Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, and more specifically, to a pair of magnetic eyeglasses for both near and far vision. Background Technology

[0002] As my country's population ages, the number of people with presbyopia continues to rise, with a large number of middle-aged and elderly people suffering from combined refractive errors of myopia and presbyopia. These individuals need to correct myopia in their daily lives while facing insufficient accommodation for close-range activities such as reading, writing, and using mobile phones. Therefore, they require an optical correction solution that balances near and far vision, is convenient to use, and is cost-effective.

[0003] Currently, the mainstream solutions for people with both myopia and presbyopia mainly include progressive multifocal lenses, bifocal lenses, and wearing two separate pairs of glasses—one for myopia and one for presbyopia—to alternate between. However, these traditional technologies generally have many limitations in practical applications and are difficult to meet the comprehensive needs of modern users for functionality, comfort, aesthetics, and convenience.

[0004] First, while progressive multifocal lenses achieve comprehensive vision coverage at multiple distances (far, intermediate, and near) with a single pair of glasses, they are expensive, have a complex fitting process, and require a long adaptation period. Many users experience discomfort such as dizziness, unsteady gait, blurred peripheral vision, and a swimming effect when moving their gaze, severely impacting their user experience. Furthermore, if the lenses are damaged or the prescription changes, the entire lens needs to be replaced, resulting in high maintenance costs.

[0005] Secondly, while bifocal lenses are less expensive, they have a noticeable dividing line, affecting their aesthetics. Furthermore, the transition at mid-range distances is unnatural, creating a visual jump and resulting in a poor user experience. Additionally, their fixed optical area cannot be flexibly adjusted, making it difficult to meet the needs of diverse visual scenarios.

[0006] Secondly, while alternating between two pairs of glasses is simple to operate, it is extremely inconvenient to use. Users need to frequently take off and put on their glasses, which is not only inefficient but also prone to causing frame deformation, lens scratches, and even affecting daily life and work efficiency when the corresponding glasses cannot be found when immediate reading is needed. In addition, carrying two pairs of glasses also increases the risk of loss or damage. Therefore, a dual-lens magnetic glasses for near and far vision is proposed. Utility Model Content

[0007] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: a pair of magnetically attached near-vision and far-vision glasses, comprising a pair for mounting near-vision lenses and a main frame, wherein the outer edge of the main frame is provided with a first magnetic component; and a pair of foldable magnetically attached reading glasses, wherein the magnetically attached reading glasses include a pair of reading lenses with positive refractive power, a folding nose pad assembly connecting the two lenses, and a second magnetic component disposed on the outer side of the attachment; the first magnetic component and the second magnetic component magnetically cooperate, allowing the magnetically attached reading glasses attachment to the front of the main frame, achieving optical superposition of the reading lenses and the near-vision lenses, which is particularly suitable for near-vision.

[0008] As a preferred technical solution of this utility model, the reading lens adopts a concave structure, that is, the outer surface of the lens is a flat or slightly convex surface, and the inner surface is a concave surface, which reduces the overall thickness of the lens and maintains a gap between it and the myopia lens of the main frame in the adsorption state to avoid physical contact.

[0009] As a preferred technical solution of this utility model, the refractive power of the reading lenses is from +1.00D to +3.00D, specifically including at least one of +1.00D, +1.50D, +2.00D, +2.50D and +3.00D. Users can replace the matching magnetic lenses according to their own degree of presbyopia.

[0010] As a preferred technical solution of this utility model, the folding nose pad assembly includes a left nose pad arm and a right nose pad arm connected by a hinge. The left nose pad arm and the right nose pad arm can rotate relative to each other around the hinge to achieve folding from 0° to 180°, so that the magnetic lens of the reading glasses can be folded in half and stored when not in use.

[0011] As a preferred technical solution of this utility model, the ends of the left and right nose support arms are provided with soft nose pads, which are made of silicone or TPE material to improve wearing comfort.

[0012] As a preferred technical solution of this utility model, the first magnetic component is a plurality of permanent magnets or ferromagnetic blocks embedded on the outside of the main frame, and the second magnetic component is a different type of permanent magnet set at the corresponding position of the magnetic sleeve of the reading glasses. After magnetic attraction, automatic alignment and stable fixation are achieved.

