Description

Technical Field

[0001] This invention relates to the field of contact lens cleaning and care, and more particularly to a contact lens care device and its care method. Background Technology

[0002] Currently, some contact lens care devices have non-removable care components, making it difficult to clean the care chamber properly and leading to contamination of the contact lenses with prolonged use. Other care components can be removed, but they are prone to leakage, which can cause short circuits, oxidation and rust of conductive parts, poor contact, and other issues, affecting the lifespan of the care device.

[0003] The two compartments within the nursing unit are designed and manufactured with the possibility of leaks, which can cause solution leakage or mixing, affecting the nursing effect or the normal use of the nursing device.

[0004] Commercially available skincare solutions are generally alkaline, requiring specialized preparation and thus imposing a cost burden on users. Furthermore, alkaline solutions present numerous inconveniences during storage and use. Therefore, finding a safe, harmless, inexpensive, and affordable skincare solution that also achieves excellent cleaning and sterilization effects has become a pressing issue for researchers in the industry.

[0005] In addition, current contact lens solutions or some conventional sterilization and protein removal devices do not have special protective measures, which can easily cause the contact lenses to fade or partially fade, making it impossible to distinguish between the left and right eyes or affecting the aesthetics of wearing them, thus affecting the normal use of the contact lenses.

[0006] To address the above problems, a new technical solution is necessary. Summary of the Invention

[0007] To address at least one of the technical problems existing in current technologies, this invention proposes a novel contact lens care device and method. The device features an ingenious structural design that avoids the common problem of solution leakage into the care tank due to user laziness. Furthermore, the novel care component design of this patent avoids the issue of leaks and simplifies assembly. The specific solution is as follows:

[0017] The inner compartment includes an inner compartment side wall and an inner compartment bottom wall. The inner compartment has an outer edge extending outward from the side wall of the inner compartment along the direction of the inner compartment bottom wall. The compartment includes a compartment wall and an inner compartment opening at the bottom of the compartment. A second annular ultrasonic line is provided on one side of the bottom of the compartment wall. The inner compartment is received in the compartment from the inner compartment opening. The outer edge is stopped at the bottom of the compartment wall. The bottom of the compartment wall is sealed to the outer edge through the second annular ultrasonic line.

[0018] As a preferred embodiment of the contact lens care device described in this patent, the care component further includes a pressure plate with a second through hole corresponding to the through hole, and the pressure plate presses the cation exchange membrane against the inner side wall of the chamber.

[0019] As a preferred embodiment of the contact lens care device described in this patent, a third annular ultrasonic line is provided on the pressure plate, and the pressure plate is sealed to the inner side wall of the compartment through the third annular ultrasonic line, with the third annular ultrasonic line on the same plane.

[0022] As a preferred embodiment of the contact lens care device described in this patent, the control system further includes a remote transmission port, and the care device is configured to transmit data with the cloud and client via the remote transmission port.

[0023] As a preferred embodiment of the contact lens care device described in this patent, it also includes a storage component, which includes a storage component body, a storage compartment on the storage component body, and a storage sealing cover on the storage compartment.

[0024] The top and side components also form a storage compartment, in which the storage components are housed.

[0025] As a preferred embodiment of the contact lens care device described in this patent, the top component is further provided with an accessory storage slot, and the accessory storage slot is provided with a disinfection and sterilization structure, which can disinfect and sterilize the accessories in the accessory storage slot.

[0026] On the one hand, the present invention provides a method for caring for contact lenses, specifically including the following steps:

[0027] S1: Pour chloride ion-containing solution into the nursing chamber and the auxiliary chamber. A cation exchange membrane is set between the nursing chamber and the auxiliary chamber. At least a first electrode and a second electrode are set in the nursing chamber, and a third electrode is set in the auxiliary chamber. The contact lens is placed in the chloride ion-containing solution in the nursing chamber.

[0028] S2: Connect the first and third electrodes to the power supply. The first electrode is the cathode, and the third electrode is the anode. An oxidation reaction occurs at the third electrode, which removes Cl- from the chloride ion solution in the auxiliary chamber. - Electrolysis produces Cl2, which dissolves in the solution to generate HCl and HClO. A reduction reaction occurs at the first electrode, which electrolyzes H2O in the chloride-containing solution within the nursing chamber to produce H2 and OH-. - The cation exchange membrane provides an alkaline environment within the care chamber.

