[0026] The following will be combined with the 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.

[0027] refer to Figures 1 to 4 , a contact lens wearing aid, comprising:

[0028] A suction cup 1 adapted for contact lenses;

[0029] The handle 2 is connected to the suction cup 1. The handle 2 is provided with a plurality of mutually connected pressing air cavities 21. The suction cup 1 is provided with an air hole 11. The pressing air cavities 21 are connected to the air hole 11. The plurality of pressing air cavities 21 are arranged in a direction away from the suction cup 1. The width of each pressing air cavity 21 is greater than the width of the connection between two adjacent pressing air cavities 21. The handle 2 is made of a soft material at the corresponding pressing air cavity 21.

[0030] The air pressure driving force generated by one pressing air cavity 21 when pressed is smaller than the air pressure driving force generated by the other pressing air cavity 21 when pressed.

[0031] Through the arrangement of the above structure, the suction cup 1 is adapted to the shape of the contact lens so as to adsorb the lens. The suction cup 1 is connected to the handle 2 so that the user can operate the wearing auxiliary tool of this embodiment. The handle 2 is provided with a plurality of mutually connected and arranged pressing air cavities 21, and the width of each pressing air cavity 21 is greater than the width of the connection with the adjacent pressing air cavity 21. Such a design enables different air pressure driving forces to be generated when pressing different air cavities 21, so that the user can easily adsorb the contact lens on the suction cup 1 or detach the contact lens from the suction cup 1, wherein the force of the suction cup 1 adsorbing the contact lens is less than the driving force of the suction cup 1 detaching the contact lens.

[0032] Specifically, when pressing the pressing air cavity 21 close to the suction cup 1, the air pressure driving force generated is greater than the air pressure driving force generated when pressing the pressing air cavity 21 away from the suction cup 1. Because when pressing the pressing air cavity 21 close to the suction cup 1, the deformation of the internal cavity of the handle 2 is greater than when pressing the pressing air cavity 21 away from the suction cup 1.

[0033] Thus, when the user needs to put on a contact lens, they first press the pressing cavity 21 away from the suction cup 1. The air pressure inside the cavity 21 decreases, creating a negative pressure that causes the suction cup 1 to generate an adsorption force, adsorbing the contact lens to its surface. When the user then places the contact lens on their eye, they finally press the pressing cavity 21 closer to the suction cup 1 to release the lens from the suction cup 1, completing the process of putting on the contact lens. When the user needs to remove the contact lens, they can press any of the pressing cavities 21, using the generated negative pressure to adsorb the lens and remove it from the eyeglasses.

[0034] The suction cup 1 and the pressing air cavity 21 are both made of soft materials, and the specific materials may be rubber, silicone, soft resin, etc., so that the user can press the pressing air cavity 21.

[0035] The wearing aid of this embodiment is suitable for hard contact lenses, such as orthokeratology lenses (OK lenses), rigid gas permeable contact lenses (RGP lenses), etc.

[0036] In one embodiment, the width of the outer wall of the handle 2 at the location corresponding to the connection between two adjacent pressing cavities 21 is a first width 22, and the width of the outer wall of the handle 2 at the location corresponding to the pressing cavities 21 is a second width 23, where the first width 22 is smaller than the second width 23. This design makes it easier for the user to distinguish the location of each cavity, so that the user can determine which cavity 21 to press when sucking or releasing a contact lens.

[0037] In one embodiment, the handle 2 is further provided with a cavity 24 connected to the air hole 11 at one end close to the suction cup 1. The air hole 11 is connected to the pressing air cavity 21 through the cavity 24. The width of the cavity 24 gradually decreases in the direction away from the pressing air cavity 21 to facilitate user operation.

[0038] This structural design ensures smoother and more even air pressure transfer from the pressure chamber 21 through the cavity 24 into the air hole 11. The gradually decreasing cavity 24 allows for better concentration of air pressure, preventing pressure loss and thus increasing the overall force of the air pressure. This design not only helps improve the suction cup's ability to hold the contact lens, but also ensures that the user can more easily control the airflow when releasing the suction cup, allowing for smooth lens removal.

[0039] At the same time, the tapered design of the cavity 24 also makes the structure more compact, preventing the short distance between the pressing cavity 21 and the suction cup, which would result in insufficient air pressure driving force generated by pressing the cavity 21, thereby improving the operational stability and convenience of the handle 2. During operation, the user can easily control the air pressure by pressing the cavity 21 to achieve the suction and release functions of the contact lens.

[0040] In one embodiment, the distance between the suction cup 1 and the pressing cavity 21 is 5 mm to 10 mm. This distance ensures that air pressure is effectively transferred between the suction cup 1 and the pressing cavity 21 during operation, ensuring that the suction cup 1 can firmly hold the contact lens while allowing the air pressure from the pressing cavity 21 to be quickly released, making it easy for the user to remove the lens when needed.

[0041] The precisely calculated distance range of 5mm to 10mm ensures neither too close (causing insufficient air pressure) nor too far (causing poor air pressure transmission), thereby improving operational efficiency and accuracy. Furthermore, this design enhances the overall controllability of the handle 2, allowing users to more comfortably control the suction and release processes, further optimizing the contact lens wearing experience.