[0013] As a preferred technical solution of this utility model, the lens edge of the magnetic reading glasses is provided with a lightweight plastic or flexible silicone frame. The frame covers the lens edge and integrates a second magnetic component to enhance the structural strength and magnetic adhesion stability.

[0014] As a preferred technical solution of this utility model, the main frame is a full-frame, half-frame, or frameless structure, and the material is selected from one of titanium alloy, TR90, sheet metal, or metal alloy, and is compatible with commercially available conventional myopia frames.

[0015] As a preferred technical solution of this utility model, the overall weight of the magnetic reading glasses sleeve does not exceed 10 grams, and the thickness after folding is less than 15 millimeters, making it easy to carry around.

[0016] As a preferred technical solution of this utility model, the user can achieve near vision mode by magnetically attaching the reading glasses to the main frame, and restore the distance vision mode after removing the lenses, thus achieving rapid switching between near and distance vision without the need to wear two pairs of glasses or use progressive multifocal lenses.

[0017] Compared with existing technologies, the advantages of this invention are as follows: By setting a first magnetic component and a second magnetic component that cooperate with each other between the main frame and the magnetic lens holder, this invention enables quick magnetic installation and removal of reading lenses. Users only need to bring the magnetic lens holder close to the front of the main frame, and it will automatically align and firmly attach under magnetic guidance, completing the switch to near vision mode. The entire process requires no tools, greatly simplifying the process for people with both myopia and presbyopia to switch between near and far vision, avoiding the tedious operation of frequently removing and replacing the entire pair of glasses, and significantly improving the convenience of daily use.

[0018] This utility model of magnetic reading glasses features a foldable nose pad assembly. The left and right nose pad arms are connected by a hinge, allowing for free folding within a range of 0° to 180°. This enables the lenses to be folded in half for storage when not in use, significantly reducing the overall size. The modular structure allows users to purchase only one main frame for myopia correction, and then select different diopter (e.g., +1.00D, +1.50D, +2.00D, +2.50D, +3.00D) magnetic reading glasses lenses according to their presbyopia level for multi-scenario vision correction. Compared to expensive and difficult-to-fit progressive multifocal lenses, this utility model significantly reduces the cost of eyeglasses for users, while avoiding dizziness and instability caused by ill-fitting progressive lenses, offering higher cost-effectiveness and greater potential for widespread adoption. Users can achieve a wider and clearer reading field of view in near-vision situations, reducing eye fatigue and improving visual comfort. Meanwhile, when using the glasses at a distance, simply remove the lens to restore the original myopia correction function of the main frame, achieving a seamless switch between near and far vision. It is highly adaptable and provides a more natural and smooth user experience.

[0019] This invention targets users of different ages and presbyopia levels. The product offers a variety of magnetic lenses with positive refractive power, allowing users to flexibly change lenses according to changes in their vision without needing to customize an entire pair of glasses. This structure not only extends the lifespan of the main frame but also enhances the product's personalized service capabilities. It is suitable for a wide range of people with both myopia and presbyopia, exhibiting good market adaptability and user coverage. The reading lenses feature a concave structure, with a flat or slightly convex outer surface and a concave inner surface, making the lenses thinner and lighter, effectively reducing wearing burden. Simultaneously, this structure maintains an appropriate gap between the reading lenses and the myopia lenses in the main frame during magnetic assembly, preventing direct contact and friction between the two lenses, preventing scratches on the optical surfaces, extending lens lifespan, and improving the stability and safety of the optical system. The magnetic connection structure is precise, resulting in a tight fit after magnetic attraction without significant misalignment or looseness, and the overall appearance is close to a one-piece glasses design, without any abruptness. The lightweight frame can be made of plastic or flexible silicone to cover the lens edges and integrate a second magnetic component, further enhancing the product's texture and aesthetics.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are one specific implementation of this utility model and are not limited to all embodiments.

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1: A pair of magnetically attached near and far vision glasses includes a pair of glasses for mounting near-vision lenses 2 and a main frame 1. The outer edge of the main frame 1 is provided with a first magnetic component 3. The pair of glasses also includes a pair of foldable magnetically attached reading lenses 4. The magnetically attached reading lenses 4 includes a pair of reading lenses 5 with positive refractive power, a folding nose pad assembly 6 connecting the two lenses, and a second magnetic part 7 disposed on the outer side of the lens. The first magnetic component 3 and the second magnetic part 7 are magnetically engaged, so that the magnetically attached reading lenses 4 can be attached to the front of the main frame 1, realizing the optical superposition of the reading lenses 5 and the near-vision lenses 2 for near vision.