[0029] S3: After step S2 has reacted for a period of time, disconnect the power supply to the first and third electrodes, and connect the power supply to the first and second electrodes. One of the first and second electrodes is the anode, and the other is the cathode. The cathode electrolyzes the H2O in the solution to produce H2 and OH-. - The anode will react with Cl in the solution. - Electrolysis produces Cl2, which dissolves in the solution to produce Cl.- and ClO - The ClO - It can sterilize and degrade proteins on contact lenses. Under the action of the electric field force formed between the anode and cathode, the proteins on the contact lens move towards the electrode with the opposite charge, thereby achieving sterilization and protein removal of the contact lens.

[0030] As a preferred embodiment of the contact lens care method described in this patent, in step S2, the power-on voltage for connecting the first and third electrodes is not less than 1.1V, the stable voltage after connecting the first and third electrodes is 3.5-7.5V, and the power is disconnected after the first and third electrodes react for 2-11 minutes; and / or

[0031] In step S3, the power-on voltage of the first electrode and the second electrode is not less than 1.1V, the stable voltage of the first electrode and the second electrode after power-on is 3.5-6.5V, and the reaction time of the first electrode and the third electrode after power-on is 10-30 minutes.

[0032] Compared with the prior art, the technical solution described in this patent has at least one or more of the following beneficial effects:

[0033] The nursing component is designed for side-mounted placement. When a user pours a solution into the nursing component, the user is forced to remove the nursing component from the nursing device. This prevents the user from pouring the solution directly into the nursing component from the nursing device, which could cause the solution to leak into the nursing device, leading to rust, short circuits, poor contact, etc. at the contact points on the nursing device, affecting the service life of the nursing device or even damaging it.

[0034] A set distance is set between the electrical contact point and the bottom of the side wall of the care tank to prevent solution or water stains from spilling into the care tank, thereby avoiding abnormalities such as rusting, short circuits, and poor contact at the electrical contact point.

[0035] The conductive contacts are located on the side, not the bottom, making them waterproof and oxidation-resistant. This side placement also prevents the care unit from tilting when removed, thus preventing spillage or mixing of solutions inside. Furthermore, the conductive contacts are spring-loaded probes with an interference fit to ensure good electrical contact with the care device. Additionally, the conductive contacts are positioned within a second limiting groove to protect them from splashes of water or contact with wet hands when handling the care unit.

[0036] The sealing lines on the nursing component or the inner chamber are on the same plane, ensuring a leak-proof seal and preventing leakage or capillary siphoning that could cause the solutions in the nursing and auxiliary chambers to mix. Furthermore, this design brings the sealing lines closer to the ultrasound source.

[0037] The device is equipped with an interactive module and a remote transmission port, through which it can exchange data with the cloud, client, and other devices.

[0038] The data transmitted between the two systems includes user age, glasses prescription, and the time, frequency, or cycle for regular reminders to care for contact lenses, as well as the recorded care time and frequency of care devices. This makes the system more user-friendly and convenient.

[0039] This patent uses a neutral NaCl solution as the initial care solution, which is inexpensive and readily available, reducing care costs for consumers. The neutral NaCl solution contains no added acids or alkalis, is non-corrosive, and poses no chemical hazards, ensuring high safety and significantly reducing production, storage, and transportation costs. It is suitable for contact lenses, including but not limited to orthokeratology (Ortho-k) lenses, scleral lenses, and regular contact lenses, especially Ortho-k lenses. Ortho-k lenses are rigid gas-permeable contact lenses with corneal reshaping function, typically made of highly oxygen-permeable rigid corneal contact lens materials.

