[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A one-handed contact lens wearing aid, such as Figures 1 to 5 As shown, it includes two grip handles 1, each with a plastic eye support 12 fixedly mounted at one end. The two grip handles 1 are rotatably connected. A support rod 9 is rotatably mounted on the top of the upper grip handle 1. A sealing sleeve 3 is fixedly mounted on the top of the support rod 9. A contact lens suction cup 4 is fixedly mounted on one end of the sealing sleeve 3. A thin film 13 is fixedly mounted on the inner wall of the contact lens suction cup 4. A connecting rod 2 is rotatably mounted on the grip handle 1 via a pin 8. A connecting ring 10 is fixedly mounted on one end of the connecting rod 2. A movable rod 7 is rotatably mounted at the contact point of the inner walls of the two connecting rings 10. The movable rod 7 is inserted into the sealing sleeve 3, and a piston 14 adapted to the sealing sleeve 3 is fixedly mounted on one end of the movable rod 7.

[0022] like Figure 2 As shown, each of the two grip handles 1 is provided with a connecting plate 6. The upper and lower connecting plates 6 are rotatably connected by a pin. The pin rotatable connection is common knowledge in the field and is not shown in the figure. The bottom of the support rod 9 is integrally formed with a rotating shaft, which is rotatably connected to the connecting plate 6 located above.

[0023] like Figure 1 and Figure 2As shown, a soft silicone eye support 5 is connected to one side of the plastic eye support 12 via a support shaft. The soft silicone eye support 5 is made of medical-grade silicone material, which reduces discomfort during wear. An anti-slip silicone inner ring 11 is fixedly provided on the inner wall of the grip handle 1. Multiple anti-slip protrusions 15 are fixedly provided on the inner wall of the anti-slip silicone inner ring 11. The anti-slip silicone inner ring 11 and the anti-slip protrusions 15 increase the friction between the user's hand and the grip handle 1, preventing slippage.

[0024] like Figures 1 to 5 As shown, the grip handle 1, plastic eye support 12, connecting plate 6, support rod 9, movable rod 7, connecting rod 2, sealing sleeve 3, and connecting ring 10 are all made of transparent ABS material.

[0025] When using the device, the user aligns the contact lens with the contact lens suction cup 4 and closes the handle 1 with one hand. The four-bar linkage of the connecting rod 2 converts the rotational motion of the handle 1 into the reciprocating motion of the movable rod 7. This, in turn, drives the piston 14 to move within the sealing sleeve 3. The piston 14, the diaphragm 13, and the sealing sleeve 3 form a sealed air chamber. When the handle 1 is closed, the movable rod 7 moves the piston 14 backward, causing a decrease in air pressure. This causes the diaphragm 13 to indent inward, creating a negative pressure environment that firmly adheres the contact lens to the underside of the diaphragm 13. The user then brings the tool close to the eye, and as the soft silicone eye support 5 contacts the eyelid, slowly opens the handle 1, gently stretching the eyelid. The eyelids create suitable conditions for wearing contact lenses. At the same time, by controlling the opening of the handle 1, the piston 14 moves forward in the sealed air chamber, causing the air pressure to rise. This causes the membrane 13 to bulge outward, creating a high-pressure environment. The pressure difference is used to push the contact lens off the membrane 13, allowing the contact lens to fit the eyeball, thus completing the wearing of the contact lens. It can be operated with one hand, greatly simplifying the wearing process. It is suitable for all types of people. Furthermore, through reasonable design and appropriate material selection, discomfort during the wearing process is reduced. Through intuitive opening and closing control, users can master the use method without complicated learning. The reasonable structural design avoids the risk of contact lens falling out or damaging the eyes.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
