead of existing in the form of small water droplets. This can prevent light from being refracted and scattered on the surface of the small water droplets, thereby achieving a good anti-fog effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 3 The utility model provides an embodiment: a point diffusion eyeglass lens, comprising a lens body 1, a dispersion reduction component and an anti-fogging component, the dispersion reduction component is arranged inside the lens body 1, the anti-fogging components are arranged on both sides of the outside of the lens body 1, a central area 2 is arranged at the center of the lens body 1, a functional area 4 is arranged between the lens body 1 and the central area 2, the interior of the functional area 4 is used to evenly distribute a large number of light diffusion points 5, an auxiliary component is arranged inside the lens body 1, and the auxiliary component is used to prevent the user's myopia from worsening; the auxiliary component includes a transparent lens 3, the transparent lens 3 is arranged at the inner center of the lens body 1, and the lens A plurality of light diffusion points 5 are evenly arranged inside the lens body 1, the transparent lens 3 is located in the central area 2, there are no light diffusion points 5 in the transparent lens 3, and a plurality of light diffusion points 5 are evenly distributed in the functional area 4. The material of the lens body 1 is PC material or 1.67 resin raw material. The thickness at the center of the lens body 1 is 1 to 8 mm. The user selects a lens of appropriate thickness. The dispersion reduction component includes a plurality of fluorite particles 6, and the plurality of fluorite particles 6 are evenly distributed inside the lens body 1. The atomic structure and chemical bond characteristics of the fluorite material make it have a small difference in the refraction of light of different colors, thereby reducing the dispersion phenomenon.

[0022] Specifically, the lens body 1 of version 2.0 is made of PC, while the lens body 1 of version 3.0 is made of 1.67 resin. A central zone 2 is intentionally reserved at the optical center of the lens body 1. This central zone 2 is primarily used for vision correction. Its working principle is to ensure that light is accurately focused on the retina through precise optical design, allowing the user to clearly see objects both near and far. Between the lens body 1 and the central zone 2 is a functional zone 4. This functional zone 4 utilizes point diffusion technology. This technology artificially scatters light, causing it to be out of focus and thus obscure the image. This effectively moderates the intensity of light as it passes through the functional zone 4. This moderated light reduces the gain effect. In the physiological mechanism of the eye, the prefrontal cortex detects the gain signal of light. When the gain signal is too high, it signals the eye to elongate, thereby increasing the eye's axial length. Excessive axial length growth is one of the main causes of progressive myopia. By reducing the gain signal through point diffusion technology, the high-gain signal detected by the anterior cells and the elongation signal sent to the eye can be reduced, thereby effectively delaying the growth of the eye axis and ultimately achieving the goal of delaying the progression of myopia.

[0023] Reference Figure 1-Figure 3 The anti-fogging component includes a light-transmitting film 7 and a hydrophilic film 8. The light-transmitting film 7 is arranged on the outside of the lens body 1, and the hydrophilic film 8 is arranged on the outside of the light-transmitting film 7. The material of the light-transmitting film 7 is a double-sided anti-reflection film or a high-transmittance and high-cleanliness UV film. The material of the hydrophilic film 8 is a polyvinyl alcohol film. The molecular chain in the hydrophilic film 8 contains a large number of hydroxyl groups. These hydroxyl groups can strongly attract water molecules. When water vapor comes into contact with the surface of the lens body 1, it will be adsorbed by the hydroxyl groups and then spread out on the entire surface of the lens body 1 to form a uniform water film instead of small water droplets, thereby achieving an anti-fogging effect.

[0024] Specifically, the transparent film 7 in version 2.0 is made of a double-sided antireflection coating, while the transparent film 7 in version 3.0 is made of a high-transmittance, high-purity UV film. Anti-fogging components are installed on both sides of the exterior of the lens body 1. The hydrophilic film 8 contains a large number of hydroxyl groups in its molecular chains. These hydroxyl groups have a strong ability to attract water molecules. When water vapor comes into contact with the surface of the lens body 1, the water vapor is rapidly adsorbed by the hydroxyl groups. The adsorbed water molecules then spread across the entire surface of the lens body 1, forming a uniform water film rather than small water droplets. This state prevents light from being refracted and scattered by the surface of the small water droplets, thereby achieving an excellent anti-fog effect. Furthermore, multiple fluorite particles 6 are evenly distributed within the interior of the lens body 1. These fluorite particles 6 have unique optical properties that effectively reduce dispersion. When light passes through a lens, light of different wavelengths disperses due to differences in refractive index, resulting in undesirable effects such as color fringing in the image. The presence of fluorite particles 6 can reduce the refractive index difference of light of different wavelengths, allowing the light to be focused more accurately, thereby improving image clarity and color accuracy, making the user's wearing experience more comfortable and high-quality.

[0025] Working principle: A central area 2 is left in the optical center of the lens body 1 for correction, and the peripheral functional areas 4 are all artificially fluorescent light using point diffusion technology to make them defocused and unable to form images. The gain is reduced by softening the light, reducing the high-gain signal detected by the front cells and the elongation signal sent to the eyes, thereby delaying the growth of the eye axis and delaying the progression of myopia. In addition, the molecular chain in the hydrophilic film 8 contains a large number of hydroxyl groups, which can strongly attract water molecules. When the surface of the lens body 1 is exposed to water vapor, it will be adsorbed by the hydroxyl groups and then spread over the entire surface of the lens body 1 to form a uniform water film instead of small water droplets, thereby achieving an anti-fog effect. Moreover, the fluorite particles 6 inside the lens body 1 can reduce dispersion, making the user's wearing experience better.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