[0040] This patented technology automatically adjusts the pH value of a solution using a unique structure and method, offering high flexibility. By incorporating an auxiliary chamber, where the third electrode serves as the anode, and connecting it to the cathode within the nursing chamber, the anode enables the anode to produce ClO₂ within the auxiliary chamber. - The cathode causes OH to be generated inside the nursing chamber. - The solution inside the care chamber is alkaline, so an auxiliary chamber is set up to adjust the pH value within the care chamber, ensuring that only a neutral NaCl solution is needed as the original care solution. This makes the original care solution not only versatile and readily available, but also safe and harmless as it does not contain acidic or alkaline substances, greatly facilitating user operation, production, storage, and transportation. Furthermore, the alkaline environment of the care chamber inhibits the formation of HClO, preventing HClO from fading the lenses. Hypochlorite ions mostly exist in the form of NaClO, which has a relatively mild bactericidal and protein-removing effect and poor bleaching performance under alkaline conditions, thus preventing lens fading. The ClO in NaClO... - Ions can kill bacteria and degrade proteins, and with the help of electrophoresis, they can remove proteins.

[0041] Meanwhile, the presence of the cation exchange membrane ensures a highly alkaline environment within the care chamber, inhibiting the generation of HClO and its impact on lens fading.

[0042] First, one of the first and second electrodes in the nursing chamber is used as the cathode, and the third electrode in the auxiliary chamber is used as the anode. When the power is turned on, a reduction reaction occurs at the cathode in the nursing chamber, where the cathode electrolyzes H2O in the chloride ion-containing solution to produce H2 and OH-. - At this point, the pH of the solution in the nursing chamber is greater than 7, indicating alkalinity. An oxidation reaction occurs at the anode, where Cl- ions from the chloride-containing solution are removed.- Electrolysis produces Cl2, which dissolves in the solution to generate HCl and HClO. Due to the action of the cation exchange membrane, NaOH at the first electrode cannot enter the auxiliary chamber, thus ensuring the pH value within the care chamber remains stable. After a period of reaction, the OH- in the care chamber... - As the pH of the solution in the nursing chamber increases, the power is disconnected once it reaches the desired value. Then, the power to the first and second electrodes in the nursing chamber is turned on. One electrode of the first and second electrodes is the cathode, and the other is the anode. The cathode continues to generate OH-. - The anode will react with Cl in the solution within the nursing chamber. - Electrolysis produces Cl2, which dissolves in a strongly alkaline solution within the nursing chamber to produce NaClO and NaCl. - It can sterilize and degrade proteins on contact lenses. The proteins on the surface of the contact lens also move towards the electrode opposite to their own charge under the action of the electric field force formed between the anode and cathode, ultimately achieving the effect of sterilizing and removing proteins from the contact lens.

[0043] The electrochemical cleaning and sterilization technology of this patent has excellent sterilization and protein removal effects, effectively degrades proteins, sterilizes instantly, and does not damage the contact lens itself during the sterilization and protein removal process. It has good stability and low toxicity and side effects.

[0044] The anode in both the nursing chamber and auxiliary chamber is at least a chlorine-evolving electrode. In the sodium chloride solution, the anode undergoes an oxidation reaction, releasing chlorine gas from chloride ions in the solution. Chlorine-evolving electrodes possess strong corrosion resistance, high chlorine and acid resistance, good stability, good oxidation resistance, and a long service life. They prevent the anode itself from reacting or producing other products that could contaminate the electrolyte or cathode products. They also facilitate the removal of air bubbles between electrodes and on the electrode surface, effectively reducing the voltage in the electrolytic cell. Their shape is easy to manufacture, allowing for high precision. Generally, ruthenium-based, iridium-based, and platinum-based metal electrodes are preferred. Other inert electrodes (such as graphite and graphene materials) can also be used as chlorine-evolving electrodes provided the material's morphological stability is ensured. Electrodes can also be coated electrodes. The preferred electrode substrate is titanium or a titanium alloy substrate, coated with ruthenium-based, iridium-based, or platinum-based metal coatings. The cathode and anode are preferably symmetrically distributed on both sides of the nursing chamber, close to the sidewalls for better protein removal.

[0045] Commercially available contact lens solutions can easily damage contact lenses, and their sterilization rate is only around 90%. This patented solution achieves instant sterilization, not only with excellent sterilization effect but also with rapid sterilization speed. It achieves a 99% bacterial kill rate and a 99% fungal kill rate within 3 minutes, and kills Bacillus subtilis within 10 minutes, reaching the sterilization level.