[0042] In one embodiment, the ratio of the diameter of the air hole 11 to the width of the pressing air cavity 21 is 1 / 12-1 / 6. Specifically, the design of the air hole 11 can effectively control the flow rate and pressure distribution of the airflow by adjusting its diameter. When the diameter of the air hole 11 is small, the flow rate of the airflow through the air hole 11 is high, and the pressure generated is small; when the diameter of the air hole 11 is large, the flow rate of the airflow through the air hole 11 is low, and the pressure generated is high. By reasonably setting the ratio of the diameter of the air hole 11 to the width of the pressing air cavity 21, precise control of the airflow can be achieved, thereby improving the efficiency and stability of the user when wearing contact lenses. For example, when the width of the air cavity 21 is 12 mm, the diameter of the air hole 11 can be set to between 0.7 mm and 2 mm to ensure that the airflow in the air cavity 21 flows smoothly, thereby improving the wearing stability.

[0043] In one embodiment, the height of the pressing air cavity 21 is between 4 mm and 8 mm. Such a design can ensure smooth airflow in the air cavity 21 while providing sufficient space to achieve appropriate pressure distribution and adjustment functions. When the height of the pressing air cavity 21 is small, the air flow speed inside the air cavity 21 is relatively fast, which is suitable for application scenarios that require a higher flow rate; when the height increases, the air flow speed inside the air cavity 21 slows down and the pressure is more stable. This height range setting can be adjusted according to the different needs of users to ensure a reasonable distribution of airflow pressure, thereby improving wearing comfort and use effect. For example, in some cases, selecting an air cavity 21 design with a height of 6 mm can achieve smooth flow and precise control of airflow, thereby improving wearing stability.

[0044] In one embodiment, the thickness of the suction cup 1 gradually decreases in the direction away from the air hole 11. Such a design can effectively enhance the sealing between the suction cup 1 and the contact surface of the contact lens and improve the adsorption effect. The change in the thickness of the suction cup 1 can make the edge softer while maintaining the stability of the central part, thereby increasing the fit with the contact surface of the contact lens. This structure helps to reduce gas leakage, ensures more precise airflow control at the air hole 11, and maintains a stable adsorption effect during wearing or use. For example, the center thickness of the suction cup 1 is larger, which can provide stable support, while the edge gradually becomes thinner, so that it can fit more closely to the surface of the contact lens, further improving the wearing effect and comfort of the contact lens.

[0045] In one embodiment, the diameter of the pressing air cavity 21 is larger than the diameter of the handle 2. This design can provide a larger contact area during use, enhancing stability and controllability during pressing. The larger diameter of the air cavity 21 allows for better pressure dispersion during pressing, avoiding excessive local pressure, thereby improving the comfort and operating accuracy of the device. At the same time, the smaller diameter of the handle 2 helps the user to hold and control the device more easily during use, improving the convenience and flexibility of operation. For example, when the diameter of the pressing air cavity 21 is 20 mm, the diameter of the handle 2 can be designed to be 15 mm, thereby ensuring that the pressing air cavity 21 can provide sufficient stability during operation, while the handle 2 can maintain a good grip.

[0046] In one embodiment, the suction cup 1 and the handle 2 are integrally formed, and the handle 2 is solid.

[0047] Through the above structure, the suction cup 1 and the handle 2 are integrally formed to save production technology, reduce production costs, improve production efficiency, and make the product more beautiful. Of course, in other embodiments, the suction cup 1 can be an independent component. In addition, the handle 2 is a solid design, which not only improves its strength and stability when gripping, but also makes the handle 2 have better resistance to deformation when under pressure, thereby ensuring a stable operating experience during use. For example, during use, the solid handle 2 can effectively resist external forces from different directions, while the integrally formed suction cup 1 ensures a close fit with the surface of the contact lens, further improving the overall performance of the contact lens wearing aid.

[0048] In one embodiment, the suction cup 1 has a concave surface 12 and a convex surface 13. The concave surface 12 is a curved surface, and the shape of the concave surface 12 is adapted to the outer surface of the contact lens. The convex surface 13 is connected to the handle 2; the top of the handle 2 is connected to a decorative piece 25 for decoration.

[0049] Through the above-described configuration, the shape of the suction cup 1 is specifically designed to adapt to the outer surface of the contact lens, ensuring a tight fit during use and providing stable suction. This adaptive design effectively prevents gas leakage and improves wearer stability and comfort. Furthermore, the convex surface 13 of the suction cup 1 is connected to the handle 2 to form an integrated structure, ensuring stability during operation.

[0050] Furthermore, a decorative piece 25 is attached to the top of the handle 2. This decorative piece 25 not only provides aesthetically pleasing decoration but also offers users a personalized look. The decorative piece 25 can be designed in a variety of shapes and colors to suit user preferences, enhancing the product's appeal and providing a more comfortable grip during operation. For example, the decorative piece 25 could be designed in the shape of a cat, frog, or other figure, adding to the product's visual appeal while also helping users better identify and use the tool.