[0033] The reading lens 5 adopts a concave structure, that is, the outer surface of the lens is flat or slightly convex, and the inner surface is concave, which reduces the overall thickness of the lens and maintains a gap between it and the myopia lens 2 of the main frame 1 in the adsorption state to avoid physical contact.

[0034] The diopter of the reading lenses 5 ranges from +1.00D to +3.00D, specifically including at least one of the following specifications: +1.00D, +1.50D, +2.00D, +2.50D, and +3.00D. Users can replace the lenses with matching magnetic sleeves according to their degree of presbyopia.

[0035] The folding nose pad assembly 6 includes a left nose pad arm 601 and a right nose pad arm 602 connected by a hinge 603. The left nose pad arm 601 and the right nose pad arm 602 can rotate relative to each other around the hinge 603 to achieve folding from 0° to 180°, so that the magnetic lens 4 of the reading glasses can be folded in half and stored when not in use.

[0036] The left nose support arm 601 and the right nose support arm 602 are equipped with soft nose pads 604 at their ends. The soft nose pads 604 are made of silicone or TPE material to improve wearing comfort.

[0037] The first magnetic component 3 consists of multiple permanent magnets or ferromagnetic blocks embedded on the outside of the main frame 1. The second magnetic component 7 consists of dissimilar permanent magnets positioned at corresponding positions on the magnetic sleeve 4 of the reading glasses. After magnetic attraction, they achieve automatic alignment and stable fixation.

[0038] The magnetic lens sleeve 4 for reading glasses has a lightweight plastic or flexible silicone frame around the lens edge. The frame covers the lens edge and integrates a second magnetic part 7 to enhance structural strength and magnetic adhesion stability.

[0039] The main frame 1 is a full-rim, semi-rim, or rimless structure, and the material is selected from one of titanium alloy, TR90, acetate, or metal alloy, and is compatible with commercially available regular myopia frames.

[0040] The magnetic reading glasses case 4 weighs no more than 10 grams and is less than 15 millimeters thick when folded, making it easy to carry around.

[0041] Users can achieve near vision mode by attaching the magnetic lens 4 of reading glasses to the main frame 1, and restore distance vision mode by removing the lens 4, thus achieving a quick switch between near and distance vision without the need to wear two pairs of glasses or use progressive multifocal lenses.

[0042] The working principle of the near and far dual-lens magnetic glasses is that optical superposition and magnetic quick connection, through the coordinated cooperation of the main frame 1 and the detachable reading lens magnetic sleeve 4, enables nearsighted users to conveniently switch between near and far vision modes.

[0043] Distance mode: The user wears the main frame 1 equipped with myopia lenses 2 daily to correct distance vision. At this time, the reading glasses magnetic lens sleeve 4 is not used. The main frame 1 is worn independently, providing a wide field of vision and stable optical performance, suitable for walking, driving, and viewing distant objects.

[0044] Near-field mode: When users need to perform close-range visual activities, including reading, writing, using a mobile phone, or sewing, they can take out the magnetic folding reading glasses case 4 and unfold it. The case is equipped with a pair of reading lenses 5 with a positive refractive power of +1.00D to +3.00D to compensate for the decline in accommodative ability caused by presbyopia.

[0045] When the unfolded magnetic lens 4 of the reading glasses is aligned with the front of the main frame 1 and close to the frame, the second magnetic part 7 on the lens 4 and the first magnetic part 3 on the outer edge of the main frame 1 generate a magnetic force of opposite polarity attraction, achieving automatic alignment and firm adsorption. At this time, the reading lens 5 and the myopia lens 2 on the main frame 1 form a coaxial optical superposition structure.

[0046] According to the principle of optical superposition, the effective refractive power after combination is the algebraic sum of the two. For example, if the primary lens is -3.00D for myopia of 300 degrees, and it is paired with a +1.50D presbyopic lens, then the total refractive power for near use is: -3.00D + (+1.50D) = -1.50D, which meets the refractive state required for near reading, and there is no need to fit special presbyopic glasses or progressive multifocal lenses.