[0046] When the first and second electrodes in the nursing chamber of this patent are energized, the chloride ion solution generates several types of oxidizing substances and free radicals, especially hypochlorous acid and hypochlorite ions, which can damage the peptide chains of proteins. The preferred mass concentration of hypochlorite ions in this patent is 0.1%, and the hypochlorite ion concentration of solution A in the AB solution is 0.375%. Although the AB solution can achieve good sterilization and protein removal effects, the contact lens cannot be immersed in the AB solution for a long time; otherwise, the AB solution will damage the contact lens, such as causing fading and corrosion. This patent, due to the addition of electrophoresis technology, achieves excellent sterilization and protein removal effects with a preferred hypochlorite ion concentration of 0.1%, less than one-third of that in the AB solution. This makes it safer and easier to use, and by appropriately controlling relevant parameters, it can reduce fading of the contact lens and prevent coating damage and corrosion.

[0047] The mass concentration of hypochlorite ions in this invention is controlled within the range of 0.01%-0.4%.

[0048] Through extensive and long-term research, researchers discovered the optimal concentration range of hypochlorite ions and figured out how to maintain this concentration within the optimal range under certain experimental conditions. These conditions include an optimal sodium chloride solution concentration of 0.9%, a power-on voltage of no less than 1.1V for both the first and second electrodes, a stable operating voltage range of 3.5-6.5V after power-on, and a reaction time of 10-30 minutes after power-on.

[0049] The chloride ion-containing solution of this patent can generate hydroxyl radicals (OH·), oxygen radicals (O·), chloride radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), and hypochlorite ions (ClO2) under the action of an electric field. - Hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H+) + The combination of substances such as [list of substances], along with electrophoresis under specific conditions, results in excellent protein removal and sterilization effects, comparable to AB solution. Furthermore, compared to AB solution, the concentration of hypochlorite ions produced in the reaction is less than one-third that of AB solution, making it safer and easier to use.

[0050] The electrochemical cleaning and sterilization technology employed in this patent, compared to the traditional hand-rubbing method used in the market, applies an electrophoretic dissociation electric field that acts only on charged particles on the contact lens, such as proteins, bacteria, and fungi. This more effectively separates denatured proteins from the contact lens without damaging it. Consequently, it avoids problems such as insufficient rubbing force leading to incomplete removal of deposited proteins, excessive rubbing causing breakage, uneven rubbing causing deformation or scratches, and insufficient finger cleaning causing scratches or bacterial infections.

[0051] The electrochemical sterilization and protein removal technology of this invention can kill bacteria and other microorganisms. Its sterilization principle mainly includes the following aspects:

[0052] 1. Electrolysis produces hypochlorous acid, which blocks the protein synthesis pathway in bacteria.

[0053] Electrolysis of a chloride-containing solution produces hypochlorous acid, a highly potent oxidizing agent. Hypochlorous acid works by oxidizing and denaturing the proteins in microorganisms, preventing them from replicating and thus rendering them unable to survive. Hypochlorous acid is 80 times more effective at killing microorganisms than hypochlorite ions and generates hydroxyl radicals that target various bacteria. Furthermore, with long-term use, bacteria do not develop resistance to electrolyzed saline solution, and it has no toxic side effects on the cornea.

[0054] 2. Electroincorporation: Electroincorporation refers to the process of introducing substances from solution into cells under the influence of an electric field. Based on the effects of an external electric field on bacterial growth, activity, metabolism, morphology, and motility, it involves the generation of hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H₂O₂), ozone (O₃), and hypochlorite ions (ClO₂) after the electrolysis of a chloride-containing solution. - Hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H+) + A novel bactericidal and protein-removing technology has been developed. By applying an appropriate current, on the one hand, it can interfere with gene expression in cells, inhibit ATPase activity, reduce protein content within bacterial cells, affect free radical reactions and the synthesis of biological macromolecules, and inhibit cell proliferation by neutralizing the negative charge on the cell surface, ultimately leading to apoptosis, senescence, and death. On the other hand, it can enhance the permeability of microbial cells, causing electromixing, thereby inhibiting the generation of hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), and hypochlorite (ClO2). - Hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H+) + These substances penetrate into microbial cells, producing cytotoxicity and inducing cell structure and function disorders, thereby achieving the effects of inactivation, sterilization, and disinfection.

[0055] 3. Micro-electrolysis generates active substances that disrupt the chain structure of cellular organic matter.

[0056] Under the influence of a physical field, the current density is controlled by the energized state. Excited electrons are transferred from the anode to the cathode through the water medium. During this transfer, oxidizing substances such as O radicals and ClO are generated. - Cl - OH -H2O2 and other active substances can react with any molecules in living cells, such as sugars, phospholipids, and organic acids. The reaction is rapid, damaging the cell membrane and penetrating into the cell membrane to destroy the chain structure of organic matter. It also oxidizes the RNA and DNA of bacterial cells, causing them to become inactive or die. At the same time, bacteria are generally negatively charged in water and will migrate and aggregate towards the anode, which can cause bacterial discharge that directly kills them.

[0057] 4. Microcurrents pierce bacterial cell walls, rapidly oxidizing bacterial RNA / DNA.

[0058] The electric current acts directly on the cell wall, which can directly cause mechanical damage to bacteria in the solution and enhance the oxidation of bacterial and viral RNA and DNA.

[0059] 5. Microcurrents break up bacterial clusters and reduce bacterial tolerance.

[0060] The application of electric current alters the dispersion environment of bacteria in water, significantly reducing the stable state of bacterial aggregation. When bacteria and viruses are considered as colloidal systems composed of water, proteins, and nucleic acids, the microcurrent reduces bacterial stability, thereby decreasing their tolerance to hypochlorous acid.

[0061] 6. Electron-activated water enhances the contact surface between hypochlorous acid and bacteria.

[0062] The properties of water depend on changes in the electronic structure of water molecules, mainly changes in the distribution, shape, and direction of the electron cloud. Studies have confirmed that the electron cloud can be altered by the external environment. Under low voltage and microcurrent, four pairs of electrons in a water molecule jump from low orbits to high orbits, increasing the electron energy level and causing a loss of potential energy in activated water molecules, thus lowering their potential. This reduces the potential difference between water molecules and the interface (microbial surface). This change may affect the aggregation state of bacterial / viral particles. Furthermore, streptococci, Pseudomonas aeruginosa, and Staphylococcus aureus commonly found on contact lenses are all hydrophilic bacteria. After being exposed to microcurrent, hypochlorous acid can more easily contact these bacteria, thus improving the sterilization efficiency.

[0063] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0084] Please see Figures 1-15 ,like Figure 1-15 As shown, the present invention provides a contact lens care device, including a care component 1 and a base 2;

[0085] Nursing component 1 includes a nursing chamber body 11 and at least one inner chamber 12. The nursing chamber body 11 has at least one compartment 111. The inner chamber 12 is housed in the compartment 111. The side wall of the inner chamber 12 has a through hole 121. A cation exchange membrane 13 is sealed on the through hole 121.

[0086] The inner compartment 12 or the compartment surrounding the bottom of the compartment trough is the nursing compartment 14, and the compartment formed by the compartment trough and the inner compartment is the auxiliary compartment 15; the nursing compartment 14 is provided with at least one first electrode 141 and at least one second electrode 142. When energized, the first electrode 141 is the anode and the second electrode 142 is the cathode; the auxiliary compartment 15 is provided with at least one third electrode 151. When energized, the third electrode 151 is the anode.

[0087] The base 2 includes a top component 21 and at least one side component 22, the top component 21 and the side component 22 forming a care groove 23, in which the care component 1 is placed.

[0088] The nursing component is designed for side-mounted placement. When the user pours solution into the nursing component, the user is forced to remove the nursing component from the nursing tank. This prevents the user from directly pouring solution into the nursing component from inside the nursing tank, which could cause the solution to spill into the nursing tank, resulting in rust, short circuits, poor contact, etc. at the contact points inside the nursing tank, affecting the service life of the nursing device or even damaging the nursing device.

[0089] In the example, the solutions in the nursing chamber and the auxiliary chamber are electrically interconnected only through a cation exchange membrane.

[0090] In the example, when the nursing component 1 is placed in the nursing slot 23, the top component 21 is positioned close to the top of the nursing component.