[0047] The reading lens 5 features a concave structure, meaning the outer surface is flat or slightly convex, while the inner surface is concave. This significantly reduces the overall thickness and weight while maintaining optical performance, preventing physical collisions or friction between the lens and the main lens after assembly, thus improving wearing safety and comfort. Simultaneously, the lightweight structure combined with a magnetic fixation method ensures overall structural stability and prevents wobbling when stacked.

[0048] Quick switching and storage: After use, users can simply flick the lens to remove it from the main frame 1, and then fold the lens in half using the folding nose pad assembly 6. The folding angle can reach 180°, greatly reducing the size and making it easy to put into a pocket, wallet or glasses case for easy carrying.

[0049] Multi-scenario adaptation: Users can choose different prescription reading glasses magnetic lenses 4, such as +1.00D and +2.00D, according to different near-use needs, including reading, fine crafts, and computer office work, to achieve personalized visual adjustment, one lens for multiple uses, and switch as needed.

[0050] The working process of the near- and far-vision dual-lens magnetic glasses is as follows: through the cooperation of the main frame 1 and the foldable reading lens magnetic sleeve 4, the user can quickly and conveniently switch between near and far vision needs. The entire operation does not require changing the entire pair of glasses, nor does it rely on progressive multifocal lenses. The specific workflow is divided into the following steps:

[0051] Step 1: Daily Wear of Main Frame 1, Distance Use Mode: The user wears the main frame 1 with pre-installed myopia lenses 2 to correct distance vision. The main frame 1 has a conventional structure, is comfortable to wear, and is suitable for everyday activities such as walking, driving, and watching television at a distance. At this time, the magnetic lens sleeve 4 for reading glasses is in an unused state and can be folded and stored in a pocket, wallet, or glasses case for easy carrying without adding extra burden.

[0052] Step Two: Take out the lens when close-up work is needed: When the user needs to engage in close-up activities such as reading, looking at a mobile phone, sewing, or writing, take out the magnetic lens 4 from the portable storage compartment. Because the lens has a foldable structure, the unfolding process is simple and quick. Just unfold the two nose pad arms along the hinge axis 603 to about 180° to restore it to its complete usage form.

[0053] Step 3: Magnetic installation of the reading lens sleeve, switching to near vision mode: Align the unfolded magnetic reading lens sleeve 4 with the front of the main frame 1, close to the frame. The second magnetic part 7 on the outer side of the sleeve and the first magnetic part 3 on the outer edge of the main frame 1 generate opposite magnetic attraction, automatically aligning and firmly adhering. The entire installation process does not require precise alignment by hand or the use of tools; it can be completed with one hand in 1-2 seconds. After adsorption, the reading lens 5 and the myopia lens 2 on the main frame 1 achieve coaxial optical superposition, forming a composite optical system of myopia and reading glasses. According to the principle of refractive power superposition, the near vision refractive power is the sum of the two, meeting the requirement for clear near vision. For example: Main lens: -3.00D; myopia 300 degrees; reading lens sleeve: +1.50D, presbyopia 150 degrees.

[0054] Actual near-vision refractive power: -3.00D + (+1.50D) = -1.50D, suitable for reading distance of 30~40cm.

[0055] Step 4: Maintain stable wear during use: The magnetic structure provides sufficient clamping force to ensure that the lens sleeve will not fall off due to head shaking or slight bumps during normal use. Meanwhile, the reading lens 5 features a concave structure, making it thinner and lighter overall, and maintaining a safe gap with the main lens to avoid mutual friction or optical interference. The folding nose pad assembly 6 unfolds to fit snugly against the bridge of the nose, providing stable support and improving wearing comfort and stability.

[0056] Step 5: Remove and fold for storage after use: After completing near-vision activities, the user gently pinches both sides of the lens with their fingers to overcome the magnetic attraction and remove it from the main frame 1. Then, fold the nose pad assembly along hinge 603, achieving a folding angle of 90°~180°, reducing the lens size to less than half its original size for easy storage in small spaces. The main frame 1 is then restored to its independent wearing state and can continue to be used for distance vision, achieving a seamless transition between functions.

[0057] Step Six: Replace lenses with different prescriptions as needed. For different near-vision scenarios, such as +2.00D for detailed reading and +1.00D for computer work, users can equip multiple magnetic lens sets with different prescriptions. By changing the corresponding lens sets, personalized and scenario-based visual adjustments can be achieved, realizing one main frame for multiple uses.

[0058] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