[0091] Preferably, the nursing component 1 is magnetically attached to the nursing tank 23.

[0092] Preferably, the first electrode 141 and the second electrode 142 are symmetrically arranged inside the nursing chamber 14, with both electrodes close to the side wall of the nursing chamber 14 to achieve a better protein removal effect. In this example, the first electrode 141, the second electrode 142, and the third electrode 151 are all chlorine-electrode electrodes.

[0093] Preferably, the base 2 further includes a bottom component 25, one end of a side component 22 is connected to the top component 21, and the other end of the side component 22 is connected to the bottom component 25, the top component 21, the side component 22, and the bottom component 25 forming a care groove 23.

[0108] Preferably, the compartment 111 is further sealed with a nursing sealing cover 17, which is configured to prevent leakage of solutions in the nursing compartment and auxiliary compartment. More preferably, the nursing sealing cover 17 is provided with a vertical lens clip 171, which keeps the contact lens suspended within the nursing compartment. The vertical lens clip is a flexible lens clip. The flexible lens clip facilitates the handling of the contact lens without damaging or injuring it.

[0109] In a preferred embodiment, such as Figure 3-12As shown, the nursing assembly also includes a bottom shell 19, which is mounted on the bottom of the nursing chamber body. Preferably, the bottom shell 19 is sealed to the bottom of the nursing chamber body. The bottom shell 19 includes a receiving cavity 194, in which one end of the first electrode 141 and the second electrode 142 are received, and the other end extends through the bottom of the nursing chamber into the nursing chamber. One end of the third electrode 151 is received in the receiving cavity, and the other end extends through the bottom of the auxiliary chamber into the auxiliary chamber. In this example, the first electrode 141 and the second electrode 142 are both sealed to the bottom of the nursing chamber, and the third electrode 151 is sealed to the bottom of the auxiliary chamber.

[0124] On the other hand, the present invention also provides a method for caring for contact lenses, specifically including the following steps:

[0125] S1: Pour chloride ion-containing solution into the nursing chamber and the auxiliary chamber. A cation exchange membrane is set between the nursing chamber and the auxiliary chamber. At least a first electrode and a second electrode are set in the nursing chamber, and a third electrode is set in the auxiliary chamber. The contact lens is placed in the chloride ion-containing solution in the nursing chamber.

[0126] S2: Connect the first and third electrodes to the power supply. The first electrode is the cathode, and the third electrode is the anode. An oxidation reaction occurs at the third electrode, which removes Cl- from the chloride ion solution in the auxiliary chamber. - Electrolysis produces Cl2, which dissolves in the solution to generate HCl and HClO. A reduction reaction occurs at the first electrode, which electrolyzes H2O in the chloride-containing solution within the nursing chamber to produce H2 and OH-. - The cation exchange membrane provides an alkaline environment within the care chamber.

[0127] S3: After step S2 has reacted for a period of time, disconnect the power supply to the first and third electrodes, and connect the power supply to the first and second electrodes. One of the first and second electrodes is the anode, and the other is the cathode. The cathode electrolyzes the H2O in the solution to produce H2 and OH-. - The anode will react with Cl in the solution. - Electrolysis produces Cl2, which reacts with sodium hydroxide in the solution to produce Cl. - and ClO - The ClO - It can sterilize and degrade proteins on contact lenses. Under the action of the electric field force formed between the anode and cathode, the proteins on the contact lens move towards the electrode with the opposite charge, thereby achieving sterilization and protein removal of the contact lens.

[0128] Step S2 ensures that the solution in the care chamber is in an alkaline environment. This guarantees that when the first and second electrodes in the care chamber are working, NaClO is easily generated and HClO is not easily generated, thus reducing the adverse effects of HClO on lens fading and material properties.

[0129] Step S2 ensures that the solution in the care chamber is in an alkaline environment. This guarantees that when the first and second electrodes in the care chamber are working, NaClO is easily generated and HClO is not easily generated, thus reducing the adverse effects of HClO on lens fading and material properties.

[0130] Preferably, in step S3, when the pH value in the nursing chamber is between 8 and 12.5, the power supply to the first electrode and the third electrode is disconnected, and the power supply to the first electrode and the second electrode is connected.

[0131] Preferably, the chloride ion-containing solution is a NaCl solution. More preferably, the NaCl solution is a 0.9% (w / w) physiological saline solution. More preferably, the pH value of the NaCl solution is 7.

[0132] In a preferred embodiment, in step S2, the power-on voltage of the first electrode and the third electrode is not less than 1.1V, the stable voltage of the first electrode and the third electrode after power-on is 3.5-7.5V, and the power is disconnected after the first electrode and the third electrode react for 2-11 minutes.

[0133] In step S3, the power-on voltage for connecting the first and second electrodes is not less than 1.1V, and the stable voltage after connecting the first and second electrodes is 3.5-6.5V, controlling the ClO in the solution. - The mass concentration is 0.01%-0.4%, and the cleaning and sterilization of the contact lens is completed after the first electrode and the second electrode react for 10-30 minutes.

[0134] In step S2, after the first electrode and the third electrode are connected to the power supply, the first electrode or the second electrode becomes the cathode and the third electrode becomes the anode. The following reaction occurs at the cathode and the anode:

[0135] Cathode: 2H₂O + 2e⁻ - =H2↑ + 2OH -

[0136] Anode: 2Cl - -2e - →Cl2↑

[0137] Cl₂ + H₂O = HCl + HClO

[0138] In step S3, after the power is turned on at the first and second electrodes, the following reactions occur at the cathode and anode:

[0139] Cathode: 2H₂O + 2e⁻ - =H2↑ + 2OH - (I)

[0140] Anode: 2Cl - -2e - →Cl2↑ (Ⅱ)

[0141] Cl₂ + H₂O = HCl + HClO (III)

[0142] The obtained HClO will undergo the following reaction:

[0143] HCl + NaOH = NaCl + H₂O (IV)

[0144] HClO + NaOH =NaClO + H2O (Ⅴ)

[0145] NaClO + H₂O = HClO + NaOH (VI)

[0146] When a chloride-containing solution is in an alkaline environment, the ClO in the solution... - It mainly exists in the form of NaClO. Because in an alkaline environment, the dynamic equilibrium of reaction (VI) shifts to the left, resulting in a higher NaClO concentration and a lower HClO concentration. NaClO's bactericidal and protein-removing effects are relatively mild, and sodium hypochlorite has poor bleaching properties under alkaline conditions, thus preventing lens fading. The ClO in NaClO... - Ions can kill bacteria and degrade proteins, and with the help of electrophoresis, they can remove proteins. HClO has a bactericidal effect, but it also has a bleaching effect. High concentrations of HClO can cause lens fading, while lower concentrations greatly reduce its impact on contact lens color.

[0147] Preferably, the second and third electrodes are chlorine-evolving electrodes. In the example, the first electrode is also a chlorine-evolving electrode. In a chloride-ion-containing solution, an oxidation reaction occurs at the anode, releasing chlorine gas from the chloride ions in the solution. Chlorine-evolving electrodes have strong corrosion resistance, high chlorine and acid resistance, good stability, good oxidation resistance, and long service life. They can prevent the anode itself from reacting or producing other products that could contaminate the electrolyte or cathode products. They allow for easy removal of air bubbles between electrodes and on the electrode surface, effectively reducing the voltage in the electrolytic cell. They are easy to manufacture and have a high degree of precision. Generally, metal electrodes are mainly ruthenium-based, iridium-based, and platinum-based. Other inert electrodes (such as graphite and graphene materials) can also be used as chlorine-evolving electrodes, provided that the material's morphological stability is ensured. The electrode substrate is preferably a titanium alloy substrate or a platinum-plated substrate. The first and second electrodes in the care chamber are preferably symmetrically distributed on both sides of the care chamber, with both electrodes close to the side wall of the care chamber for better protein removal. In the example, both the first electrode and the second electrode are probes or electrode sheets. Of course, this patent is not limited to this and can be adjusted as needed.

[0148] In a preferred embodiment, step S4 is also included;

[0149] S4: After completing step S3, rinse the contact lenses with sterile saline or a multi-purpose eye-safe solution. Ideally, after rinsing, apply lubricant to the concave side of the contact lens before wearing it.
